Redescription. Body length: PEL: 2.00– 2.90 mm; APW: 0.75–1.10 mm; PPW: 1.50–2.00 mm; EL: 1.20–1.80 mm; EW: 1.65–2.50 mm.
Body ( Figs. 282–283 View Figs ) rectangular oval, dorsal surface convex, ventral surface flattened, cuticle shining, entirely black, often with large red macula on each elytron, legs, mouthparts and antenna reddish-brown, antennal club black.
Antennal scape ( Fig. 285 View Figs ) with few short setae; club round, without visible articulation, entire surface with thick short sensilla, intermingled with sparse longer erect sensilla; sensory structures of antennal club ( Fig. 18 View Figs ) in form of stipe-shaped vesicle situated under a large circular sensory area on internal distal margin of the ventral side of antennal club.
Mouthparts. Mandibles ( Fig. 86 View Figs ) with carinate outer margin, strongly curved inwardly, mandibular apex acutely pointed; sub-apical tooth on left mandible large, almost perpendicular; labral disc ( Fig. 51 View Figs ) very sparsely punctate, almost smooth, convex medially; labral pits shallow, each with two well-sclerotized long setae; terminal labial palpomere elongated, its width about one-third its length; mentum rectangular, anterior angles produced, anterior margin ( Fig. 115 View Figs ) deeply emarginate; with two short setae, lateral margins and disc of mentum glabrous; cardo of maxilla on lateral margin with few minute setae; stipes triangular, with three longer setae; terminal maxillary palpomere elongated, its width about one-third its length, about three times as long as penultimate.
Clypeus ( Fig. 285 View Figs ) without elevated anterior margin, flattened, sub-quadrate, smooth, lateral margins rounded; frontal stria well impressed, carinate, almost straight, supraorbital and postorbital striae well impressed; frontal disc entirely smooth; eyes convex, visible from above.
Pronotal sides ( Fig. 282 View Figs ) moderately narrowing anteriorly, apical angles obtuse, anterior incision for head shallow, almost straight in middle; marginal pronotal stria complete; pro- notal disc entirely smooth, only with a row of fine scattered punctures along pronotal base in antescutellar area; pronotal hypomeron glabrous; scutellum conspicuous.
Elytral epipleuron smooth on basal half, apical half with shallow depressions; marginal epipleural stria complete; marginal elytral stria bisinuate, well impressed, carinate, continued as weakened but complete apical elytral stria. Humeral elytral stria weakly impressed on basal third; outer and inner subhumeral striae absent; first dorsal elytral stria rudimentary, second and third dorsal elytral striae well impressed, thin, not reaching elytral half apically, fourth dorsal elytral stria absent (at times confined to basal region, represented by a short arch); sutural elytral stria well-impressed, abbreviated on basal third, apically connected with apical elytral stria; entire elytral disc smooth.
Propygidium with sparse round punctures, interspaces finely imbricate; punctation of pygidium even sparser and finer than that of propygidium, becoming smooth apically.
Anterior margin of median portion of prosternum ( Fig. 287 View Figs ) obtuse-angulate, marginal prosternal stria absent; pre-apical foveae absent; prosternal process strongly compressed, knife-like, dorso-laterally finely substrigulate; carinal prosternal striae extremely short, present only on prosternal apophysis; lateral prosternal striae well impressed, strongly convergent anteriorly, apically united, attaining middle of prosternal process; outer-lateral costa reaches prosternal process, its basal margin not distinctly elevated.
Anterior margin of mesoventrite deeply emarginate medially; discal marginal mesoventral stria deeply impressed, complete; mesoventral disc smooth, about as long as broad; mesometaventral sutural stria almost straight; intercoxal disc of metaventrite flat, smooth; lateral metaventral stria well impressed, carinate, curved outwardly, not reaching hind coxa; lateral disc of metaventrite ( Fig. 288 View Figs ) slightly concave, with round punctures separated by about their own diameter fringed with short yellow setae; interspaces finely imbricate; metepisternum + fused metepimeron ( Fig. 288 View Figs ) with even coarser and denser punctation, on metepisternum punctures fringed with very short yellow setae, on fused metepimeron punctures asetose.
Intercoxal disc of first abdominal sternite with medio-basal depression, completely striate laterally; almost entirely smooth, in postero-lateral corners with scattered fine punctures.
Protibia ( Figs. 289–290 View Figs ) on outer margin with three apical low teeth topped with long denticles, followed by seven prominent slender denticles, diminishing in size in proximal direction; protarsal groove deep; setae of outer row sparse, long; anterior protibial stria costiform, complete; setae of median row minuscule; protibial spur growing out from apical margin, well developed, bent; near tarsal insertion single long tarsal denticle present; posterior surface ( Fig. 290 View Figs ) with numerous denticles, interspaces between them smooth; border between outer and median part of posterior surface unclear; posterior protibial stria fine, with sparse microscopic setae; setae of inner margin short, strongly sclerotized, confined to apical fourth.
Mesotibia somewhat dilated and apically slightly thickened, outer margin with at least three dense rows of short denticles, continued on anterior surface ( Fig. 284 View Figs ); posterior mesotibial stria almost complete; setae of outer row strongly sclerotized, almost as long as denticles itself; setae of median row double, much shorter, finer and sparser; mesotibial spur prominent, long on apical margin surrounded by numerous short dense denticles; anterior mesotibial stria shortened apically; each tarsomere ventrally with two strongly sclerotized long setae; claws of apical tarsomere bent, longer than half its length; metatibia slightly dilated and thickened, in all aspects similar to mesotibia, but rows of denticles on anterior surface even denser; meso- and metafemora thickened.
Male genitalia. Eighth sternite ( Figs. 291–292 View Figs ) longitudinally fused medially, apically with row of sparse short setae and broad velum with numerous tiny setae; eighth tergite and eighth sternite not fused laterally ( Fig. 293 View Figs ). Morphology of 9 th tergite ( Figs. 294–295 View Figs ) typical for the subfamily; spiculum gastrale expanded on caudal end, but only slightly so on the apical end. Basal piece of aedeagus ( Figs. 297–298 View Figs ) short, ratio of its length: length of parameres 1: 4; parameres fused along their basal two-thirds; aedeagus gently curved ventrad ( Fig. 298 View Figs ).
