Description of the Mature Larva of Nemka viduata (Pallas) (Hymenoptera: Multillidae: Mutillinae), a Parasitoid of Stizus continuus (Klug) (Hymenoptera: Crabronidae: Bemibicinae)

The mature larva of Nemka viduata (Pallas) is described and illustrated. Morphological structures of phylogenetic value are discussed. The mature larva of this species is recognized by the followings traits: (a) head with parietal bands, (b) frontoclypeal suture distinct, and (c) labium with eight apical setae and two apical papillae. After further investigation, the presence of two apical papillae on the labium may represent an autapomorphy for the genus Nemka Lelej.
