The Genus Geckomima (Orthoptera: Eumastacidae: Morabinae)

Abstract

The known species of the genus Geckomima, a relatively robust, subarboreal member of the norabine grasshopper tribe Warramungini, are described, keyed, and their relationships discussed. Twelve species, brevicornis, lesueuri, handschini, brevirostris, gecko, drysdaleana, yampi, tindalei, pilbara, leopoldana, nepos, and arnhemana, are recognized (the last seven new) and two races within arnhemana. The genus is restricted to the Northern Territory and the northern half of Western Australia. G. handschini has an extensive distribution in the drier parts of the Northern Territory and adjacent Western Australia, while the remaining species occupy smaller areas to the north and west. All species are ostensibly allopatric, but all are probably in fact parapatric with their nearest neighbours.
