Abstract
Among the Anatolian Tettigoniinae (Orthoptera, Tettigoniidae) the genera Anterastes, Koroglus, Sureyaella and Rhacocleis are distinguishable from the others by presence of one pair of spurs on the apico-ventral end of hind tibiae. The last two can be easily distinguished from the others by several distinct features, but the separation of the first two from each other is problematic. A new species described here provided opportunity of re-evaluating their taxonomy. The new species Anterastes antecessor sp. n. is described based on morphology, male calling song and genetic data. The taxonomy of Anterastes and Koroglus is rectified based on phylogentic hypotheses obtained from representative 16S rDNA haplotypes. Sureyaella bella, Parapholidoptera signata and Bolua turkiyae are used as out groups in different combinations to obtain a more stable phylogeny. Although analyses with different outgroups suggested the same topology, the phylogenetic tree with outgroups Parapholidoptera signata and Bolua turkiyae resulted with the highest bootstrap supports to the branches. Phylogenetic trees suggested the following relationships for the ingroup species; (A. antecessor sp. n. + ((Koroglus disparalatus + A. uludaghensis) + (A. turcicus + (A. niger + (A. ucari + A. babadaghi))) + ((A. tolunayi + (A. serbicus + A. antitauricus + A. burri)))). Considering the phylogenetic hypotheses and characters used in previous publications, Koroglus is put in synonymy with Anterastes, and a new combination is suggested for the only species of the former Anterastes disparalatus comb. n. A short remark is given about the characters used in the generic taxonomy of the group.References
