Diagnosis. This species can be diagnosed by the elytron being evenly rounded laterally, without a trace of a lateral carina or angulate margin between seventh and eighth striae, and the surface of the head smooth and lacking any shagreening.
Description (male). Body oblong, reddish-black, legs similar color (Fig. 34); dorsal surface of head with extremely fine, widely spaced puntures, separated by 6 to 9 X their diameter, surface faintly shagreened near posterior margin, otherwise smooth; clypeus with 4 teeth anteriorly, mesal teeth acute, nearly parallel-sided, laterad pair acute, but much broader basally, with strongly diverging sides, clypeal-genal projections smaller (Fig. 7); dorsal ocular area large, eyes separated by a distance equal to 3.5 to 4X their transverse width (Fig. 7); elytral striae distinct, with fine punctures along length, elytral intervals very slightly convex, surface finely shagreened, with scattered fine punctures visible under high magnification; elytra evenly rounded laterally, without trace of lateral carina or angulate margin between seventh and eighth striae, punctures of eighth stria row variable in strength, with first and 5–10 much more distinct than remainder; protibiae with 3 teeth, distal end truncate, tooth not bending forward (Fig. 19); protibial spur broad, blunt and curved mesad near tip, reaching fourth tarsomere; mesosternal suture anteriorly rounded (Fig. 13); metafemur weakly arcuate; pygidium entirely margined, slightly convex, surface finely, sparsely punctured and smooth; aedeagus with basal piece apex acutely pointed posteriorly, parameres large, trapezoidal with acute tip (Fig. 25). Length: 3.2–4.3 mm, measured along midline from anterior margin of pronotum to tip of elytra.
Heads 7. Canthochilum brodzinskyorum; 8. Canthochilum magnum; 9. Canthochilum matthewsi; 10.
Canthochilum mimicum; 11. Canthochilum nebulonemi; 12. Canthochilum platycnemis.
Female: Differs from the male in being slightly larger in the small series on hand; the protibial spur is narrow, acute and less curved near tip; and the metatibia is very slightly less curved than in the male.

PARATYPES. 1 MALE — same data as holotype [WIBF]. 1 FEMALE — DOM. REP.: Prov. Pedernales; ca. 35 km N. Cabo Rojo, 1250 m; Las Abejas, 26 AUG– 9 SEP 1988, flight intercept trap; M. Ivie, Philips & Johnson. [WIBF].
Etymology. We take great pleasure in naming this species after Jacob and Mariannella Brodzinsky, who showed us great hospitality and assistance in Santo Domingo during our visits to the Dominican Republic.
Notes. The habitat of this species is a small pocket of moist broadleaf forest in the Sierra de Bahoruco near the Haitian border on the southern paleoisland. It is an unusually diverse and unique place, and although under legal protection as part of the Parque Nacional Sierra de Bahoruco, it is under constant threat.
