Redescription. Body length: PEL: 1.375 –1.875 mm; APW: 0.625–0.75 mm; PPW: 1.0– 1.375 mm; EL: 0.875 –1.125 mm; EW: 1.125–1.5 mm.

Body (Fig. 215) shortly oval, convex, without metallic luster; cuticle brown to dark brown, legs, antennae and mouthparts rufous. Antennal scape (Fig. 218) slightly thickened, with several short setae; club (Fig. 216) without visible articulation, entirely covered with short sensilla intermingled with sparse longer sensilla; sensory structures of antennal club not examined.

Mouthparts. Mandibles stout; mentum rectangular, posterior corners produced, with tiny notch in middle of anterior margin (Fig. 111); anterior margin in anterolateral corners with four moderately long setae, lateral margins with single row of much shorter ramose setae; disc of mentum glabrous. Cardo of maxilla with several short ramose setae on lateral margin; stipes triangular, with four much longer setae; terminal maxillary and labial palpomeres somewhat thickened, their width less than half their respective lengths; other parts of mouth not examined.

Clypeus and frontal disc rugulose-lacunose (Fig. 218); frontal stria widely interrupted anteriorly continued as complete elevated supraorbital stria posteriorly connected with complete occipital stria; eyes flattened, almost invisible from above.

Pronotum (Fig. 215) gently convergent apically; apical angles not produced; anterior emargination for head shallow; marginal pronotal stria complete; disc entirely with punctation, punctures becoming coarser and denser laterally; pronotal hypomeron with short sparse amber setae.

Elytral epipleura with a row of deep punctures; marginal epipleural stria weakly impressed, shortened apically and basally; marginal elytral stria complete, deeply impressed and in punctures, continued as complete apical elytral stria. Elytra with four dorsal elytral striae 1–4, well impressed, in round punctures; all striae about the same length, reaching about three-fourths of elytral length apically; humeral elytral stria well impressed on basal third; inner subhumeral stria short, present as medial fragment; fourth dorsal elytral stria basally connected with complete sutural elytral stria, that is linked with apical elytral stria; between sutural elytral stria and elytral suture a row of tiny punctures present. Entire elytral disc with round, scattered punctation, punctures separated by about 2–4 times their diameter, punctation not becoming denser apically.

Propygidium short, partly covered by elytra, with two rows of coarse and dense punctures; pygidium with dense regular punctures becoming finer apically; interspaces with microsculpture.

Anterior margin of median portion of prosternum (Fig. 221) rounded; marginal prosternal stria present laterally and as apical fragment; pre-apical foveae small; prosternal process narrow, interspace between carinal prosternal striae with scattered microscopic punctation; surface between carinal and lateral prosternal striae with several large coarse punctures, interspaces substrigulate; remaining surface of prosternal process strigulate, impunctate; carinal prosternal striae convergent anteriorly, united in front of carinate lateral prosternal striae.

Anterior margin of mesoventrite (Fig. 220) deeply emarginate medially; discal marginal mesoventral stria complete; disc with scattered punctures, separated by 1–3 times their diameter; meso-metaventral sutural stria undulate, somewhat distanced from meso-metaventral suture.

Intercoxal disc of metaventrite (Fig. 220) with scattered punctures, separated by several times their own diameter; lateral metaventral stria well impressed, shortened; lateral disc of metaventrite (Fig. 222) with shallow setiferous punctures; metepisternum with denser punctures, separated by about their own diameter, punctures with microscopic setae, base of metepisternum + fused metepimeron (Fig. 222) almost smooth, with several scattered punctures.

Intercoxal disc of first abdominal sternite completely striate laterally, disc with regular round punctures separated by their own to twice their diameter.

Protibia (Fig. 217) dilated, outer margin with three large teeth, topped by round denticle, followed by two minute round denticles; protarsal groove deep; outer row of setae moderately dense and long; median row of setae sparser, setae shorter; anterior protibial stria shortened apically; protibial spur tiny, growing out from apical margin of protibia; outer part of posterior surface with shallow wrinkles intermingled with sparse umbilicate punctures; median part of posterior surface glabrous, separated from outer part by vaguely costiform stria; posterior protibial stria weakly impressed; inner margin of protibia with sparse short ramose setae; single inner posterior denticle present.

Mesotibia (Fig. 223) slightly dilated and thickened, outer margin with two rows of dense denticles growing in size apically; outer row of setae sparse, setae long and strongly sclerotized; setae of median row much shorter and weaker; posterior mesotibial stria almost complete; ventral surface almost smooth, with microscopic wrinkles; anterior mesotibial stria somewhat shortened apically; inner row of setae short; mesotibial spur long; apical margin of mesotibia anteriorly with three inner anterior denticles; claws of apical tarsomere bent, longer that half its length; metatibia (Fig. 224) somewhat thicker than mesotibia, otherwise in all aspects similar to it.

Male genitalia. Eighth sternite (Figs. 225–226) longitudinally separated medially, apically with large inflatable membrane (velum) with single row of short dense setae; apex laterally with few longer sparser setae; eighth tergite and eighth sternite fused laterally (Fig. 227). Morphology of 9 th tergite (Figs. 228–229) typical for the subfamily; spiculum gastrale (Fig. 228) expanded on both ends. Basal piece of aedeagus (Figs. 230–231) short, ratio of its length: length of parameres 1: 4; parameres fused along their basal two-thirds; aedeagus gently curved ventrad (Fig. 231).
