(Figs. 2, 3, Map 1)
Male. Size normal for the genus. Fastigium verticis broad, about 2 times as broad as scape, lateral margins not raised. Scape elongate, shorter than the length of eye; pedicel about three-quarters length of scape; first segment of flagellum as long as pedicel. Eyes elongate and faintly oval; median ocellus subcircular; lateral ocelli very prominent, ovoid (Fig. 2 A). Anterior margin of pronotum slightly projected in the middle, posterior margin nearly truncate; lateral lobes longer than high, ventral margin nearly straight (Fig. 2 B–C). Hind femora with 2–5 inner and 7–9 outer ventral spines; tibiae with 6–7 pairs of short, robust spines on dorsal surface, these becoming larger apically. Tegmina considerably surpassing apices of hind femora, reaching the middle area of hind tibiae; hind wings slightly longer than tegmina. Ninth abdominal tergite divided in the middle, forming two lobes, the apices with 1 small hook, which invisible in dorsal view (Fig. 2 D, F, G), its apex acute. Cerci longer, cylindrical, the basal four-fifths nearly straight, the apical curved outwards. Subgenital plate wider than long, anterior margin arched concave, posterior margin with 1 shallow obtuse-triangular concavity (Figs. 2 E–F, 3D). Styli conical, faintly incurved, apices obtuse, located on the lateral margins of subgenital plate near apex (Fig. 2 F).
Female. Differs from the male in the following: median and lateral ocelli more conspicuous than male. Posterior margin of seventh abdominal sternite with 1 long process, directing backwards, the apex with 1 small median concavity. Cerci slender, conical. Subgential plate longer than broad, narrowing, posterior margin with 1 triangular concavity in the middle, the lateral lobes triangular (Figs. 2 L, 3B). Ovipositor as long as hind femora, strongly upcurved, dorsal valvulae with apices obliquely truncate (Figs. 2 K, 3C).
Coloration. Yellowish green. Male ocelli pale yellow, female ones yellow. Dorsal surface of tegmina reddish brown. Spines of hind legs with apices black. Ovipositor brown.

Distribution. China (Zhejiang).
Remarks. The new species differs from the Eugryllacris cylindrigera (Karny, 1926) in: posterior margin of female seventh abdominal sternite with a longer median process, its apex with 1 small median concavity, subgenital plate as long as broad. In Eugryllacris cylindrigera (Karny, 1926) the female seventh abdominal sternite with a shorter median process, its apex nearly truncate, subgenital plate broader than long.
Etymology. Named with reference to the longer posterior process of female seventh abdominal sternite.
