The larval stage of the Himalayan Neallogaster hermionae (Fraser) (Anisoptera: Cordulegasteridae)

The ultimate instar larva of both sexes is described and illustrated on the basis of material from Kameng (Assam, India) and Khumbu Himal (Nepal). Some field notes are provided, and 2 penultimate instar larvae from the Siwapuri Dara (Nepal) are brought on record. The larval characters of Neallogaster do not differ significantly from the typical cordulegasterid features, but they are essentially different from the Chlorogomphinae. Considering the close relationship between Cordulegaster, Anotogaster and Neallogasler. it is suggested that the Himalayan region may represent the centre of this group of genera.
