Description. Male. Body is larger than other species of the genus Tamdaotettix . Fastigium verticis divided into two conical tubercles, drawn together, apices directing forward and downward ( Fig. 1 A View FIGURE 1 ). Lateral ocelli large, nearly spheroidal, situated on lateral margins of conical tubercle of fastigium verticis; median ocellus smaller than lateral ocelli, oval, located between antennal sockets. Eye oval, obviously protruding forward. Anterior margin of pronotum rather straight, posterior margin protruding ( Fig. 1 D View FIGURE 1 ), posterior margins of lateral lobes slightly concave, ventral margins arcshaped; posterior margin of mesonotum protruding, posterior margins of lateral lobes slightly concave, ventral margins arc-shaped; posterior margin of metanotum protruding, ventral margins of lateral lobes oblique ( Fig. 1 B View FIGURE 1 ). Fore coxae absolutely inflated, with 1 spines; apices of femora with 1 outer spine; inner margin of ventral surface of tibiae with 2 spines, outer margin with 2 spines, subapices with 1 ventral spine, with 1 pair of dorso-apical spines and 1 pair of ventroapical spines. Apices of femora with 1 pair of spines; inner margin of ventral surface of tibiae with 1 spine, outer margin with 2 spines, subapical area with 1 ventral spine, with 1 pair of dorsal apical spines and 1 pair of ventral apical spines. Inner margin of ventral surface of hind femora with 7 spines; inner margin of dorsal surface of tibiae with 42–44 spines, outer margin with 46–47 spines, spines arrange in groups, subapical area with 1 pair of dorsal spines, with 1 pair of dorsal apical spines and 2 pairs of ventral apical spines, inner dorsal spine slightly longer than hind basitarsi; dorsal surface of hind basitarsi with 4 spines ( Fig. 1 I View FIGURE 1 ). Ventral surface of fore, middle and hind tarsi with numerous bristles. Posteromedian process of sixth abdominal tergite nearly triangular, basal area slightly broad, gradually narrowing, apex acute, absolutely longer than posteromedian process of seventh abdominal tergite ( Fig. 1 C View FIGURE 1 ). Base of posteromedian process of seventh abdominal tergite broad, the middle of posterior margin of posteromedian process obviously protruding backward, apex rounded ( Fig. 1 C, E View FIGURE 1 ). Basal half of paraproct broad, middle area slightly narrow, apical area expanded, posterior margin truncate ( Fig. 1 H View FIGURE 1 ). Cerci slender and long, conical, apices acute ( Fig. 1 G–H View FIGURE 1 ). Base of subgenital plate broad, gradually narrowing, posterior margin arc-shaped ( Fig. 1 F View FIGURE 1 ).

Female. Body is similar to male. Posteromedian process of seventh abdominal tergite slightly protruding ( Fig. 2 D View FIGURE 2 ). Cerci slender and long, conical, apices acute ( Fig. 2 D–E View FIGURE 2 ). Ovipositor rather short, slightly curved dorsally, apical area of dorsal surface of dorsal valvulae with 1 incision, apical area of ventral surface of ventral valvulae denticulate ( Fig. 2 D– E View FIGURE 2 ). Base of subgenital plate broad, semi-circular, apex rounded; each side of the base with 1 small lobe ( Fig. 2 F View FIGURE 2 ).

Coloration. Body yellowish-brown. Apical area of labial palpi and spines of legs black, lateral lobes of pronotum with light yellow spots, tergites of thorax and first abdominal tergite shining, tibiae of legs with yellow spots, lateral margins of hind femora with light yellow stripes, basal half of cerci light yellow.

Material examined. Holotype: male, Pinglongshan, Fangchenggang , Guangxi, 28 June, 2015, coll. Dongxiao Zhang . Paratypes: 1 female, Pinglongshan, Fangchenggang , Guangxi, 26 June, 2015, coll. Dongxiao Zhang ; 1 female, Pinglongshan, Fangchenggang , Guangxi, 3 July, 2015, coll. Dongxiao Zhang .

Measurements (mm). Body: ♂ 17.8, ♀ 16–17.5; pronotum: ♂ 7.0, ♀ 6.9; fore femora: ♂ 10.9, ♀ 9.5; hind femora: ♂ 23.0, ♀ 20–21; hind tibiae: ♂ 23.8, ♀ 20.2–21; hind basitarsi: ♂ 4.0, ♀ 3.9–4.2; ovipositor: 7.9–8.8.

Distribution. China (Guangxi).

Discussion. The new species differs from Tamdaotettix (Tamdaotettix) dilutus Gorochov by: posteromedian process of male sixth abdominal tergite absolutely longer than posteromedian process of seventh abdominal tergite; base of posteromedian process of seventh abdominal tergite broad, the middle of posterior margin of posteromedian process obviously protruding backward, apex rounded; apical area of paraproct expanded, posterior margin truncation.

Etymology. The name of the new species is derived from posteromedian process of male sixth abdominal tergite absolutely longer than posteromedian process of seventh abdominal tergite, Latin long - means long, with the Latin tuber - means tuber.
