Labrum broadly emarginate. Antennae: Overall length long, antennomeres 10-11 reaching beyond base of pronotum, antennomeres 5-11 elongate. Thorax. Pronotum nearly quadrate, sides evenly rounded in apical 3/4 and then sinuate and straight to base, marginal bead continuous from apex to sinuation then broadening and not delimited medially, hind angle slightly explanate, rounded but nearly right-angled, anterior margin slightly emarginate, anterior angles moderately produced, inner basal impressions linear, slightly divergent and well impressed, outer impression lacking, seta at hind angle well forward of basal margin, about half length of straight portion of margin and nearly as distant from lateral margin. Dorsal surface shiny, microsculpture hardly visible as irregular mesh of microlines at 50x magnification. Elytral striae complete, impunctate, shallowly impressed, except laterally and apically. Stria 6 evanescent near base, not reaching basal margin. Elytra moderately shiny, microsculpture scarcely visible at 50x as stretched mesh of microlines. Metacoxal sulcus straight and ended well before lateral end of coxa. Abdomen. Last abdominal ventrite with narrow, light apical bead. Female tract not studied, male unknown.
Etymology
The specific epithet is carnifex, Latin for the “executioner” and is treated as a noun in the nominative singular standing in apposition.
