Lateral lobes of metasternum distinctly separated. WINGS. Tegmina fully developed, reaching or hardly surpassing apex of hind femora, about 5.20–5.58 × as long as broad; medial area broad, as broad as costal area, and broader than subcostal and cubital areas; all areas with intercalary veins; hind wing as long as tegmina. LEGS. Hind femora moderately robust, about 3.96–4.08 × as long as broad, with upper median carinae extremely weakly serrated and dentate apically ( Fig. 2K ); both inner and outer lower genicular lobes sharply angulate. Hind tibiae with 8 spines each at inner and outer margins; external apical spine absent; hind tarsi with large arolium exceeding ½ of claws. Tympanum developed, with oval aperture. Tergite of 10 th abdominal segment split in middle, with pair of small furculae. Supra-anal plate long pentagonal, mid part longitudinally convex and sulcate overall length, with sulcus broad and deep at basal half and narrow and shallow at apical half; lateral margins sinuate, with basal ⅔ roundly convex and tapered at apical third; posterior margin blunt-angularly protruding. GENITALIA. Cerci elongate and conical, with apex curved downwards in lateral view, and short tooth at inner side near apex in dorsal view. Subgenital plate elongate conical, apex distinctly constricted and little pointed. Epiphallus bridge-shaped, not divided into two symmetrical halves; bridge narrow, lophi large, nearly square, and vertically projecting upwards; ancorae large and elongate, curved to ventral and inner sides; anterior projections indistinct and lateral plates concave in middle portion; phallic complex with valves of cingulum longer than apical valves of penis in lateral view and fused apically, and apical valves of penis invisible in dorsal view; cingular apodeme and zygoma very narrow; ectophallus bearing at ventral surface additional pair of cystiform sclerites.

Mostly black, with four broad longitudinal strips of bright yellow color, one pair extending from dorsum of head inside eyes through lateral sides of pronotum to cubital area of tegmina ( Fig. 1A ), and another pair extending from genae below eyes to anterior half of mesopleurite ( Fig. 1B ). Mandibles black apically and yellow basally; labrum with central and posterolateral areas yellowish brown and remaining portion dark brown ( Fig. 1C ), or completely dark brown ( Fig. 3F ); clypeus and frons mostly yellow but black at frontal ridge above median ocellus and at both sides of frontal ridge below median ocellus ( Fig. 1C ), or in some individuals mostly black with frontal ridge yellow below median ocellus ( Fig. 3F ); tubercles below eyes black; fastigium brown or yellow. Antennae yellow at basal third and apical four or five segments and other antennomeres black.

Female Similar to male in body shape and coloration. Eyes with longitudinal diameter 1. 39–1.43 × of transversal diameter and 1.82–1.90 × of subocular sulcus. Interocular distance about 0.71–0.75 × of width of frontal ridge between the antennal sockets. Antennae reaching basal forth of hind femur, with median segments 3.65–3.68 × as long as broad. Pronotum with only posterior transverse sulcus interrupting median carina, and prozona about 1.34–1.50 × of metazona. Lateral lobes of mesosternum with maximum width about 1.35–1.38 × of length. Mesosternal interspace about 1.17 × as long as its minimum width. Tegmina about 5.09–5.13 × as long as broad. Hind femora about 3. 69 × as long as broad. Supra-anal plate triangular, with broad and shallow longitudinal sulcus at basal half and U-shaped carina at the middle. Subgenital plate broad at middle portion and posterior margin protruding triangularly. Ovipositor valves robust, apex hook-like and pointed; dorsal valves armed with few large blunt teeth at external edge of dorsal side. Body color similar to male but with little variation in some individuals ( Fig. 2E–2J ). Abdomen mostly black to blackish brown with some yellowish patches at lateral sides of tergites ( Fig. 2M ) and around lateral and posterior margins of 5 th to 7 th ventrites ( Fig. 2N ). Distribution This species is known from North ( Chiang Mai , Nan ), East (Khao Yai National Park) and West (Dawna Hill) Thailand ( Laosinchai & Jago 1980 ), and from Yunnan Province of China . Remarks According to the original description and after a careful comparison of the types and additional materials of the two species, no distinct difference is found between them and they should be conspecific. Because Pseudotraulia cornuata was published earlier and has the priority, Bannacris punctonotus is herein considered as a junior synonym of the former.
