Abstract
A description of four new species of Dolichopoda Bolivar, 1880 (Orthoptera, Rhaphidophoridae) from Eastern Aegean region (Southern Sporades), including Western Turkey, is reported. This brings to a total of 11 the number of Dolichopoda species recorded for caves of the Aegean area. Overall, these species show a high degree of morphological homogeneity and they are very close to Dolichopoda paraskevi Boudou-Saltet, 1973 from Crete and Dolichopoda naxia Boudou-Saltet, 1972 from Cyclades (Naxos Island). The Western Turkish species are morphologically not closely related to the other Anatolian species; this suggests an independent origin for the taxa occurring in the Southern Taurus and Black Sea regions. These new data help to better define the already high level of diversity of the Hellenic Dolichopoda and strengthen the hypothesis that the central area of dispersal for the genus would correspond to the ancient Aegean plate.
Highlights
The subfamily Dolichopodainae Brunner von Wattenwyl, 1888 (Orthoptera, Rhaphidophoridae) is limited to the Northern hemisphere; several species belonging to the genus Dolichopoda Bolivar, 1880 inhabit caves of Southern Europe and Asia Minor
We describe three new species belonging to the cave cricket genus Dolichopoda from the Aegean Greek Islands (Southern Sporades) and one from the Western Turkish coast
The new species are all morphologically homogeneous, due to a strong similarity of most of the characters examined. Based on these characters the new species show a clear affinity with D. naxia from the Cyclades and with D. paraskevi from Crete
Summary
The subfamily Dolichopodainae Brunner von Wattenwyl, 1888 (Orthoptera, Rhaphidophoridae) is limited to the Northern hemisphere; several species belonging to the genus Dolichopoda Bolivar, 1880 inhabit caves of Southern Europe and Asia Minor. Keywords Cave crickets, Dolichopoda, new species, Eastern Aegean, Western Turkey This allowed us to describe four new Dolichopoda species from the Eastern Agean: two from caves on Samos, one on Kalymnos and one from the Aegean Turkey (İzmir and Aydın Province).
