Figs. 2, 19, 30–31, 42–45, 65–72

Type. Male holotype from Uganda, Kanungu District, Bwindi Impenetrable National Park, waterfall trail near Buhoma (0°59.8’– 1°00.2’S, 29°36.9–37.2’E), ~ 1500–1600 m a.s.l., 22.xi.2010 (B.A. Huber), in ZFMK (Ar 8490)   .

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

Diagnosis. Distinguished from similar congeners (other species of the rubrotinctus   group) by shapes of procursus and embolus ( Figs. 65–67, 70–71); from most (except S. rubrotinctus   ) also by deeply indented epigynum ( Figs. 42–45); from most other congeners by long apophyses on male chelicerae ( Figs. 68, 69).

Male (holotype). Total body length 5.3, carapace width 1.7. Leg 1: 41.9 (10.3 + 0.7 + 10.6 + 17.7 + 2.6), tibia 2: 7.3, tibia 3: 5.7, tibia 4: 8.2; tibia 1 L/d: 63. Habitus as in Fig. 19. Carapace with wide median and lateral brown bands, clypeus and sternum dark brown, leg femora and tibiae with indistinct subdistal rings, abdomen with indistinct pattern dorsally and ventrally. Distance PME-PME 175 µm, diameter PME 175 µm, distance PME-ALE 90 µm, distance AME-AME 45 µm, diameter AME 115 µm. Ocular area slightly elevated, secondary eyes with indistinct ‘pseudo-lenses’; deep but small thoracic pit. Chelicerae as in Figs. 68 and 69, with pair of strong apophyses. Palps as in Figs. 30 and 31, coxa with indistinct bulge, trochanter barely modified, femur with deep retrolateral furrow with distinct rim proximally, ventral end of rim with apophysis, cymbium without projection near tarsal organ, procursus with distinctive tip with ventral bifid apophysis and whitish prolateral process ( Figs. 65–67), bulb with relatively simple branched embolus ( Figs. 70, 71). Legs without spines, few vertical hairs, with curved hairs ventrally and dorsally on tibiae and metatarsi 1 and 2, retrolateral trichobothrium on tibia 1 at 2%; prolateral trichobothrium present on tibia 1.

Variation. Tibia 1 in 2 other males: 10.2, 10.3. The cheliceral apophyses vary slightly in width and length.

Female. In general similar to male; tibia 1 in 4 females: 8.3, 9.0, 9.1, 10.0. Epigynum anterior plate with large indentation ( Figs. 42–44; very similar S. rubrotinctus   ), without pockets; posterior plate simple, not projecting; internal genitalia as in Figs. 45 and 72.

Distribution. Known from southwestern Uganda and eastern Congo D.R. (Nord-Kivu, Sud-Kivu) ( Fig. 58).
