Helicorbis kozhovi Starobogatov et Streletzkaja, 1967

( Table 6; fig. 7 G)

Regional distribution. VinarSki (2015b) recorded Helicorbis kozhovi from two localitieS in EaStern Mongolia and proVided a map of all habitatS of the SpecieS known to the date. In addition to theSe localitieS, we found H. kozhovi in ZhaltSanoVa’S collection, in a Sample labeled aS “ 18.06.1983 Tuulyn TSoorom” (poSSibly, a waterbody belonging to the Tuul-Gol RiVer).

Extra-limital distribution. ThiS SpecieS waS conSidered endemic to EaStern Siberia ; recently it waS found in the eaSternmoSt partS of WeStern Siberia ( VinarSki 2015b).

Morphology. SpecimenS of H. kozhovi collected in Mongolia are morphologically identical to indiVidualS of thiS SpecieS from Siberia deScribed by StarobogatoV & Streletzkaja (1967) and VinarSki (2015b).
