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 (

): 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
,

, 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 (

ro
(20-31) smooth,
le

Gnathosoma (

, palp setation 0-2-1-3-9+1ω, palp solenidion ω and eupathidium

Notogaster (
