Type. Male holotype from Rwanda, Butare [2°36’S, 29°44’E], vi.1971 (P. Nyalugaka), in MRAC ( 139117 , part) GoogleMaps .

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

Diagnosis. Distinguished from similar congeners by tip of procursus (distinctive membranous flap longer than sclerotized spine; Figs. 647, 648 View FIGURES 647–654 ), and shape of embolus (very similar S. peregrinus but narrower in prolateral view and without pointed process; Fig. 649 View FIGURES 647–654 ); 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. 596 View FIGURES 592–607 ; epigynum and cleared female genitalia otherwise similar S. peregrinoides and S. kalomo ).

Male (holotype). Total body length 7.2, carapace width 2.2. Leg 1: 49.5 (13.1 + 0.9 + 13.1 + 19.7 + 2.7), tibia 2: 9.3, tibia 3: 6.8, tibia 4: 9.5; tibia 1 L/d: 55. Habitus as in Fig. 562 View FIGURES 558–571 . Carapace ochre-yellow with brown median and lateral marks, clypeus with pair of dark stripes, sternum brown with light marks near bases of coxae 2–4 and medially, legs light brown, femora and tibiae with lighter tips and subdistal dark rings, abdomen ochre-gray with distinct dorsal and ventral pattern. Distance PME-PME 185 µm, diameter PME 170 µm, distance PME-ALE 70 µm, distance AME-AME 55 µm, diameter AME 160 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 ; apophyses slightly shorter); each apophysis with one modified hair at tip ( Fig. 663 View FIGURES 663–672 ). Palps as in Figs. 576 and 577 View FIGURES 572–583 , coxa with distinct retrolateral apophysis and shallow wide furrow, trochanter barely modified, femur with retrolateral furrow with distinct rim proximally, procursus with distinctive distal elements ( Figs. 647, 648 View FIGURES 647–654 ), bulb with distinctively shaped prolateral process on embolus (similar S. peregrinus but narrower in prolateral view; Fig. 649 View FIGURES 647–654 ). Legs without spines, few vertical hairs, with curved hairs ventrally on tibiae and metatarsi 1, retrolateral trichobothrium on tibia 1 at 3%; prolateral trichobothrium present on tibia 1. Gonopore with two epiandrous spigots ( Fig. 664 View FIGURES 663–672 ); ALS with eight spigots each ( Fig. 665 View FIGURES 663–672 ).

Variation. The color pattern is quite constant but variably distinct. Tibia 1 in 17 males: 9.3–18.1 (mean 13.8).

Female. In general similar to male; tibia 1 in 31 females: 10.0–15.7 (mean 11.9). Epigynum a simple plate mostly with poorly defined borders, with large semicircular pockets ( Figs. 596 View FIGURES 592–607 , 666 View FIGURES 663–672 ); internal genitalia as in Fig. 597 View FIGURES 592–607 (very similar S. peregrinoides and S. kalomo ).

Distribution. Known from Rwanda, Burundi, and eastern Congo D.R. (Sud-Kivu) ( Fig. 608 View FIGURE 608 ).
