Head with patch of whitish to yellow or light brown scales on middle of vertex, surface with dense punctures, somewhat irregular; frons concave. Pronotum in lateral view moderately convex; in dorsal view with longitudinal carina near middle, flanks with upper half rugose, lower half with deep and long punctures. Elytra with basal margin sinuate ( Figure 4 View FIGURES 1–11. 1–5 ); surface with punctures moderate, deep; tubercles distribution as follows: I2 with elongate tubercle near base of declivity; I3 with four tubercles, elongate subbasal tubercle, round tubercle at about midlength, two small elongate tubercles on declivity, one near middle, other near declivity apex; I4 with two tubercles, elongate, small, between tubercles of I3, other tubercle high, rounded at base of declivity, a little beyond I2 (this slightly higher than others); I5 with three elongate tubercles, first subbasal, second near midlength, both tubercles more or less the same size and shape as those on I 3 in same position and third tubercle little forward of base of declivity, much smaller than previous ones and that of neighboring tubercles, I6 with two elongate tubercles, small one located between tubercles on I5, and second near elytral declivity, I7 with two tubercles, one subbasal and round, other near middle of elytra, elongate, very small; tubercle on I2 on elytral declivity slightly smaller than that on I 4 in the same position. Metasternal tooth present. Male with ventrite 1 concave; ventrite 5 convex in middle, female with two apical lateral impressions, occasionally ventrite 2 depressed medially. Hind tibia with outer margin excavate, inner margin curved in apical ¼.
