Paratypes deposited in the EMEC, UNAM, CNCI, USNM, TAMU, JCPC, HHPC, JEWC.

Male. Form robust, subcylindrical, tapering apically. Integument black to piceous, densely clothed with short, fine, grayish recumbent pubescence, a few longer, erect setae along weakly pronounced basal elytral crests; pronotum and elytra without pubescent fasciae or vittae. Head with front convex; median line moderately impressed, extending to occiput, widened at the base of the antennal tubercles in a flattened diamond to triangularly shaped denuded area; frons, area behind and between the eyes, tubercles, dorso­lateral areas of the gena, and basal margins covered with gray pubescence; upper lobes of the eyes separated by width of scutellum base, lower lobes elongate­ovate and distinctly longer than the height of the gena directly below them. Antennae slender, surpassing elytra by at least 4 segments, moderately clothed with short, golden­gray pubescence, all segments annulate at apical one­half to one­third, third segment slightly longer than scape, fourth one­sixth longer than scape, fifth distinctly shorter than scape, sixth and seventh nearly equal in length, shorter than fifth, remaining segments subequal or slightly decreasing in length, eleventh the shortest (other than second); scape elongate, attaining or extending slightly beyond pronotal tubercles, feebly carinate, cylindrical, widest at apical two­thirds, impressed below on apical one­fourth to one­third before apical process, apical process nearly symmetrical, evenly rounded, impressed behind. Pronotum cylindrical, width across tubercles approximately equal to dorsal length, slightly narrower posterior to lateral tubercles than anteriorly, moderately punctate above and on sides, punctures separated by 1–3 times their diameter, as large as those at base of elytra; coated with gray pubescence not arranged in vittae or other pattern. Sides armed with moderate, acute tubercles, postmediolaterally positioned, tubercles slightly retrorse. Scutellum large, broader than long, broadly truncate at apex, impunctate, clothed with gray pubescence. Elytra broad at base, distinctly tapering apically; together about 2.6 times as long as greatest width (at humeri), covered with gray pubescence, not arranged in patterns or vittae; coarsely punctate, punctures approximately spaced and sized as in pronotum; punctures coarser at base, progressively smaller distally with apical third impunctate; weakly developed basal crests lined with sparse, longer setae present; apices obliquely truncate. Underside densely gray pubescent; prosternal process narrow, broadly expanded apically, at narrowest point one­sixth as wide as procoxal cavities; procoxal cavities closed behind; mesosternal process simple, 2–3 times as wide as prosternal process, about one­third width of mesocoxal cavities. Legs elongate, clavate; finely pubescent, bearing dense coating of gray and golden hairs, more pronounced on apical one­third of tibiae and all tarsi. Abdomen densely pubescent, completely obscuring surface; terminal segment subtruncate, two times as broad as long with apical margin shallowly indented. Length 9.0– 13.5 mm, width 2.8–4.4 mm.

Female. Form similar to male; antennae surpassing elytral apices by about 4 segments; abdomen with terminal segment 1.5 times as broad as long, apical margin truncate and not indented. Length 11.0– 13.2 mm, width 3.9–4.5 mm.

Remarks: This species resembles C. canescens Dillon by the concolorous gray dorsal surface and annulate distal antennal segments. It differs by the weakly­carinate scape with the broadly rounded apical process.

Etymology: This species is named to honor Edmund F. Giesbert, a remarkable, selftaught cerambycid taxonomist who introduced the senior author to the excitement of collecting in the American tropics and with whom he shared many collecting adventures from the late 1970’s until Giesbert’s untimely death in 1999.
