Guest blog post: New ectoparasite records from Honduras came from bats recorded since 2015

Guest blog post by Manfredo Alejandro Turcios-Casco

Since its foundation in 2015, the research team “The Big Bat Theory” has filled important information gaps regarding bats and their ectoparasites in Honduras. We started as just bachelor students mist-netting bats in our university (Universidad Nacional Autónoma de Honduras- UNAH) in our free time. Then we studied a lot about their natural history, distribution, and ecology, and, without any financial support, we started to travel the country studying bats.

The early years of “The Big Bat Theory” research group

At that time, we did not know that many of those records, in the future, would be important for Honduras. After saving some money, we travelled to different departments of Honduras such as Francisco Morazán, Valle, Gracias a Dios, Comayagua, and Santa Bárbara. Then we found support from Marcio Martínez to get to know La Mosquitia, and we started studying bats in unexplored regions. Because of this initiative, we collaborated with bat ectoparasite specialist Gustavo Graciolli and bat specialist Richard Laval, which resulted in the publication of our research in the open-access, peer-reviewed journal Check List.

As a result of this project, we were able to register for the first time the Spinturnicidae family in Honduras with the species Periglischrus iheringi and P. ojastii, a new record of Basilia ortizi (Nycteribiidae), Aspidoptera delatorrei, Strebla matsoni (found hosting Artibeus jamaicensis for the first time), and Neotrichobius bisetosus (Streblidae). The latter, previously only known from Venezuela, is the record with the northernmost locality published to date. We managed to increase the number of species of bat ectoparasites in Honduras to 48, which is 33 more than in Paraguay and 65 less than in Peru.

Species of ectoparasites recorded for the first time in Honduras: A) Periglischrus iheringi (Spinturnicidae); B) Periglischrus ojastii (Spinturnicidae); C) Aspidoptera delatorrei (Streblidae); D) Trichobius yunkeri (Streblidae); E) Basilia ortizi (Nycteribiidae); F) Neotrichobius bisetosus (Streblidae); G) Strebla matsoni (Streblide).

We definitely consider that this still misunderstood group needs more research effort locally and in general. Considering the lack of knowledge, the chances of discovering new species for the region, new records for the country or region, as well as new discoveries about the relationship and interactions with their hosts, are high. The number of bat species registered for Honduras is a predictor of the number of ectoparasite species that may exist. We also consider “La Reserva de la Biosfera del Río Plátano” an important site for the study of ectoparasites of bats. This is the most important area in Honduras for bat research and conservation, not only because of its high biodiversity, but also because it is a poorly studied region.

“We are very motivated to have carried out this study on new records of ectoparasites in bats, since it is the first investigation we do on this taxon, but we are sure that it will not be the last, since we have already begun to collect new data in collaboration with experts on this topic. We are sure that new discoveries still await us in this area, and we are eager to make new contributions and enrich the information on this taxon in Honduras and the world.”

New gorgeous coffee tree species from Honduras is critically endangered

Amid the challenging terrain of north-western Honduras, where Dr. Kelly’s team faced rugged and steep forest areas cut across here and there by a few trails, a gorgeous tree with cherry-like fruits was discovered. Being about 10 metres (33 ft) high and covered with cream-colored flowers, it was quickly sorted into the Coffee family (Rubiaceae), but it was its further description that took much longer. Eventually, it was named Sommera cusucoana, with its specific name stemming from its so far only known locality, the Cusuco National Park. The study is available in the open-access journal PhytoKeys.

During a plant diversity study in the Cusuco National Park, conducted by Drs. Kelly, Dietzch and co-workers as a part of a broader survey by Operation Wallacea, an international organisation dealing with biodiversity and conservation management research programmes.

A couple of curious findings in the past decade provide a strong incentive to further work. The place turns out to be not only of high biodiversity, but to also contain rare and hitherto unknown plant and animal species.

For instance, the tree Hondurodendron (from Greek, ‘Honduras Tree’) and the herbaceous plant Calathea carolineae are another two endemic species discovered as a result of the Operation Wallacea survey.

In 2013, two individuals of another unknown, 10-metre high (33 ft) tree with cream-colored flowers and red, cherry-like fruits were found by Daniel Kelly and Anke Dietzsch from Trinity College, University of Dublin, Ireland. The two were aided by local guide Wilmer Lopez.

The multinational collaboration did not stop then and there. Although the scientists quickly figured that the tree belonged to the Coffee family, they needed some additional help to further identify their discovery. Thus, they were joined by two leading specialist in this plant group, first Charlotte Taylor from Missouri Botanical Garden and then David Lorence from the National Tropical Botanical Garden in Hawaii.

It was actually David who was the first to recognise the unknown tree as a member of theSommera genus, a group of nine known species of trees and shrubs. Later, the team decided to name the new plant Sommera cusucoana to celebrate its singular locality, the Cusuco National Park.

“Sadly, there has been extensive logging in the vicinity in recent years, and we fear for the future of our new species,” the authors stressed. “According to the criteria of the International Union for the Conservation of Nature (IUCN), it must be regarded as Critically Endangered.”

“We hope that the publication of this and other discoveries will help to galvanize support for the conservation of this unique and beautiful park and its denizens,” they concluded.
