In this note we report a new series of data on Dolichopodainae and Troglophilinae cave crickets of Turkey, after an extensive survey conducted between the years 2006 and 2010 in the main Anatolian cave systems. These new data, including the identifications of some undescribed taxa, are discussed in the framework of climate regions, vegetation and karst distribution of Turkey, contributing to the study of diversity and geographical distribution of Rhaphidophoridae cave crickets from Turkey.

The aim of this study was to determine of the evolutionary relationships of the TurkishDolichopodaspecies, and to define and clarify the systematics of the group in Anatolia. For this purpose, we have examined some 27 populations of the genusDolichopodafrom Anatolia and adjacent regions (Caucasia and the Greek islands). A total of 532 bp of the mitochondrial 16S rDNA gene was sequenced in order to clarify the phylogenetic relationships of the genus. Five main clades can be distinguished and well-supported by phylogenetic analyses. In these clades, the results obtained from Samos Island and Anatolia are remarkable. In contrast to some previous studies, our results point to an Aegean origin of the AnatolianDolichopodaspecies. According to the mitochondrial 16S rDNA divergence data, the current distribution of the genetic diversity was affected by ancient central lake system, habitat types, Messinian period and Plio-Pleistocene characterized by alternating dry/cold and warm/humid stages.

Descriptions of a new species of Tettigoniinae; Psorodonotus suphani sp. n. from Turkey were given. The relationships between the new species and closest taxa (morphologically and geographically) were evaluated by using morphological characters. Ultimately, some remarkable points of the distribution pattern of the species were presented.

The genus Saga is a genus of generally large predatory bush-cricket species. It includes 13 taxa in the Palaearctic region. In this research, eight species belonging to Saga (Tettigoniidae, Saginae) were sampled during field studies in different regions of Anatolia of Turkey between 2010 and 2018 (except one specimen). The bioacoustic parameters of these species recorded during the field or in laboratory conditions and the male calling song descriptions, as well as the oscillographic illustrations and distribution maps are given. A new population of Saga found from the South-Eastern Taurus (Hakkari province), which is affiliated to a new species and shows similarity to S. ephippigera, along with the morphological and bioacoustical descriptions of Saga hakkarica sp. n. Şirin & Taylan from Turkey, are also given. The relationships between the new species and the closest taxa are discussed using morphological and bioacoustical characters. The structural investigations of the male calling songs reveal three different bioacoustic groups affiliated to eight Anatolian Saga species; as (i) Ephippigera group (S. syriaca + (S. ephippigera + Saga hakkarica), (ii) Natoliae group (S. natoliae + (S. beieri + (S. longicaudata + S. puella) and (iii) S. cappadocica.
