Sigalphinae is a subfamily of braconid wasps, containing 8 genera and less than 50 described species.
Description 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.
All species with known hosts are koinobiont endoparasitoids which attack larval Lepidoptera from the families Noctuidae (most species) and Geometridae (Minanga patriciamadrigalae).
Genera The following are the currently accepted genera placed in Sigalphinae:
Acampsis Wesmael, 1835 Aposigalphus van Achterberg & Austin, 1992 Malasigalphus van Achterberg & Austin, 1992
Minanga Cameron, 1906 Notosigalphus van Achterberg & Austin, 1992 Paphanus van Achterberg & Riedel, 2009 Pselaphanus Szépligeti, 1902 Sigalphus Latreille, 1802
