The Acampsohelconinae are a subfamily of braconid parasitoid wasps. Extant members of this subfamily were previously included in the Helconinae, Blacinae, or Sigalphinae. The four genera included are †Acampsohelcon, Afrocampsis, Canalicephalus, and Urosigalphus.
Description and distribution
Acampsohelconinae are non-cyclostome braconids with a carapace covering the metasoma. The outer hind tarsal claws are modified and much larger than the midtarsal claws.
Canalicephalus has an Indo-Australian distribution, Afrocampsis has an Afrotropical distribution, and Urosigalphus is found mostly in the New World with one species found in Japan.
Biology
Hosts and habits of most Acampsohelconinae are unknown, but members of Urosigalphus are parasitoids of seed feeding beetle grubs in the Bruchidae and Curculionidae.
