Dinarippiger gen. nov. (Tettigoniidae: Bradyporinae: Ephippigerini), a new saddle bush-cricket genus for Ephippiger discoidalis Fieber, 1853 from the Dinaric karst.

A new genus of the tribe Ephippigerini, Dinarippiger Skejo, Kasalo, Fontana et Tvrtkovic gen. nov., is described based on the characters of occiput coloration, tegmina coloration, cerci and pronotum shape. The new genus is morphologically intermediate between the genera Ephippiger Berthold, 1827 and Uromenus Bolívar, 1878, and presently includes only Dalmatian Saddle Bush Cricket, Dinarippiger discoidalis (Fieber, 1853) comb. nov., hitherto known as Ephippiger discoidalis Fieber, 1853. The species inhabits NE Italy (mainly Carso Triestino), SW Slovenia, Croatia, Bosnia & Herzegovina, and Montenegro, i.e., islands and karst habitats along the eastern Adriatic coast, with isolated findings in Albania and Italy. Its prominent variation in size and coloration has already produced many synonyms (= limbata Fischer, 1853, = limbata var. major Krauss, 1879, = limbata var. minor Krauss, 1879, = selenophora Fieber, 1853, = sphacophila Krauss, 1879), which may suggest that what is currently regarded as a single species could represent a complex of distinct species with restricted distributions. This study also presents an annotated distribution map and a bioacoustic analysis of D. discoidalis comb. nov. Further research, especially adopting molecular methods, is necessary to assess possible cryptic diversity within the genus Dinarippiger gen. nov. and elucidate its evolutionary history.

Review of the Poecilimon (Poecilimon) zonatus species group and description of new species from Turkey with data on bioacoustics and morphology (Orthoptera: Phaneropterinae).

The aim of this study is to conduct a detailed taxonomic revision of the Poecilimon (Poecilimon) zonatus species-group (Orthoptera: Phaneropterinae) using both morphology and bioacoustics. Two new species (Poecilimon (Poecilimon) salmani, P. (P) azizsancar) and one new subspecies (P. (P) zonatus datca) are described. Based on the data, we conclude that the species complex can be separated into two subgroups (P. tauricola and P. zonatus). Within the P. zonatus subgroup, song structures indicate P. variicercis as basal branch since producing two syllable types is possibly a derived character. From both, from bioacoustics and morphology, it is concluded that the relationships between species of the group are as follows: P. tauricola subgroup (P. tauricola + P. azizsancar) + P. zonatus subgroup (P. variicercis + (P. varicornis + (P. zonatus zonatus+P. zonatus datca)) + (P. salmani+P. vodnensis)))). Except for two species (P. vodnensis and P. varicornis), the other species of the group are all distributed in Anatolia. P. vodnensis is known only from Macedonia, whereas, P. varicornis has been recorded only from Syria and Lebanon. We assume that the group originated from an Anatolian ancestral stock and expanded its distribution to the Balkans through Taurus Way and Dardanelles. Other ancestral populations may have also spread in the north-south directions through the appropriate steppe corridors in the Anatolian Diagonal Mountains and in its vicinity.
