Japanese species of the genus Georissus are revised. Seven species, including two new, G. (Neogeorissus) takahashii sp. nov. and G. (Ne.) satoi sp. nov. are recognized. Georissus (Neogeorissus) sakaii Satô, 1972 and G. (Ne.) katsuoi Nakane, 1995 are synonymized with G. (Ne.) japonicus Satô, 1972. Based on the type series and additional specimens, three subgenera and seven species are (re)described with SEM micrographs of the external morphology and figures of male and female genitalia. The terminology of some structures of the head and the pronotum are redefined for convenience of taxonomy. A key to the Japanese species is also given.
The genera Pseudotraulia Laosinchai & Jago, 1980 and Bannacris Zheng, 1980 are revised based on the examination of types and additional materials. Bannacris punctonotus Zheng, 1980 is synonymized with Pseudotraulia cornuata Laosinchai & Jago, 1980 and Bannacris Zheng, 1980 with Pseudotraulia Laosinchai & Jago, 1980. The tribal placement of Pseudotraulia is discussed and the genus Pseudotraulia is transferred here from the tribe Mesambriini of the subfamily Catantopinae Brunner von Wattenwyl, 1893 to the subfamily Coptacrinae Brunner von Wattenwyl, 1893 which is not divided into tribes and consists of 22 genera distributed in the Afrotropical and Oriental regions.
