ETYMOLOGY: The species is named after the
type
locality.
DIAGNOSIS: Males of
H. zombaensis
are recognized by the forwarddirected RTA with two sharp, opposed prongs, one pointing up, the other one down. Females can be recognized by the second part of the ID making a ventrally oriented Uloop and describing a complete corkscrew turn before entering ST1.
MALE:
Measurements.
Total length 1.86; carapace 0.84 long, 0.65 wide; length of fe: I 0.68, II 0.70, III 0.57, IV 0.81.
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. licerae and legs yellow, sternum light yellow. Abdomen peach, no pattern.
Palp.
RTA a ventrolateral swelling, directed obliquely forward, extremity with two prongs, the external one pointing up, inferior one much short er, pointing down; cymbium fairly elongate, without retrolateral concavity or series of long curved setae; sperm duct fairly narrow over entire course, slightly more narrowed toward embolus, with deep turn before entering oval swelling at base of embolus; MA originating in center of tegulum, with fairly narrow, transverse base, sharply curved backward and broadened, ending in evenly curved, gradually tapered distal part, pointing forward; embolus originating on posterior part of tegulum, whiplike, looped over slightly less than 360° (fig. 17n, o).
FEMALE:
Measurements.
Total length 2.30; carapace 0.95 long, 0.73 wide; length of fe: I 0.73, II 0.78, III?, IV 0.86.
Leg spination.
Fe: I rv 2; IV plt 0 rlt 0; ti: I, II vsp 6; mt: III plt? vt? rlt?; IV plt 1 vt 1 rlt 1.
Coloration.
Carapace orange with eight brown radial striae, lighter at the fovea. Chelicerae, sternum, and legs yellow. Abdomen peach, no pattern.
Genitalia.
Vulva: first stretches of IDs fused into one weakly sclerotized entrance chamber with entrance toward posterior side. Anterior end of this weakly sclerotized part split in two more heavily sclerotized, outwardpointing tips connected to second part of ID, which has sclerotized wall. The second part of ID first makes ventrally oriented Uloop and then runs in posterior direction, describing a complete corskscrew turn before entering the small, elongate ST1; a subglobular, stalked ST2 attached to ID at transition between thinwalled and sclerotized part (figs.
17m
; 20b).
