Within the subgenus Nevermannia, this species is assigned to the vernum-group by the combination of the following characters: male genitalia with a lamellate ventral plate without median keel, an elongate style with a large, broad, inwardly-twisted apex, a single parameral hook per side, and an inverted Y-shaped median sclerite; pupal gill with four slender filaments per side; and larval mandible with supernumerary serrations. Interestingly, this species has the katepisternum haired in both sexes of adults, female genital fork with a prominent projection directed forwards on each arm, and pupal frons with two trichomes on each side, all of which are rare in this species-group.
