“The species’ striking colouring protects it from birds that prey on insects. They do not snatch the wasp sitting on the tree trunk as they think it will taste bad or that it is dangerous.”
Parasitoid wasps (Hymenoptera) are one of the most species rich animal taxa on Earth, but their tropical diversity is still poorly known. Now, scientists have discovered the Dolichomitus meii and Polysphincta parasitoid wasp species previously unknown to science in South America. The new species found in the rainforests entice with their colours and exciting habits. Researchers at the University of Turku have already described 53 new animal species this year.
Researchers at the Biodiversity Unit of the University of Turku, Finland, study insect biodiversity particularly in Amazonia and Africa. In their studies, they have discovered hundreds of species previously unknown to science. Many of them are exciting in their size, appearance, or living habits.
“The species we have discovered show what magnificent surprises the Earth’s rainforests can contain. The newly discovered Dolichomitus meii wasp is particularly interesting for its large size and unique colouring. With a quick glance, its body looks black but glitters electric blue in light. Moreover, its wings are golden yellow. Therefore, you could say it’s like a flying jewel,” says Postdoctoral Researcher Diego Pádua from the Instituto Nacional de Pesquisas da Amazônia (INPA) in Brazil, who has also worked at the Biodiversity Unit of the University of Turku.
Dolichomitus parasitoid wasps are parasitic on insect larvae living deep in tree trunks. They lay a single egg on the insect larva and the wasp hatchling eats the host larva as it develops.

“The ovipositor of the Dolichomitus meii wasp is immensely long. It sticks the ovipositor into holes in the wood and tries to find host larvae inside. The species’ striking colouring protects it from birds that prey on insects. They do not snatch the wasp sitting on the tree trunk as they think it will taste bad or that it is dangerous,” says Professor of Biodiversity Research Ilari E. Sääksjärvi from the University of Turku.
Polysphincta Parasitoid Wasps Manipulate the Behaviour of the Host Spider
At the same time as the publication on the Dolichomitus meii species, the researchers published another research article on South American wasp species. The article describes altogether seven new wasp species belonging to the Polysphincta genus.

The Polysphincta parasitoid wasps are parasitic on spiders. The female attacks a spider in its web and temporarily paralyses it with a venomous sting. After this, the wasp lays a single egg on the spider, and a larva hatches from the egg. The larva gradually consumes the spider and eventually pupates.
“The wasps that are parasitic on spiders are extremely interesting as many of them can manipulate the behaviour of the host spider. They can change the way a spider spins its web, so that before its death, the spider does not spin a normal web to catch prey. Instead, they spin a safe nest for the parasitoid wasp pupa,” describes Professor Sääksjärvi.
Researchers at University of Turku Have Already Discovered 53 New Species This Year
The new species are often discovered through extensive international collaboration. This was also the case with the newly published studies.
“For example, the discovery of the Dolichomitus meii species was an effort of six researchers. Moreover, these researchers all come from different countries,” says Professor Sääksjärvi.
The work to map out biodiversity previously unknown to science continues at the University of Turku and there are interesting species discoveries ahead.
“I just counted that, in 2021, the researchers of the Biodiversity Unit at the University of Turku have described already 53 new species from different parts of the globe – and we’re only halfway through the year,” Sääksjärvi announces cheerfully.

New species named after famous novelist Neil Gaiman, musician and human rights activist Peter Gabriel and singer-songwriter Brandi Carlile are among thirty-three new trapdoor spiders described from across North and South America. Following the discovery, published in the openly accessible, peer-reviewed scholarly journal ZooKeys, the known species in the genus Ummidia increased more than twice.
In a recent revision of the trapdoor spider genus Ummidia completed at the University of California, Davis, co-authors Dr. Rebecca Godwin (Piedmont University, GA) and Dr. Jason Bond (University of California, Davis, CA) described 33 new species found throughout North and South America. Their study is published in the openly accessible, peer-reviewed scholarly journal ZooKeys. A number of these species were named after popular artists, including Neil Gaiman, Peter Gabriel and Brandi Carlile.
“I think anything we can do to increase people’s interest in the diversity around them is worthwhile and giving species names that people recognize but that still have relevant meaning is one way to do that,” says Dr. Godwin.

