Two new cryptic aberrant species of Rhacocleis Fieber 1853, living under stones in the mountains of Greece (Orthoptera, Tettigoniidae)

Abstract

We describe 2 new and closely allied tettigoniid species, recently discovered on mountain slopes in southwestern continental Greece. Though they differ in habitus, coloration, morphology (modified paraprocts) and habitat from most members of Rhacocleis, the new species have been arranged tentatively in this genus. Unknown morphological characters and faunistic data for some other poorly known Greek Rhacocleis species (R. ferdinandi Willemse & Tilmans 1987 and edentata Willemse 1982) are included.
