Wunderlich [detritus in reeds], SMF— not examined); Bosselaers et al. 2009: 22, figs 4, 16–21 (♂ ♀); Bosselaers 2010: 23, figs 10–13, 21 (♂); Wunderlich 2012: 20, figs 11–14 (♂ ♀).

Diagnosis. The male of this species is most similar to that of T. humus sp. nov. in sharing an embolus with a long slender distal section but can be distinguished by the narrower proximal section (almost as broad as the tegulum in T. humus sp. nov.) and the tip of the embolus being directed at 1 o’clock as opposed to 11 o’clock in the latter species (cf. Figs 8A and 13A). The female of this species can be distinguished from other Afrotropical congeners by the funnel-shaped copulatory ducts that rapidly narrow after the copulatory opening (Fig. 8C, D).

Male.

Carapace reddish-orange; eye region darker, with brown rings around eyes (Fig. 6A, B); AME and ALE approximately equal in size; clypeus height equal to approximately AME diameter; AME separated by about one diameter; AME separated from ALE by about 0.2× AME diameter; PLE slightly larger than PME; PME separated by approximately 1.25× their diameter; PME separated from PLE by approximately 0.5× PME diameter. Chelicerae orange, pale orange towards fang base, endites and labium slightly lighter; three promarginal teeth, median tooth largest, distal tooth smallest; two retromarginal teeth, distal tooth largest. Sternum pale yellow, light brown towards borders. Abdomen creamy white to pale yellow dorsally, mottled brown over last 3/4 of abdomen (Fig. 6A, B); first pair of sigilla pale brown, anterior to midpoint, second pair slightly darker, posterior to midpoint of abdomen. Legs pale yellow to pale brown; legs I and II more robust, slightly darker than III and IV. Palp pale yellow to brown; retrolateral PA large, triangular, slightly curved; CY pear-shaped; TE oval, slightly more than 1/2 CY length; SP gradually curved, with sharp proximal bend; EM originating prodistally, with proximal section approximately half the width of TE, distal section long, curving clockwise, prodistally from its base, with tip directed at 1 o’clock (Figs 5A–E, 8A, B).

Female.

Length of leg segments: I 3.56 (1.11, 0.48, 0.83, 0.62, 0.52); II 3.28 (1.00, 0.50, 0.78, 0.60, 0.40); III 2.68 (0.80, 0.38, 0.55, 0.65, 0.30); IV 3.97 (1.13, 0.48, 0.98, 0.98, 0.40).

Carapace reddish-brown; eye region brown, dark brown to black rings around eyes (Fig. 6B); AME and ALE equal in size; clypeus height equal to approximately AME diameter; AME separated by distance equal to 0.4× their diameter; AME separated from ALE by approximately 0.2× AME diameter; PME slightly larger than PLE; PME separated about one diameter; PME separated from PLE by about 0.7× PME diameter.

Sternum pale brown, darker towards border. Abdomen with pale yellow to pale grey dorsum, with pale brown mottling over surface, darker posteriorly above spinnerets [in Ethiopian specimens, with grey sides and chevrons in posterior half; Fig. 6C, D]. Legs I to IV uniform pale yellow to pale brown; anterior legs slightly more robust, slightly darker than posteriors. Epigyne weakly sclerotised, with broad, arched, anteriorly directed AT housing CO; CD directed anteriorly, bending back sharply before entering large, circular, medially situated ST II, separated by 3/4 their diameter; Cd directed mesally, then posteriorly along midline, making complete loop in thickened posterior section before diverging posterolaterally, entering oval ST I near epigastric fold on their anteromesal margins; ST I separated by about their diameter (Figs 5F, 8C, D).

Distribution. Widely distributed in central, eastern and southern Africa (Fig. 9). Considering the species has not yet been recorded in West Africa, it is plausible that it may have been introduced from continental Africa to the Canary Islands, from where it was originally described (Wunderlich 1987), or vice versa.
