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 After comparison material of H. plumatus (Dyachkov 2020; unpublished data) with the specimen of H. cf.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.
