Sigalphinae is a subfamily of braconid wasps, [1] containing 8 genera and less than 50 described species. [2]
Species in the subfamily Sigalphinae are rare but have a worldwide distribution. They can be distinguished from other subfamilies of Braconidae by the combination of the hindwing with vein CUb present, the forewing with vein M + CU tubular and second submarginal cell longer than wide, the petiole with a pair of longitudinal carinae, and a metasoma that is not laterally compressed. [1]
All species with known hosts are koinobiont endoparasitoids which attack larval Lepidoptera from the families Noctuidae (most species) and Geometridae ( Minanga patriciamadrigalae ). [2]
The following are the currently accepted genera placed in Sigalphinae: [2]
