About the Bent-Shielded Besieger Wasp

Gnamptopelta obsidianator is a species of wasp in the family Ichneumonidae and the only species in the monotypic genus Gnamptopelta. The genus name Gnamptopelta is derived from the Greek γναμπτός (gnamptós) meaning 'bent' or 'curved' plus the Greek πέλτη (péltē) meaning 'shield'. This refers to the concave shape of the clypeus found in this genus.

Gnamptopelta obsidianator can be distinguished from allied genera by the concave structure of the clypeus. They are large wasps with a body length of 20 to 23 millimetres (13⁄16 to 7⁄8 in). The scutellum is high and conical. Typically, the body is almost entirely black, including the wings, except for the fore and mid legs, of which the tibiae and tarsi are yellowish-brown. In some specimens, the orbits may be yellow. The antennae are orange-yellow, sometimes with the tips blackish. Specimens from the southern extent of the species' range may have parts of the head and thorax more or less ferruginous.

This species is very similar in appearance to Conocalma brullei but can be distinguished by the lack of an elevated structure on the petiole of the abdomen and by the shape of the clypeus.... Wikipedia →
