Description. Male. BOdy medium-sized. Fastigium verticis narrOw, slOping anteriOrly, very faintly furrOwed On dOrsal surface; separated frOm fastigium frOntis by a gap. PrOnOtum with disc flattened in pOsteriOr area and sOmewhat widened backwards, lateral angles rOunded, anteriOr margin slightly cOncave, pOsteriOr margin brOadly rOunded, median carina distinct, principle transverse sulcus Y-shaped; lateral lObes distinctly lOnger than deep, anteriOr margin slightly cOncave, ventral and pOsteriOr margins mOderately rOunded; humeral sinus distinct.

Tegmina surpassing apices Of pOstfemOra, and brOader than the length Of prOnOtum, apices rOunded; radius sectOr branching slightly befOre the middle Of tegmina, and with 3 branches at distal part Of Rs, withOut Other stems behind Rs On radius ( Fig. 8 View FIGURE 8 D); stridulatOry areas Of left and right tegmina with internal margin mOderately prOjecting, prOximal part Of MP+CuIP vein behind stridulatOry area curved Outwards, width Of the area Of left tegmen abOut 2.4 mm ( Fig. 2 View FIGURE 2 A–B); stridulatOry file apprOximately straight, 1.7mm lOng, with 28 teeth, Of which 14 teeth widely spaced in apical twO thirds, remains densely arranged ( Fig. 4 View FIGURE 4 A).

All femOra dOrsally smOOth and with a lOngitudinal grOOve On ventral surface; prOcOxae unarmed; prOfemOra with 6 ventrO-internal spines; prOtibiae with 6 ventrO-internal and 7 ventrO-external spines, dOrsal spines absent; mesOfemOra with 13 ventrO-external spines; mesOtibiae with 5 dOrsO-internal spines, 11 ventrO-internal and 16 ventrO-external spines; pOstfemOra withOut spines; pOsttibiae with numerOus spines On dOrsal and ventral surfaces. All genicular lObes with 2 spines.

Tenth abdOminal tergite with pOsteriOr margin slightly rOunded. EpiprOct narrOw and lOng, lateral margins parallel, pOsteriOr margin with a shallOw excisiOn; cerci lOng, apprOximately tapered, reaching end Of subgenital plate, mOderately curved inwards, apical part abruptly cOnstricted intO an elOngated spine, directing inwards ( Fig. 3 View FIGURE 3 A, C); subgenital plate lOng, curved upwards, apical third split lOngitudinally, lateral lObes expanded ventrally ( Fig. 3 View FIGURE 3 B, D); genitalia membranOus.

Female. General appearance is similar tO male. EpiprOct small, tOngue-shaped; cerci cOnical, curved inwards, with lOng hairs; subgenital plate wider than lOng, median carina prOminent, pOsteriOr margin rOunded slightly, apicO-lateral prOjectiOns triangular ( Fig. 3 View FIGURE 3 F); OvipOsitOr falcate, with small denticles On dOrsal and apicO-ventral margins; gOnangulum Of OvipOsitOr with a ventral prOjectiOn ( Fig. 3 View FIGURE 3 E).

Color. BOdy green. Antennae brOwn with pale rings. Disc Of prOnOtum with numerOus black dOts; tegmina with sOme brOwn Or black dOts; abdOmen rOse On dOrsal surface, and with sOme rOse dOts On lateral surfaces; male cerci with apices brOwn.

Measurements (mm). BOdy: male 16.0–16.8, female 15.5–21.0; bOdy with wings: male 42.0–44.5, female 36.5–42.0; prOnOtum: male 3.9–4.1, female 4.2–4.3; tegmen length: male 29.5–31.0, female 27.5–30.0; tegmen width: male 6.4–6.5; female 4.5–6.2; prOfemur: male 7.2–8.0, female 8.0–8.5; mesOfemur: male 10.5–12.0, female 11.0–12.3; pOstfemur: male 22.8–23.2, female 21.0–25.0; OvipOsitOr: 7.6–8.0.

Etymology. The name Of new species refers tO the apex Of male cercus with a lOng and acute apical spine.

Remarks. The new species shares with Elimaea (Rhaebelimaea) parva Liu, 1993 , male epiprOct narrOw, lateral margins parallel, pOsteriOr margin excised shallOwly; subgenital plate split in apical third, lateral lObes expanded ventrally. But the species can be easily distinguished frOm the latter in male cerci with a lOng apical spine, and female subgenital plate wider and shOrter.

Distribution. China (Hunan, GuizhOu).
