Lophobothea gen. nov.

Type-species: Carneades reticulata Bates, 1881

Description. Head with vertical frons longer than wide. Antennal tubercles not projected. Eyes finely faceted, upper lobes separated by greatest width of a lobe; lower lobes about as tall as one-half the gena below it. Mandibles moderately short, apices unidentate. Antennae with 11 antennomeres; scape slightly and gradually enlarged at distal third, antennomere 3 slightly longer than scape, antennomeres 3–10 with distal third slightly widened; ventral surface of antennomeres without setae.

Prothorax with minute lateral tubercle at beginning of posterior third, sides constricted. Pronotum with feebly obtuse elevation at each side of midline in anterior half; surface very finely punctate. Prosternal process about half width of procoxal cavity. Mesosternal process as wide as mesocoxa. Metasternum flattened, covered with sparse pubescence. Scutellum rounded at apex. Elytra with sides parallel from base to apex, humeri rounded, moderately projected, each elytron with three latero-longitudinal carinae, two medial carinae parallel from humeri to beginning of distal third, and lateralmost carina parallel to marginal border, from subhumeral region to external spine. Apex of elytra with obtuse projection at sutural apex, marginal angle projected in acute spine. Femora pedunculate, expanded at distal half. Tibiae approximately equal in length to femora.

Abdomen with five visible ventrites.

Etymology. Greek, lophos, crest, carina, plus bothea from Colobothea .

Remarks. Lophobothea gen. nov. differs from Carneades in having the sides of the prothorax minutely tuberculate, constricted in the posterior third; the elytra with an acute lateral carina from the humeri to the beginning of the distal third; and the apex of the elytra with the marginal angle projected in an acute spine. In Carneades , the sides of the prothorax lack tubercles or a constriction, and diverge gradually from the anterior to posterior margins; the lateralmost carina of the elytra is reduced or absent; and the apex of the elytra is notched and the marginal angle is not projected in a spine.

Lophobothea gen. nov. differs from Nodubothea in the absence of a median tubercle on the sides of the prothorax, and in the elytra without a centro-basal crest; in Nodubothea the sides of the prothorax are obtusely tuberculate and the elytra has a prominent centro-basal crest.