The newly described trapdoor spider Ummidia brandicarlileae is named after singer-songwriter and activist Brandi Carlile, and occurs in Yucatán, Mexico, where Carlile’s annual Girls Just Wanna Weekend Festival is held. The event was created to counter the lack of female representation at mainstream music festivals.

Similarly, Ummidia neilgaimani is named after fantasy and horror writer, Neil Gaiman, author of a number of fantasy and horror books with spider-based characters, and a particular favorite of Dr. Godwin.

In addition to these pop culture references, Godwin and Bond named several species in honor of various people and places. The Pine Rockland trapdoor spider, found in southern Florida, is named after the critically endangered pine rockland habitat in which it is found. Ummidia paulacushingae is named for Dr. Paula Cushing, long-time collaborator and friend of Bond and friend, and mentor to Godwin.
With the names of the new to science species, the authors were also able to shed light on lesser-known historical figures. Ummidia bessiecolemanae is named for Bessie Coleman (1892–1926), the first African American and Native American woman to obtain her pilot’s license.
Trapdoor spiders are unique compared to most of the spiders that we are familiar with in that they don’t use silk to make a web. Instead, they live in burrows lined with silk and covered with a “trapdoor”.
Trapdoor spiders in the genus Ummidia are actually very widespread—they can be found from Maryland west to Colorado through Mexico and Caribbean as far south as Brazil. However, because they spend most of their lives underground, people rarely ever encounter a trapdoor spider. When trapdoor spiders are young, they leave their mother’s burrow and make one of their own. Females will spend their entire lives (which can be decades) in those burrows if they aren’t disturbed, but when a male spider matures (5 to 7 years of age), they emerge in search of females. This is when people are most likely to see them.
“I am continually blown away by how little we know about what is out there living on this planet with us. Most people don’t even realize they are sharing their space with these creatures literally right under their feet”
Dr. Rebecca Godwin
“Given the fact that these spiders tend to have very limited ranges and have very low dispersal, entire species can be winked out of existence without us ever knowing they were here, and I find that kind of heartbreaking. Documenting the diversity of groups like Ummidia gives us knowledge we need to appreciate and conserve the rich and diverse life that surrounds us.”

