Legs long and slender; fore femora about 1.5 times as long as the pronotum, beneath unarmed, external genicular lobe with a long movable spur; fore tibiae beneath with 2 external and 2 internal spurs, between the paired apical spurs with a short spur. Mid femora with a long movable spur on the external and internal genicular lobe; mid tibiae beneath with 2 external and 1 internal spur(s), between the paired apical spurs with a short spur. Hind femora beneath with 6 inter spines and without outer spines; hind tibiae above with 33–45 outer spines and 28–39 inter spines, inner subapical spur of hind tibiae slightly shorter than hind metatarsus. Hind metatarsus with 3 dorsal spines. Process of 6th abdominal tergite with a small angular projection ( Fig. 1 ). Basal part of 7th abdominal tergite distinctly wider than apex ( Fig. 1 ). Paraproct long and apex with a small angular projection ( Fig. 2 ).

Coloration. Body dark brown. Four anterior tergites shining. Legs light brown, hind femora yellowish brown.

Measurements. (length in mm) Body Ƌ14.0; pronotum Ƌ6.5; fore femora Ƌ10.0; hind femora Ƌ20.5; hind tibiae ♂ 22.0.

Material examined. 1♂, Mt. Bavi, Tonkin, Vietnam, 1941.VII, alt. 800–1000m, collected by A. De . Cooman. Distribution. Vietnam (Tonkin, Vinh Phu).

Discussion. This species is very similar to Tamdaotettix (Tamdaotettix) aculeatus Gorochov, 2015 , but differs from the latter in: process of male paraproct distinctly longer than the rest part of paraproct and with a small angular projection at apex.
