Fig. 1 View Figure 1

Description.

Body subelliptical-elongate in dorsal view, with subparallel sides (Fig. 1 A, B View Figure 1 ), distinctly convex in lateral view. Dorsal surface glabrous, bicoloured in the only known species, with yellowish head and pronotum, and reddish brown elytra. Head (Fig. 1 E View Figure 1 ) with frontal grooves, frontal carina, and frontal calli barely distinguishable; surface smooth or micropunctate, with rounded punctures approx. as large as the supraorbital setiferous pore; puncture absent on the middle of front and vertex; eyes large, ovoidal; minimum distance between eyes on vertex, as wide as 2 × the interantennal space; interantennal space prominent compared to the clypeus, as wide as ~ 2 / 3 the length of the first antennomere; maxillary palpi three-articulated, and labial palpi bi-articulated, both with slender, subcylindrical segments. Antennae (Fig. 1 A, B View Figure 1 ) with 11 antennomeres, filiform, longer than 1 / 2 the body length in both sexes, but slightly shorter in female; antennomere II slightly shorter than 1 / 2 of antennomere I and as long as 1 / 2 of antennomere III; antennomere IV as long as (female) or slightly longer (male) than antennomere III; antennomeres V – IX generally slightly longer than antennomere I (male) or approximately as long as antennomere I (female); antennomere X slightly shorter than antennomere I, especially in female; antennomere XI distinctly longer than antennomere I. Prothorax distinctly depressed dorsally (not subcylindrical). Pronotum (Fig. 1 D View Figure 1 ) subrectangular, slightly convergent anteriorly, with curved, moderately expanded lateral margins, clearly visible in dorsal view; basal margin moderately arched; surface smooth to micropunctate without any groove or depression; anterior angles barely prominent; posterior angles widely obtuse; punctation rounded, quite sparse and irregularly distributed. Scutellum subtriangular. Elytra (Fig. 1 A, B, D View Figure 1 ) subparallel, with base as wide as pronotal base; lateral margins finely bordered, barely visible in dorsal view; punctation rounded, variably arranged in numerous rows or bands, or almost confused. Epipleurae oblique, clearly visible in lateral view. Procoxal cavities open posteriorly; prosternum approx. as wide as the procoxal cavities; intercoxal prosternal process quite narrow; mesosternum slightly wider than prosternum, and distinctly wider than mesocoxal cavities; metasternum wider than mesosternum, twice the width of the metacoxal cavities; first abdominal ventrite as wide as metacoxal cavities. Posterior femora elliptical-elongate, moderately swollen; dorsal margin of middle and hind tibiae with distinct ciliate emargination, acute apically; hind tibiae straight in dorsal view; apical spur of hind tibiae simple; third visible metatarsomere deeply incised; fourth visible tarsomere of metatarsus simple, not swollen in both male and female; claws appendiculate. Metafemoral extensor tendon (Fig. 1 H View Figure 1 ) with extended arm (ea: Fig. 1 H View Figure 1 ) as long as ~ 1 / 2 the dorsal lobe (dl: Fig. 1 H View Figure 1 ); dorsal-basal angle (dba: Fig. 1 H View Figure 1 ) approx. right angled, moderately prominent apically; ventral-basal angle (vba: Fig. 1 H View Figure 1 ) distinctly obtuse and moderately rounded; apical margin of the tendon (am: Fig. 1 H View Figure 1 ) slightly C-shaped; dorsal margin of ventral lobe (dmv: Fig. 1 H View Figure 1 ) oblique; basal angle of ventral lobe (bav: Fig. 1 H View Figure 1 ) quite close to the dorsal-basal angle of the tendon. Median lobe of the aedeagus (Fig. 1 F View Figure 1 ) mostly subparallel in ventral view, with truncated apex, and curved in lateral view; dorsal ligula formed by a wider central lobe, and two lateral lobes. Spermatheca (Fig. 1 G View Figure 1 ) with subovate basal part, narrowing towards ductus attach; distal part thin, without a distinct collum.
