Head small, with small, hemispherically prominent eyes, frontal interocular distance 2.0 times maximum diameter; antennae flabellate, long, reaching to three quarters of elytral length if inclined, antennomere 3 with lamella 3.9 times longer than stem of antennomere, lamella attached close to middle part of antennomere ( Fig. 16 ). Pronotum transverse, 1.5 times wider than long at midline, lateral margins elevated, frontal margin projected anteriorly, frontal angles widely rounded, lateral margins slightly concave, posterior angles projected, all carinae well-developed ( Fig. 31 ). Elytra flat, parallel-sided, transverse costae well-developed, regular, elytral areoles slightly transverse ( Fig. 48 ). Phallus slender, parallel-sided, with gradually acuminate apical part and projected slender apex ( Figs. 75–76 ). Measurements. BL 15.1 mm , PL 1.66 mm , PW 2.48 mm , WH 1.56 mm , Edist 0.95 mm , Ediam 0.48 mm , LE 13.0 mm, antennomere 3: stem 0.85 mm , lamella 3.3 mm . Distribution.
