Figure 2
Description. Male. Fastigium verticis about 1.7 times as broad as scape, apex obtusely rounded (Fig. 2 A). Pronotum subsellate, anterior margin projecting, posterior margin truncate; lateral lobes longer than high, rectangular (Fig. 2 C, E). External margin of fore coxae with 1 small spine; fore femora unarmed on ventral surface; fore tibiae with 5 pairs of spines on ventral surface. Middle femora unarmed on ventral surface; middle tibiae with 5 pairs of spines on ventral surface; dorsal surface of middle tibiae with 1 internal apical spine. Hind femora with 7 pairs of ventral spines; external and internal margins of dorsal surface of hind tibiae with 6 spines respectively, 1 pair of dorsal apical spines, 2 pairs of ventral apical spines, and 1 pair of ventral subapical spines.
Ninth abdominal tergite constricted in the middle, forming 1 transversal fold and 1 foveola; lateral margins with 1 pair of processes, their length slightly shorter than cerci, curved ventrad, conical (Fig. 2 G). Tenth abdominal tergite narrow, centre of posterior margin with 1 pair of robust processes, basal area arch shaped in apical view, centra slightly inflated outward, narrowing, curved forward; apical spines of processes compact, inserted the foveola of ninth abdominal tergite (Fig. 2 G–H). Subgenital plate rectangular, centre of basal area concave; posterior area wider than other species of the genus, posterior margin obtuse-triangular concave in the middle, the lateral lobes triangular with apices obtusely rounded. Styli robust located on both sides of posterior margin of subgenital plate (Fig. 2 I).
Female. Appearance of female is similar to male. Seventh abdominal sternite not membranous. Between seventh abdominal sternite and subgenital plate with some transversal folds, which have a concavity in the middle. Subgenital plate broad basally, narrowing, apex obtusely rounded (Fig. 2 L). Ovipositor long and straight (Fig. 2 K).
Coloration. Body flavotestaceous. Eyes blackish brown, with a black vertical stripe below eyes. Fastigium verticis with black spots; occiput yellowish brown, with 1 semicircular conspicuous black stripe (Fig. 2 A–B). Disc of pronotum black, with a yellowish brown spot on both sides (Fig. 2 C–F). Fore and middle tibiae with blackish brown spines, apices yellowish, apical spines of middle tibiae yellowish brown. Hind femora and tibiae with black spines, and apical spines yellowish brown, their apices blackish brown. Apical spines of processes on tenth abdominal tergite blackish brown (Fig. 2 G).
Material examined. Holotype: male, Jianfengling, Ledong, Hainan, 25 May, 2011, collected by Lehong Zhao and Jinrong Bai. Paratypes: 1 female, Jianfengling, Ledong, Hainan, 3 June, 2010, collected by Ming Qiu and Ruilian Li; 2 females, Jianfengling, Ledong, Hainan, 25 May, 2011, collected by Lehong Zhao and Jinrong Bai.
Distribution. China (Hainan).
Measurements (mm). BL: 3 25.0, ♀ 24.0–29.0; PL: 3 6.0, ♀ 6.0–7.0; HF: 3 15.0, ♀ 14.0–17.0; TL: 3 32.0, ♀ 31.5– 34.5; Ov: ♀ 26.0–30.0.
Discussion. The new species is similar to Diaphanogryllacris incavatis Du, Bian & Shi, 2016, but differs from the latter in: male ninth abdominal tergite constricted in the middle, forming 1 transversal fold and 1 foveola (Fig. 2 G); basal area of processes of male tenth abdominal tergite arch shaped in apical view, centra slightly inflated outward; apical spines of the processes compact, inserted the foveola of ninth abdominal tergite (Fig. 2 G–H).
Etymology. The name of the new species is derived from the morphology of ninth abdominal tergite.
