ETYMOLOGY: Named for the African country
Namibia
.
DIAGNOSIS: Distinguished from known congeners by the much larger procursus (compare figs. 322 323), from
N. minuta
also by the curved bulbal apophysis (compare figs. 321, 324), and the wider-than-long epigynum (compare figs. 329, 331); from
N. subtilissima
by the shorter and thicker cheliceral apophyses (compare fig. 325 with fig.
489 in
Simon, 1893b), and the wider epigynum (compare figs. 313, 331).
MALE (
holotype
): Total length 1.25, carapace width 0.56; leg 1: 3.07 (0.84+0.19 +0.84+0.81+0.39), tibia 2: 0.71, tibia 3: 0.61, tibia 4: 0.94 (!); tibia 1 l/d: 13. Habitus and prosoma shape as in
N. minuta
(cf. figs. 315 318); entire prosoma ochre to light brown; carapace without thoracic groove, sternum with indistinct tiny frontal humps; chelicerae with pair of diverging, distally slightly hooked frontal apophyses, without stridulatory ridges (figs. 325 326). Palps as in figs. 327 328, coxa without retrolateral apophysis, femur almost cylindrical, widened distally, tibia enlarged, procursus as in fig. 323; tarsal organ capsulate; bulb with slightly curved, almost translucent ventral spine and short embolar division (fig. 324). Legs monochromous ochre-yellow; without spines, without curved and vertical hairs; retrolateral trichobothrium of leg 1 at 60%; tarsus 1 with ~ 3 4 pseudosegments. Opisthosoma gray, with darker spots dorsally, genital plate light brown, wide; gonopore with four epiandrous spigots (fig. 125); ALS with several piriform gland spigots (fig. 152).
FEMALE (
paratypes
): Total length (N = 4) 1.3 1.6, tibia 1 (N = 5) 0.61 0.71 (x¯ = 0.68). In general very similar to male, but opisthosoma in all females monochromous gray. Epigynum simple flat plate, wider than long, with light median band ending frontally in pocket (fig. 331); dorsal view as in fig. 332 (I could not find pore plates).
