Diagnosis. The females of S. longimana can be easily distinguished by their first pair of legs being remarkably stouter and longer than the rest, resembling the general appearance of a palpimanid spider ( Fig. 30A View Figure 30 ). The epigynal plate possesses CO hidden by a parallel pair of pockets arranged vertically ( Fig. 30C View Figure 30 ), similar to that seen in S. cambridgei but more discrete. Males resemble those of S. arenata sp. nov., S. cambridgei , S. similis sp. nov. and S. spiralis sp. nov. by having the single-tipped and curved RTA and by the tegulum and cymbium retro-ventrally inclined, but these two latter copulatory structures are more elongated than rounded in S. longimana ( Fig. 31C View Figure 31 ) The males of all these species also share the long thin and filiform barbs on tibiae and metatarsi I ( Fig. 31A View Figure 31 ), but S. longimana is easily distinguished by the reduced body size compared to the other species.

Description. Female (ZMB 48561): Anterior eyes arranged in a recurved row ( Fig. 30B View Figure 30 ) and posterior ones in a straight line; prosoma yellow with large brown or black patches, covered by many hyaline short setae ( Fig. 30A View Figure 30 ). Leg I predominantly brown, with few yellow spots on femora, while the legs II, III and IV are yellow with marked brown patches ( Fig. 30A View Figure 30 ). Opisthosoma obovate and wider on its posterior-lateral portion, covered by clavate setae; yellowish on the sides and with black circular spots delimiting a trapezoid greyish-brown area on the dorsum ( Fig. 30A View Figure 30 ). Spermathecae granulose, preceded by copulatory ducts directed sideways and a pair of globose anterior chambers ( Fig. 30D View Figure 30 ).

Male (AMS KS.22517): Eye arrangement as in female; clypeus possessing a set of median macrosetae ( Fig. 31B View Figure 31 ), prosoma light-brown with a longitudinal darker marking on the median area ( Fig. 31A View Figure 31 ). Leg I becoming gradually darker from the proximal part of the tibia to the tarsus; metatarsus I slightly curved ( Fig. 31A View Figure 31 ). Other leg characteristics as in female. Palp with oval tegulum and embolus running along the prolateral side of the cymbium, laminar with a welldeveloped pars pendula ( Fig. 31C View Figure 31 ); RTA curved retro-laterally and pointing ventrally, parallel to the tegulum ( Fig. 31D View Figure 31 ).

Measurements: eye diameters and interdistances: AME 0.05, ALE 0.12, PME 0.10, PLE 0.12, AME–AME 0.09, AME–ALE 0.06, PME–PME 0.08, PME–PLE 0.12, MOQ length 0.25, width 0.20; leg formula: 1-2-4-3: leg I—femur 2.10/ patella 1.12/ tibia 2.27/ metatarsus 1.50/ tarsus 0.56/ total 7.55; II—1.54/ 0.74/ 1.46/ 1.02/ 0.55/ 5.31; III—1.04/ 0.59/ 0.80/ 0.52/ 0.46/ 3.41; IV—1.50/ 0.63/ 1.06/ 0.74/ 0.49/ 4.42.
