A review of (Orthoptera, Tettigoniidae) from Crete, Gavdos, Gavdopoula, and Andikithira.

Being nocturnal, hiding in prickly bushes and shrubs during the day, species in Crete and its neighbouring islands are easily overlooked, and until now our knowledge about their distribution was based on some thirty sightings across 11 species. In this paper results are presented of a study of specimens collected between 1987 and 2020 by hand-catches and pitfall and fermenting traps on the Greek islands of Crete, Gavdos, Gavdopoula, and Andikithira. Diagnostic features of all known species are presented and illustrated with stacked images. An updated key to all species is provided. Tilmans & Odé, from Andikithira and southwestern Crete and Willemse & Kotitsa, from Mt. Dikti are described. Female , , and are described, and the female of is redescribed. Bioacoustics for Tilmans & Odé, ., , and are presented for the first time. is reported for the first time from Crete. A substantial amount of new distribution data for species on Crete is presented. The current distribution pattern and first analyses of phylogeny based on molecular data of species on Crete are discussed in relation to paleogeographical events.
