Description of Phelene reinschmidti from Ecuador with notes on the subfamily Lophotettiginae (Orthoptera, Tetrigidae)

Lophotettiginae Hancock, 1909, endemic to the Neotropics, is one of the most ill-known subfamilies of Tetrigidae. Until now, there have not been any hypothesis on its relationship with other subfamilies. Lophotettiginae comprise only two genera, Lophotettix Hancock, 1909 and Phelene Bolívar, 1906, both with an arduous taxonomic history. Here, we describe a new species, Phelene reinschmidti from Ecuador, and compare it with its congeners: P. turgida from Peru and P. maroon from French Guiana. We found the subfamily Lophotettiginae to most closely resemble the Neotropical subfamily Metrodorinae, meaning that the two are likely related. We also provide a 3D scan of the holotype, a first for Tetrigidae. The 3D model contains all the important taxonomic characters and much more data could be extracted in the future using artificial intelligence-assisted approaches.
