Holophloeus Jordan, 1928

Type species: Holophloeus irrasus Jordan , 1928

Diagnosis: Medium or large-sized species (ca. 5–11 mm), body elongate, head comparatively long, rostrum longer, subcylindrical, weakly extended apically, with one central longitudinal carina. Antennal scrobes foveiform. Eyes spherical, not emarginate. Antennae of males always extending posterior margin of pronotum, usually reaching the posterior margin of the elytra, sometimes longer or shorter; antennae of females shorter, approximately reaching the posterior margin of the pronotum. Scape and pedicel thick, funicle thin, antennomeres IX–XI not forming a compact club but antennomeres slack and gradually extended. Dorsal transversal carina of pronotum well-developed, often bent in middle, lateral carina short or absent, basal longitudinal carinula of pronotum (= carinula between dorsal transversal carina and posterior margin of pronotum) oblique and forming very shape angle with lateral carina, the carinula often missing. Pronotum with one or two distinct tubercles or tufts of setae, elytra with numerous tubercles or tufts. Mesosternal process small.

The genus Holophloeus differs from the similar genus Meconemus Labram & Imhoff, 1838 (distribution in north, central and south America) mainly by the closed antennal scrobes; Meconemus have the antennal scrobes open posteriorly.
