TYPE MATERIAL. Holotype – ♂, China: Yunnan province, Nabanhe N. R.,

Bangganghani, 2200–2300 m, 29.IV 2009, leg. Jia-Yao Hu & Zi-Wei Yin ( SEM).

Paratypes: 1♂, 2♀, the same data as the holotype ( SEM) .

view; 2 – male abdominal apex, dorsal view; 3 – male genitalia, dorsal view; 4 – female abdominal apex, ventral view; 5 – female abdominal apex, lateral view. Scale bar = 1mm.

DESCRIPTION. MALE. Body small, shinning. Head with fastigium of vertex divided into two conical tubercles, completely fused. Legs slender; fore femur about 1.3 times as long as the pronotum, beneath unarmed, external genicular lobe with a long movable spine; fore tibiae beneath with 2 external and 2 internal movable spines, between the paired apical spurs with a short spur. Mid femur with a long movable spine on the external and internal genicular lobe; mid tibiae beneath with 2

external and 1 internal movable spines, between the paired apical spurs with a short spur. Hind femur beneath with 5–6 external small spines and without external spines;

hind tibiae above with 50–54 outer spines and 45–49 inter spines, inner supra apical spur of hind tibiae slightly longer than the hind metatarsus. Hind metatarsus with 2–3

dorsal spines, including the apical spine. Posteromedian process of 6th abdominal tergite with a truncated apex, reaching the apex of 7th abdominal tergite, its apex obviously wider than apex of 6th abdominal tergite ( Figs 1, 2 ). Male genitalia:

dorsolateral lobes short, dorsomedian lobe broad with lingua-like apical part ( Fig.

3).

FEMALE. Subgenital plate transverse, at middle part of hind margin with a small projection ( Fig. 4 ). Ovipositor shorter than the half of hind femur; upper valve of ovipositor without dorsal notch near apex ( Fig. 5 ).

COLORATION. Body dark brown, shinning. Tergites with a greyish white band,

the length of band is variable in different specimens. Frons light, with four dark longi-

tudinal bands from vertex to clypeus. Legs dark brown, without obvious stripes.

MEASUREMENTS (length in mm). Body: ♂ 8.0–10.0, ♀ 8.5–10.0; pronotum:

♂ 4.5–5.0, ♀ 4.5; fore femora: ♂ 6.0–6.5, ♀ 5.5–6.0; hind femora: ♂ 13.0–13.5, ♀

missing femora; hind tibiae: ♂ 13.5–14.5, ♀ missing tibiae; ovipositor ♀ 6.0–6.5.

DIAGNOSIS. The new species is similar to Tamdaotettix (Laotettix) curvatus

Gorochov et Storozhenko, 2015, but differs from the latter in the male posteromedian process of 6th abdominal tergite with a truncated apex, which reaches apex of process of 7th abdominal tergite, but the process of 7th tergite obviously wider than the former ( Figs 1, 2 ) (in T. curvatus , the process of 6th abdominal tergite with blunt apex, process of 7th abdominal tergite with concave apex, apex of 6th tergite process not reaching apex of 7th tergite process).

DISTRIBUTION. China (Yunnan).

ETHYMOLOGY. This species is named after a truncated apex of male posteromedian process of 6th abdominal tergite.
