Gnominthus gen. nov., a new genus of crickets endemic to Papua New Guinea with novel acoustic and behavioral diversity (Insecta, Orthoptera, Gryllidae, Eneopterinae)

Abstract

The present study describes Gnominthus, a new genus of Eneopterinae crickets from New Guinea Island (Papua New Guinea), which belongs to the tribe Lebinthini. Descriptions focus on general morphology, male and female genitalia, and forewing venation. Bioacoustical analyses of the calling song and the description of the mating behavior are also provided. The novelties found here increase the idea hypothesized before that the Lebinthini may represent a very diverse group in terms of shapes, behaviors and acoustic signals.
