Male. Length 2.72–3.32 mm, width 2.32–2.98 mm. Body elongate-oval with sparse yellowish pubescence. General color yellowish brown, pronotum with central black spot; scutellum black or yellow. Elytra yellowish brown, with quadrangular black spot in middle of elytra and two on lateral margin of each elytron, one elongated below humeral callus, and another transversely elongated spot on apex ( Figs 1 A–D). Antennae, mouthparts, hypomera, epipleura and legs yellowish brown, femur sometimes dark brown ( Fig. 1 B). Meso- and metasternum and anterior half of first abdominal ventrite black.

Genitalia symmetrical; basal lobe shorter than parameres, acuminate at apex ( Fig. 1 E). Parameres elongated, slightly widened, with long bristles throughout their length, these bristles shorter at base ( Fig. 1 F). Sipho with emarginate apex and elongated siphonal capsule ( Fig. 1 G).

Female. Length 2.80–4.00 mm, width 2.24–3.08 mm. Coxites longer than wide, subtriangular; apex mammilliform, with long bristles ( Fig. 1 H). Spermatheca C-shaped, elongated with rounded apex ( Fig. 1 I).

Geographical distribution. Brazil (CE, BA, MG, RJ, SP, PR, SC, RS).

Remarks. Chnoodes brasiliensis ( Fig. 1 ) is most similar to C. pentagona ( Fig. 4 ), but is clearly distinguished by the arrangement of spots on the elytra, and the pattern of the genitalia.
