"General: Body 1.65 to 1.75 times as long as wide; dorsal surface somewhat shining, without pubescence, most of ventral surface with short, sparse, whitish pubescence. Head: Dull orange to light dull orange, vertex and antennal insertions reddish or darker; front with large, coarse, dense punctures; clypeus sharply delimited at sides, distinctly broadest at apex; antennae of female a little over half as long as body, dull orange throughout to brownish apically. Pronotum: Dull light orange to dull reddish orange, large punctures irregularly darker or reddish; punctation dual, smaller punctures minute, moderate in density, larger punctures large, dense, coarse. Elytra: Dull light orange to dull reddish orange with vague indications of two dark, transverse bands, one behind middle, one before apex. Each elytron with nine rows of fairly large, close punctures, sometimes occasional punctures out of alignment or rows slightly irregular; sixth and seventh rows even throughout to somewhat confused; punctures slightly smaller at apex; inner and outer rows confused at apex and not joining, confused punctures at apex obliterating intervals. Ventral surface: Ventral surface and appendages dull reddish, generally with femora, mesosternum, and base of abdomen dull orange. Anterior margin of prosternum in female somewhat produced ventrally into a rather broad lobe. Fifth abdominal segment at center with a broad, deep pit in female. Pygidium dull orange to dull reddish, densely, coarsely punctate. Length: 4.6 to 5.1 mm" (White, 1968: 60).
"This species is quite similar to ochraceus. In the latter species, elytral striae six and seven are largely to entirely confused, and specimens are known only from Florida. In implacidus, elytral striae six and seven are even to somewhat confused, and specimens are known only from Texas and Louisiana. The specific name refers to the coarse punctation of the pronotum" (White, 1968).
