Hercostomus vodjanovi Negrobov, Maslova et Selivanova, 2016

Hercostomus vodjanovi Negrobov, Maslova, Selivanova, 2016: 175 .

Notes. The species has been recently described by single holotype collected from the southern slope of Gissar Range at about 20 km from the country capital Dushanbe. Hercostomus vodjanovi description and illustrations correspond to the morphology of H. exarticulatoides types examined. However, a small ventral tubercle at base of male mid femur was not found by authors [ Negrobov et al., 2016], (O.P. Negrobov, personal communication, 2019). We think that this character has been overlooked, and the species is a possible synonym to H. exarticulatoides .

Distribution. Type locality: Tajikistan, Gissar Range, historical nature park Shirkent. Palaearctic: Tajikistan.
