Paratype: 1 male (KB.17.01), same locality as holotype, N4.54719, E115.15713, 76.5±9.0 m a.s.l., under foliage of tree, 5 January 2017, 1952 hours, coll. M. K. Tan (in ethanol, ZRC).

Description. Male (holotype). Eyes large, almost globular ( Figs. 4 ; 5A, B). Frontal rostrum conical, stout, with rounded apex of upper tubercle having median sulcus feebly present ( Fig. 5B ). Apical segment of maxillary palpus barely longer than subapical (fourth) segment, slender and slightly widened apically ( Fig. 5A, 5B ); fourth and third segments of this palpus subequal in length ( Fig. 5A ). Pronotum covering most part of tegminal mirror ( Fig. 5B ); pronotal disc roundly turned into lateral lobes, transverse sulcus distinct but very shallow; dorsal edge of pronotum almost straight in profile ( Fig. 5A ); anterior margin of pronotal disc straight, posterior margin angularly rounded ( Fig. 5B ); ventral margin of pronotal lateral lobe short and almost straight. Thoracic auditory spiracle (= thoracic foramen) small, slender and pyriform; not covered by pronotal lateral lobe. Tegmen rather narrow, with narrowly rounded apex, reaching middle part of hind tibiae; hind wing reaching tegminal apices ( Figs. 4A, 4B ). Femora without spine; fore tibiae each with 3 outer and 3 inner subapical spines; middle tibiae each with 4 outer and 3 inner subapical spines; inner and outer knees of hind femora with triangular lobes not spine-like but having subacute apices; hind tibiae ventrally and dorsally with numerous outer and inner spines as well as 2 ventral and 1 dorsal apical spurs on each side. Tenth abdominal tergite and epiproct as in Figs. 5C, 5D . Cercus slightly incurved, with middle part having almost keel-like (lamellar) but rather short dorsal process and finger-like medial (ventral) process ( Figs. 5C–F ); dorsal process with higher and almost angular anterior lobe ( Fig. 5F ); ventral process slightly flattened ( Figs. 5C, 5D ); apical third of cercus lamellar, tapering into obtuse apex, with dorso-interior margin almost straight and more strongly sclerotized ( Figs. 5D–G ). Subgenital plate longer than broad; its anterior part almost 3 times as wide as posterior one; posterior part of this plate with almost parallel lateral margins; styli located at apex of subgenital plate as in Figs. 5E, 5G .

Colouration. Generally green when alive ( Fig. 4A ). Head pale green to green, with tint of yellow brown on fastigium, antennal scapus and pedicel. Frontal rostrum dark green. Eyes dark red brown. Maxillary palpus with small subapical spot blackish. Pronotum green, disc with a pair of dark green spots at the anterior margin and in the middle, with a brown median longitudinal line at the apical third and a triangular black spot on either side of the band; the area of pronotal disc between these dark marks brownish grey; lateral lobe with two dark green spots near ventral margin ( Fig. 4B ). Tegmen with numerous large black spots. Legs generally pale green; tarsi and apex of tibiae black. Spines on legs mostly black; tympanal region and knees (especially so for fore and hind legs) dark. Abdomen green to yellow green dorsally, sternite pale green; some tergites have dark green transverse band.

Female. Unknown.
