First description and bionomic notes for the final-instar larva and pupa of an Oriental dobsonfly species, Neoneuromus sikkimmensis (van der Weele, 1907) (Megaloptera: Corydalidae)

Neoneuromus  van der Weele, 1909, a member of megalopteran subfamily Corydalinae, is a common and widespread dobsonfly genus of the Oriental Region. The adult taxonomy of  Neoneuromus  is relatively well-known but the larvae and pupae are undescribed. In this paper we describe the last-instar larva and the pupa of  N .  sikkimmensis  (van der Weele, 1907), representing the first detailed description of any immature stage of  Neoneuromus . Information on the bionomics of this species is also reported.