Michigan State entomologists have discovered dozens of new beetle species — and named some after iconic sci-fi heroines
The original Star Trek television series took place in a future when space is the final frontier, but humanity hasn’t reached that point quite yet. As researchers like Michigan State University entomologists Sarah Smith and Anthony Cognato are reminding us, there’s still plenty to discover right here on Earth.
Working in Central and South America, the duo discovered more than three dozen species of ambrosia beetles — beetles that eat ambrosia fungus — previously unknown to science. Smith and Cognato described these new species on June 16 in the journal ZooKeys.
The Spartans also selected an unusual naming theme named in deference to the female beetles who have helped their species survive and thrive by boldly going where they hadn’t before.
Many of the new species are named for iconic female science fiction characters, including Nyota Uhura of “Star Trek”; Kara “Starbuck” Thrace from the 2000s “Battlestar Galactica” TV series; and Katniss Everdeen from “The Hunger Games” books and movies.
The wing coverings of the C. katniss come to an arrowhead-like point, which reminded the researchers of Katniss Everdeen from “The Hunger Games,” shown below. “The Hunger Games” image courtesy of Lions Gate Entertainment Inc.
“But overall, our colleagues think it’s a good thing,” Cognato said. “It gives us a chance to talk about taxonomy — the science of classifying organisms — and about diversity.”
Understanding the world’s biodiversity is one of the major drivers of this and related research. Scientists estimate that there are 10 million nonbacterial species in the world and that humans have classified only about 20% of those.
“And some are lost before they’re ever discovered,” said Smith, who is the curator of the A. J. Cook Arthropod Research Collection. When people disrupt native ecosystems with farming and mining, for example, undiscovered species can face extinction before researchers know about them.
For this project, the team did some of its field work in Peru, where illegal gold miners can be particularly devastating to forests. “They’re turning the forest into a wasteland” Smith said. “It may never recover.”
Working in such threatened areas, Smith and Cognato are helping identify beetle species before it’s too late, as well as characterizing a rich variety of physical traits and behaviors.
To be clear, they did this field work long before the pandemic struck, starting around 2008. But it takes time to perform the thorough investigations required to ensure that a species is indeed distinct from its closely related cousins.
“With South America, it can be really hard to know whether a species is new or not, just because the fauna is so poorly studied,” Smith said.
With the stay-at-home orders in effect, she and Cognato had time to focus on projects that had been simmering on the backburner, such as this one that details ambrosia beetles they had collected belonging to the genus Coptoborus.
These tiny beetles make their homes by boring into trees. Once inside, they sustain their nests by cultivating fungus that serves as food. There, a mother produces many female offspring and one or two dwarfed males. The main job of those males is to mate with their sisters, creating a new generation of females prepared to disperse and produce a new brood. This all leads to another reason for studying these beetles: they can become pests.
These females arrive at trees ready to bore inside, start a fungus farm and reproduce. Though most prefer to nest in dead or dying parts of trees, some can attack fully healthy trees that are ecologically and economically important. For example, there are species within the genus known to attack balsa trees in Ecuador, the world’s leading exporter of balsa wood.
And if tree-dwelling beetles find their way into nonnative habitats, they can pose large threats to trees that have no natural defenses against the insects. Michiganders are all too familiar with the emerald ash borer, which has claimed millions of ash trees in the state. Another nonnative species of fungus-farming beetle devastated redbay laurels and avocado trees in the Southern U.S.
By identifying species abroad, in their native habitats, researchers including Smith and Cognato are helping the U.S. better prepare for if and when a new pest shows up here. And, historically speaking, Coptoborus beetles are hardy travelers.
The researchers thought the C. starbuck‘s appearance gave it a tough persona, leading them to name it for Kara “Starbuck” Thrace from “Battlestar Galactica,” shown on the right. “Battlestar Galactica” image courtesy of NBC Universal.
Their ancestors originated about 20 million years ago, likely in Southeast Asia, before emigrating and making homes across much of the tropics.
“That’s one of the reasons we chose to name them after female sci-fi characters. Not to anthropomorphize too much, but you have these adventurous females that were blown off their log or had their wood-encased home thrown into the ocean by a mudslide,” Cognato said. If these mated females made it to a new land, they could start a new population, allowing the species to proliferate.
“Along the way, there were so many ways to die, but they ended up colonizing an entire continent.”
Fast forward to now and there are thousands of ambrosia beetle species, including more than 70 of the Coptoborus genus — and counting. In christening the new beetles, Smith and Cognato got some inspiration by finding similarities between the beetle and its namesake.
For instance, the C. uhura was given its name because its reddish color, reminiscent of the uniform worn by Nichelle Nichols’s Uhura character in the original “Star Trek” TV series.
The C. uhura’s reddish hue reminded the researchers of the uniform worn by Lt. Uhura in the original “Star Trek” television series, shown below. “Star Trek” image courtesy of CBS Studios Inc.
And Sigourney Weaver’s Ellen Ripley character in the “Alien” film franchise had a shaved head in the movie “Alien 3.” One of the beetles, now named C. ripley, was also glabrous, or without hair.
The C. ripley is glabrous, which means hairless, reminding the researchers of Ellen Ripley and her shaved head in “Alien 3,” shown on the right. “Alien 3” image courtesy of Twentieth Century Fox.
Other names were selected because the duo just liked the characters and found them inspiring. For example, the C. scully beetle was named after Dana Scully, Gillian Anderson’s character on “The X-Files.”
The character is also behind what’s known as the “Scully Effect.” By showing a successful female scientist on TV, the show helped raise awareness of science, technology, engineering and mathematics — or STEM — professions among young women.
In their paper, Smith and Cognato wrote, “We believe in the ‘Scully Effect’ and hope future female scientists, real and fictional, continue to inspire children and young adults to pursue STEM careers.”
Smith and Cognato also took the opportunity to name some beetles in honor of real-life people who have made an impact on their work and their lives.
For example, the C. erwini, is named after a renowned entomologist and friend Terry Erwin, who passed away in 2020. Erwin helped popularize a technique called canopy fogging to collect beetle specimens living in treetops.
Coptoboruserwini
“Without his dedication to canopy fogging, this species and most of those described in this publication may never have been discovered,” Smith and Cognato wrote in their study, which is part of a special issue in memory of Erwin, who was also editor-in-chief of ZooKeys.
Also, the C. bettysmithae is named after Smith’s grandmother, Catherine “Betty” Smith. Sarah remembers Betty’s incredible strength in battling cancer and her help fostering her granddaughter’s scientific interest.
Some of the beetles were named for real-life inspirations, like the C. bettysmithae, named for Sarah Smith’s grandmother, Catherine “Betty” Smith.
“My grandmother supported me a lot with entomology,” Smith said. “I used to spend many weekends with her, and she’d take me out to catch dragonflies.”
Now, she and Cognato are out catching and characterizing insects that are new to science. In doing so, they’re helping protect native ecosystems, painting a more complete picture of the planet’s bountiful biodiversity and even drawing some attention to the power of naming and classifying things.
“Taxonomy was probably one of the first sciences of humans. You can find evidence of it throughout history and across cultures,” Cognato said.
This naming likely started so humans could easily share information about which plants were safe to eat and which animals were dangerous. This is still valuable information today, but naming has evolved to help us appreciate even more dimensions of life on Earth.
Think about being a kid in a park or backyard, Cognato said, and the innate desire to know and name the animals there, say, robins or squirrels. Classification builds connection.
“It helps us communicate and it helps us live better,” Cognato said. “It helps us understand the world and biodiversity.”

