Description

Hobbya stenonotus is a hyperparasitoid of Torymus cingulatus,^[1] which itself is a parasitoid of various species of gall wasps (Cynipidae).^[2]

The species is identifiable from other similar Pteromalidae by the deep excision on the clypeus, striation reaching from the clypeus to the base of the antennae, and by the length of the forewing's marginal vein which is around twice as long as the stigmal vein.^[3]
