Paracypha

This monotypic genus (considered by some to be a synonym of Rhinocypha , e.g. Paulson et al. 2024) is represented by Paracypha unimaculata which is restricted to Meghahalya (Assam) and the Himalayas, ranging to Himachal Pradesh in the west. The larva was described but not figured by Laidlaw (1920); Kumar (1973) figures it in detail, and it is mentioned in the key of Kumar & Prasad (1977c). Its size separates it from most, but not all, sympatric chlorocyphid species, and the extensive spines along the lateral margin of the prementum may be a good generic character. Kumar (1973) illustrates uneven caudal spikes, suggesting one has regenerated, without detail, but a specimen in the collection of S.G. Butler suggests that the head shape and the spikes may also provide distinctive characters (S.G. Butler pers comm.).
