Remarks. This species is very similar to H. pulchra, however, both of these species can be distinguished by the following characteristics: uropodal endopod overreaches the exopod, and the telson without narrow medial portion, but steadily narrows towards the apex in H. parva; the uropodal endopod in H. pulchra is as long as or slightly shorter than the exopod and the concave border forms a waist-like or narrow medial portion at the telson (Biju & Panampunnayil 2011).
