Chelicerae, legs and palps pale yellow, lighter than prosoma; legs with brownish gray marks at the base of spines. Labium pale brown, distally pale orange. Endites pale yellowish orange. Sternum pale yellowish orange with pale brown margins.

diagnosis
Diagnosis. Males of S. soca sp. n. resemble those of S. pumilla by the embolus with a bifid basal projection (Figs 108, 111). They are distinguished from the latter species by the embolus with no additional projections (medial spine-like projection present in S. pumilla) and by the basal projection with dorsal branch wide, concave and ventral branch shorter, laminar, distally rounded (dorsal branch tapering and ventral branch longer and distally blunt in S. pumilla). Females are unknown.
distribution
Distribution. Only known from the type locality in Trinidad & Tobago (Fig. 118).
etymology
Etymology. The specific name refers to a type of dance music common in Trinidad, which is a mix of Calypso, Indian music and rhythms; noun in apposition.
