“…Prosimulium petrosum and European Prosimulium latimucro , therefore, are homosequential species—they have the same fixed banding sequence but differ morphologically, a phenomenon first discovered in Drosophila (Carson et al 1967). Although not common in the Simuliidae, previous examples of homosequential species include several members of the Simulium vernum group (Hunter 1987, Adler et al 2004, Seitz and Adler 2015). …”

The karyotype of Armenian populations of the black fly Prosimulium petrosum Rubtsov, 1955 was characterized and compared with that of all other chromosomally known Palearctic members of the Prosimulium hirtipes group. Analysis of the polytene chromosomes established that Prosimulium petrosum is most closely related to European populations of Prosimulium latimucro (Enderlein, 1925) with which it shares an identical fixed chromosomal banding sequence. Its validity as a species, separate from Prosimulium latimucro, is based on its unique sex-differential sections in the expanded centromere region of chromosome I, in agreement with the unique structural configuration of the hypostomal teeth of its larvae. Prosimulium petrosum and Prosimulium latimucro, therefore, are homosequential species, demonstrating the value of a combined chromosomal and morphological approach in determining species status.
