Length male, 4.5–6.0 mm; female,
4.7–5.8 mm
. Integument black, shining. Eyes separated by a distance about one-half width rostrum at midlength. Rostrum 1.03–1.13x length elytra in male; 1.20–1.36x length elytra in female. Antennal insertion at about apical 1/
3 in
male, slightly beyond midlength in female. Prothorax constricted anteriorly, globose, widest at about middle; punctures widely spaced, very small, very shallow on disc and laterally on flanks; no setae present. Elytra in dorsal view widest at midlength, lateral margins convergent both anteriorly and posteriorly; humeri fully reduced, not at all angulate; no setae present. Strial punctures evident, small, shallow; striae not impressed. Membranous wings absent. Abdominal ventrite 1 of male in middle near posterior margin with two small raised patches of fine setosity; of female, uniformly convex in middle near posterior margin. Ventrite 5 flattened medially in male, rounded in female. Legs with front femora with ventral margin with small sharp tooth, middle and hind femora each with small blunt tooth; tarsal claws lacking small basal tooth. Aedeagus (fi.g 48) widest towards apex, internal sac with pair of elongate thick basal sclerites subparallel. Female not dissected.

Derivation of species name:
This species is named ‘lucidus’ after its shining, almost glabrous and impunctate appearance.
Comments:
This species is very similar to
S. delauneyi
from
Guadeloupe
but
S. lucidus
has a small basal tooth on each tarsal claw, the setose patches on ventrite 1 of the abdomen of males are located at the posterior margin of the ventrite, and the basal sclerite of the internal sac of the male genitalia is different.
