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 .
