Material examined. 1♂ 4♀. China: Hainan Province, Ledong County, Mt. Jianfengling, Mingfeng Valley , 969 m, 18°44.627′N, 108°50.602′E. Collected by Shao-Li Mao on 15 June 2017 .

Description. Female. Appearance is similar to male. Fastigium verticis subtriangular; dorsum flat, protruding over frons vertex; basal area slightly broad, tapering forward; apex slightly truncate ( Fig. 5A ). Apical segment of maxillary palpi slightly shorter than subapical palpi, apex enlarged. Pronotum broad, anterior margin straight, posterior margin obtusely rounded, disc comparatively flat, lateral margins parallel, lateral lobe longer than high, ventral margin rounded, humeral sinus distinct. Tegmina developed, more exceeding apices of postfemora; basal area slightly broad, tapering; apices obtusely rounded; hind wings longer than tegmina. Procoxa with a spine, ventral surface of all femora without spines, internal and external sides of ventral margin of protibia with 5 spines separately, spines of internal side longer than external side, tibial tympana open on both sides, oval. Mesotibia with 4 spines and 5 spines on internal and external sides of ventral surface, respectively. Posttibia with 23–26 spines on internal and external sides of dorsal surface separately, one pair of dorsal apical spurs and two pairs of ventral apical spurs. Cerci slightly long, basal area slightly thinner, middle area stout, apices thin and subacute. Ovipositor long, apical half moderately upcurved, ventral valve with an apical hook ( Fig. 5C .). Subgenital plate nearly triangular in outline with ϒ-shaped keel; basal half area with a swollen bulge on both lateral sides, apical half area narrow, tongue shaped ( Fig. 5B ).

Colouration. Body light green when alive (yellowish in 100% ethanol). Disc of pronotum with a pair of longitudinal yellowish white stripes. Eyes yellowish brown. Apices of spines of posttibia yellowish brown. Posterior margin of tegmina light brown.

Measurements (mm). BL: ♀ 11.0–12.5; PL: ♀ 4.0–4.1; TL: ♀ 18.0–18.3; PFL: 8.5–9.0; OL: 8.0–8.5.

Conclusions

The complete mitochondrial genome of S. triangula (16,152 bp) displays a highly conserved composition, arrangement and structure compared with the mitochondrial genomes of other Tettigoniids. A T-stretch as a recognition sequence of the mitogenome replication origin and more than one distinct tandem repeat in the CR are common in Tettigoniidae mitogenomes. Both the ML and BI phylogenetic analyses supported the relationships of ( Lipotactinae ( Hexacentrinae ( Conocephalinae ( Meconematinae ( Bradyporinae , Tettigoniinae ))))) in the Tettigoniidae . The female of S. triangula is similar to the male in appearance. The ovipositor is long and moderately upcurved with a ventral valve that has an apical hook. The subgenital plate is nearly triangular in outline with a ϒ-shaped keel; the basal half of the area has a swollen bulge on both lateral sides and the apical half is tongue-shaped.
