ABSTRACT

The last instar larva of Microstigmus nigrophthalmus Melo, 1992 is described. It markedly differs from that of M. comes Krombein, 1967 the only other species in the genus whose mature larva have been described, for features as follows: presence of spinnerets; setae on the labrum, maxillae and labium; mandibles with tridentate apex and a bidentate lateral projection; lack of the conical supranal processo Notes on habitat, structure, and content of nests are also presented.

Key words: Microstigmus nigrophthalmus, sphecoid wasp, morphology, larva, biology, behaviour, Brazil
