description: Eugryllacris xiei Bian & Shi sp. nov.
(Fig. 6, Map 1)
Male. Size medium, form not especially robust. Fastigium verticis about 1.5 times wider than scape, lateral margins not raised. Scape elongate, about two-thirds length of eye, internal margin slightly swelling; pedicel and first segment of flagellum combined about as long as length of eye. Eyes elongate and oval, protruding outwards; median ocellus nearly circular, poorly defined; lateral ocelli small, ovoid, better defined than median ocellus (Fig. 6 A). Anterior margin of pronotum slightly projected in the middle, posterior margin almost straight; lateral lobes longer than high, ventral margin truncate (Fig. 6 B–C). Hind femora with 3 inner and 6 outer ventral spines, the outer ones faintly longer than inner ones; hind tibiae with 6 pairs of short, robust spines on dorsal surface, these becoming larger apically. Tegmina considerably surpassing apices of hind femora, reaching the three-fourths 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, completely concealed the abdominal tergite (Fig. 6 D–E), invisible in lateral view, its apex acute, directing forwards (Fig. 6 F). Cerci longer, cylindrical, the apical half slightly curved outwards (Fig. 6 E). Anterior margin of subgenital plate almost straight, posterior margin with 1 obtuse-triangular concavity, the lateral lobes obtusely rounded (Fig. 6 E). Styli conical, slightly curved inwards, which longer than the lateral lobes of subgenital plate, its apices obtuse, located on the lateral margins of subgenital plate near apex (Fig. 6 E).
Female. Differs from male in following characters: ocelli well defined. Hind femora with 3–4 internal and 5–6 external spines on ventral surface. Tegmina only reaching the basal third area of hind tibiae. Cerci longer, conical, its apices acute. Seventh abdominal sternite with 1 moderate length process, apical area slightly curved dorsad, its apex faintly concave in the middle (Fig. 6 J). Subgenital plate wider than long, strongly narrowing, centre of posterior margin with shallow triangular concavity, the lateral lobes obtusely rounded (Fig. 6 J). Ovipositor about as long as hind femur, strongly curved upwards (Fig. 6 K).
Coloration. Yellowish green. Eyes brown. Ocelli yellow. Spines of hind legs with apices black.
Measurements (mm). BWL: ♂ 31.5–34.7, ♀ 27.9–29.5; BL: ♂ 24.4–30.0, ♀ 23.5–24.5; PL: ♂ 7.2–7.5, ♀ 7.0–7.3; TL: ♂ 23.8–25.3, ♀ 19.4–22.7; HF: ♂ 16.8–17.4, ♀ 15.5–16.3; Ov: 16.5–16.9.
Material examined. Holotype: male, Guanhan, Wufeng, Hubei, 7 July, 2011, coll. by Zhou Gan. Paratypes: 1 male, Shengziping, Wufeng, Hubei, 11 July, 2011, coll. by Liao Pinglu; 1 female, Shengziping, Wufeng, Hubei, 10 July, 2011, coll. by Zhen Wanwen; 1 female, Maoping, Wufeng, Hubei, 16 August, 2002, coll. by Chang Yanlin.
Distribution. China (Hubei).
Remarks. The new species is similar to Eugryllacris elongata Bian & Shi sp. nov., but differs from the latter in: the concavity of male subgenital plated deeper; the process of female seventh abdominal sternite shorter, apical area slightly curved dorsad, the posterior margin of subgenital plate with 1 shallower concavity, the lateral lobes nearly obtusely rounded.
Etymology. Named in honour of Dr. Guang-Lin Xie who has provided us with many bush crickets and raspy crickets over the years.
