Halozetes capensis Coetzee & Marshall, 2003

Adult

Measurements: Adult body size: Kommetjie: holotype (female) length 637, width 351 (the scale bar in the drawing of the original description ( Coetzee & Marshall 2003) is correct, but the sizes given in the text are incorrect and are rectified here), paratypes: female (n=1): length 662, width 374, males (n=4) length 565-595 (585), width 292-327 (314); Nature’s Valley: females

(n=2) length 590-617 (604), width 326-339 (333), males (n=3) length 571-586 (580), width

300-321 (311).

Integument ( Figure 12 ): dark brown in colour; leg tarsi, tibiae lighter brown; dorsal side distinctly granulate with various sized granules, on prodorsum granules medially from anterior to posterior along hour-glass shape of ro, le and in, ventrally small area of granules between leg I and II, remainder of ventral side without granulation, legs with granules of various sizes; chelicera punctate.

Prodorsum ( Figures 12A, D ): rostrum rounded in dorsal view, slightly projected in lateral view; ro (20-31) smooth, le (35-69) roughened, in very long (150-181), roughened, directed upwards, ex short (8-13), smooth; bothridium cup-like with small opening for bs ; bs with short stalk and clavate head (34-39).

Gnathosoma ( Figure 12C ): palp similar to that of H. belgicae mickii ( Coetzee 2000) , palp setation 0-2-1-3-9+1ω, palp solenidion ω and eupathidium acm connected, forming double horn; cheliceral setae setiform, barbed, chb slightly shorter than cha.

Notogaster ( Figures 12A, D ): elongated oval in dorsal view; anterior margin projecting anteriorly, dorsosejugal furrow medially indistinct; 14 pairs of smooth, stout notogastral setae (c 1-2, da, dm, dp, la, lm, lp, h 1-3, p 1-3), c 3 absent, ranges in the lengths of the dorsal setae on the notogaster quite large within populations, in the holotype the lengths towards the lower ranges

(see Figure 2 in Coetzee and Marshall 2003, Figure 12 here depicts longer setae), mostly seta

h 2 longer than the others (c 1 14-21, c 2 18-25, da, dm, dp 12-28, la 10-27, lm 13-40, lp 16-47, h 1,

h 3 10-29, h 2 27-59, p 1 17-34, p 2 -3 14-46); five pairs of distinct lyrifissures, ia postero-laterally to c 2, im between lm and lp, ih lateral to lp, ips lateral to ih close to latero-ventral border of notogaster, ip anterior to p 1 ; gla posterior to lp.

Lateral aspect ( Figure 12D ): PdI small lamina, directed forward; discidium rounded.

Ventral ( Figures 12B, D ): all setae smooth; epimeral setation 3-1-2-2, seta 1b (40-56)> 3b (18-33)> 4a, 4b (13-24)> 1a, 2a, 1c, 3a (9-19); six pairs of genital (g 1 15-19, g 2-6 12-16), one pair of aggenital (22-39), two pairs of anal (17-29) and three pairs of adanal (ad 1 14-18, ad 2-3 17-25) setae present; anal plates large (length 114-141, width not measured due to distortion of plates in many specimens), genital plates larger in females than males (female: length 106-115, males 84-92; width not measured due to distortion of plates in many specimens), also genital plates of females with distinct posterior interlocking triangle, males with weaker triangle.

Legs: matching drawings in Coetzee and Marshall (2003) ; tridactylous, middle claw strong, long hook-like claws, weakly serrated dorsally; porose areas present; for setation and solenidia see Table 4.
