Taxonomic Revision of the South African Grasshopper Genus Euloryma (Orthoptera: Acrididae)

摘要

The South African flightless hemiacridine genus Euloryma is revised for the first time, with 21 new species described. The genus name Euloryma is a women novum, proposed because the genus Loryma Stal, 1878 (Orthoptera: Acrididae) is a junior homonym of the genus Loryma Walker, 1859 (Lepidoptera: Pyralidae). A detailed discussion of the rationale for this new name is provided. Species keys, a reference chart of species, extensive photography of external and internal morphology, and distribution maps are provided. Morphology figures labeled with internal and external terminology are included. Two provisional Euloryma species-groups are proposed: karoo species-group and the cederbergensis species-group. The majority of the karoo species-group members are found in succulent karoo biome, with one species in the grassland biome, whereas the majority of the cederbergensis species-group members are found in the fynbos biome. The new tribe name Dirshacrini is proposed, due to proposed changes in nomenclature; tribe members Hemiloryma, Dirshacris and Labidioloryma are photographed, a list of diagnostic differences is provided, and a key to the genera is given. The following new species are proposed: karoo species-group: ashleyi sp. nov.; carolynae sp. nov.;magna sp. nov.; browni sp. nov.; khoi sp. nov.; namaqua sp. nov.; san sp. nov.; mayi sp. nov.; zebrata sp. nov.; bonteboki sp. nov.; karoo sp. nov.; cederbergensis species-group: mirabunda sp. nov.; cederbergensis, sp. nov.; lapollai sp. nov.; tsitsikamma sp. nov.; waboom sp. nov.; solveigae sp. nov.; larsenorum sp. nov.; umoja sp. nov.; lyra sp. nov.; ottei sp. nov.
