Etymology. The species name is a noun in apposition taken from the type locality of the paratype.

Diagnosis. Males are similar to Stemmops servus Levi, 1964 (see Levi 1964, fig. 9) by the embolus coiled and filiform, and presence of embolic basal process ( Fig. 7 View FIGURES 5–9 ), but differ from this species by the embolus relatively short, filiform, with one lap around the embolic base, and by the shape of embolic base excavated posteriorly, embolus tip appears covered by the apex of the embolic basal process ( Fig. 7 View FIGURES 5–9 ).

Description. Male holotype (from Matozinhos, Mocambeiro, IBSP 180244): Total length 1.49. Carapace: length 1.19, width 0.60. Clypeus height: 0.08. Sternum: length 0.37, width 0.29. Chelicerae: length 0.12, width 0.06. Abdomen: length: 0.58, width 0.21, height 0.42. Leg formula IV/I/III/II. Segment length (I/II/III/IV): femora 0.71/0.42/0.48/0.71; patellae+tibiae 0.75/0.52/0.46/0.75; metatarsi+tarsi 0.84/0.73/0.65/0.84. Palp: femora 0.12, patellae 0.06, tibiae 0.06, cymbium 0.21. AME, PLE and PME biggest, ALE smaller. PME separated from each other by 0.06. Carapace circular ( Fig. 15 View FIGURES 10–23 ), brown with lateral dark brown dots. Clypeus concave, laterally. Chelicerae yellow. Labium subtriangular, yellow. Endites brown. Ocular region dark except between PME. Sternum dark brown, with dark dots.
