Overall length: ♂ 20.6, ♀ 19.6; pronotum length × width: ♂ 4.3 × 4.9, ♀ 4.2 × 5.1; tegmina: ♂ 17.5, ♀ 16.4.

Description.

Male. Coloration: Body yellowish brown or brown (Fig. 2A, B ). Ocelli pale yellow. Antennae yellowish brown with base pale yellow. Maxillary palps with fourth and fifth palpomeres yellow brown, others pale yellow (Fig. 2E ). Pronotum yellowish brown, with a light-colored vertical stripe at disk (Fig. 2C, D ). Head: Interocular space slightly less than ocelli width and distinctly narrower than width of antennal sockets. Third and fifth maxillary palpomeres about same length, and slightly longer than the fourth (Fig. 2E ). Posterior margin of pronotum slightly convex in the middle (Fig. 2D ). Tegmina and hindwings: Both fully developed, extending beyond end of abdomen (Fig. 2H, I ). RP of hindwings with branches near the middle, CuA curved as “S” with 4 complete and 3 incomplete branches (Fig. 2I ); apical triangle small. Legs: Anteroventral margin of front femur Type A3 (Fig. 2F ), pretarsal claws symmetrical and unspecialized. Abdominal tergites: T1 specialized with a setal tuft in the middle; T7 specialized with a pair of shallow fossae and a setal tuft in the middle, two dark brown spots on each side of the tuft (Fig. 2G ). T10 with a median ridge, where a bunch of bristles is born, hind margin broadly and weakly concave. Paraprocts: Dissimilar, right one with a long spine and a cockscomb-like process, and left one with a shorter spine-like process distad (Fig. 2J ). Subgenital plate: Asymmetrical, styli cone-shaped, the right one located on the apex of a protrusion arising from middle of hind margin, and left one slightly larger and near base of right one (Fig. 2N ). Male genitalia: L3 on the left side with a subapical incision (Fig. 2K ); proximal end of L2vm with an inconspicuous bifurcation, and the apex sharp (Fig. 2L ); R2, R3 complex with a Y-shaped sclerite (Fig. 2M ). - Female. Like male (except for postabdomen).

Etymology.

The specific epithet is derived from the Latin word ericeus, referring to the right paraproct scattered with spines.

Remarks.

Centrocolumna ericea Jin and Che sp. nov. resembles Centrocolumna striata striata comb. nov., but differs from it as follows: 1) the former with a setal tuft on T1, but the latter without; 2) the former with the left stylus larger than right one, but the latter with the right stylus larger than left one. Furthermore, the general color differs greatly among specimens of the new species collected in different provinces: specimens from Chongqing and Fujian are generally yellowish brown, specimens from Hunan are brown, and specimens from Guangxi are dark brown. In terms of paraprocts, there are some minor differences exhibited in the cockscomb-like process of right paraproct, the teeth usually ranging from 2 to 8.

Distribution.

China (Chongqing, Fujian, Guizhou, Jiangxi, Guangxi, Guangdong, Yunnan, Hunan).
