( Figs. 2, 4 , 12, 15 , 17 )

Description. Total length 5.5–6.1 mm, standard length 5.4–5.9 mm (n=2). Integument reddish to brown; basic vestiture of small, yellowish to brown scales; moderately dense to imbricate, white to pale yellow scales in compound pattern on pronotum, elytra, mesepisternum, metasternum and ventrites ( Figs. 2, 4 ). Rostrum 0.75– 0.82× as long as pronotum, middle section more curved, portion distal to antennal insertion 0.39–0.43× as long as rostrum. Pronotum 1.04–1.05× longer than wide, sides subparallel in basal half, constricted and tubulate in front, front projected. Elytra 1.52–1.56× longer than wide, humeri 1.43–1.49× wider than pronotum; striae subtle and narrower than strial punctures; interstria 3 not swollen on disk, preapical callus weak. Legs slender, femora clavate and with ventral tooth, tibia with ventral margin nearly straight, tarsal claws subconnate at base. Male with ventrite 5 depressed; apex of aedeagus subtriangular, fused medially, lateral portions membranous ( Fig. 12 ); internal sac with basal sclerite flagelliform ( Fig. 15 ), approximately as long as apodemes.
