Measurements (mm).

Overall length: ♂ 25.0, ♀ 23.0; pronotum length × width: ♂ 5.4 × 6.2, ♀ 5.5 × 6.4; tegmina: ♂ 22.5, ♀ 18.7.

Description.

Male. Coloration: Large body, yellowish-brown to dark brown (Fig. 5A, B ), face brown, ocelli milky (Fig. 5C ). Maxillary palps brown (Fig. 5E ). The base of antenna yellowish brown, the rest dark brown. Pronotum yellowish-brown with posterior border black brown (Fig. 5D ). Head: Interocular distance obviously less than the distance between antennal sockets. Third segment of maxillary palps as long as the fifth segment, slightly longer than the fourth (Fig. 5E ). Posterior margin of pronotum obviously convex (Fig. 5D ). Tegmina and hindwings: Both fully developed, extending beyond the end of abdomen (Fig. 5H, I ). Hind wings with RP bifurcated near the midpoint; the apex of M branched; CuA curved with 5-6 complete branches and 3 incomplete branches (Fig. 5I ). Legs: Front femur Type A3 (Fig. 5F ), pretarsal claws with pulvillus symmetrical and unspecialized. Abdominal tergites: Center of T1 ridged with a cluster of setae, T7 with a pair of obvious depressions and a tubercular process, where some bristles are present in the middle (Fig. 5G ). T10 symmetrical, posterior margin slightly concave, and anterior margin with a cluster of setae. Paraprocts: Dissimilar, the right one with a curved and spine-like process at base, left one with 3 spine-like processes of variable size (Fig. 5J ). Subgenital plate: Hind margin asymmetrical, left stylus arising at posterior margin with some spinules; right stylus crooked and irregular (Fig. 5N ). Male genitalia: L3 on the left side, of which the apex has an incision (Fig. 5K ); L2vm rod-like and with branches at apex (Fig. 5L ); R2, R3 made up of several sclerites (Fig. 5M ).

Etymology.

The Latin word tubercularis indicates T7 with a tubercular process in the middle.

Remarks.

Symploce tubercularis Jin and Che sp. nov. is closely related to Symploce maxima ( Li et al. 2020) comb. nov., however, they can be distinguished by the following characteristics: 1) the former with a tubercular process in the middle of T7 that is absent in the latter; 2) the former with the right stylus crooked and irregular, while the latter has two small and simple styli; 3) the former with a setal tuft on supra-anal plate, but the latter without.

Distribution.

China (Guangxi).
