Guangdong: Xinfeng, Yunji Mountain (
Dorsal side bicolored, with strong metallic luster, pronotum cupreous green, elytra dark purple; pronotum slightly narrowed to the base; posterior angles completely rounded; pronotal base including the basal fovea completely glabrous; basal fovea with inner and outer grooves well defined; metepisternum short and wide, length subequal to its basal width; median lobe of aedeagus strongly lobed and notched on the left margin.
The new species is different from all other known species of
Yunji Mountain, Xinfeng, Guangdong. Only known from the holotype.

Hunan: Guidong, Bamian Shan Mt. (
Dorsal side bicolored, pronotum metallic dark green, elytra dark purple; pronotum strongly narrowed to the base; posterior angles obtuse-rounded; pronotal base including the basal fovea completely glabrous; basal fovea with inner and outer grooves vaguely defined, anterior half separated from each one, posterior half fused together; metepisternum short and wide, length subequal to its basal width.
This new species can be readily distinguished from all other
