Rugabinthus, a new genus of Lebinthina (Orthoptera, Gryllidae, Eneopterinae) from New Guinea

Abstract

Brachypterous crickets from the monophyletic group of Lebinthina were traditionally grouped under the genus Lebinthus. However, the morphology and calling song are highly diversified, prompting the erection of numerous genera to reclassify the species. Based on the strong characteristic fold carrying the diagonal vein of the male forewing, a new genus of cricket from the subtribe Lebinthina is described: Rugabinthus gen. nov. This brachypterous genus is endemic to the island of New Guinea and nearby islands. We redescribe the type species Rugabinthus leopoldi (Chopard, 1931) comb. nov. and describe 12 new species, R. manokwari sp. nov., R. kencana sp. nov., R. maoke sp. nov., R. nabire sp. nov., R. albatros sp. nov., R. karimui sp. nov., R. yayukae sp. nov., R. biakis sp. nov., R. mamberamo sp. nov., R. tariku sp. nov., R. faowi sp. nov., and R. baduri sp. nov. We also transferred R. newguineae (Bhowmik, 1981) comb. nov. and provide a key to all known species of Rugabinthus gen. nov.
