Figs. 47 D–E, 48O, 50C, 51L–M

Material examined. Cambodia: Koh Kong, Tatai , (11°35'13''N, 103°5'50''E), 9–19.x.2016, leg. J. Constant & J. Bresseel (I.G.: 33.345 GTI project)— 1 male (Brussels RBINS) ; Pursat, Phnom Samkos , (12°13'2''N, 102°55'7''E), 15–18.x.2016, leg. J. Constant & J. Bresseel (I.G.: 33.345 GTI project)— 1 female (Brussels RBINS) .

Additional Description. Medium large species. Head: Face ovoid; forehead in middle with fine riffles, laterally nearly smooth; fastigium verticis little wider than scapus; ocelli distinct; fastigium frontis separated from fastigium verticis by a very fine suture; subocular furrows shallow ( Fig. 48O ). Abdominal tergites two and three without stridulatory pegs.

Wings surpassing middle of stretched hind tibiae ( Fig. 47 D–E). Tegmen: Radius with one or two (only left tegmen male) posterior branches, only the radius stem and the last branch 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, the last two with common base.

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.

Coloration: General color light brown; head mostly black, pronotum with black margin extended along fore- and hind margins; genicular areas and tibiae of all legs black; ovipositor black, tip brown. Face black; only ocelli, ventral margin of clypeus, base of maxillary palpi, and labial palpi of light color. Tegmen light yellowish, towards anterior and posterior margins lighter; in subbasal area with a sub-interrupted black ring; hind wing semitransparent white, main veins yellow to brown; cross veins brown.

Male. Ninth abdominal tergite globular, furrowed in midline; at ventro-apical margin on both sides of middle with an acute spine little bent ventrad in subbasal area ( Fig. 50C ). Subgenital plate wider than long, lateral margins strongly convex, apical concave; long and stout styli inserted at apico-lateral angles.

Female. Subgenital plate largely membranous, only rim and apical area sclerotised; apex terminating into two subobtuse cones ( Fig. 51L ). Ovipositor elongate, straight, with slightly converging margins; before tip margins more strongly narrowing, tip subobtuse ( Fig. 51M ).

Measurements (1 male, 1 female).—body w/wings: male 49, female 48; body w/o wings: male 28, female 31; pronotum: male 6.5, female 6.5; tegmen: male 41, female 39; tegmen width: male 16, female 15; hind femur: male 19, female 21; antenna: female 125; ovipositor: female 23.5 mm.

Discussion. The species was so far known from South Cambodia ( Gorochov 2003, Gorochov et al. 2015). The current record increase the known range of the species further North.
