Type. Male holotype from Uganda, Kasese District, Ruwenzori Mts. , between Nyabitaba Hut and Guy Yeoman Hut (~0°20.6–21.5’N, 29°55.6–58.7’E), 2660–3450 m a.s.l., 2.xii.2010 (B.A. Huber), in ZFMK (Ar 8483) .

Etymology. The name is a noun in apposition, derived from Bujongolo Shelter, the highest African locality at which pholcids have been found so far.

Diagnosis. Easily distinguished from most known congeners by long process near male palpal tarsal organ (as in S. chogoria ; cf. Figs. 131, 132 View FIGURES 131–137 ); also by shapes of procursus and embolus (very similar S. chogoria ; cf. Figs. 131–134 View FIGURES 131–137 ); from very similar S. chogoria only by minor details of procursus tip (membranous part transparent rather than whitish; distal apophysis slightly shorter), semitransparent bulbal process (curved rather than straight), and female genitalia (shorter anterior epigynal plate; border of anterior plate with whitish area separating pair of black structures at rim: Fig. 128 View FIGURES 115–130 ; pore plates much narrower: Fig. 137 View FIGURES 131–137 ).

Male (holotype). Total body length 7.7, carapace width 2.7. Leg 1: 58.1 (14.3 + 1.2 + 14.7 + 23.2 + 4.7), tibia 2: 11.2, tibia 3: 8.5, tibia 4: 11.7; tibia 1 L/d: 50. Habitus as in Fig. 117 View FIGURES 115–130 . Carapace with wide median and lateral brown bands with indistinct borders, clypeus with pair of wide brown bands, sternum dark brown, legs ochre-brown, femora and tibiae with darker subdistal rings, abdomen with distinct pattern dorsally and ventrally. Distance PME-PME 250 µm, diameter PME 220 µm, distance PME-ALE 175 µm, distance AME-AME 90 µm, diameter AME 150 µm. Ocular area slightly elevated, secondary eyes with small ‘pseudo-lenses’; deep thoracic pit. Chelicerae very similar S. chogoria ( Fig. 127 View FIGURES 115–130 ; apophyses slightly shorter). Palps as in Figs. 121 and 122 View FIGURES 115–130 , very similar S. chogoria (differences of procursus shapes between Figs. 120 and 122 View FIGURES 115–130 result from slightly different angles of view), coxa with indistinct bulge, trochanter barely modified, femur with retrolateral indentation but no furrow, without proximal rim and without apophysis, cymbium with long projection near tarsal organ, procursus with distinctive distal elements (cf. Figs. 131, 132 View FIGURES 131–137 ; distal apophysis slightly shorter), bulb with complex embolus with two processes, one sclerotized, other mostly membranous (cf. Figs. 133, 134 View FIGURES 131–137 ; membranous part more curved). Legs without spines, few vertical hairs, with curved hairs ventrally and dorsally on all tibiae and metatarsi, also on femora 1 and 2 (ventrally), retrolateral trichobothrium on tibia 1 at 2.5%; prolateral trichobothrium present on tibia 1.

Variation. Tibia 1 in 7 other males: 9.9–15.6 (mean 12.8). Some males with ‘normal’ (posteriorly not widened) abdomen ( Fig. 118 View FIGURES 115–130 ).

Female. In general similar to male; tibia 1 in 20 females: 8.7–14.8 (mean 12.0). Epigynum anterior plate roughly triangular, without pockets, posterior rim with distinctive pair of dark bulges ( Figs. 128, 129 View FIGURES 115–130 ); arc-shaped posterior plate; internal genitalia as in Figs. 130 View FIGURES 115–130 and 137 View FIGURES 131–137 .

Distribution. Only known from higher elevations (mostly between 2000 and 3800 m a.s.l.) in the Ruwenzori Mountains ( Uganda, Congo D.R.) ( Fig. 58 View FIGURE 58 ).
