 Type Material. HOLOTYPE: Female. DOMIN. REP: Prov. La Vega; LaCienega, Parque Nac. HQ; 19u049N, 70u 529W. 1,100m; Rio Yaque N. 04APR1992; M. A. Ivie, D.Sikes, W.Lanier. (from WIBF, deposited in NMNH). PARATYPE (1 specimen): DOMIN.REP: Prov.LaVega; La Cienega, 1,100 m; 19u 04.079N, 70u 51.689W; 29 JULY 1999, at light; M.A.Ivie and K.A.Guererro. (1 WIBF).   
 Diagnosis. This species can be distinguished by its shiny golden-bronze to dark ferrugineous color, anterior angles of the pronotum acute and extremely produced (Fig. 223), and interstriae densely punctate, the punctures moderately impressed (Figs. 221, 223).   
 Description (female). 4.0–5.0 mm long, 2.0– 2.5 mm wide. Small, short, ovate moderately convex (Figs. 221, 222). Shining golden-bronze to dark ferrugineous; antennae, mouthparts and tarsi light ferrugineous. Head moderately punctate dorsally; punctures smaller than a single eye facet, slightly impressed; extremely short golden seta emerging from each puncture. Antenna clavate, antennomeres 7–10 transverse, forming a loose club; apical antennomere subcircular; antennomeres 7–11 with stellate sensoria. Mentum with acute median keel raised anteriorly to a point (Figs. 10, 12). Ventral portion of eye reaching subgenal sulcus (Fig. 9); postgena without distinct punctures. Dorsal surface of pronotum moderately punctate; punctures separated by 0.5–1.0 diameters. Pronotal marginal bead complete laterally, anterior margin with marginal bead effaced medially, posterior margin lacking marginal bead; anterior angles of pronotum acute, strongly produced and apically narrowly rounded; lateral edge of pronotum evenly curved to base; pronotum evenly convex (Fig. 223). Hypomeron without distinct punctures. Prosternal process ends in rounded form that abuts the anterior face of the mesoventrite, marginal grooves opposite coxae indistinct, not joined apically (Fig. 224). Elytral striae lightly impressed, present as rows of small punctures separated by 0.5–1.0 3 diameter, with a lightly impressed line through the middle of each puncture row; elytral interstriae flat, densely punctate, punctures moderately impressed; scutellary striae 4 punctures long; scutellum triangular, normal (Figs. 221, 223). Mesoventrite broad antero-posteriorly, weakly U-shaped, weakly excavate to receive prosternal process; metaventrite subequal to antero-postero length of mesocoxa (Fig. 224). Metathoracic wing fully developed. Legs short, punctate; all but mesofemora reaching beyond edge of elytron; tibia straight. Abdominal depressions on 4th and 5th ventrites reduced to indistinct slits (Fig. 74); intercoxal process of first ventrite rounded with apical nipple; ventral surface densely punctate, punctures weakly impressed (Fig. 224).   
 Male. No males were available for study.   
 Biology. This species has been taken at light in moist forest and beating vegetation at night.   
 Distribution. This species is endemic to Hispaniola. It has been collected at La Ciénaga in the province of La Vega of the Dominican Republic (Figs. 260, 264).   
 Etymology. This species has the anterior angles of the pronotum extremely produced, and is thus called productum.
