A research team from the Natural History Museum of Denmark has published a compelling new study in insect taxonomy in the open-access journal ZooKeys, officially establishing a new genus of rove beetle (Staphylinina): Luffy gen. nov. The inspiration for the name comes directly from Monkey D. Luffy, the iconic protagonist of the globally popular manga and anime One Piece.
Why Name a Beetle Genus “Luffy”?
The research team noted that naming the new genus Luffy was not merely for fun, but rather a direct reflection of the beetles’ highly recognizable morphological characteristics.
The species within this genus possess mandibles, antennae, and maxillary palps that are significantly longer and more slender than those of closely related groups. This uniquely elongated overall proportion immediately reminded researchers of Luffy’s rubber body abilities in One Piece, which allow him to freely stretch and expand.
Two New Beetles in the New Genus
Currently, two distinct species have been discovered and classified under this new genus: Luffy schillhammeri and Luffy nika.
The species Luffy schillhammeri was found in the broadleaf forests of Yunnan Province, China. The specific epithet of Luffy schillhammeri honors Dr. Harald Schillhammer of the Natural History Museum Vienna, recognizing his long-term and outstanding contributions to the research of rove beetles.
Luffy nika was discovered in Louang Namtha, northern Laos. The specific epithet “nika” originates from Luffy’s legendary Devil Fruit awakening, “Hito Hito no Mi, Model: Nika” (also known as Gear 5). This new species features striking white band-like hairs on its elytra and across much of its body, closely resembling Luffy’s classic, all-white, smoke-shrouded appearance during his Nika transformation.
Major Scientific Breakthrough: Filling a Key Evolutionary Gap in the Eucibdelus Lineage
Beyond its eye-catching name, this study holds high scientific value. The research team, consisting of PhD student Fang-Shuo Hu and Alexey Solodovnikov from the Natural History Museum of Denmark, systematically reviewed all known genera of the Ocypus-group.
They also included several groups whose taxonomic positions had long been questionable and controversial (such as Acupronotes, Apostenolinus, and Staphylinus). Through the examination of a large number of specimens and rigorous comparisons of subtle morphological features, the team successfully re-evaluated the phylogenetic relationships among these groups and put forward key findings.
The research team clearly identified the synapomorphies of the “Eucibdelus lineage” (such as the left mandible possessing dorsal ridge teeth and a completely sclerotized labrum). Interestingly, while the genus Luffy possesses these dorsal ridge teeth, its labrum is not completely sclerotized, and it carries several distinct traits of its own.
Based on this morphological evidence, the research team infers that the genus Luffy is highly likely to be the sister group to the entire Eucibdelus lineage. Highlighting that our understanding of this insect lineage is continuously evolving with new discoveries, the researchers note:
This genus exhibits a unique combination of characters intermediate between the Eucibdelus lineage and other members of the Ocypus-group.

This discovery successfully fills an important gap in the existing taxonomic framework, providing a new perspective on the evolutionary history of the subtribe Staphylinina.
Inspiring the Next Generation of Scientists
From manga inspiration to publication in a rigorous international scientific journal, the birth of the genus Luffy proves that scientific research can be both serious and highly engaging. The research team looks forward to closing the distance between science and the general public through such an accessible story, raising awareness about the importance of biological taxonomy, and attracting more of the younger generation to dive into biodiversity and taxonomic research with an adventurous spirit just like Luffy’s.
