Orthopelma
Orthopelma is a Holarctic genus of parasitoid wasps, the sole genus in the subfamily Orthopelmatinae (Ichneumonidae). Species are idiobiont endoparasitoids that develop within cynipid galls on Rosaceae, primarily attacking gall wasps in the genus Diplolepis on Rosa species. The genus contains 13 extant species distributed across the Nearctic and Palearctic regions.
Orthopelmatinae
Orthopelmatinae is a monogeneric subfamily of Ichneumonidae containing only the genus Orthopelma. Members are Holarctic idiobiont endoparasitoids specialized on cynipid gall wasps, primarily Diplolepis species on roses. The subfamily exhibits the rare egg-larval parasitoid strategy, with females ovipositing directly into host eggs.
