Active tectonic history of the Eastern Mediterranean, especially around Aegean area, through the Neogene led to interesting radiation patterns of animal lineages, allowing intriguing biogeographical hypotheses to be tested. Descendants of the ancestral stock in the Miocene Aegean Plate presently occur in the Anatolia, Aegean islands and the Balkan Penninsula. Troglophilus (Orthoptera, Rhaphidophoridae, Troglophilinae) is such a genus represented in these areas with approximately 15 species. The present study addresses the phylogeography of the genus, with a special emphasis on its Anatolian members, aiming to test the biogeographical patterns suggested for this area using mitochondrial [cytochome oxidase I (COI)] and nuclear (ITS1‐5.8S–ITS2) markers. Data matrices obtained from sequences of COI and ITS1‐5.8S–ITS2 were used for phylogenetic analyses using Dolichopoda lycia and Dolichopoda sbordonii as outgroups. All sets of the analyses suggested monophyly of the Anatolian haplotypes, although they are not congruent in revealing their relationships. Anatolian haplotypes constituted three main phylogroups in trees calculated from a matrix of short COI sequences: the ECMA (corresponding to the Eastern part of coastal Mediterranean Anatolia); the CWMA (from the Central and Western part of Mediterranean Anatolia); and NA (from Northern Anatolia). Trees obtained using longer sequences resulted in only two phylogroups, namely ECMA and CWMA + NA. The trees based on the ITS1‐5.8S–ITS2 data matrix supported monophyly of Anatolian phylogroups. BEAST analysis of the COI estimated the time to most recent common ancestor for Dolichopoda and Troglophilus as 10.8 Mya, to that for the Anatolian + Balkan Troglophilus as 7.2 Mya, and to that for the Anatolian Troglophilus as 6.3 Mya. BEAST analysis of ITS1–ITS2 intron regions is largely congruent with that of COI. From these results, several conclusions were drawn. First, the divergence of Dolichopoda and Troglophilus possibly started with the opening of the Mid‐Aegean Trench in the Tortonian. Second, Troglophilus possibly originated from an ancestral stock in the old Aegean Plate. It later diverged as Anatolian and Balkan lineages and, possibly, the Cretan population may be regarded the third lineage. Divergence within the Anatolian lineage is estimated to have occurred through the Pliocene and Pleistocene, although before the last four glacial periods in the late Pleistocene. Additionally, the northern Anatolian Troglophilus appears to originate from the dispersal of an ancestral stock from a mountainous lineage through the Taurus Way. © 2012 The Linnean Society of London, Biological Journal of the Linnean Society, 2012, 108, 335–348.

“…The genus Troglophilus is represented by a remarkably smaller number of species with a disjunct distribution in the eastern part of the Mediterranean. According to present knowledge 14 valid species from this genus have been described (Karaman, 1958; Kollaros, Paragamian & Legakis, 1991; Heller et al ., 1998; Rampini & Di Russo, 2003; Di Russo, Rampini & Landeck, 2007). Two centres of species richness emerged (Fig.…”

We present a revision of the genus Troglophilus in the western part of the Balkan Peninsula based on morphological and genetic analysis, and provide distribution data for the species. The results of these analyses reduced the number of the known taxa within the genus Troglophilus in this area to five valid species: Troglophilus cavicola (Kollar, 1833), Troglophilus neglectus Krauss, 1879, Troglophilus ovuliformis Karny, 1907, Troglophilus brevicauda Chopard, 1934, and Troglophilus lazaropolensis Karaman, 1958. A new species Troglophilus zorae sp. nov. is described and Troglophilus neglectus serbicus Maran, 1958, Troglophilus neglectus vlasinensis Maran, 1958, Troglophilus bukoviki Karaman, 1968 and Troglophilus pretneri Us, 1970 are synonymized. The distribution pattern of the western Balkan species supports a general east-west migration route. We also determined the centres of origin and spreading directions of particular species according to the distribution of the taxa and the structure of the haplotypes.

Troglophilus neglectus (Gryllacridoidea, Raphidophoridae) is a nocturnal Ensifera which can be found in caves of Slovenia. The anatomy of the tibial organs in the fore-, mid-, and hindlegs, as well as the external morphology of the proximal fore-tibia and the prothoracic tracheal system, is described comparatively. In the prothorax and in the forelegs, no sound-conducting structures such as an acoustic trachea, enlarged spiracles, or tympana are developed. A group of 8-10 campaniform sensillae is located in the dorsal cuticle of the proximal tibia. In each leg, the tibial organ complex is built up by two scolopale organs, the subgenual organ and the intermediate organ; the structure and the number of scolopidia is similar in each leg. No structure resembling the crista acoustica is found. The subgenual organ contains around 30 scolopidia; the intermediate organ is subdivided into a proximal part containing 8-9 scolopidia and a distal part with 5-6 scolopidia. The two groups of scolopidia are not directly connected to the tracheal system. The tibial organs in the forelegs are insensitive to airborne sound, and they appear to be more primitive compared to those found in members of the Tettigoniidae and the Gwllidae. The results indicate that the complex tibial organs in all legs of T. neglectus are primarily vibrosensitive. © 1995 Wiley-Liss, Inc.
