Etymology. The name is a latinized noun in the genitive case based on the modern name of the island, treated as a noun in apposition.

Description. Length 7.8–11.9 mm, width 4.2–6.2 mm. Black, dorsal surface glabrous, matte. Head transverse, nearly impunctate; gena impunctate, genal groove complete ( Fig. 11 ); antenna brown, antennomeres I–V nearly glabrous, VI with few golden setae apically, VII–XI bearing golden setae; pronotum transverse, convex, margins beaded, lateral margins rounded, widest at middle, anterior margin slightly elevated and slightly curved inward, bead fading medially, anterior angles rounded, basal marginal bead fading medially, basal angles obtuse,surface impunctate,shagreened at higher magnification; hypomeron glabrous, impunctate,

and shagreened; prosternum medially longitudinally raised, lacking pits, and glabrous, margined between coxae and behind, prosternal process with a raised, smooth lateral margin between coxae to posterior apex, median disc depressed and separated by shallow fine groove, glabrous. Elytron with shallow, fine, impunctate striae; 1 st and 2 nd striae converging anteriorly, always joined, interstriae flat, impunctate, and glabrous, surface shagreened. Mesoventrite nearly impunctate, sparsely setose; metaventrite nearly impunctate, bearing microsetae, without post-coxal, pit-like crenulations. Tibiae glabrous on dorsal surface, apical third of ventral surface with erect, golden setae, becoming dense, golden brush at apex. Abdomen without post-coxal, pit-like crenulations, surface shiny, nearly impunctate, and microsetose.

Distribution. Saint Lucia.

Remarks. More biological information is available on this species than any other. During a three-month inventory of Saint Lucia, this species was found on dead wood at 70 m to nearly 800 m elevation. The most informative record is taking this flightless species in a canopy Malaise trap, indicating they may live in dead wood in the canopy.
