Rhomboid-ovate, black; somewhat thickly clothed with small, narrow, blackish or fuscous scales intermixed with a few longer setiform white scales, the scales on the elytra seriately arranged and the white ones mostly confined to the alternate interstices; the vestiture of the legs and under surface rather sparse, fine, and white. Head finely punctate, transversely grooved between the eyes; rostrum very stout, abruptly arched from the base, not longer than the head and prothorax, striate and thickly punctate, smoother at the tip in the ♀, the antennae inserted at the middle, the outer joints of the funiculus strongly transverse, the club short, ovate. Prothorax transverse, arcuately narrowing from the base, constricted in front; coarsely, densely punctate. Elytra gradually narrowing from the base, broadly rounded at the apex, somewhat flattened on the disc; narrowly striate, the interstices rugulosely punctate. Beneath densely punctate. Prosternum with a smooth, bare, flattened, triangular depression, limited on each side by the oblique ridge, the depression widening forwards and confluent with the subapical foveae. Anterior coxae separated by half their own width. Legs rugosely punctate; intermediate and posterior femora sulcate beneath from near the base to the apex.

Length: 2(2/5)- 2(4/5) mm, Breadth: 1(1/3)-1(1/2) mm.

Hab. Guatemala, Capetillo and Guatemala city (Champion); Nicaragua, Managua (coll. Solari)

Eight specimens from Guatemala and three from Nicuragua. The fine dark vestiture of the elytra is arranged in one or two rows down each interstice, the longer white scales being mostly placed along the alternate ones. Less convex than Zygobaris tristicula, the rostrum short, stout, and abruptly arcuate, the prosternal sulcus widening forwards to the transverse subapical groove, which is impressed with two foveae.
