Type. Male holotype from Angola, Luanda Norte Province, 6 km NW of Dundo [7°20’S, 20°47’E], 24.ix.1946 (A. de Barros Machado), in SMF ( Ang 38.6 ) GoogleMaps .

Etymology. The name is a noun in apposition, derived from the type locality.

Diagnosis. Distinguished from similar congeners by tip of procursus (distinctive sclerotized and membranous elements; Figs. 679–681 View FIGURES 679–685 ), shape of embolus ( Figs. 682–684 View FIGURES 679–685 ; distinctive dorsal view); from S. peregrinoides also by longer and more downward directed cheliceral apophyses (similar S. peregrinus ; cf. Figs. 614, 615 View FIGURES 609–616 ) and absence of v-shaped or u-shaped structure frontally in female internal genitalia ( Fig. 604 View FIGURES 592–607 ).

Male (holotype). Total body length 5.5, carapace width 1.8. Leg 1: 35.5 (9.6 + 0.8 + 9.1 + 14.0 + 2.0), tibia 2: 6.5, tibia 3: 4.9, tibia 4: 6.9; tibia 1 L/d: 47. Habitus similar S. moxico (cf. Fig. 569 View FIGURES 558–571 ). Color pattern in general similar S. peregrinoides but rather indistinct (light colors apparently artificially darkened). Distance PME-PME 150 µm, diameter PME 140 µm, distance PME-ALE 60 µm, distance AME-AME 45 µm, diameter AME 140 µm. Ocular area slightly elevated, secondary eyes with ‘pseudo-lenses’; deep thoracic pit. Chelicerae with pair of distal apophyses as in S. peregrinus (cf. Figs. 614, 615 View FIGURES 609–616 ). Palps as in Figs. 584 and 585 View FIGURES 584–591 , coxa with distinct retrolateral apophysis and shallow wide furrow, trochanter barely modified, femur with retrolateral furrow with distinct rim proximally, procursus with distinctive distal membranous and sclerotized elements ( Figs. 679–681 View FIGURES 679–685 ), bulb with distinctively shaped prolateral process on embolus ( Figs. 682–684 View FIGURES 679–685 ). Legs without spines, few vertical hairs, with curved hairs ventrally on tibiae and metatarsi 1 and 2, retrolateral trichobothrium on tibia 1 at 3%; prolateral trichobothrium present on tibia 1.

Variation. Tibia 1 in 4 other males: 9.1, 9.2, 9.2, 9.7.

Female. In general similar to male; tibia 1 in 7 females: 7.1–8.5 (mean 7.7). Epigynum a simple plate with pair of pockets about 1.5–2 pocket-diameters apart ( Fig. 604 View FIGURES 592–607 ); internal genitalia as in Figs. 605 View FIGURES 592–607 and 685 View FIGURES 679–685 .

Distribution. Known from four localities in northeastern Angola and southern Congo D.R. ( Fig. 608 View FIGURE 608 ).
