Redescription. Eyes coarsely faceted. Labrum covered by short brown pilosity and long brown decumbent hairs. Lower ocular lobes ovate. Antennal tubercles feebly prominent; directed posteriorly. Antennae filiform, unarmed, sexually dimorphic, long, exceeding elytral apices at antennomere VII in males and VIII in females, with short erect brown setae throughout. Prothorax distinctly transverse; sides of prothorax with median acute tubercles directed slightly dorsally.
Pronotum with two median rhomboid tubercles on disk; pronotum elevated between the tubercles; a row of coarse punctures on posterior and anterior margins; punctures between the tubercles. Intercoxal process of prosternum about one-third as wide as procoxa, narrow, elevated on lateral margins. Procoxal cavities closed behind. Mesocoxal cavities open; mesepisternum triangular with base rounded; metepisternum narrow. Metasternum planar; with long erect hairs. Scutellum truncated at apex and apical margins slightly elevated.
Elytra slightly convex, 1.6 x as long as prothorax, gradually narrowing toward apices; with cristae at base; coarse punctures only on basal one-third. Black, semidecumbent setae more concentrated in central region, and white, erect setae in lateral region. Humeri rounded and slightly projected anteriorly. Metalegs slightly longer than prolegs; pro- and mesocoxae rounded, the former much more prominent; tibiae and femora subequal in length with long white erect hairs. Femora pedunculate-clavate. Tibiae linear; metatibial spurs narrow, with inner spur about twice as long as outer spur; tibiae and femora subequal in length. Urosternites I–IV gradually narrowing to apex; V urosternite twice as wide as preceding urosternite; females with narrow longitudinal glabrous and smooth band on basal one-third; in males, entirely clothed by pilosity.
Remarks. Lane (1943) considered Zikanita (Figs. 2, 3, 4) similar to Cosmotomidius (Machado & Monné, 2009 Figs. 2, 5) the former differing by the scape and antennomere IV subequal in length and the mesosternal process tuberculate. Zikanita is similar to Cosmotomidius by the presence of dense long hairs over the body, the pronotum with median tubercles, sides of prothorax with tubercles and the elytra with black suberect setae. Zikanita differs from Cosmotomidius in total length, which reaches almost 20 mm, the elytra are 1.6 x wider than the prothorax at the base and the antennae are long exceeding the elytral apices at antennomere VII in males and VIII in females. In Cosmotomidius (Machado & Monné, 2009 Figs. 2, 5) the total length does not exceed 14 mm, the elytra are 1.4 x wider than the prothorax at the base and the antennae exceed the elytral apices at antennomere VIII or IX in males and IX or X in females.
