( Figs. 50 View Figs , 140–143 View Figs , 262 View Figs , 281 View Figs )

Type Material. HOLOTYPE: Male. Mt. Basil; N. Haiti; 4,700 ft; Sept. 9/ 1934; Darlington. ( MCZC)   . PARATYPE (1 specimen, male): 1 MCZC specimen with same label data as holotype   .

Diagnosis. This species can be distinguished by its broad, ovate body form ( Fig. 140 View Figs ), anterior angles of pronotum more broadly rounded ( Fig. 142 View Figs ), intercoxal process of first ventrite broadly triangular at base ( Fig. 143 View Figs ), and broad mesoventrite.

Description (male). 8.5–10.0 mm long, 5.5–6.0 mm wide. Body elongate, moderately convex, broad, weakly tapered apex ( Figs. 140, 141 View Figs ). Shining dark ferrugineous; antennae, mouthparts, and tarsi ferrugineous. Head densely punctate dorsally, punctures smaller than a single eye facet, lightly impressed; extremely short golden seta emerging from each puncture. Antenna weakly clavate, nearly filiform; antennomeres 5–10 weakly widened forming a loose, elongate club; apical antennomere longitudinally ovate; antennomeres 5–11 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 without distinct punctures. Dorsal surface of pronotum densely punctate; punctures separated by 0.5–1.0 diameters. Pronotal marginal bead complete laterally, anterior margin with marginal bead effaced medially, posterior margin without marginal bead; anterior angles of pronotum acute, moderately produced and apically narrowly rounded; lateral edge of pronotum weakly sinuate at base; pronotum evenly convex ( Fig. 142 View Figs ). Hypomeron without distinct punctures. Prosternal process apically rounded; indistinct marginal grooves opposite coxae not joined apically ( Fig. 143 View Figs ). Black, except under a microscope with light elytra appearing darkly ferrugineous with rows of black squares following elytral striae; elytral striae not impressed, present as small discontinuous punctures; elytral interstriae flat, densely punctate; scutellary striae 6–10 punctures long, nearly meeting the elytral suture; scutellum triangular, normal ( Figs. 140, 142 View Figs ). Mesoventrite broad antero-posteriorly, shallowly excavate, widely V-shaped, receiving prosternal process; metaventrite subequal in antero-postero length of mesocoxa ( Fig. 143 View Figs ). Metathoracic wing fully developed. Legs long, slender, punctate, apical portion of femur reaching beyond elytron; tibiae ventrally apically weakly curved; small, reduced ventral apical tooth on meso- and metatibia ( Fig. 50 View Figs ). Abdominal depressions on 4th and 5th ventrites reduced to indistinct slits ( Fig. 74 View Figs ); intercoxal process of first ventrite broadly apically triangular; ventral surface densely punctate; punctures weakly impressed ( Fig. 143 View Figs ).

Female. No females were available for study.

Biology. Unknown.

Distribution. This species is endemic to Hispaniola and is only known from the type locality of Mt. Basil in Artibonite Deptartment of Haiti ( Figs. 261 View Fig , 262 View Figs ).

Etymology. This species is named for Mount Basil, the mountain from which it is known.
