Redescription. Length 4.0-5.0 mm, oval-elongate, moderately convex, subshiny, nearly glabrous. Yellowish-brown; head anteriorly and pronotum disc brownish; elytra with juxtasutural interstria, base of fifth interstria and preapical declivity brownish, apical declivity including an oblique oval yellowish spot ( Fig. 44 View Figure 43-56 ); sometimes elytra almost entirely dirty yellowish ( Fig. 46 View Figure 43-56 ) or almost entirely dark-brownish ( Fig 45 View Figure 43-56 ). Head with epistome somewhat convex medially, superficially microreticulate, regularly and distinctly punctured; punctation denser and coarser laterally; clypeus slightly sinuate at middle, round at sides, bordered, edge shortly bristled; genae round, slightly auriculate, shortly ciliate, feebly protruding from the eyes; frontal suture finely impressed; front regularly and rather coarsely punctured. Pronotum transverse, moderately convex, distinctly, regularly and rather densely punctured; sides slightly sinuate inwardly before hind angles, finely bordered, edge glabrous; hind angles obliquely truncate, the truncature not inwardly sinuate; base bisinuate. Scutellum elongate with curved sides, coarsely but rather sparsely punctured. Elytra almost subparallel-sided, convex, minutely denticulate at shoulder, finely striate; striae feebly crenulate; interstriae almost flat, superficially microreticulate, finely and irregularly punctured, sparsely shortly pubescent on preapical declivity. Hind tibiae upper spur shorter than first tarsal segment; latter slightly longer than following three segments combined. Male: fore tibiae spur abruptly downward curved; pronotum relatively more transverse and less convex; metasternal plate distinctly excavate; aedeagus Fig. 48-49 View Figure 43-56 . Female: fore tibiae spur almost straight; pronotum relatively narrower frontward and more convex; metasternal plate almost flat.
