(Figs. 16A–E, 17A–B, 39C–D)
Type series: Holotype female, dissected and slide mounted, South Africa, DC 85 84 Eastern Transvaal, Houtbosloop on Rt 539 at “dinosaur park” S of Sabie, 20 m wide – sand and rocks, 11˚C, 27.v.1984 Cook. Paratypes: same data as holotype, 0/2/0 (slide mounted).
Further records: South Africa, DC 76 84, Eastern Transvaal, Sterkspruit on Rt. 539 at border between Nelspruit & Belfast districts, 5–10 m wide, swift-clear-rocks, coll. in area of detritus, 12 ˚C, 23.v.1984 Cook, 2/1/0 (slide mounted).
Diagnosis: Dorsal shield oval (L/W ratio 1.1), with medial depression; muscle scars with moderately pronounced thickenings, extending to the edges of medial depression (39C–D); gnathosomal bay Y-shaped; tips of Cx-I slightly posterior to frontal margin. Palp (Figs. 16C, 17B): P-1 with a dorsal seta; P-2 with slightly concave ventral and strongly convex dorsal margins; P-3 ventral margin with basal inflation, from there to distal edge straight, equally narrow; P-4 slender, ventral margin slightly concave. Legs: I-L (Fig. 16D) with I-L-6 L/H ratio 2.7–3.0, ventral margin convex; IV-L: Fig. 16E; swimming setae numbers: III-L-4, 3-4; III-L-5, 5; IV-L-4, 4-5; IV- L-5, 4.

Discussion: Similar to Djeboa granatica sp. nov. from Madagascar (see there for further discussion).
Distribution: South Africa; known only from the type locality.
