Length. 15.0-17.0 mm; width: 5.5-6.0 mm. Habitus as in Fig. 4. Figures 4-7. Habitus 4 Orthogonius jianfengling 5 Orthogonius himalayicus 6 Orthogonius limbourgi sp. n. 7 Orthogonius politior sp. n. Scale bar: 5.0 mm. Description. Body elongate, strongly shiny, smooth and glabrous; head dark brown, pronotum, elytra and legs red brown, impunctate, microsculptural engraved meshes isodiametric. Head slightly longer than wide, HL/HW = 1.11; clypeus bisetose, labrum sex-setose, shallowly emarginate at apical margin; mentum edentate; each of mentum and submentum bisetose. Pronotum strongly transverse, PW/PL = 1.55, disc moderately convex, apical and basal margins well beaded, sides evenly expanded, widest at middle; base slightly wider than apex, lateral expanded margin well-defined, evenly and distinctly reflexed. Elytra elongate, and rather flat, EL/EW = 1.84, widest at about middle, parallel-sided at middle, basal border complete, apex bisinuate, inner angle blunt, not denticulate at tip (Fig. 14), the 3rd interval with three setiferous pores. Legs slender, fore tibiae expanded at apex, with outer angle strongly protrude, outer margin smooth, sub-serrate; middle coxae setose medially, hind coxae smooth and glabrous, the 3rd and 4th hind tarsomeres subequal in length, the 4th bilobed at apex; all tarsal claws weakly pectinate. Prosternal process bordered at apex. Male: Unknown. Remarks. It is probably close to Orthogonius limbourgi sp. n., distinguished from the latter by its distinctly reflexed lateral expanded margins of pronotum (slightly reflexed in Orthogonius limbourgi ), and setose middle coxae (asetose in Orthogonius limbourgi ). Material examined. 1 female, the holotype, "Hainan: Ledong Xian: Jianfengling, 15. VI. 1983, Gu Maobin leg.", in SCAU; 1 female, a paratype, ibid. in MNHN. Distribution. China (Hainan Island) (Fig. 3a).