One of the main threats to biodiversity conservation is not recognizing the uniqueness of species – without a formal name, a species cannot be protected properly. Tardigrades – microorganisms also known as water bears or moss piglets – are no exception. When we were faced with two new species, we took the chance to describe them and add a small piece of information to the biodiversity of those tiny animals.
Thanks to the generosity of my research group principal investigator (Sara Calhim) and the second author’s (Daniel Stec) academic supervisor (Lukasz Michalczyk), who made available to us their spaces and instrumentations, we were able to give a formal name and description to two marvelous tardigrade species.

When describing species, researchers have almost complete freedom to express their creativity or gratitude in bestowing them with names. We decided to honour two people: Dr. Anne Winters, who collected the sample where one of the new species – Macrobiotus annewintersae, was found, and the singer Alexander Rybak with Macrobiotus rybaki.
While routinely examining samples for tardigrades, we stumbled upon tardigrade eggs that didn’t look like any described species. Macrobiotus annewintersae eggs have many conic projections on their surface (called processes) that are topped by about 6 small and stubby tentacles, whereas the processes of Macrobiotus rybaki look like spikes topped with a very tiny dish.
The choice to dedicate the new species to Alexander Rybak is the fruit of our (mine and Daniel’s) passion for the Eurovision Song Contest. We are both fans of this very popular, diverse and cheerful song contest, and we wanted to honour it with a reference to one of its most iconic winners. Rybak’s song Fairytale, which won the 2009 edition, is immediately recognized by any Eurovision Song Contest enthusiast. Our research article, where we describe the two newly found tardigrades,was published in the open-access journal Zoosystematics and Evolutionon 19 May, right in the middle of the semi-finals for this year’s Eurovision Song Contest.
This is not the first instance that a tardigrade species is named after a singer. One species, Barbaria madonnae, was named in 2006 after the singer and performer Madonna.
We hope that naming tardigrade species after popular singers and artists will help popularize them and bring the broad public attention to their conservation.

Do freshwater snails make good tennis players? One of them certainly has the name for it.
Enter Travunijana djokovici, a new species of aquatic snail named after famous Serbian tennis player Novak Djokovic.

