<paragraph pageId="0" pageNumber="135">Males (Figs 7, 8, 16). Body length 6.3-7.2 mm; greatest width 3.4-3.9 mm. Form ovate, sides subparallel. Dorsum reddish brown to yellowish brown, shiny, with or without black markings located on head, eye canthus, base of pronotum, outer sides of elytra and scutellum, markings greatly varying in size among individuals. Antennal clubs yellowish brown. Head: Labrum with anterior margin shallowly concave centrally, sides notched, surface coarsely, transversely rugose. Labrum and mandibles visible beyond clypeus when viewed dorsally. Clypeus subtrapezoidal, anterior margin beaded with or without a small convexity at middle, protrusion at basal angle weakly developed, surface coarsely, transversely rugose. Clypeofrontal suture moderately developed. Frons with a small conical convexity at middle of base, tip rounded or weakly bilobed. Eye small, canthus wide, strongly rugose (Fig. 22). Length of antennal clubs shorter than antennal basal segments combined. Thorax: Anterior side of pronotum behind head gradually declivous, midline deeply indented on basal half along with coarse punctures. Surface of pronotum with tiny, secondary punctures sparsely but evenly distributed, large coarse punctures in fossae and both sides of pronotum, sides of basal half of midline and base of pronotum almost impunctate. Fovea vestigial. Scutellum with scattered secondary punctures, slightly longer than wide medially. Elytron: With 7 punctate striae between suture and humeral umbone, punctures coarse, stria 2 interrupted by stria 1 not reaching base, stria 5 terminated in length subequal to stria 2; intervals 1, 3 and 4 more convex and wider than others, interval 2 less convex than others. Legs: Protibia with 9 distinct teeth on outer margin, apical 2 teeth protruding, tip of apical tooth sharp and curved outwardly; metatibia with dorsal apical spur reaching to tip of metatarsomere 2. Male genitalia: Parameres half as long as basal piece, weakly sclerotized, glabrous; surface coarsely punctate (Figs 29, 30). Median lobe trilobite (Figs 35, 36), dorsal sclerite most sclerotized, lip-like in shape and strongly curved downwardly; lateral sclerites short, tightly surrounding dorsal sclerite with apex curved inwardly; supporting sclerites absent. Temones long, elongate with apical part strongly sclerotized and in shape of toothbrush-like. Basal piece with apical portion asymmetrical.</paragraph>
