The females of <i>S. longimana</i> 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). The epigynal plate possesses CO hidden by a parallel pair of pockets arranged vertically (Fig. 30C), similar to that seen in <i>S. cambridgei</i> but more discrete. Males resemble those of <i>S. arenata</i> sp. nov., <i>S. cambridgei</i>, <i>S. similis</i> sp. nov. and <i>S. spiralis</i> 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 <i>S. longimana</i> (Fig. 31C) The males of all these species also share the long thin and filiform barbs on tibiae and metatarsi I (Fig. 31A), but <i>S. longimana</i> is easily distinguished by the reduced body size compared to the other species. <b>Description</b>. <b>Female</b> (ZMB 48561): Anterior eyes arranged in a recurved row (Fig. 30B) and posterior ones in a straight line; prosoma yellow with large brown or black patches, covered by many hyaline short setae (Fig. 30A). 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). 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). Spermathecae granulose, preceded by copulatory ducts directed sideways and a pair of globose anterior chambers (Fig. 30D). <i>Measurements</i>: eye diameters and interdistances: AME 0.06, ALE 0.11, PME 0.09, PLE 0.11, AME–AME 0.10, AME–ALE 0.06, PME–PME 0.14, PME–PLE 0.19, MOQ length 0.30, width 0.27; leg formula: 1-2-4-3: leg I—femur 1.79/ patella 1.00/ tibia 1.61/ metatarsus 1.01/ tarsus 0.38/ total 5.79; II—1.41/ 0.77/ 1.22/ 0.86/ 0.48/ 4.74; III—1.02/ 0.57/ 0.73/ 0.55/ 0.36/ 3.23; IV—1.38/ 0.56/ 0.98/ 0.73/ 0.47/ 4.12.

Leg I becoming gradually darker from the proximal part of the tibia to the tarsus; metatarsus I slightly curved (Fig. 31A). 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); RTA curved retro-laterally and pointing ventrally, parallel to the tegulum (Fig. 31D). <i>Measurements</i>: 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.
