Leucothyreus

Body length not given. Head small, shorter than pronotum at middle, with deep, large, densely distributed punctures. Clypeus subrectangular, with anterior margin weakly raised. Labrum large, subtriangular, slightly longer than ventral face of clypeus; mentum with a transverse, moderate setal brush bearing thick, white setae. Antennae with 10 antennomeres, club elongate, slightly shorter than antennomeres 2–7 combined. Pronotum medially wider than head, with lateral margins evenly curved; lateral punctures with decumbent, scale-like, white setae. Scutellar shield with sparse, deep, setigerous punctures bearing thick, decumbent, white setae. Elytra moderately covered with deep, transversely fusiform punctures bearing white, transversely decumbent scale-like setae. Thoracic venter and abdomen densely covered with decumbent, scale-like, white setae. Metaventrite with postcoxal line medially effaced, with a row of thinner, hair-like setae. Protarsomeres I–V dorsoventrally flattened and densely setose internally. Meso- and metatarsomeres I–IV slightly flattened dorsoventrally and densely setose internally; meso- and metatarsomere V cylindrical, sparsely setose internally, longer than respective tarsomeres II–IV combined, with a short, acute internobasal tooth. Meso- and metatarsal empodium with two long, apically bifurcate setae. Ventrite 1 medially projected, with posterior postcoxal line extending to posterior margin of ventrite 1 and bearing dense, hair-like setae. Coloration of head, pronotum, and scutellar shield reddish brown, with weak to strong metallic-green reflections; venter reddish brown. Females similar to males but body more robust, pronotum sparsely setose, protibial outer teeth stronger, pro- and mesotarsomeres moderately setose and narrower, posterior margin of ventrite 6 evenly rounded.
