Mao, Shao-Li & Shi, Fu-Ming, 2007, A review of the genus Leptoteratura Yamasaki, 1982 (Orthoptera: Tettigoniidae: Meconematinae) from China, Zootaxa 1583 (1), pp. 37-42 : 40-42

( Figs. A–B, 1–9 )

Holotype. Body small and delicate. Head flattened dorsally, fastigium of vertex flattened, anterior margin almost truncate. Compound eyes hemispherical, protruding anterior-laterally. Apical segment of maxillary palpi much shorter than subapical one, distally strongly inflated, trumpet-shaped. Disc of pronotum almost flat, anterior margin of pronotum slightly concave, posterior margin angularly rounded. Lateral lobes of pronotum longer than high (length 1.5 mm, height 1.0 mm), humeral sinus almost absent. Thoracic foramen elliptical small, completely free. Tegmina long, distinctly surpassing apices of posterior femora. Hind wings slightly longer than tegmina. All femora unarmed. Anterior coxa with one blunt spine; tibial tympana open on both sides, with 3 internal and 2 external spines and a pair of distal spurs on ventral margins, internal basal spine rather small. Posterior tibiae with 23 to 27 spines and one pair of distal spurs on both dorsal margins, ventral margins with 7 external spines and 3 internal spines and one pair of distal spurs. Tenth abdominal tergite with concave posterior margin. Cerci symmetrical, spatulate, strongly curled, with some rather thin dense teeth on ventro-internal side, dorsal side bearing a small distal strumae. Subgenital plate comparatively small, styli rather short. Genitalia entirely membranous.

Female. Body similar to male. Cerci conical, slightly thin at base, acuate at apex. Subgenital plate swelled, posterior margin with medial notch. Ovipositor curved dorsad, ventral valves apices with small hooks.

Coloration. Body green when alive, light yellow in preserved specimens. Compound eyes brown. Tegmina with sparse light brown spots. Apices of tarsi light brown.

Type materials. Holotype: male, China: Dashahe, Daozhen , Guizhou Province, 19 Aug. 2004, collected by Shi Fu-Ming. Paratype: 1 male, 3 females, other data same to holotype; 1 male, 1 female, 20 Aug. 2004; 1 male, 21 Aug. 2004, other data same to holotype.

Measurements (in mm). Length of body: ♂ 7.5–8.0, ♀ 7.8–8.0; Length of pronotum: ♂ 3.1–3.2, ♀ 2.7; Length of tegmina: ♂ 9.5–10.0, ♀ 10.5–11.0; Length of hind femora: ♂ 5.7–6.3, ♀ 6.7–6.9; Length of ovipositor: 4.0–4.2.

Derivation of name. This new name refers to the morphology of the male’s cerci.

Discussion. This new species resembles Leptoteratura (Rhinoteratura) borneoensis Jin, 1995 and Leptoteratura (Rhinoteratura) sharovi Gorochov, 1993 , but differs in: (1) male cerci lamellate, strongly curled; (2) male subgenital plate with slightly concave posterior margin; (3) female subgenital plate inflated.

In addition, according to the original description and diagnostic figures of Leptoteratura symmetrica Yamasaki, 1988 : cerci symmetrical, anterior margin of fastigium of vertex almost truncate and so on, we transfer it to subgenus Rhinoteratura .
