Etymology: This species is named after the type locality, Western Cape.

Description:

Female.

Micropterous; forewing very reduced, reaching transverse furrow behind metanotum, slightly longer than scutellum (6:5). Length 3.18–4.25 mm (holotype 3.43 mm). Holotype testaceous, with antennal segments 8–10, ocellar area, prosternum, lateral regions of pronotum, posterior half of gaster darkened; scutum, metanotum, transverse furrow behind metanotum, posterior half of propodeum and petiole black; mesopleura and metapleura partly darkened; legs testaceous, with mid and hind coxae and clubs of hind femora darkened. Two paratypes from Kogelberg Nat. Res. broadly darkened or black, as follows: head testaceous, with ocellar region darkened; mesosoma black, with propleura, disc of pronotum, posterior collar of pronotum, scutellum, part of mesopleura testaceous; gaster partly testaceous and partly darkened or brown. Antennae clavate; antennal segments of holotype in following proportions: 7:5:15:11:10:8:7.5:7:6:9.5; antennal segments of a paratype in following proportions: 7:3:12.5:9:7:7:6:6:5:6.5. Head shiny, smooth, slightly granulated; occipital carina complete; frontal line absent; face with slender longitudinal furrow from anterior ocellus to clypeus; anterior region of face with tuft of long hairs. Head of holotype with POL = 2; OL = 3; OOL = 8.5; OPL = 5; TL = 10; greatest diameter of posterior ocelli = 2. Head of a paratype with POL = 2; OL = 2; OOL = 7; OPL = 4.5; TL = 9; greatest diameter of posterior ocelli = 1.5. Pronotum shiny, smooth, without sculpture, not crossed by transverse impressions, with short anterior collar; pronotal tubercles reaching tegulae. Scutum very reduced, rugose. Scutellum and metanotum shiny, smooth, without sculpture. Propodeum dull, with strong anterior transverse and rugose furrow situated behind metanotum; anterior surface of propodeum smooth, granulated; posterior surface of propodeum reticulate rugose. Mesopleura and metapleura granulated, dull, with a few transverse keels. Mesometapleural suture distinct and complete. Mesopleura with tufts of long hairs situated on sides of transverse furrow behind metanotum. Fore tarsal segments of holotype in following proportions: 10:2:5:13:22. Fore tarsal segments of a paratype in following proportions: 9:2:4:10:17. Chela ( Fig. 5 ) without rudimentary claw. Enlarged claw ( Fig. 5 ) with 2 peg-like lamellae situated further distally than proximal prominence. Segment 5 of front tarsus ( Fig. 5 ) with 2 rows of about 23–32 lamellae (32 in holotype); distal apex with group of 4 lamellae, among which one very long. Tibial spurs 1, 1, 2. Male. Unknown.

Holotype: ^“ SOUTH AFRICA: Western Cape, Walker Bay Nat. Res., 34 ° 27.41'S: 19 ° 21.39'E, 29.xi– 26.xii.1997, yellow pan trap, S. van Noort & B. Fisher ”; [red] “ Deinodryinus capensis sp. n. M. Olmi det. 2005 ^” (SAMC).

Paratypes: SOUTH AFRICA: Western Cape: Kogelberg Nat. Res., 34 ° 15'S: 19 ° 05'E, 16.xii.1999 – 16.i.2000, pitfall trap, S. van Noort, 1^(SAMC); same locality label, 16.iv.1999, S. van Noort, 1^(MOLC) .

Hosts: Unknown.

Comparison: The female of D. capensis is similar to that of D. paulyi , but the anterior surface of the propodeum is granulated (by contrast, in D. paulyi this surface is reticulate rugose).