Slovak biospeleologist Jozef Grego and Montenegrin zoologist Vladimir Pešić of the University of Montenegro discovered the new snail in a karstic spring near Podgorica, the capital of Montenegro, during a field trip in April 2019. Their scientific article, published in the open-access, peer-reviewed journal Subterranean Biology, says they named it after Djokovic “to acknowledge his inspiring enthusiasm and energy.”
“To discover some of the world’s rarest animals that inhabit the unique underground habitats of the Dinaric karst, to reach inaccessible cave and spring habitats and for the restless work during processing of the collected material, you need Novak’s energy and enthusiasm,” the researchers explain.
T. djokovici has a milky-white shell in the shape of an elongated cone and is adapted to live in the underground habitats of the Dinaric karst. It is part of Hydrobiidae, a very diverse family of small to tiny snails – also known as mud snails – inhabiting fresh or brackish water, including caves and subterranean habitats.
The type locality where Tavunijana djokovici was found.
This is the first member of the genus Travunijana so far to be discovered in the Skadar Lake basin, and the only one found outside of the Trebišnjica river basin in Herzegovina, which points to the enigmatic distributional range of these snails across the Dinaric underground habitats. Where they came from, and how, remains a mystery.
Because of its small area of occupancy, T. djokovici is assessed as Vulnerable, according to the IUCN Red List of Threatened Species. Subterranean ecosystems, the authors of the new species emphasise, are extremely vulnerable to human-driven environmental changes, and, being obscure, they’re often overlooked during conservation efforts.

While the new Coronavirus will, hopefully, be effectively controlled sooner rather than later, its latest namesake is here to stay – a small caddisfly endemic to a national park in Kosovo that is new to science.
The new species Potamophylax coronavirus
Potamophylax coronavirus was collected near a stream in the Bjeshkët e Nemuna National Park in Kosovo by a team of scientists, led by Professor Halil Ibrahimi of the University of Prishtina. After molecular and morphological analyses, it was described as a caddisfly species, new to science in the open-access, peer-reviewed Biodiversity Data Journal.

Ironically, the study of this new insect was impacted by the same pandemic that inspired its scientific name. Although it was collected a few years ago, the new species was only described during the global pandemic, caused by SARS-CoV-2. Its name, P. coronavirus, will be an eternal memory of this difficult period.

In a broader sense, the authors also wish to bring attention to “another silent pandemic occurring on freshwater organisms in Kosovo’s rivers,” caused by the pollution and degradation of freshwater habitats, as well as the activity increasing in recent years of mismanaged hydropower plants. Particularly, the river basin of the Lumbardhi i Deçanit River, where the new species was discovered, has turned into a ‘battlefield’ for scientists and civil society on one side and the management of the hydropower plant operating on this river on the other.

The small insect order of Trichoptera, where P. coronavirus belongs, is very sensitive to water pollution and habitat deterioration. The authors of the new species argue that it is a small-scale endemic taxon, very sensitive to the ongoing activities in Lumbardhi i Deçanit river. Failure to understand this may drive this and many other species towards extinction.
Interestingly, in the same paper, the authors also identified a few other new species from isolated habitats in the Balkan Peninsula, which are awaiting description upon collection of further specimens. The Western Balkans and especially Kosovo, have proved to be an important hotspot of freshwater biodiversity. Several new insect species have been discovered there in the past few years, most of them being described by Professor Halil Ibrahimi and his team.
In 2001, the famous herpetologist Joseph B. Slowinski died from snakebite by an immature black-and-white banded krait, while leading an expedition team in northern Myanmar. The very krait that caused his death is now confirmed to belong to the same species identified as a new to science venomous snake, following an examination of samples collected between 2016 and 2019 from Yingjiang County, Yunnan Province, China.

