DESCRIPTION: Size: Length 4.5–5.2 mm; width 2.0– 2.6 mm. Integument: Black, except legs, elytra piceous and apex of antenna testaceous. Vestiture: Head, prothorax, elytra, and protibia vested predominantly with dark setae, pterothorax, femora, and mesometatibiae vested predominantly with pale setae; tarsi vested with dark setae, elytral middiscal setal tuft comprised of one patch whose setae are directed anteriorly. Head: Width across eyes feebly narrower than width across pronotum (32:35) finely punctate; interocular depressions and frontal umbo shallow; eyes subspherical, moderately convex; antenna as in figure 77. Thorax: Pronotum as long as wide (35:35), narrower than width of elytra across humeri (35:40), anterior transverse depression moderately indicated; elytral depth at humerus 10, greatest depth in posterior half 20, humeral umbo prominent. Abdomen: Male pygidium with posterior margin narrowed, feebly truncate, tegmen as in figure 211.

ETYMOLOGY: The trivial name anticus (in front) is a Latin adjective used here to refer to the anterior orientation of the setae of the elytral middiscal tuft.
