The name is a noun in apposition, derived from the typelocality. Diagnosis. Distinguished from similar congeners by shapes of procursus (distal structures, Fig. 526; similar  S. atomariusand  S. uisib), bulb (processes of embolus, Fig. 529; similar  S. atomariusand  S. uisib), cheliceral apophyses (with proximal humps; Figs. 527, 528), shape of epigynum ( Fig. 473; wide plate with small round pockets; like  S. atomariusand  S. uisib), and spotted leg femora (only proximally). Male ( holotype). Total body length 6.2, carapace width 1.7. Leg 1: 43.6 (12.5 + 0.8 + 10.8 + 17.5 + 2.0), tibia 2: 8.0, tibia 3: 6.0, tibia 4: 8.8; tibia 1 L/d: 55. Habitus as in Figs. 436 and 437. Carapace ochre-yellow with brown median and very indistinct lateral marks, clypeus with indistinct pair of dark stripes, sternum slightly darkened medially, leg femora with some brown spots proximally, femora and tibiae with indistinct subdistal rings, abdomen monochromous pale whitish. Distance PME-PME 115 µm, diameter PME 150 µm, distance PME-ALE 55 µm, distance AME-AME 60 µm, diameter AME 135 µm. Ocular area slightly elevated, secondary eyes with small ‘pseudo-lenses’; deep thoracic pit. Chelicerae with conical proximal humps and distal apophyses ( Figs. 527, 528). Palps as in Figs. 457 and 458, coxa with distinct retrolateral apophysis, trochanter barely modified, femur with retrolateral furrow with distinct proximal rim, procursus with distinctive distal processes in dorsal view ( Fig. 526; retrolateral view as in  S. uisib; cf. Fig. 509), bulb with complex embolus, distinctive in prolateral view ( Fig. 529; dorsal view as in  S. uisib; cf. Fig. 512). Legs without spines, few vertical hairs, with curved hairs on tibiae and metatarsi 1 and 2; retrolateral trichobothrium on tibia 1 at 2.5%; prolateral trichobothrium present on tibia 1. Gonopore with two epiandrous spigots. Variation. Tibia 1 in4 other males: 8.9, 9.3, 10.0, 10.8.   FIGURES 526–529.  Smeringopus tombua. 526. Left procursus, dorsal view. 527–528. Male chelicerae, frontal and lateral views. 529. Left embolus, prolateral view. Scale lines: 0.3 mm. Female. In general similar to male; tibia 1 in 2 females: 9.3, 9.6. Epigynuma wide plate with round pockets ( Fig. 473; very similar  S. atomariusand  S. uisib); internal genitalia as in Fig. 474. Distribution. Only known from typelocality in southwestern Angola( Fig. 475).  Materialexamined.  Angola:  Namib Province: between Namib and Tômbua: typeabove; same data, 4♂ 3♀(3 vials) in SMF. 3747820878 1949-10-23 SMF A. de Barros Machado Angola -15.433333 Desert de Mocamedes 1285 12.183333 Porto Alexandre 86 87 Ang 1947.6 1 1 Namib Province holotype 3747820646 87 88