The researchers decided to name the new species Bungarus suzhenae – Suzhen’s krait, after the mythical figure of Bai Su Zhen (白素贞) – a powerful snake goddess from the traditional Chinese myth ‘Legend of White Snake (白蛇传)’.
The legend says that, after thousands of years of practicing magic power, the white snake Bai Su Zhen transformed herself into a young woman and fell in love with the human man Xu Xian. Together, they ran a hospital, saving lots of human lives with medicine and magic. However, this love between goddess and human was forbidden by the world of the gods and, eventually, Bai Su Zhen was imprisoned in a tower for eternity. Since then, the Chinese regard her as a symbol of true love and good-heartedness.

“The black-and-white banded krait is one of the snakes most similar to the white snake in nature, so we decided to name it after Bai Su Zhen,” say the authors.
In fact, the discovery of Suzhen’s krait was inspired by another accident from 2015, when the Chinese herpetologist Mian Hou was bitten by a black-and-white banded krait in Yingjiang. “It hurt around the wound, and the skin around it turned dark,” said the unfortunate man, who luckily survived.

The authors of the present study realized that the bite was different from those of the many-banded krait B. multicinctus, which go without clear symptoms or pain around the wound. This clue eventually led to the discovery of Suzhen’s krait.
Because kraits are highly lethal, understanding their species diversity and geographic distribution is vital for saving human lives. Thanks to adequate description and classification of deadly snakes, research on venom, antivenom development and proper snakebite treatment can advance more rapidly.
The new study makes it easier to distinguish between krait species from China and adjacent southeastern Asia. “Three species of the black-and-white banded kraits from China were previously put under the same name – many-banded krait, which would hinder appropriate medical treatment,” the authors point out. Additionally, they suggest that antivenom for the many-banded krait be reevaluated accordingly.
The Bale Mountains in south-central Ethiopia are considered to be one of the most unique centers of endemism, with an extraordinary number of plants and animals that can only be found there. Numerous species are already known from this Afromontane high-elevation plateau, making it a biodiversity hotspot, but ongoing research continues to reveal the presence of so far unknown and undescribed organisms.

Zoologists Thore Koppetsch and Benjamin Wipfler of the Research Museum Alexander Koenig in Bonn, Germany, and Petr Nečas from the Czech Republic, describe one such species: a new small-sized chameleon living on the edge of the forest. Their findings were published in the open-access, peer-reviewed life science journal Zoosystematics and Evolution.
There were already two species of the chameleon genus Trioceros known to be restricted to the Bale region when Thore Koppetsch and his colleagues discovered another unique representative of this group from the northern slopes of the Bale Mountains. Interestingly, this new chameleon is considered to be part of a species complex of the wide-spread Ethiopian Chameleon Trioceros affinis. Previous studies have indicated divergence between its different populations across the Ethiopian Highlands – with some of them separated by the northern extension of the Great Rift Valley, which also shaped the evolution of early humans.

The new chameleon, Trioceros wolfgangboehmei, has a special name. It honours the scientific work of Wolfgang Böhme, senior herpetologist at the Zoological Research Museum Alexander Koenig in Bonn, and his passion for chameleons and other reptiles.
Apart from its biogeographical patterns, the new species also has a characteristic appearance, displaying enlarged spiny scales on its back and tail that form a prominent crest. It usually lives on small trees and bushes at an altitude of above 2,500 m above sea level.

“Given the variation in colour patterns and morphology between different populations of these chameleons in Ethiopia, it is likely that these groups still bear a higher hidden diversity than expected, which might be revealed by further ongoing investigations.”
Thore Koppetsch
Furthermore, the research team urges for sustainable preservation and conservation of its habitat to mitigate the impact of human activity.

