Redescription. Integument reddish-brown to reddish-black; covered with short, deeper, moderately sparse to dense setae ( Figs 14–16 ). Rostrum short and wide, 1.4 times its basal width, apex depressed; punctation shallow and sparse dorsally, lateral punctation moderately deep and sparse, with anastomosing punctures forming longitudinal wrinkles. Scrobes ventrally separated by an obsolete longitudinal carina. Antennae with a scape shorter than funicle; inserted medially in females, and near the apex of rostrum in males. Mouthparts: mandibles bi-toothed, teeth round and contiguous ( Fig. 17 ). Palpifer and 1 st article of maxillary palp as long as wide, 2 nd article transverse; with 2–3 setae, stipes glabrous; lacinia with eight teeth ( Fig. 19 ); prementum transverse, sides straight, parallel, anterior margin round; a pair of posterior setae near basal margin; labial palps elongate, symmetrical, laterally with two pairs of basal setae ( Fig. 18 ). Interocular space 1.4 times the apical width of scape. Prothorax conical, wider posteriorly, sides converging toward anterior margin; punctation deeper and dense, with wrinkles on the lateral margins; disk with a smooth, median longitudinal line; laterally with 2–3 developed tubercles ( Fig. 20 ). Elytra 1.2 times longer than their humeral width; scutellar shield cordiform ( Fig. 16 ); striae with deeper punctures, granules on anterior margin; interstriae 1, 2 and 4 near the base convex, forming longitudinal tubercles; remaining interstriae transversely convex, apical callus round, developed ( Fig. 16 ). Legs: punctation deep, dense, moderately wrinkled. Femora unarmed. Foretibiae slightly crenulated; median ventral tooth short to developed, acute to truncate. Male genitalia: median lobe as long as basal apodemes; convex dorsally, curved in lateral view; apex round ( Figs 23, 24 ). Tegmen with dorsal lobes subequal in length to manubrium ( Fig. 25 ). Spiculum gastrale long and narrow curved at apex ( Fig. 26 ). Female: abdominal tergite 8 transverse, trapezoidal, sides parallel basally, converging on apical 2/3; apical margin crenulated with median distal notch; with a moderate number of setae; dorsally with thin punctation covered with moderately long setae ( Fig. 27 ). Abdominal sternite 8 with ventral spicule wide, straight, elongate, longer than apical arms, the latter parallel and converging toward the apex; apex with long and dense setae ( Fig. 28 ). Coxites cylindrical, elongate, without setae. Styles cylindrical, distinct, apex covered with short and dense setae. Bursa copulatrix membranous, without sclerites. Spermatheca curved; ramus subequal to collum. Spermatecal gland membranous, larger than spermatheca; spermathecal duct as long as bursa copulatrix, introduced into the bursa copulatrix base ( Fig. 29 ).

Sexual dimorphism. Foretibiae of males with premucro obsolete; mucro and premucro subequal in females.

Biology and host plants. Bondar (1928a, 1928b, 1930a, 1930b), in a study of the biology of Sternechus tuberculatus (misidentified as S. uncipennis ), reported that the adults have nocturnal habits, spending the day attached to the leaves of Canavalia sp. and feeding on the green pods during the night. Bleiler et al. (1988) and Rosenthal (1986) identified the species as Canavalia brasiliensis . This species leaves round wounds on the dorsal margin of the pods when feeding. The pods are also used as a substrate for oviposition.
