Diagnosis.--Key characters: Ommatidial size coarse (Fig. 39b); prosternal process widened, expanded apically (Fig. 18); mesal antennal spines present (Figs. 8b, 9b); elytral humeri without epipleural tooth; pronotum without impunctate regions; longitudinally oriented rugosities present (Fig. 12c); tibial carinae absent; pronotal punctation confluent and elongated into longitudinal rugosities in most specimens; fourth antennomere much shorter than adjacent antennomeres and much less than half length of pronotum; antennomeres not strongly flattened toward apices; antennomere three half length of pronotum or less; sexual prosternal punctation present in males (Fig. 42b); elytra without bands of dense pubescence. Length: 5-7 mm.

Distribution and Diversity.--West Indies. Monotypic.

Discussion.--No specimens were available at the time of the phylogenetic analysis. I believe this genus is among those other West Indian taxa (including Curtomerus and Elaphidion portoricensis) which fell as a clade closely related to Elaphidion. Careful character analysis will have to be made to support or refute this idea, however.

This small taxon, like Elaphidionopsis, Curtomerus, and Nesiosphaerion, has an incomplete metasternal sulcus and sexual prosternal punctation in males. It differs from Elaphidionopsis in not having antennomeres flattened towards apices. It differs from Curtomerus in having mesal antennal spines. It differs from Nesiosphaerion in having a very short antennomere three, less than half length of pronotum (two-thirds length of pronotum in Nesiosphaerion).
