Review of the Lithoscirtus genus group (Orthoptera, Acrididae, Proctolabinae) with description of new species

Abstract

The genera Lithoscirtus Bruner, 1908, Drymophilacris Descamps, 1976, and Drymacris Descamps & Rowell, 1978, occurring in Costa Rica and Panama, are reviewed and in part redescribed. Five species are described as new: Lithoscirius tesselatus sp. n., Drymophilacris glyphocerca sp. n., Drymophilacris nigrescens sp. n., Drymophilacris veraguensis sp. n., and Drymophilacris melanopsis sp. n. The previously unknown female of Drymacris panamae (Descamps) is described, and the species restored to Drymophilacris on the basis of female characters, giving the reinstated combination Drymophilacris panamae Descamps: Drymacris is thereby left monospecific, and is redescribed. New data on the distribution and coloration in life of previously described species are presented Keys to the three genera and to the species of Lithoscirtus and Drymophilacris are given.
