The Cephalic Structures and Spiracles of Final-Instar Larvae of the Subfamily Campopleginae, Tribe Campoplegini (Hymenoptera: Ichneumonidae)

Characteristics of the cocoons, cephalic structures, spiracles, and skins of 97 species and 19 genera of the tribe Campoplegini (Hymenoptera: Ichneumonidae: Campopleginae) are described and illustrated and keys are given for identification of the genera and species. An additional five species and two genera that were described and illustrated in earlier papers (Finlayson 1967, 1969) are included in the keys, for a total of 102 species and 21 genera. Characteristics of final-instar larvae were found that support most of the generic entities defined on the basis of adult characteristics, and new relationships were revealed that may assist with taxonomic problems in the group.
