Material examined. Vietnam: Central Vietnam, Bach Ma N.P., (16°12'N, 107°52'E), 12–17.vii.2011, leg. J. Constant & J. Bresseel (I.G. 31.933)— 1 female, 1 male (Brussels RBINS) .

Discussion. The species is already sufficiently described and its systematic position discussed by Gorochov (2003) and Gorochov et al. (2015). It is recognized by the distinctive color pattern. Head with black genae, labrum and mandibles contrasting with brown vertex, and face and pronotum being black with light anterior spot and posterior margin, in combination with the apical spines of the ninth abdominal tergite male being rather long and narrow, faintly curved with acute tip. The female subgenital plate has at base a transverse groove, which at larger magnification appear to consist of two oval pits. These pits obviously serve as a fix point for the male apical spines of ninth abdominal tergite during copulation, as already supposed by Gorochov (2003).

Additional Description. Medium large species. Head: Face ovoid; forehead in middle with fine riffles, laterally nearly smooth; fastigium verticis wider than scapus; ocelli little distinct; fastigium frontis separated from fastigium verticis by a very fine suture; subocular furrows shallow ( Fig. 48H ). Abdominal tergites two and three with few largely reduced, indistinct stridulatory pegs.

Wings surpassing hind knees ( Figs. 46F , 47G ). Tegmen: Radius with two branches, both forked near tip; media anterior arises free from base; cubitus anterior at base with a single branch that forks into two veins, the anterior branch makes a curvature and receives an oblique connection vein from MA and shortly after divides again into two parallel branches, MP and CuA1, while the posterior branch (CuA2) does not divide further; cubitus posterior undivided, free throughout; with 4 anal veins.

Legs: Fore coxa with a spine at fore margin; fore and mid femora unarmed; fore and mid tibiae with four pairs of large ventral spines and one pair of smaller ventral spurs; hind femur with 9–11 external and 8–20 internal spines on ventral margins; hind tibia with spaced spines on both dorsal margins, ventral margins with one pre-apical spine; with 3 apical spurs on both sides.

Coloration. General color brown; pronotum with a broad transverse black band that can be entire or interrupted; legs light medium brown, tarsi darker. Face red brown, ocelli light yellow; genae, labrum, maxillary palpi and mandibles black; clypeus with 2 irregular black bands. Tegmen semi-transparent yellowish, towards base darker; veins yellow; hind wing semi-transparent ochre, main veins yellow or brown, cross veins dark brown or black adorned on both sides by narrow light or dark brown bands.

Male. Eighth abdominal tergite prolonged. Ninth abdominal tergite globular, furrowed in midline, then split and provided at both sides with a large, compressed, curved, acute process, in situ overlapping each other ( Fig. 49D ). Subgenital plate wider than long with diverging lateral margins, surface in middle with a large triangular depression reaching from base to tip, apical margin faintly concave in middle; stout styli almost twice as long as subgenital plate, inserted at apico-lateral angles. Phallus membranous.

Female. Seventh abdominal sternite little larger than preceding sternites. Subgenital plate triangular in general outline with all three angles obtuse; in middle of base with 2 small, black, strongly sclerotised, small grooves ( Fig. 51P ). Ovipositor elongate, very slightly curved in basal third, afterwards straight with slightly converging margins; in apical area margins more strongly narrowing but tip obtuse ( Fig. 51Q ).

Measurements (1 male, 1 female).—body w/wings: male 46, female 45; body w/o wings: male 36, female 40; pronotum: male 6.7, female 7.5; tegmen: male 35, female 32; tegmen width: male 12, female 11.5; hind femur: male 19, female 19; ovipositor: female 22.5 mm.
