Head without microsculpture or punctures, sparsely pubescent on vertex; tempora slightly longer than half length of eyes; vertex moderately tumid, posterior supraorbital setae distant from eyes, seta insertions slightly humped, but not horn-like; labrum slightly widened to apex, apical margin deeply emarginate. Pronotum slightly wider than head, widest slightly before middle; ratio PW/PL 1.45; pronotal base briefly but distinctly lobed; front angles wide; lateral margins strongly expanded in middle, completely rounded, slightly sinuate before hind angles; hind angles subrectangular, hardly projected; disc slightly convex, microsculpture indistinct; lateral explanate areas wide and even; basal foveae shallow; disc nearly impunctate, with a few punctures along median line and in basal foveae; disc with long setae except area along median line, some setae distributed to middle of lateral explanate areas; lateral margins with long accessory setae through their full lengths, sparser after middle; median line distinct, nearly reaching basal and apical margins; disc not rugose. Elytra wider than pronotum, shoulders not narrowed, hind wings well developed; elytral lateral borders narrow, not reflexed up; striae very shallow, finely punctate; scutellary intervals with three large pores (basal pores); intervals flat, without microsculpture, odd intervals with secondary pores, more abundant on 7th interval; primary pores indistinct among secondary pores, 3rd and 5th intervals with some larger pores distinguishable; setae not present along striae; umbilical series of 9th interval composed of 15 pores; disc without distinct depression; lateral margins slightly depressed at basal third; 7th and 8th intervals slightly tumid near apex; elytral lateral margins with dense and fine setae; epipleura pubescent. Ventral side. Prosternum with long pubescence, proepisterna glabrous; mesosternum nearly glabrous; abdomen hairy. Male genitalia with median lobe of aedeagus straight and flat, gently expanded to apex; dorsal side slightly pubescent subapically; left lateral margin slightly curved in middle; apical orifice opened apically; apical lamella placed on right side, short and rounded, distinctly wider than length in dorsal view; internal sac with main flagellum thick and slightly corkscrewed, distinctly grooved ventrally, nearly reaching apical orifice; trumpet-form expansion strongly expanded, nearly half length of main flagellum (Fig. 78).
