Figure 2, Map 1
Description. Male. Body small, medium for the genus. Fastigium verticis conical, protruding forwards, apex obtusely rounded, with a shallow longitudinal sulcus. Eyes oval. Maxillary palpi long, apical segment almost equal to subapical one, apex slightly widened.
Pronotum short, anterior margin comparatively straight, posterior margin obtusely rounded, lateral lobes longer than deep, humeral sinus indistinct. Thoracic auditory spiracles ear-shaped, exposed. Procoxa with 1 spine; protibia with 5 spines on inner margin and 4 spines on outer margin of ventral surface, spines long near the base, slightly short near the apex; tibial tympana open on internal and external sides, oval. Mesotibia with 5 spines on inner margin and 4 spines on outer margin of ventral surface, spines comparatively shorter. Posttibia with 28–30 spines on inner margin and 26–29 spines on outer margin of ventral surface, with two pairs of ventral apical spurs and one pair of dorsal apical spurs. Tegmina narrowly long, surpassing apices of postfemora, apices rounded; hind wings longer than tegmina.
Tenth abdominal tergite long, the centre of posterior margin with a long posterior process (Fig. 2 C), which curved downwards, base thick, slightly narrow, apical half depressed, slightly narrowing, apex obtusely rounded. Cerci stout, base with a short conical process on the outer margin of ventral surface, apical half compressed, curved inwards, apex obtusely rounded, middle area with a nearly triangular process dorsally (Fig. 2 D – E). Subgenital plate complicated (Fig. 2 F – H), basal half wide; base with a triangular concavity, the middle of lateral margin folded dorsally, the apical area extending backwards, forming a triangular process, apex obtusely rounded; apical half of subgenital plate narrow, lateral margins near middle area with a slender spinous process separately directing backwards, apices obtusely rounded; apical area of subgenital plate curved ventrally, oval in ventral view, edge folded ventrally, near lateral margin of dorsal surface with carinae, apex with a small triangular notch; without styli.
Coloration. Body light green. Eyes dark brown. Dorsum of head with one pair of dark brown stripes, extending to posterior margin of pronotum; the area between the brown stripes on disc of pronotum light brown. Spines on ventral surface of tibiae dark brown, spurs of posttibiae dark brown. Postfemoral genicular lobe with a black spot. Stridulatory area brown.
Female. The appearance and coloration are similar to male. Cerci conical, with base stout, apex acute. Ovipositor long and narrow, moderately curved upwards, apices of ventral valvulae with small hooks. Subgenital plate broad in middle area, apical part with middle lobe (Fig. 2 I).
Type material. Holotype: male, Hupingshan, Shimen, Hunan, 18 August 2004, collected by Jian-Feng Wang & Ji-Liang Wang; paratypes: 1♂ 8♀, other data as holotype; 1♀, Hupingshan, Shimen, Hunan, 19 August 2004, collected by Jian-Feng Wang & Ji-Liang Wang; 2♂ 3♀, Jiemuxi, Yuanling, Hunan, 2 August 2004, collected by Jian-Feng Wang & Ji-Liang Wang; 2♂, Zhangjiajie, Hunan, 7 August 2001, collected by Fu-Ming Shi; 5♂ 7♀, Zhangjiajie, Hunan, 14 August 2004, collected by Jian-Feng Wang & Ji-Liang Wang.
Measurements (mm). Body: ♂9.2–11.5; ♀9.1–11.0; pronotum: ♂4.4–4.6, ♀4.5–4.6; tegmina: ♂13.5–14.6, ♀16.5–17.8; postfemora: ♂9.2–10.5, ♀11.2–11.5; ovipositor: 8.8–9.2.
Discussion. The new species is allied to Xiphidiopsis (Xiphidiopsis) tonicosa Shi & Chen, 2002, but it differs from the latter in: apical half of male cercus compressed, curved inwards, apex obtusely rounded; subgenital plate rather complicated (as figure 2F–H shown).
Although Wang et al. (2014) thought that Xiphidiopsis (Xiphidiopsis) tonicosa Shi & Chen, 2002 should belong to the genus Xizicus, but we checked the type specimens, which bear a long unpaired posterior process of male tenth abdominal tergite and complicated cercus, without membranous area. Thus, we insisted the original classification status of this species.
Etymology. The name of the new species is derived from the character of male subgenital plate, showing lateral margin near middle area with a slender spinous process separately directing backwards.
Distribution. China (Hunan).
