Head brown, with mandibles, clypeus and short median median longitudinal frontal stripe near clypeus testaceous; antennae testaceous-darkened, with ventral side of segment 1 yellow; mesosoma brown, with scutum, metanotum and distal apex of propodeum testaceous-darkened; petiole black; gaster brown; legs brown, with tarsi and articulations testaceous-darkened. Head flat, dull, granulated; frontal line complete; occipital carina absent; POL = 1; OL = 1; OOL = 7; greatest diameter of posterior ocelli = 1. Antennae clavate; antennal segments in following proportions: 7:5:13:7:6:5.5:5:5:4:6. Maxillary palpi 6-segmented; labial palpi 3-segmented. Pronotum crossed by strong transverse impression, with dorsal surface shiny and without sculpture and lateral regions shiny and slightly granulated. Scutum slightly granulated, with 2 lateral points on sides of scutellum. Metanotum granulated, hollow behind scutellum. Metathorax + propodeum dull, with disc and anterior and posterior surface granulated; posterior surface not transversely striate (only with a few transverse striae at posterior extremity). Mesopleura and metapleura granulated, not transversely striate. Mesometapleural suture distinct and complete. Fore tarsal segments in following proportions: 12:2:5:16:24. Enlarged claw ( Fig. 29 ) with small subapical tooth and 3 proximal hairs. Segment 5 of front tarsus ( Fig. 29 ) with 2 rows of 3 (proximal) + 22 lamellae; distal apex with group of 9 lamellae.

Holotype: ^“ SOUTH AFRICA: KwaZulu-Natal, Pietermaritzburg, Hilton [29º32'30.7"S: 30º18'18.4"E, alt. 1131 m], 19–21.iv.2005, yellow pan trap, V. Kolyada ”; [red] “ Gonatopus kolyadai sp. n. 2005, ^” (NMSA).

Hosts: Unknown.

Comparison: G. kolyadai belongs to the G. incognitus group. The female is similar to those of G. patrizii Benoit, 1951 , G. aestivus Olmi, 1987 , and G. turneri (Benoit, 1951) , but it may be distinguished by the flat head (head excavated in the other three species) and the completely granulated metathorax + propodeum (metathorax + propodeum with a different sculpture in the other three species).
