03C088714E1DFFE6FDFDFEC0FB23A28D.taxon	diagnosis	Diagnosis Having simple fore tarsus, the new species is close to H. nectarophagus Curran, 1924, differing distinctly in male mid and hind femora each with ventral row of erect cilia, about as long as diameter of femur. Hercostomus nectarophagus males have no long ventral cilia on femora (Grichanov 1999). The hypopygia are rather species-specific in the two species.	en	Grichanov, Igor Ya.

03C088714E16FFEEFD97F94AFB53A5BC.taxon	diagnosis	Diagnosis The new species is sister species to H. sanipass sp. nov., differing distinctly in its smaller size, narrower face, lighter colored legs, weakly widened fore tarsomere 3. The hypopygia are rather similar in the two species. Nevertheless, the proximal arm at apex of ventral lobe of postgonite in H. koshelevae sp. nov. is always thinner than that in H. sanipass. The long basolateral cercal lobe in males of both species is very peculiar, being much shorter in males of close species with modified fore tarsus.	en	Grichanov, Igor Ya.
