Acampsohelconinae

Genus Guides

1

Acampsohelconinae is a of braconid characterized by a metasomal and modified hind tarsal claws. The subfamily contains four : the extinct †Acampsohelcon and three extant genera—Afrocampsis, Canalicephalus, and Urosigalphus. These wasps were historically classified within Helconinae, Blacinae, or Sigalphinae before their current subfamily status was established. associations are poorly documented except for Urosigalphus, which parasitizes seed-feeding larvae.

Identification

The combination of a metasomal and enlarged, modified outer hind tarsal claws separates Acampsohelconinae from other braconid . Canalicephalus is further distinguished by its Indo-Australian distribution, Afrocampsis by its Afrotropical range, and Urosigalphus by its primarily New World distribution with one Japanese .

Appearance

Non-cyclostome braconids with a hardened covering the metasoma. The outer hind tarsal claws are conspicuously modified, appearing much larger than the midtarsal claws. These morphological traits distinguish them from related .

Distribution

Afrocampsis occurs in the Afrotropical region. Canalicephalus has an Indo-Australian distribution. Urosigalphus is found primarily in the New World, with a single recorded from Japan. The extinct †Acampsohelcon has no specified distribution.

Diet

Members of Urosigalphus are of seed-feeding in Bruchidae and Curculionidae. associations for Afrocampsis and Canalicephalus are unknown.

Host Associations

Ecological Role

contributing to of seed-feeding beetles, based on known Urosigalphus .
