Aryalidonta itishreea, a new genus and species of Thoradontini (Orthoptera, Tetrigidae) from Nepal honors the Emperor of Laughter

Abstract

Aryal’s Ten Avatar Groundhopper, Aryalidonta itishreea gen. et sp. nov., named in honor of the late Bhairav Aryal, an iconic Nepali satirist, is a new genus and species of Tetrigidae described as a part of the tribe Thoradontini. The species is native to Nepal, a country with a rich tetrigid fauna in need of taxonomic revisions. This monotypic genus can be easily separated from other Thoradontini genera by its enlarged proximal halves of middle femora, a peculiar lateral lobe morphology (small caudal protrusion in its caudal part and a sharp lateral tip), a triangular, anteriorly narrowing vertex, and by its unique head morphology. The species was observed in its natural habitat. It was found to harbor many color variations that are cryptic in nature. It feeds on detritus, algae, lichen, and moss. Specimens heavily infested by mites were found, as well as those in interaction with wasps (possibly Eulophidae), but the nature of the latter could not be determined.
