TYPE MATERIAL. — Holotype. China • ♂ (1459); Hainan Prov., Jianfengling National Forest Park; 18°49’N, 108°90’E; 9.VIII.2018; Zhu-Qing He leg.; ECNU; GenBank: OR033151.
Paratypes. China • 2 ♀ (1779, 1889); Hainan Prov., Changjiang, Baomeiling Provincial Nature Reserve; 19°17’N, 109°05’E; 18.III.2019; Zhu-Qing He leg.; ECNU; GenBank: OR033152; OR033153.
ETYMOLOGY. — The specific epithet tianya is for the Chinese phonetic alphabet 天涯. This means the end of sky, and it also refers to Hainan Island, where is the type locality of the new species. Chinese name: 天涯ũ须蟋.
DIAGNOSIS. — Almost uniform yellowish brown. Hind femur spotted (different from other species of this genus in China) (Fig. 2A, B; 6A). Hind wings slightly longer than forewings (Fig. 5A), comb of tegminal Sc with 6-7 branches. Pseudepiphallic lophi bearing two semicircular-like projections apically.
DISTRIBUTION. — China (Hainan).
DESCRIPTION
Male
Head. Vertex broad and flattened. Head wider than anterior margin of pronotum; frontal rostrum convex, densely pubescent (Fig. 2A, B). Median ocellus smallest of the three ocelli, ovoid (Fig. 6A); lateral ocelli larger and flatter than middle one, transversely ovoid. Eyes strongly prominent and large, about 1/2 the length of head.
Thorax. Pronotum broad, finely pubescent; posterior margin longer than anterior; anterior margin straight and posterior slightly convex; two eyelike spots of pronotum disc distinct and smooth (Fig. 5A). Longitudinal veins of forewings parallel, costal area of tegmina with only a few crossveins irregularly situated between branches of Sc.Forewings slightly shorter than hindwings, comb of tegminal Sc with 6-7 branches. Distal half of forewings usually with small darkish spots around crossveins.
Legs. Only inner side of fore tibia with elongate-ovoid tympanum, pitted (Fig. 3A, B). Hind tibiae serrulated, with short and thin spines among subapical spurs, sparser as closer to the apex (os5-os4:3, os4-os3:3, os3-os2:1, os2-os1:0; is6-is5:3, is5-is4:1, is4-is3:1, is3-is2:0, is2-is1:0); with six inner and five outer subapical spurs; three inner and three outer apical spurs, outer spurs short (middle one longer; other two equal in length) and the inner spurs long (superior one longest, inferior one shortest) (Fig. 4A).
Male genitalia. Pseudepiphallic sclerite broadly triangular, slightly concave, without arms; lophi big, separated by a roughly triangular indentation apically, apically bearing two semicircular-like projections and armed with setose. Pseudepiphallic plate inconspicuous between lophi; posterior margin convex. Pseudepiphallic parameres spindly, more or less concave on inner side. Rami connected to pseudepiphallic sclerite. Ectophallic fold unobtrusive, visible just below the lophi, regularly narrowed toward apex, reaching posterior margin of pseudepiphallic parameres; ectophallic apodemes thick.Ventral valves united as one membranous lobe. Endophallic sclerite evident, more or less V-shaped. No dorsal cavity (Fig. 5 B-D).
Female
Similar to male, but slightly larger than male, with distinct dark brown ornament on dorsum (Fig. 2B; 7A).
Ovipositor. Dorsal valvulae blunt at end, possessing three projections on apical margin and an irregularly elevated surface (Fig. 7B, C). Ventral valvulae blade-shaped, apically blunt. Protrusion of its lateral margin short and thick (Fig. 7B, C).
Female genitalia. Copulatory papilla longer than wide, funnel-shaped, with ventral aperture; posterior margin slightly invaginated like “w” form (Fig. 7 D-F).
Coloration. Body yellowish brown. Head brown; clypeus and labrum yellowish. Pronotum yellowish brown. Slight darkening around crossveins in distal half of forewings. Darkened bases of spines on hind tibiae. Small darkish spots near spines (Fig. 2A, B; 5A).
