Small hymenopteran insects , length from 2.5 to 4.0 mm. Brown (legs lighter); brown scapus ; legs are bicolor (yellow and brown). Flagellum brown with white 3-5th flagellomeres (consists of 21-26 segments). The head is mainly granular (forehead, face, vertex). Mesoscutum, scutellum and mesopleuron are smooth. The distance between the compound eye and the simple eye (ocellium) is more than 2.5 times the diameter of the lateral simple eye. Malar space is 0.25 times larger than eye height. First tergite of abdomen longitudinally furrowed. 4th-6th tergites are smooth. Vein r of fore wing equal to 75% of vein 3RSa. In the front wing, a radio-medial vein is developed. Fore tibia with single row of short spines along anterior margin. On the hind coxae of the legs there is a distinct anteroventral basal protrusion; the vertex of the head on the side of the eye is not sharp angular. Presumably, like other species of the genus Heterospilus , parasitize on beetles or butterflies. The species was first described in 2013 by the American hymenopterologist Paul Marsh ( Paul M. Marsh ; , Kansas , USA ) with a group of American fellow entomologists ( Wild Alexander L. , Whitfield James B .; University of Illinois at Urban- Champaign , Erbana , Illinois , USA) and is named after William Eberhard, who collected part of the model series. It differs from closely related species in smooth lobes of the mesoscutum and two distinct longitudinal carinae in front of the precutellar groove [1] .
