Figs. 2–11

Description. Male ( Figs. 2, 3 ). Body medium sized, depressed dorso-ventrally. Head small, nearly globular; occiput projecting; frontal rostrum convex, scapus peltate, almost 1.5 times as wide as frontal rostrum; median ocellus located on dorsum of frontal rostrum; lateral ocelli obsolescent; eyes small sized, oval, slightly projecting; apical joint of maxillary palpus widened and sloping apically, almost 1.2 times as long as third joint; labial palpus short, apical joint stick-like, almost 1.5 times as long as second joint. Pronotum distinctly transverse, width about 1.6 times as long as length; anterior margin narrow, concave in middle; posterior margin almost straight; lateral margin arc-shaped and lamellar; disc concave in the middle, anterior and lateral margin irregular, with a pair of small pits at center of the concavity; lateral lobe nearly semicircular, concave in the middle, equipped with a ridge along margin. Metanotal gland developed ( Fig. 6 ), rounded, middle with fine pubescence. Tegmina distinctly extending apex of abdomen, dorsal area distinctly wide, with 6 oblique veins; mirror large, with 3 dividing veins; hind wings longer than tegmina. Legs slender, transverse sections of all tibia quadrangular; fore tibia with a small, oblong internal tympanum, without external tympanum; hind tibia with two rows of numerous short denticles along upper side; hind tibia with 6 spurs at apex, dorsal apical spurs longest.

Supra-anal plate wider than long ( Fig. 7 ), almost width 1.4 times as long as length; posterior margin widen and rounded. Half of subgenital plate spindle-like. Genitalia ( Figs. 8–11 ): epiphallus narrow, with a small membranous window, posterior margin with a very small distinctly emarginated in middle; two pairs of ectoparameres, outer pair slightly thick with blunt apices, not extending apex of epiphallus; inner pair large and curved outwards, with several large teeth along inner margins.

Female ( Figs. 4, 5 ). Body decidedly small. Pronotum transverse, almost width about 1.5 times as long as length; anterior margin equal to the length of posterior margin. Tegmina extending apex of abdomen, with 2 oblique veins in lateral area. Hind wings slightly extending apex of abdomen, and shorter than tegmina. Ovipositor sword-like.

Coloration. Body black brown. Eyes brown. Tegmina brown, with several irregular spots or stripe.

Measurements(mm). Male: Body length 19.0–21.0, length with wings 29.0–30.0, pronotum 4.0–4.5, tegmen 21.0–25.0, hind femur 11.0–11.9. Female: Body length 13.1, length with wings 22.0, pronotum 4.5, tegmen18.0, hind femur 13.0, ovipositor 9.2.

Type material. Holotype ♂: CHINA: Guangxi, Chongzuo , white-headed langur national natural reserve ( Fig. 12), 14-VI-2016, leg. Zhi-Lin Chen . Paratypes: 2♂ 1♀, same data as the holotype .

Diagnosis. This new species is related to Cacoplistes (Laminogryllus) choui Liu & Shi , but differs from the latter by: the epiphallus distinctly narrowed; outer pair of ectoparameres short, not extending apex of epiphallus, and with blunt apices.

Distribution. China (Guangxi).

Etymology. This new specific name is derived from Latin brevis (short) + paramerus (paramere), a reference to outer pair of ectoparameres short.
