TL 5.6–7.9 mm; GEW 2.5–3.5 mm. Body elongate oval, relatively narrow, moderately tapered posteriorly (Fig. 12), moderately convex dorsally (Fig. 24); entire body piceous to nearly black, except for antennomeres 1–4 and tip of antennomere 11 somewhat lighter in color, very dark rufous.
Head with uniformly spaced, relatively coarse punctation; eyes (Fig. 36) deeply emarginated around antennal insertions, separated dorsally by distance approximately equal to maximum width of first antennomere; antennomeres 5–10 (Fig. 36) distinctly widened in both sexes, and with different microsculpturing than antennomeres 1–4; antennomeres 7–10 subquadrate, wider than long; male with antennomeres 5–11 flattened on ventral side, ventral surface of antennomeres 5–10 with short, slender “accessory” setae (sensilla); distal maxillary palpomere not widened distally, subparallel-sided, apex slightly oblique.
Pronotum with uniform, shallow punctation and short, apressed brownish setae; posterior margin with two clusters of coarser punctures, equidistant between middle and lateral margins; posterior margin of pronotum bisinuate, inner sinuation deeper than outer; bead distinct along lateral, anterior, and posterior margins, somewhat obscured on middle lobe of posterior margin; prothoracic episternal suture present; surface of proepisterna smooth, regularly punctuate, without coarse or rugose macrosculpture; prosternal process (Fig. 48) moderately elongate, not attaining posterior margin of procoxae, apex moderately broadly rounded; mesosternum short, distinctly keeled.
Elytra elongate, slightly convex; punctation of two types: coarse punctures forming 10 striae on each elytron; other punctures finer, setose, setae uniformly distributed, decumbent; epipleuron distinct, narrowed posteriorly, but traceable to elytral apex; flight wings full, functional, membrane darkly pigmented.
Legs all relatively similar in shape; metathoracic legs more elongate than meso- or prothoracic legs; all tarsi cylindrical, without ventral lobes; outer surfaces of meso- and metatibiae with numerous, oblique ridges; tibial spurs distinct, paired; tarsal claws slender, without basal tooth or expansion; male profemur with small, ovate, setiferous pit on ventral surface, approximately ¼ to 1/3 distance from base of femur.
Abdominal ventrites with uniform, relatively coarse punctation, setae decumbent; male genitalia darkly pigmented (Fig. 62) with apical and basal piece of tegmen subequal in length; struts on median lobe elongate, relatively narrow, inner margins V-shaped; sternite 9 basally Y-shaped, with long stem.
