Description:

Female.

Fully winged; length 2.81–3.37 mm (holotype 3.37 mm). Head black, with mandibles, clypeus, genae and anterior third or fourth of face whitish; antennae testaceous, with segments 7–10 slightly darkened; mesosoma black, with pronotal tubercles and part of lateral regions of pronotum whitish or testaceous; gaster brown; legs completely whitish. Antennae clavate; antennal segments of holotype in following proportions: 10:5:14:11:9.5:8:6.5:6:6:8. Head dull; face and vertex completely reticulate rugose or impressed with very large punctures; in a few paratypes face with a more or less large smooth and finely punctate area in front of anterior ocellus; temples reticulate rugose; frontal line complete; occipital carina complete; POL = 6; OL = 3.5; OOL = 9; OPL = 7; TL = 9; greatest diameter of posterior ocelli = 3. Scutum reticulate rugose, with posterior third or half strongly punctate and without sculpture among punctures. Notauli absent, or barely developed near anterior margin of scutum. Scutellum and metanotum punctate, without sculpture among punctures. Propodeum reticulate rugose, without transverse or longitudinal keels. Forewing partly hyaline and partly slightly darkened; distal part of stigmal vein longer than proximal part (14:9). Fore tarsal segments in following proportions: 15:4:4:12:15. Enlarged claw ( Fig. 1 ) with small subapical tooth, without bristles or hairs. Segment 5 of front tarsus ( Fig. 1 ) with 1 row of approximately 31 short and small lamellae; distal apex with group of about 5 small lamellae, in addition to 3 longer lamellae. Tibial spurs 1, 1, 2 .

Head black, with mandibles, clypeus, genae and anterior third of face whitish; antennae testaceous, with segments 7–10 slightly darkened; mesosoma black, with pronotal tubercles and part of lateral regions of pronotum whitish or testaceous; gaster brown; legs completely whitish. Antennae filiform; antennal segments in following proportions: 9:4:12.5:10:10.5:10.5:9:8:6.5:9. Head dull; face and vertex reticulate rugose, or impressed with very large punctures; in a few paratypes face with a more or less large smooth and punctate area in front of anterior ocellus; temples reticulate rugose; frontal line complete; occipital carina complete; POL = 6; OL = 4; OOL = 8.5; OPL = 7; TL = 10; greatest diameter of posterior ocelli = 3.

Scutellum and metanotum punctate, without sculpture among punctures. Propodeum reticulate rugose, without transverse or longitudinal keels. Forewing partly hyaline and partly slightly darkened; distal part of stigmal vein longer than proximal part (13:10). Genitalia in Fig. 2 . Tibial spurs 1, 1, 2.

Olmi det.2005 ^” (NMSA) . Paratypes: same data as holotype, 1^2ơ (NMSA), 1^1ơ (MOLC); KwaZulu-Natal: Pietermaritzburg, Karkloof Nat. Res. (East), Unit 4, 29 ° 19.1'S: 30 ° 15.5'E, alt. 1345 m, 22–24.iv.2005, yellow pan trap, V. Kolyada, 8^5ơ (NMSA); Pietermaritzburg, Ferncliff Nat.

Hosts: Unknown.

Comparison: The female and male of C. kolyadai differ from all other Afrotropical Conganteon in having whitish or testaceous lateral regions and posterior tubercles of the pronotum, whereas the latter is entirely black in the other species.
