Description. Measurements (in mm): total length 3.3-3.4; maximum elytral width 2.2-2.3 Body convex ( Figs. 1-2 ). Cuticle black, matt. Head finely, but clearly punctate, without setae. Eyes small, visible from above. Antennae brown, with eleven antennomeres, antennal club with three antennomeres, with yellow setae. Mentum with small punctures, with V-shaped groove (Fig. a), with long yellow setae. Pronotum as finely punctate as head; without setae. Pronotal anterior angle with very indistinct small groove. Scutellum triangular, finely punctate. Elytra without setae, each elytron with 11 striae produced by visible punctures; small punctures forming quadrangular-hexagonal patterns with one central puncture. Mesosternum finely and regularly punctate. Metasternum without longitudinal carina, punctures very large on lateral margins.

Differential diagnosis. The new species belongs to the testudinum group and according to the groove as in similar species dybasi, testudinum (U-shaped groove) but it differs from them by the structure of the V-shaped grooveof the mentum, and structure of male genitalia; from dybasi, it differs by the quadrangular-hexagonal pattern of elytral punctures.

Etymology. Toponymic, named according to the country, Brazil.
