Diagnosis. This is a distinctive species with dual vestiture of longer and shorter bristles, confused elytral punctation, broad lateral pronotal margins and distinctly produced anterior pronotal angles. Males have paired triangular frontoclypeal and pronotal plates.
Description. With characters of the genus. Body moderately elongate and convex, with sides of pronotum slightly rounded but elytra more or less parallel-sided. Length = 1.25–1.50 (1.38 ± 0.08, n = 11) mm. BL/EW 2.03– 2.24 (2.13); GD/EW = 0.72–0.81 (0.75). Colour of head and pronotum reddish-brown, elytra yellowish-brown to reddish-brown, undersides usually reddish-brown, legs yellowish-brown, antennae yellow; surfaces moderately shiny. Dorsal vestiture dual, consisting of longer and shorter yellow bristles. Frons and vertex flat in female, anteriorly concave in male, without vertexal sex patch. Longest eye diameter 0.24 times as great as head width. Frontoclypeal ridge in both sexes complete at middle, evenly produced and elevated in female, and forming a pair of triangular plates in male, separated by about one basal width. Antennomere length ratio: 3.67: 2.50: 3.00: 1.83: 1.25: 1.17: 1.00: 2.50: 2.33: 4.17; length/width ratios: 1.29, 1.25, 3.00, 1.57, 1.07, 1.00, 0.71. 1.07, 0.87, 1.67. Apical maxillary palpomere 2.40 times as long as wide, widest at about middle, apex truncate. Labial palps separated by 0.20 times basal width of one; ratio of palpomere lengths 1.00: 2.00: 1.50, apical palpomere distinctly narrower than preapical one, which is inflated. Male gula 0.44 times as wide as head, densely filled with micropores, the pores not or barely extending anteriorly onto submentum; female gula 0.34 times as wide as head. Pronotum 0.80–0.85 (0.83) times as long as wide, barely wider at about middle in both sexes; anterior edge strongly rounded in female, produced to form a pair of short, narrowly separated triangular plates in male; lateral margins broad, easily visible for their entire lengths from above with finely crenulate edges; anterior angles distinctly produced forward and rounded; posterior angles rounded; posterior edge with very narrow but complete marginal bead; disc evenly convex; punctation coarse and dense, punctures usually separated by less than a half a diameter; interspaces distinctly sculptured and somewhat shiny. Prosternum in front of coxae 1.2 times as long as mid length of procoxal cavity, slightly tumid without median longitudinal carina, prosternal process 0.50 times as wide as mid length of coxal cavity, truncate at apex; procoxal cavities very narrowly open; postcoxal process narrowly acute. Elytra 1.28–1.42 (1.35) times as long as wide and 1.63–1.86 (1.74) times as long as pronotum; punctation dual and confused, with megapunctures about as large as pronotal punctures, the interspaces very finely sculptured and shiny. Mesocoxal cavities separated by about 0.17 times shortest diameter of a cavity. Metaventrite slightly convex; discrimen about 0.5 times length of ventrite; shortest distance between meso- and metacoxal cavities about 1.40 times length of abdominal ventrite 1. Outer apical angle of protibia with distinct tooth in male, angulate in female. First abdominal ventrite 1.67 times as long as 2nd; sex patch in male about 0.27 times as long as ventrite 1, located at middle, longitudinally oval, with partial rim. Sides of sternite VIII straight and strongly and converging, its apex abruptly and moderately deeply emarginate, with acute, sclerotised angles. Pregenital ring broad with subacute apex. Tegmen (Fig. 65) 2.62 times as long as wide, sides more or less straight and parallel to apical tenth, then evenly converging to subacute apex at one level but distinctly curved at another level, producing a pair of anterolateral pockets, base broadly subangulate (but possibly damaged). Penis equal in length to tegmen and 3.32 times as long as wide, sides subparallel to about middle, slightly diverging and curved to apical fourth, then converging to acute apex; base rounded. Ovipositor (Fig. 82) 3.27 times as long as wide, widest near base of gonocoxites, with sides subparallel basally, slightly diverging near base of gonocoxites, then gradually converging to apex; paraprocts 1.19 times as long as gonocoxites, longitudinally oriented; gonocoxites 1.40 times as long as their combined widths; proximal lobe about 1.30 times as long as wide, not subdivided; distal lobe about 1.22 times as long as proximal lobe, gradually narrowed to narrowly rounded apex; gonostylus about 0.36 times as long as distal lobe and 4 times as long as wide.
