A team of entomologists has named a newly identified genus of rove beetle "Luffy," after the elastic-limbed hero of the manga and anime series "One Piece," citing the insects' strikingly elongated mouthparts.
Researchers from the Natural History Museum of Denmark and the University of Copenhagen described the genus, along with two new species within it, in a study published in the open-access journal ZooKeys, according to a summary from the journal's publisher, Pensoft. The beetles' mandibles, antennae and maxillary palps are markedly longer and more slender than those of closely related genera — a proportion the authors said reminded them of Monkey D. Luffy, whose body in the story can stretch like rubber.
The naming, the researchers said, was not purely whimsical. Phys.org's report on the paper noted the elongated features represent a genuine, previously undescribed evolutionary lineage, and the pop-culture reference was chosen partly to make the finding more memorable outside specialist circles — a naming tradition with precedent in taxonomy, where new species have periodically been named after fictional and celebrity figures to draw public attention to biodiversity research.
Two species currently make up the genus. Luffy schillhammeri was collected in broadleaf forest in China's Yunnan province and is named in honor of Harald Schillhammer, a rove beetle specialist at the Natural History Museum Vienna. Luffy nika was found in Louang Namtha province in northern Laos; its species name nods to Luffy's in-story "Gear 5" transformation, nicknamed "Nika" in the manga.
Rove beetles form one of the largest and most diverse beetle families, with tens of thousands of described species worldwide, many still poorly documented in the biodiverse forests of Southeast Asia where both new Luffy species were found. The study's authors said further fieldwork in the region is likely to turn up additional relatives, and that formally naming and describing such lineages helps researchers track and protect insect diversity in habitats facing mounting deforestation pressure.
