Abstract

Chromosomal analysis of more than 500 larval black flies from 19 sites in Armenia and Turkey revealed five taxa in the Prosimulium hirtipes group: Prosimulium frontatum Terteryan, Prosimulium rachiliense Djafarov cytoform 'A,' P. rachiliense Djafarov cytoform 'B,' Prosimulium tomosvaryi (Enderlein), and a new species of Prosimulium. To associate the names rufipes (Meigen) and tomosvaryi with cytological entities, larvae from the respective type localities in Germany were characterized chromosomally. Prosimulium frontatum is restricted to the Caucasus Mountains where studied populations have five unique inversions. It is most closely related to cytoforms 'A' and 'B' of P. rachiliense, the three taxa sharing one unique inversion. The two cytoforms of P. rachiliense are separated by about 1200 km, obscuring decisions about their reproductive isolation. The names rachiliense and possibly pronevitschae Rubtsov apply to cytoform 'A' in Armenia, whereas the name fulvipes (Edwards) might apply to cytoform 'B' in Turkey and to material formerly identified in Turkey as P. rufipes. Populations of P. tomosvaryi in Armenia are chromosomally distinct from previously studied populations in Europe and Morocco, although tied to European and Turkish populations by a shared X-linked inversion. We conservatively view Armenian, European, and Turkish populations of P. tomosvaryi as a single, polymorphic species. A new species, chromosomally related to P. hirtipes (Fries) and P. tomosvaryi by two uniquely shared inversions, was discovered in Turkey. (C) 2014 The Linnean Society of London
