Etymology. The species name is a contraction of the name of the type locality.

Remarks. Although D. baviaans   sp. nov. is known from the male only and D. trilineata   sp. nov. from the female only, and both were collected in the same pitfall traps, we believe that they are distinctive species based on their considerable size differences ( D. trilineata   sp. nov. almost double the body length of D. baviaans   sp. nov.) and the very different abdominal markings (spotted in D. baviaans   sp. nov. and with narrow lateral stripes in D. trilineata   sp. nov.), particularly since all other species of Drassodella   have similar colouration and markings in both sexes ( Figs 93–110 View FIGURES 93–110 , 157–171 View FIGURES 157–171 ).

Diagnosis. Males of D. baviaans   sp. nov. are most similar to those of D. amatola   sp. nov., but can be separated by the larger median apophysis, the pointed embolus tip, and the lack of a prolateral tegular protrusion (compare Figs 180 View FIGURES 180–183 and 174 View FIGURES 172–175 ). Female unknown.

Description. Male (Holotype, Baviaanskloof, NCA 2010 /241). Measurements: CL 2.10, CW 1.24, AL 2.18, AW 1.16, TL 4.60 (3.88–4.60), FL 0.14, SL 1.14, SW 0.96, CH 0.12, AME-AME 0.06, AME-ALE 0.02, ALE- ALE 0.20, PME-PME 0.09, PME-PLE 0.13, PLE-PLE 0.40, PERW 0.53, MOQAW 0.17, MOQPW 0.21, MOQL 0.25.

Length of leg segments: I 1.54 + 0.76 + 1.28 + 1.22 + 1.02 = 5.82, II 1.34 + 0.64 + 1.00 + 1.04 + 0.76 = 4.78, III 1.04 + 0.58 + 0.76 + 0.88 + 0.62 = 3.88, IV 1.84 + 0.76 + 1.40 + 1.92 + 0.82 = 6.74.

General appearance as in Fig. 161 View FIGURES 157–171 . Carapace red-brown; white feathery setae forming upsilon marking, diverging behind fovea. Clypeus height equal to 1.25 AME diameter; AME smaller than ALE; AME separated by distance equal to 0.75 their diameter, AME separated from ALE by distance equal to 0.25 AME diameter; PME smaller than PLE; PME separated by distance equal to 1.26 their diameter, PME separated from PLE by distance equal to 1.63 PME diameter. Chelicerae dark-brown; promargin with three teeth, median tooth largest, distal tooth smallest; median tooth closer to proximal tooth; retromargin with two subequal widely space teeth. Endites orange, darker around margins. Labium orange, slightly longer than wide. Sternum brown. Legs with orange proximal segments, distal segments yellow. Leg spination: femora: I do 1 rl 1, II do 1 rl 1, III pl 2 do 2 rl 1, IV pl 1 do 2 rl 1; patellae: spineless; tibiae: I, II & III spineless, IV do 2 rl 3; metatarsi: I, II & III spineless, III rl 4 plv 2; palpal spination: femora do 2 rl 1 plv 2; patellae do 2 rl 3 plv 1; tibiae do 6 rl 2 plv 1; tarsi spineless. Abdomen brown; dorsal scutum extending two-thirds abdomen length; three pairs of dorsolateral spots of white feathery setae, one white spot above spinnerets; lateral sclerites above booklungs oval; venter grey, with large orange markings. Spinnerets pale. Palp yellow-brown; RTA moderately long, not obscured in ventral view by retrolateral heel of cymbium but positioned retrolateral of cymbium; in retrolateral view triangular, slightly curved dorsally, with broad base and sharp tip; cymbium narrow, 1.97 times longer than wide, narrowed to rounded point distally; embolus originating from distal prolateral mound, transverse and directed retrolaterally, with sharp needle-like tip; median apophysis large, hook-shaped ( Figs 88 View FIGURES 78–92 , 180–181 View FIGURES 180–183 ).
