Fig. 1 , Map 1

Description. Male. Body small, comparatively large-sized for the tribe Meconematini . Fastigium verticis conical, apex rounded, dorsal surface with a longitudinal sulcus. Eyes ovoid, distinctly protruding forwards. Apical segment of maxillary palpus almost equal to subapical one, apex slightly inflated. Anterior margin of pronotum rather straight, posterior margin rounded; lateral lobe longer than high, humeral sinus very weak. Tegmina long, obviously surpassing apices of hind femora, apices rounded; hind wings longer than tegmina. All femora unarmed. Fore coxae with a spine; bases of tibiae expanded, tympana open on both sides, ventral surface of fore tibiae with 5 spines on internal margin and 6 spines on external margin, basal spines longer while apical spines much shorter. Ventral surface of middle tibiae with 5 spines on internal margin and 6 spines on external margin. Dorsal surface of hind tibiae with 32–36 spines on internal margin and 41–42 spines on external margin, 1 pair of dorsal apical spurs and 2 pairs of ventral apical spurs. Base of tenth abdominal tergite broad, the middle of posterior margin with a pair of posterior processes, the basal half slightly broad, internal margins nearly parallel, with narrow cleft between inner margins; the apical half gradually narrowing, curved ventro-outwards, apices with a pair of spine-shaped processes which are similar in morphology and length, directing interio-ventrad, apices acute. Basal half of cerci rolled, barrel-shaped, with a spine-shaped process on internal margin near the base, curved dorso-inwards, apex acute; external margin with a dumpy and conical process near the base; apical half of cerci obviously curved dorsoinwards, slender and long, spine-shaped, apices acute. Base of genitalia broad, almost rectangular, the middle part slender, ventral surface of which with a pair of triangular and lobe-shaped processes; subapical area of genitalia with a lateral process separately; apices with lateral and ventral margins expanded slightly, trifoliate in dorsal view, sclerotized, edges with thin teeth; dorsal surface expanded, semilunar, sclerotized. Subgenital plate longer than broad, nearly rectangular, posterior margin slightly protruding; styli slender and long, apices rounded.

Coloration. Body yellowish brown. Eyes light brown. Lamellate eminentia of internal margin of antennal socket blackish brown, scape and pedicel with blackish brown spots, flagellum with ring blackish brown stripes. Apical area of the fifth maxillary palpus light brown. Anterior areas of tegmina with a row of circular brown spots, stridulatory area light brown, exposed area of hind wings brown. Dorsal spines of hind tibiae light brown, tarsi of 3 pairs of legs brown. Spine-shaped processes of apices of posterior processes of tenth abdominal tergite brown. Apices of cerci brown, apex of the process on internal margin near the base brown. A pair of processes on ventral surface of genitalia brown.

Female. Unknown.

Material examined. Holotype: male, Nabang, Yingjiang , Yunnan, 12 September, 2015, coll. Yu-Tang Wang . Paratypes: 2 males, Nabang, Yingjiang , Yunnan, 12 September, 2015, coll. Yu-Tang Wang .

Measurements (mm). Body: ♂ 11.4–12.4; pronotum: ♂ 4.3–5.0; tegmina: ♂ 19.0–20.1; hind femora: ♂ 13.6– 14.6.

Discussion. The new species is similar to Kuzicus (Kuzicus) koeppeli Sänger & Helfert, 2004 , but it differs from the latter in male by: apices of posterior processes of tenth abdominal tergite with a pair of spine-shaped processes; apical half of cerci spine-shaped, slender, nearly aequilate, apices acute, obviously curved dorsoinwards; genitalia obviously different ( Fig 1 . G).

Etymology. The name of the new species is derived from the morphology of male cerci, Latin lept- means gracile, with the Latin cerc- means cerci.
