Type. Male holotype from South Africa, Northern Cape Province, Hay [Distr.], Kogelbeen Cave (28°40’S, 23°21’E), entrance room of cave, 22.ii.1997 (L.N. Lotz), in NMBA ( 8153 part) GoogleMaps .

Etymology. The species is named for Leon L. Lotz from the National Museum in Bloemfontein who contributed many specimens for this revision.

Diagnosis. Distinguished from similar congeners by shapes of procursus (distal structures, Figs. 487, 488 View FIGURES 487–493 ; similar S. ubicki ), bulb (processes of embolus, Figs. 489, 490 View FIGURES 487–493 ), cheliceral armature (presence and position of proximal apophyses; Figs. 491, 492 View FIGURES 487–493 ), and shape of epigynum ( Fig. 463 View FIGURES 459–474 ; large pockets close together; similar S. similis ).

Male (holotype). Total body length 6.1, carapace width 2.0. Leg 1: 46.7 (12.5 + 0.8 + 11.7 + 19.1 + 2.6), tibia 2: 8.9, tibia 3: 7.2, tibia 4: 9.8; tibia 1 L/d: 51. Habitus as in Figs. 428 and 429 View FIGURES 424–437 . Carapace ochre-yellow with brown median and lateral marks, clypeus with pair of dark stripes, sternum ochre-yellow with brown pattern, leg femora and tibiae with subdistal dark rings, abdomen with dorsal and ventral pattern. Distance PME-PME 150 µm, diameter PME 160 µm, distance PME-ALE 90 µm, distance AME-AME 55 µm, diameter AME 140 µm. Ocular area slightly elevated, secondary eyes with very indistinct ‘pseudo-lenses’; deep thoracic pit. Chelicerae with proximal humps and distal apophyses ( Figs. 491, 492 View FIGURES 487–493 ), each distal apophysis provided with one modified hair ( Figs. 514, 515 View FIGURES 514–525 ). Palps as in Figs. 447 and 448 View FIGURES 438–450 , coxa with distinct retrolateral apophysis, trochanter barely modified, femur with retrolateral furrow with distinct proximal rim ( Fig. 516 View FIGURES 514–525 ), procursus with distinctive distal processes in dorsal view ( Fig. 488 View FIGURES 487–493 ; retrolateral view as in Fig. 487 View FIGURES 487–493 ), bulb with distinctive complex embolus ( Figs. 489, 490 View FIGURES 487–493 ). 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 ( Fig. 518 View FIGURES 514–525 ); ALS with eight spigots each ( Fig. 519 View FIGURES 514–525 ).

Variation. Tibia 1 in 10 other males: 7.0–11.0 (mean 8.9). Some specimens from eastern localities (Bloemfontein, Edenville) have identical palps but lack the proximal cheliceral humps. They are assigned tentatively.

Female. In general similar to male; triads closer together (distance PME-PME 115 µm); tibia 1 in 33 females: 4.7–10.2 (mean 7.3). Some darker specimens with black marks proximally on femora. Epigynum a simple plate with large pockets close together ( Fig. 463 View FIGURES 459–474 ); internal genitalia as in Figs. 464 View FIGURES 459–474 and 493 View FIGURES 487–493 .

Distribution. Widely distributed in central and northwestern South Africa ( Fig. 475 View FIGURE 475 ).
