Endopod with small first segment, lacking setae, second segment large, third and fourth segments smaller. I saw only a distal seta on the second segment, a distal seta on the third segment, and three apical setae on the fourth endopod segment, but there is a chance that the animal possessed more setae, which were lost. So, approximate antennal formula (0)-(Ḳ10)-(Ḳ6)-(Ḳ6)/(0)- (1?)-(1?)-(3?). No spines were found on any segments. Mandibles small.

Unfortunately, preservation of fossils from Chalunikha and Unda is weak compared to those from Ust’-Baley. I did not find any evidence of the presence of more than one species in each locality. Also, I did not find any differences between specimens from the two localities, so I placed cladocerans from Unda in the same species, although I did not include them in the
