Type­species. Hinda designata Mulsant, by monotypy.

Redescription. Body oval, convex (Fig. 18); integument black or dark­brown, with yellow spots, or light yellow with brown spots. Head with sexually dimorphic spots. Eyes finely faceted and glabrous, emarginate near antennal insertions (Fig. 1). Antennae short, composed of eleven antennomeres; scape twice as long as wide; pedicel quadrangular; antennomeres 3–8 slender; 9–10 longer; 11 triangular (Fig. 2). Antennal insertion exposed. Clypeus with apical margin almost rectilinear and with lateral margins almost straight (Fig. 1). Labrum apparently rectangular in shape, separated from cephalic capsule by straight, membranous clypeus (Fig. 3). Mandible large and robust, strongly sclerotized, with two incisive teeth, apical and subapical, with pointed median molar on right mandible, squared (less pointed) on left (Fig. 4). Maxillae sclerotized; palpomere 4 securiform with sides that diverge slightly (Fig. 5). Labium having anterior margin of ligula densely covered with small spines, having ventral median portion of ligula with several long bristles; each labial palp with three articles, the basal being shorter, and the last being narrower in the distal region. Mentum cordiform, with rounded apical projections; prementum truncate, with long bristles in median region between palps (Fig. 6). Pronotum transverse, with or without spots; prosternal carinae convergent and terminating together at base of prosternum; prosternal process with nearly parallel sides (Fig. 8). Metendosternite trapezoidal, with straight lateral borders and very shallow V­shaped anterior borders, with smaller angle between proximal tendons; anterior arms with nearly straight apex (Fig. 9). Wings with reduced alar venation; radial sector disappearing and junction of subcosta and radius, terminating separately; first and second anal veins evident but with the empusal veins Ea and Eb vestigial (Fig. 7). Elytra oval with raised humeral callosity and with lateral margin not flattened (Fig. 18); epipleuron with strong excavation to receive apex of the posterior femur (Fig. 10). Femur deeply excavated to receive tibia. Anterior tibia thin, with strongly serrated anterior border and with small foliate projections with marginal microbristles; strongly excavated to receive tarsus (Fig. 11). Second tarsomere triangular in ventral view; tarsal claws appendiculate (Fig. 12). Abdomen with incomplete post­coxal lines on the first visible sternite; six visible segments present in the female, seven in the male (Figs. 13, 14); males of some species with modifications in sixth visible sternite. Male genitalia: Median lobe asymmetrical, except in H. decas and H. designata, widened at base, with apex either straight or truncated. Parameres foliate, articulate in basal region, longer than median lobe, with dense marginal file of long bristles, sometimes with small, sparse internal bristles. Sipho strongly sclerotized, curved, modified apex and variable siphonal capsule. Female genitalia: Spermatheca cylindrical, arched, with rounded cornus, generally with one small ramus; infundibulum present; coxites wide with slender bristles, without stylus.

Type Material. The lectotype (Gordon 1987) was studied, and is located in the Reich Collection of the University Museum of Zoology, Cambridge University, Cambridge, England .

Remarks. The genus Hinda is at present in the tribe Brachiacanthadini together with the genera Brachiacantha Chevrolat in Dejean and Cyra . Hyperaspis and Corystes Mulsant, in the related tribe Hyperaspini, may be compared (Milléo and Almeida, 1999). Hinda is distinguished principally by the anterior tibia with serrated external margins (Fig. 11). It differs from Cyra by the presence of strong excavations in the epipleura (Fig. 10). It differs from Corystes and Hyperaspis in that Hinda has an oval­shaped body, male genitalia with parameres connected directly to the median lobe and female genitalia with an infundibulum and C­shaped spermatheca. The geographic distribution of Hinda includes nearly all of South America.
