Distribution. Costa Rica, Panama, Guyana, Brazil (Stebnicka 2009), and Colombia (Pardo- Locarno and Schoolmeesters 2019), to which we add Trinidad, French Guiana, Suriname, and Bolivia.

Diagnosis. Batesiana tuberculata is distinguished from the new species by the smaller body size, smaller, shallower, and less dense dorsal punctation, moderately gibbous clypeus, mentum simply swollen, posterior angles of pronotum 90°, prosternal process triangular posteriorly, metafemoral posteri- or line complete, and protibial teeth equidistant from each other.

Description. (Updated from Stebnicka 2009) Length 5.3–6.6 mm. Body piceous black, moderately glossy ( Figs. 6–8 ). Head broad, strongly deflexed, everywhere coarsely, closely punctate; punctures moderate, not foveate over most of central surface ( Fig. 9 ); clypeal margin nearly truncate, with distinct subelliptical, inflexed clypeopleuron in medial third; medial clypeal gibbosity moderately prominent, obtusely (> 90°) angled in lateral view; mentum with indistinct medial longitudinal swelling ( Fig. 10 ). Pronotal surface with moderate, close, nonfoveate punctures; lateral area scabrous, swollen along margin with shallow, contiguous punctures, punctures evident in medial scabrous area; lateral pronotal explanations with posterior angles 90°, not projecting posteriorly. Scutellar shield triangular, flat. Elytra ovate, strongly convex, humeri dentate; base with sharply defined marginal bead; striae and strial punctures fine, intervals with tubercles and swellings, irregular in shape and spacing. Ventral sclerites alutaceous. Prosternal process behind coxae with carina encompassing broad triangular area that is flattened medially; mesoventrite declivous, transversely concave medially; mesocoxae widely separated, intercoxal carina wide, glossy; metaventral disc convex, punctate, lateral area alutaceous, smooth. Abdominal sternites convex, fused, fluting along sutures inconspicuous, surface irregularly punctate medially and along posterior margin from side to side, laterally alutaceous anteriorly, often slightly wrinkled; disc of pygidium broad, not deeply eroded. All femora punctate; posterior lines of meso- and metafemora complete; protibia short, with 3 minute lateral teeth, equidistant; meso- and metatibiae with longitudinal lines and close golden setae, apical spurs very short, spine-like; tarsi short, robust, tarsomeres triangular, covered with close golden setae; claws minute. External sexual differences slight: male penultimate abdominal ventrite shorter than in female, male disc of pygidium broader. Male genitalia simple, short, narrowing posteriorly, rounded in lateral view ( Figs. 11–12 ).
