Diagnosis.
Dorsal surface nearly black, with very weak bluish luster; femora dark brown to piceous; mouth parts, tibiae, and tarsi sometimes lighter. Mentum with anterior margin straight at middle. Elytra narrowed toward shoulders; elytral striae incised with large punctures (much smaller than interval width). Median lobe of aedeagus in lateral view equally broadened before apical third and then abruptly narrowed; ventral margin strongly curved before apex.
Supplementary description.
BL 13.9–16.1 mm (15.0 mm in the holotype); dorsal and ventral surface nearly black, with very weak bluish luster; mouth parts brown; femora dark brown to piceous; tibiae and tarsi sometimes lighter (Fig. 2 B). Head: labrum trilobate; medial lobe slightly extended anteriorly; anterolateral angles rounded-obtuse, sparsely pubescent near anterior margin; clypeus impunctate and pubescent; vertex densely and coarsely punctate; temporae slightly shorter than eyes, well tumid behind eyes, sparsely and finely pubescent and punctate. Pronotum: PL / PW 1.62–1.68; lateral margins gradually sinuate twice, behind anterior angles and before posterior angles; sides flattened from above and a little extended laterally near middle, median region elevated. Elytra: EL / EW 1.44–1.50; base with 7–8 parascutellar pores, strongly narrowed at shoulders; elytral striae incised with large punctures (much smaller than interval width). Male genitalia: median lobe of aedeagus relatively stout (Fig. 4), equally thickened before apical third and then abruptly narrowed in lateral view, with ventral margin strongly curved before apical lamella (Fig. 4 A, D); same in dorsal view, with apical lamella short (ALL / ALW 0.46–0.51), obtuse and rounded; endophallus with a central sclerite, hook-shaped in right lateral view (Fig. 4 A), with blurred border in ventral view (Fig. 4 B).
Distribution.
This species is widely distributed in the Nanling Area of southern China (Fig. 1), where it is currently recorded from four provinces: in southern Guizhou from Mount Leigongshan (new provincial record); in southern Hunan from Mount Mangshan (new provincial record); in north Guangxi from Mounts Maoershan, Dayaoshan, and Cenwanglaoshan; and in northern Guangdong from the Nanling Natural Reserve.
