Male description. Habitus as shown in Figs. 2, 3A. Vertex with faint middle keel (Fig. 3B). Dorsally, fastigium narrow, 1.3 times as long as wide, slightly enlarged at the apex; separated from vertex by a transverse furrow (Fig. 3B). Frons narrow between antennal scapes with lateral keels sinuously converging dorsally, diverging ventrally (most far apart) between scapes before converging ventrally (Fig. 3C). Frontal costa with faint lateral keels (Fig. 3C). Scapus elongated, antenna with 11 segments; segment flattened, tend to widen apically (Fig. 3D). Pronotal dorsal disc with anterior margin broadly concave and posterior margin obtuse, rounded; with transverse furrow continuing to lateral lobe. Pronotal lateral lobe with anterior margin convex; ventral margin straight in anterior half and oblique in posterior half; ventro-posterior angle 90°; posterior margin straight. Tegmina and hind wings well surpassing beyond apex of hind femora and abdominal apex (Fig. 3D). Tegmina with fine veining and delimiting fairly large areoles; slightly curved back at apical part, at the apex subacutely-rounded (Fig. 3E). Hind wings 2.0 times as long as wide (Fig. 3E). Hind tibia armed with 20–22 external and 14–15 internal spines.
Abdomen enlarged apically (Fig. 1). 8 th tergite normal, with lateral portion extending posteriorly into a narrow lobe with truncated apex (Fig. 1A). Central portion of 9 th tergite elongated, narrow slightly after basal third and forming a shaft-like process, apex bilobed with apices of lobes narrow, round and pointing externally (Fig. 1B). Lateral portion of 9 th tergite fused to 10+12 th tergites with distinct suture; lateral portion forming three lobes: ventral lobe triangular and pointing posteriorly with subacute apex, middle lobe more narrow and elongated, separated from ventral lobe by deep and wide excision, dorsal projection longest and narrowest, pointing dorsad (slightly curved posteriorly in the middle) with lamellate and truncated apex (Fig. 1A). 10 th and 12 th tergites, although united, clearly delimited (Fig. 1B). 10 th tergite in dorsal view producing two lateral posterior process with subacute apex, slightly diverging from one another at apex (Fig. 1B). 12 th tergite forming tongue-shaped supra-anal plate. Cercus very long and U-bent; basal part slightly less than twice as long as apical part, slightly narrowed towards apex (in dorsal view) (Fig. 1B), although in lateral view, it has parallel margins (Fig. 1A); the apical part pointing anteriorly (parallel to basal part), narrower than basal part, chitinised, somewhat compressed and very sharp towards the apex (Fig. 1B). Subgenital plate with deeply V-excised basal margin; in the middle with narrow furrow along midline; posterior end bilobed, V-excised (not as deep as basal margin) between the lobes. Apical lobe of subgenital plate rectangular in vento-posterior view, slightly longer than on the posterior margin and converging apically, apex truncated.
Colouration. Generally yellow with tint of green when alive (Fig. 2), green colouration lost when dry-preserved (Fig. 3A). Head with vertex mottled dark and lateral keel yellow; fastigium sometimes lighter in colouration at apex. Eyes white when alive (Fig. 2), brown when dry-preserved, with numerous vertical dark stripes (Fig. 3D). Scapus yellow green, antennal segments brown to dark brown (Figs. 3B, 3D). Labrum green in dorsal half and mottled dark in ventral half. Maxillary palps grey green with brown rings. Pronotal dorsal disc generally grey (dark when drypreserved) with anterior margin brown; lateral lobe yellow green with tint of blue grey (Figs. 2, 3D). Tegmina with dark brown veins; cells completely hyaline, apex with trace of brown (Fig. 3E). Anterior and middle legs generally yellow green to green with brown spines. Hind femora generally yellow green, basal parts more green, apical part more yellow with brown knees (Figs. 2, 3A). Hind tibia and tarsus grey. Thoracic tergites grey yellow, abdominal tergites yellow with tints of green (Fig. 2). Lateral parts of 9 th tergite with apices of processes dark. Cercus apical half brown with black apex (Fig. 1).
Measurements (in mm). BL = 15.6, PL = 2.1, FWL = 12.2, HWL = 11.5, HFL = 9.1, HFW = 2.3, HTL = 8.7, HTaL = 3.9.
Female (Fig. 4). Newly acquired specimens match the original female description: FW with two brown oblique bands, narrowly and imperfectly marked, in its apical third (Fig. 4B). Wings being 2.4 times as long as wide (Fig. 4B). Abdominal apex with a dorsal tongue-shaped plate with lateral margins emarginated in the middle. Subgenital plate elongated shaft, narrow at the base, widening until basal third, lateral margins parallel; narrowed angularly near the apex into a narrow and truncated apex (Fig. 4D). Ovipositor as shown in Fig. 4E.