Happy Taxonomist Appreciation Day! On this day dedicated to the scientists who name, define and classify all living things, the World Register of Marine Species (WoRMS) also honors discoveries in marine biology by posting a “Top 10” of the marine species discovered throughout the year. The year 2020 saw fascinating discoveries in the world of sea life, and, once more, species first described in Pensoft‘s open-access journal ZooKeys made it to the Top 10!
Deep in the Pacific Ocean, researchers found not one, not two, but four species of iridescent scale worms. They have yet to figure out why these critters shimmer, but the Internet was already calling them ‘Elvis worms’ or ‘glitter worms’, because their scales evoked associations with Elvis’ shiny costumes. One species was even formally named Peinaleopolynoe elvisiin honor of the King of Rock ‘n’ Roll.
These gorgeous creatures are called a scale worm, and scientists found, among other places: ON UNDERWATER VOLCANOES, near scalding hydrothermal vents and around THE BODIES OF DEAD WHALES. These worms = badass. And they're hungry… Study: https://t.co/4T7wfqZiZIpic.twitter.com/FGSqoza9Nm
— Open Ocean Exploration (@RebeccaRHelm) May 13, 2020
It was however one of the other three species, Peinaleopolynoe orphanae, that made it to the Top 10 – because, in the words of the committee, it has “both the most stunning iridescence and the feistiest temperament!”
P.orphanae was first collected from a hydrothermal vent in the Gulf of California at a depth of 3700 m and named after geobiologist Victoria Orphan. The first part of its name, Peinaleopolynoe, comes from a Greek word for hungry, in reference to the attraction of these worms to food falls.
Surprisingly, Peinaleopolynoe orphanae engage in fights between each other before the eyes of the researchers! In what has never been seen in scale worms before, the scientists recorded a “face-off”, where two individuals kept attacking one another back and forth for several minutes.
The Red Pipefish, Master of Disguise
The Red Wide-Bodied Pipefish (Stigmatopora harastii) dwells in New South Wales, Australia, at 10-25 m depth, and is so good at camouflage that you might have a hard time spotting it even when you’re looking straight at it. It was first reported by underwater photographers in Jervis Bay in 2002, but was only described as a new species in 2020 by scientists from the Australian Museum, California Academy of Sciences, Burke Museum, and the University of British Columbia.
This curious new fish associates with red algae or finger sponges, which allows it to stay hidden in plain sight. It is colored bright red, but curiously that only helps it to go unnoticed. Oriented vertically or at an angle, it camouflages itself among the red algae. Virtually indistinguishable from its surroundings, it only occasionally darts out of its cozy cover to munch on small copepods and shrimp.
Stigmatopora harastii
Stigmatopora harastii was named after David Harasti, one of the first people to recognize it as a new species and a pronounced fan of the Stigmatopora genus. According to the research paper, “David has stated he counts green pipefish to fall asleep.” We don’t know how he feels about red pipefish, but this one charms with both looks and skills, so we hope it becomes one of his favorites.

Researchers believe the red pipefish might have a wider distribution in New South Wales and possibly New Zealand – it can be very hard to detect because of its preferred depth range and its remarkable camouflaging ability.
The 10 remarkable new marine species from 2020 listed by WoRMS are a celebration of all wonderful and sometimes even quite weird creatures that dwell in the sea, and a reminder of how important it is to explore and protect marine life. Here’s to another year of fun little creatures and amazing scientific discoveries!
A new species of tiny cave snail that glistens in the light and has a muffin-top-like bulge, was discovered by Marina Ferrand of the French Club Etude et Exploration des Gouffres et Carrières (EEGC), during the Phouhin Namno caving expedition in Tham Houey Yè cave in Laos in March 2019. The new species, named Laoennea renouardi was described in the open-access, peer-reviewed journal Subterranean Biology.

The new species, Laoennea renouardi, is 1.80 mm tall and is named after the French caver,Louis Renouard, who explored and mapped the only two caves in Laos known to harbor this group of tiny snails. Only two species of Laoennea snail are known so far, L. carychioides and now, L. renouardi.

“The discovery and description of biodiversity before it disappears is a major priority for biologists worldwide. The caves in Laos are still largely underexplored and the snails known from them remain few in number,”
points out Dr. Jochum.
The fact that two species of tiny cave snails of the same group were found in two caves located in two independent karstic networks 3.4 km apart, caused the authors to question evolutionary processes in these underground hotspots of biodiversity. The authors hypothesise that the two caves might have been connected during the Quaternary, around 100–200 thousand years ago. In time, the river Yè might have formed a barrier, thus disconnecting the cave systems and separating the populations. As a result, the snails evolved into two different species.
