HOLOTYPE: Female. DOMIN. REP: Prov. San Juan, Pico Duarte weather sta., 2885 m, 07APR.–08JUL 1992, lindgren funnel, M. A. & R. O. Ivie ( USNM). (Specimen point mounted, gender label affixed to paper point; support card; locality label; holotype label.)

PARATYPES: Seven specimens. Dominican Republic: La Vega: Loma Rucilla & mountains, N, day not noted-VI-1938, 1524– 2439 m, Darlington ( MCZC, 2; AMNH, 1); 53 km SE Constanza, 9-VIII-1979, L. B. O’Brien ( WFBC, 1); Parque Nacional Armando Bermudez, N Pico del Yaque, 29- VII-1993, 2375 m, beating vegetation, D. Sikes & R. P. Rosenfeld ( MAIC, 2; WOPC, 1) .

DIAGNOSIS: The more narrow pronotum, more angular lateral pronotal tubercle, singular spine on the anterior margin of the protibia, and configuration of the elytral pattern (figs. 13, 14) conveniently distinguish the members of this species from the superficially similar specimens of Decorosa limatula .

DESCRIPTION: Size: Length 3.8–5.8 mm; width 1.0– 1.3 mm. Integumental Color: Cranium and pronotum light reddish brown; antennae yellow; elytra as in figure 13 and 14; legs predominantly yellow, tibiae infuscated; venter dark brown. Vestiture: Cranium and pronotum densely vested with pale decumbent setae. Head: Vertex about four times wider than width of eye (12:40); ratio of head width to width of pronotum 1.18 (67:57); antennae as in figure 4. Thorax: Pronotum only slightly longer than broad (60:58); pronotal lateral tubercle acute; side margins very sinuous; anterior margin conspicuously wider than posterior margin (56:47); apical region of protibial anterior margin with one spine. Abdomen: Aedeagus as in figures 19–22.

VARIATION: In one specimen the cranium and pronotum is dark brown rather than reddish brown and the expression of light and dark coloration of the elytral disc varies as indicated in figures 13 and 14. These figures represent the extremes in elytral color density among the species examined.

NATURAL HISTORY: Members of this species have been captured during June–August at altitudes ranging from 1524–2885 m.

DISTRIBUTION (fig. 46): This species is known from the highlands of the Cordillera Central of the Dominican Republic.

ETYMOLOGY: The trivial name is a dedicative patronym to express appreciation to Michael A. Ivie for his contributions to West Indian coleopterology.
