Zayas Collection Notes. Zayas (1988) described this species from six examples from Cupeyal in his collection. However, in January 2008, there were nine specimens in the collection, all from Cupeyal. The specimen marked with a red Tipo label is here designated as the lectotype and the first five of the remaining eight specimens are here designated as paralectotypes.

Diagnosis. This species can be distinguished by the sharp anterior angles of the pronotum ( Fig. 175 View Figs ), long scutellary striae nearly meeting the median suture of the elytra ( Fig. 175 View Figs ), and the prosternal process rounded to a point, with distinct marginal grooves opposite coxae joined apically and the area between the marginal grooves concave, becoming convex at apex ( Fig. 176 View Figs ).

Redescription (modified from Zayas 1988) (male). 6.5–7.0 mm long, 4.0– 4.5 mm wide. Body elongate, slightly convex ( Figs. 173, 174 View Figs ). Purple to black; antennae, mouthparts and tarsi tending to be the same color as the legs. Head densely punctate, largest punctures subequal in size to single eye facet and moderately impressed; extremely short golden seta emerging from each puncture. Antenna weakly clavate, nearly filiform; antennomeres 7–10 weakly widened apically, forming a loose, elongate club; apical antennomere longitudinally ovate; antennomeres 7–11 with stellate sensoria. Mentum with acute median keel raised anteriorly to a point ( Figs. 10, 12 View Figs ); ventral portion of eye reaching subgenal sulcus ( Fig. 9 View Figs ); postgena with circular punctures ( Fig. 12 View Figs ). Dorsal surface of pronotum densely punctate; punctures separated by 0.5–1.5 diameters. Pronotal marginal bead complete laterally, anterior and posterior margins with marginal bead effaced medially; anterior angles of pronotum acute, moderately produced and apically narrowly rounded; lateral edge of pronotum sinuate at base; pronotum evenly convex ( Fig. 175 View Figs ). Hypomeron with distinct punctures ( Fig. 27 View Figs ). Prosternal process apically rounded to a point; distinct marginal grooves opposite coxae joined apically, area between marginal grooves concave between coxae, becoming convex at apex ( Fig. 176 View Figs ). Elytral striae not impressed, present as small discontinuous punctures; punctures separated by 0.5–1.0 diameters; appearing as a fine stria; elytral interstriae flat; densely punctate; scutellary striae 4– 10 punctures long, nearly reaching the elytral suture; scutellum triangular, normal ( Figs. 173, 175 View Figs ). Mesoventrite thin antero-posteriorly, deeply excavate, U-shaped, receiving prosternal process; metaventrite subequal in antero-postero length of mesocoxa ( Fig. 176 View Figs ). Metathoracic wing fully developed. Legs short, punctate, apical 1/4 of femur reaching beyond elytron; tibiae slightly apically curved ventrally; metatibia with apical ventral tooth vestigial ( Fig. 58 View Figs ). Abdominal depressions on 4th and 5th ventrites present reduced to slightly impressed slits ( Fig. 74 View Figs ); intercoxal process of first ventrite broadly triangular apically; ventral surface densely punctate; punctures moderately impressed ( Fig. 176 View Figs ).

Female. Identical to male, except tibiae straight and metatibia lacking ventral apical tooth.

Biology. Unknown.

Distribution. This species is endemic to Cuba and has only been collected at Cayamas in Villa Clara Province ( Figs. 258 View Figs , 264 View Figs ).
