Bocainella gen. nov.

Type species. Bocainella minima , new species.

Description. Frons large, transverse. Antennal tubercles prominent and distant. Genae rounded. Eyes coarsely faceted, upper lobe absent. Antennae 11-segmented; scape short and cylindrical, about 1/3 shorter than segment 3; segments 3-4 filiform; segments 5-11 gradually shorter to the apex. Prothorax as long as wide, rounded at sides. Pronotum strongly convex. Anterior coxal cavities closed behind and intermediate open to epimera. Metasternum short, as long as mesosternum. Scutellum very small, triangular. Elytra fused, convex, about 2 times as long as prothorax; apex conjointly rounded. Humeri not projected. Hind legs about 1/ 3 longer than forelegs. Femora subclavate; first segment of metatarsi as long as second segment. First urosternite 1/3 longer than second; second to fourth subequal in length; fifth slightly longer than fourth, rounded at distal margin.

Etymology. The genus epithet refers to the type locality, Serra da Bocaina in the state of São Paulo, Brazil.

Remarks. Bocainella gen. nov. is similar to Cupeyalia , Maisi , Nanilla , and Ipochus , sharing the rounded sides of the prothorax; all other Western Hemisphere genera have tubercles or spines at the sides of the prothorax. Bocainella differs from these four genera by the combination of: the lack of the superior ocular lobe; antennae 11-segmented; elytral surface with tubercles and spines; and femora subclavate. Cupeyalia differs from Bocainella in the presence of the superior ocular lobe, the antennae 7-segmented, and the elytral surface not tuberculate. Maisi has the superior ocular lobe, elytra without tubercles or spines, and femora clavate. Nanilla has the superior ocular lobe, elytra with tubercles but without spines, and femora linear. Ipochus has the superior ocular lobe, elytra without tubercles or spines, and femora clavate. Only one monotypic genus, Plaumanniella ( Fig. 3 ), occurs in Brazil; it differs from Bocainella , in addition to the presence of tubercles at the sides of the prothorax, in having long and erect hairs on the body, and the elytral surface without tubercles or spines.
