Description

Dark brown to black, lateral expanded margin of pronotum, antennae, mouthparts palpi, legs and underside surface reddish brown. Wrinkles and punctures: surface smooth and impunctate; head and pronotum faintly striate, odd elytral intervals (3, 5, 7) with distinct fine punctures which are irregularly rowed; surface strongly shiny. Microsculptural meshes densely isodiametric, clear on elytra, but faint on pronotum and head. Head stout, as long as wide; eyes very large, strongly prominent, frons and vertex moderately convex, frontal impressions small, short, fovea-like, clypeus bisetose, rather even, labrum sexsetose, nearly straight at apical margin; ligula very small and narrow, bisetose at apex; palpi slender, subcylindrical, normal; palpiger asetose, mentum without median tooth, asetose, mentum and submentum each with one pair of setae. Antennae slender, extended beyond basal 1/3 of elytra, pubescent from apical 2/3 of antennomere 4; antennomeres 3, 4 and 5 subequal in length; antennomeres 1–3 glabrous; antennomeres 4–6 distinctly expanded laterally. Pronotum strongly transverse, PW/PL=1.88–1.90, sides evenly rounded, widest at about middle, both basal and fore margins beaded, lateral expanded margins well defined, wide and even, flat and smooth; both fore and hind angles rounded; disc strongly convex, fore transverse impression faint, basal one moderate, basal foveae small. Elytra broadly ovate (EL/WL=1.55–1.57), strongly convex, basal border well complete; sides slightly expanded in middle portion, hardly parallel-sided, widest at middle; striae deep, punctate-striate, intervals distinctly convex; intervals 2–5 subequal in width, interval 6 much wider than 5; odd intervals with more distinct fine punctures, irregular in row; apex roundly truncate, inner angle finely toothed, and with a wider sutural angle; interval 3 with three well marked setiferous pores, near striae 3, 2 and 2, respectively; interval 7 simple, wide and not carinate, without seta throughout. Legs moderate, fore tibia with outer angle nearly rectangular, blunt, outer margin not serrate; middle and hind coxae smooth and glabrous; middle and hind tibia slender, apex slightly dilated, hind apical tibial spurs very long and sharp; tarsomere 3 much longer than 4, tarsomere 4 deeply emarginate at apex (about 1/3 deep as the joint); all tarsal claws strongly pectinate; hind femur with 2 posterior setae on ventral. Prosternal process well bordered at apex; apical margin of abdominal ventrite VII narrowly and shallowly emarginate in male. Male genitalia (Figure 21): Very similar to that of Orthogonius chaudoiri, straight, and arrowhead-shaped at apex in dorsal view, but more distinctly so than in Orthogonius chaudoiri, upper margin less sinuate, and apical lamella in dorsal view much longer and more elongate. Female. Unknown.
