Remarks. After comparison material of H. plumatus (Dyachkov 2020; unpublished data) with the specimen of H. cf. plumatus (mentioned in Dyachkov 2019), we consider this specimen as H. plumatus . The main morphological characters of this specimen correspond well to the original description by Zalesskaja (1978), a sole difference is in 3+3 gonopodal spurs (2+2 according to the original description); it can be attributed to intraspecific variability.

H. plumatus is known from Kazakhstan, Kyrgyzstan, and Tajikistan only.
