Abstract

Characteristics of cephalic structures and spiracles of final-instar larvae of three species of the genus Toxophoroides (Hymenoptera: Ichneumonidae: Lycorininae) are described and illustrated, and a key for their separation is given. As this is the first known information on larvae of the subfamily Lycorininae, characteristics of the group are defined, based only on the single genus studied.
