Females of <i>S. monulfi</i> resemble those of <i>S. armata</i> in having a trapezoid opisthosoma, being cryptic and robust in form, having legs bearing several stout projections and setiferous tubercles and by the median spire on thoracic portion of prosoma. However, they can be distinguished by their more flattened and wider prosoma, bigger dorsal projections on patellae and tibiae I and II (Fig. 32A), and epigynal plate with wide CO, depressed atrium and median septum (Fig. 32C). Males are diagnosed by their sclerotized embolus (Fig. 33C) and short and laminar RTA that resembles a shape of an axe blade in retro lateral view (Fig. 33D). <b>Description</b>. <b>Female</b> (KS.108712): Prosoma predominantly reddish-brown with a small median spire on the cephalic portion (Fig. 32B), covered by many whitish setae on the posterior slope and sides of cephalic area (Fig. 32A); anterior eye row recurved and posterior straight; cephalic and ocular projections discrete (Fig. 32B). Legs dark-yellow with brown tinges on the distal portion of femora, patellae and tibiae. These same leg segments bear acute projections with a terminal macrosetae and covered by smaller hyaline ones (Fig. 32A). Opisthosoma trapezoid, predominantly light-yellow with brownish anterolateral spots. Epigynum with segmented spermathecae, glandular-heads with many perforations and anterior chambers reduced (Fig. 32D). <i>Measurements</i>: eye diameters and interdistances: AME 0.10, ALE 0.15, PME 0.12, PLE 0.09, AME–AME 0.14, AME–ALE 0.11, PME–PME 0.30, PME–PLE 0.12, MOQ length 0.44, width 0.25; leg formula: 1-2-3-4: leg I—femur 3.85/ patella 2.26/ tibia 2.87/ metatarsus 2.00/ tarsus 1.22/ total 12.20; II—3.62/ 2.06/ 2.44/ 1.79/ 1.12/ 11.03; III—2.62/ 1.25/ 1.84/ 1.44/ 0.90/ 8.05; IV—2.78/ 1.21/ 1.66/ 1.30/ 0.77/ 7.72.

Anterior metatarsi and tarsi (I and II) light-brown; whitish setae clustered on the median region of the posterior slope of prosoma and on the sides of cephalic area, occurring also on the lateral margin of the clypeus and between the ALE and AME (Fig. 33B). Opisthosoma trapezoid and dark-yellow with lateral and posterior darker spots. Palpi short with Pcym rounded and RTAvbr truncated (Fig. 33C,D). <i>Measurements</i>: eye diameters and interdistances: AME 0.07, ALE 0.13, PME 0.08, PLE 0.06, AME–AME 0.07, AME–ALE 0.05, PME–PME 0.16, PME–PLE 0.05, MOQ length 0.23, width 0.25; leg formula: 1-2-4-3: leg I—femur 1.45/ patella 0.81/ tibia 1.08/ metatarsus 0.81/ tarsus 0.41/ total 4.56; II—1.43/ 0.73/ 1.00/ 0.77/ 0.43/ 4.36; III—0.99/ 0.52/ 0.73/ 0.65/ 0.42/ 3.31; IV—1.04/ 0.68/ 0.67/ 0.62/ 0.35/ 3.36.
