New Euscorpius species from Southern Bulgaria

The scorpion fauna in Bulgaria is under investigation and in a recent paper Tropea and co-workers present a new species in the genus Euscorpius Thorell, 1876 (Euscorpiidae) from the Western Rhodope Mts. in southern Bulgaria.

A special combination of characters has not made it possible to assign the new species to any of the established subgenera.

A new scorpion species, Euscorpius drenskii sp. nov., is described from the Western Rhodope Mts. in southern Bulgaria. It is characterized by an oligotrichous trichobothrial pattern, which shows a conspicuous loss of one trichobothrium in the external median patellar series (em = 3), also observed in E. carpathicus (Linnaeus, 1767) and the subgenus Alpiscorpius Gantenbein, Fet, Largiadèr & Scholl, 1999. Phylogenetic analysis of 16S rDNA marker sequences does not show any close relationship between these three groups, suggesting that the observed loss of a trichobothrium is an independent event.

Thanks to professor Victor Fet and Gioele Tropea for sending me the new article!
