Figs. 12A–H

Material examined: Holotype ♂, CHINA, Guangxi Prov., Jinxiu (110.10°E, 24.15°N), 19-vii-2015, coll. He Zhu- Qing & Lu Hui.

Paratypes: 1♂, CHINA, Guangxi Prov., Jinxiu (110.10°E, 24.15°N), 21-vii-2015, coll. He Zhu-Qing & Lu Hui ; 1♀, CHINA, Guangxi Prov., Jinxiu (110.10°E, 24.15°N), 20-vii-2015, coll. He Zhu-Qing & Lu Hui.

Description: Male: Size medium. Pronotum with sparse tubercles. Side lobes abdominal edge with tumors ( Figs.12B, C ). Front corners of mesosternum protruding tooth-shaped ( Fig. 12D ). Fore femora on the ventral inside edge with 5–9 spines, 3–9 spines on the outside edge. Hind femora with 12 lower outer, 8–13 lower inner and 11 upper median spines. Fore femora and median femora dark ventrally. Tegmina with almost truncated apical part ( Figs. 5I, J ). Epiproct nearly oval, with intermediate longitudinal ridge ( Fig. 12E ). Cerci robust, almost conical ( Figs. 12E, F ).

Female: Similar to male in general appearance, but larger than male. Subgenital plate subtriangular, notched in terminal ( Fig. 12G ). Ovipositor wide relatively, distal half of dorsal margin armed with fine teeth ( Fig. 12H ).

Comparison. H. (T.) spinosus robustus subsp. nov. is very similar to H. (T.) spinosus spinosus ( Figs. 11A–H ; 12A–H ), but differs in the size (length of pronotum, tegmina, and hind femora of male in H. (T.) spinosus robustus subsp. nov. are 7.7–7.9, 35.8–36.2 and 18.9–20.6mm respectively, but these are 7.3–8.3, 30.3–34.2 and 17.6–19.6 mm in H. (T.) spinosus spinosus , respectively). H. (T.) spinosus robustus subsp. nov. have more spines on hind femora dorsally than H. (T.) spinosus spinosus (11 vs. 7–9).

Measurements (in mm): Male: SZ 45.0–47.9, PR 7.7–7.9, FW 35.8–36.2, HF 18.9–20.6; Female: SZ 59.2, PR 10.5, FW 47.9, HF 22.3, OV 19.4.

Etymology: Subspecies name robustus means it’s stronger than H. (T.) spinosus spinosus .

Distribution: China (Guangxi).
