RESUMO

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.

RESUMO

We examined phylogenetic relationships in two lineages of Leuciscinae cyprinid fishes based on the sequence data of the complete mitochondrial DNA region coding for the cytochrome b gene (1140 bp). Telestes includes obligate riverine, moderately cold water-adapted species whereas Scardinius comprises warm-adapted species living in lowland lakes and still waters of rivers and streams. We also analysed selected representatives of Leuciscus and Phoxinellus because the taxonomic status of some species belonging to these genera is dubious and they could be placed in the genus Telestes. The study includes 18 species, 43 populations, and 111 individuals from 9 of the 14 peri-Mediterranean ichthyogeographic districts. Clades recovered from the phylogenetic analyses do not support previous taxonomic assumptions based on morphology. Telestes, Leuciscus, and Phoxinellus do not form monophyletic assemblages; phylogenetic analyses suggest that L. polylepis, L. turskyi, P. croaticus, and P. metohiensis should be included in Telestes. Similarly, populations of Scardinius erythrophthalmus do not cluster together and the endangered S. scardafa, endemic to central Italy and surviving in a single locality, is nested within them. The radiations of Telestes and Scardinius occurred in different time periods. A major diversification of Telestes is consistent with a sea dispersal during the freshwater Messinian "Lago Mare" phase of the Mediterranean Sea. Cladogenetic events within Scardinius are likely related to the extension and confluence of river drainages in lowlands following multiple lowering of the sea level during the Quaternary glaciations.
