In terms of morphology, this species shares close similarities with the Indian species H. pulcher. In males, it is characterized by a prominent, spinulose knob on the inner margin of the right basis, a finely serrated inner margin of the right second exopodite-segment, and an exceptionally large, tongue-like projection on the proximal inner margin of the left basis. In females, the genital somite is notably elongated, much longer than the combined length of the other two urosomites. Typically, it is found alongside 1–5 other diaptomids, with the most commonly co-occurring species being Neodiaptomus blachei.
