Synonyms and other taxonomic changes

Based on a molecular phylogenetic analysis of subfamilial relationships within Braconidae, Sharanowski et al. (2011)(1) removed tribe Brachistini, in which Triaspis falls, from Helconinae, along with other former tribes of the former Helconinae, and placed them in a new subfamily (Brachistinae) along with Blacini (formerly Blacinae).

Numbers

About 100 New World species, many of these undescribed Neotropical species (2).

Size

about 1 mm

Identification

Metasomal segments 1 and 2 fused;

Metasoma carapace-like;

Outer claw and inner claw of hind leg equal in size;

Metasomal carapace either with 2 complete transverse grooves, or posterior groove incomplete, but at least present laterally;

Fore wings as pictured here.

Range

Cosmopolitan (2).

Food

Solitary endoparasitoids of larvae of beetles in families Curculionidae and Bruchidae (2).

Life Cycle

Egg-larval parasitoids (2).
