ETYMOLOGY: The species is named in hon­ or of Dr. Ansie Dippenaar­Schoeman.

DIAGNOSIS: Males of H. schoemanae are recognized by the RTA with two tips pointing upward. Males are similar to those of H. coccinatus from which they differ by the simple MA. Females can be recognized by the inward­curling anterior ends of the deeply bifurcated entrance chamber of the vulva in combination with the rather large, globular ST2 touching each other on the symmetry axis.

MALE: Measurements. Total length 1.57; carapace 0.73 long, 0.59 wide; length of fe: I 0.59, II 0.62, III 0.51, IV 0.78. Leg spination. Fe: I rv 2; IV plt 0 rlt 0; ti: I, II vsp 5; mt: III plt 0 vt 0 rlt 0; IV plt 0 vt 1 rlt 0. Coloration. Carapace, legs, chelicerae, and sternum orange yellow. Abdomen pale pink, no pattern, sparsely covered with thin, point­ ed grey setae. Palp. RTA extended downward; extremity with ventral boss and two dorsal tips pointing upward; cymbium fairly

wide basal part and hardly narrower distal part with deep turn in front of embolus; MA attached in center of tegulum, simple, with fairly narrow base, gradually tapered from to sharp tip; embolus originating on posterior part of tegulum, with fairly broad base, long, whiplike, looped over slightly less than 360° (fig. 15n, o).

FEMALE: Measurements. Total length 2.24; carapace 0.86 long, 0.73 wide; length of fe: I 0.73, II 0.76, III 0.59, IV 0.89. Leg spination. Fe: I rv 2; IV plt 0 rlt 0; ti: I, II vsp 6; mt: III plt 0 vt 0 rlt 0; IV plt 0 vt 1 rlt 0. Coloration. Carapace, legs, chelicerae and sternum orange yellow. Abdomen pale pink, no pattern, sparsely covered with thin, pointed grey setae. Genitalia. Vulva: first stretches of IDs fused into one weakly sclerotized, deeply bifurcated entrance chamber with entrance toward posterior side. Long anterior ends of this weakly sclerotized part graciously curved inward and merging into two more heavily sclerotized, inward­pointing tips attached to the sessile, subglobular ST2. End of inward­pointing sclerotized tip of entrance chamber connected to second, normally sclerotized part of ID running in posterior direction, which makes outward Uloop and a complete corkscrew turn before connecting to the small, globular ST1 (figs. 15m; 18c).

DISTRIBUTION: From Sabie to Piggs Peak, East Transvaal, South Africa.
