Yukang leg., 11 January 2019 2045 h (FRC). Type locality. EAST MALAYSIA: Sarawak: Kuching Distribution. Borneo (states of Sarawak, Sabah) Male description. Habitus as shown in Fig. 5A. Vertex with faint middle keel (Fig. 6A). Dorsally, fastigium narrow and more elongated, 2.1 times as long as wide, faintly enlarged at the apex; separated from vertex by a very faint transverse keel, apex rounded (Fig. 6A). Frons narrow between antennal scapes with lateral keels straight (Fig. 6B). Frontal costa with lateral keels barely visible (Fig. 6B). Scapus elongated, antenna with 11 segments; segment flattened, tend to widen apically (Fig. 6C). Pronotal dorsal disc with anterior margin strongly concave and posterior margin obtuse, rounded; with transverse furrow continuing to lateral lobe. Pronotal lateral lobe with anterior margin convex; ventral margin straight to faintly sinuous throughout; ventro-posterior angle 90°; posterior margin straight. Tegmina and hind wings surpassing beyond abdominal apex but not apex of hind femora. Tegmina with fine veining and delimiting fairly large areoles; faintly curved back at apical part, at the apex rounded. Hind tibia armed with 22–23 external and 17–18 internal spines. Abdomen enlarged apically (Figs. 7A, 7B). 8 th tergite normal, with lateral portion extending slightly posteriorly (Fig. 7A). Central portion of 9 th tergite elongated, narrow posteriorly until apical third; apical third widens, apex bilobed with apices of lobes broadly round (Fig. 7B). Lateral portion of 9 th tergite large, extend and narrowing posteriorly into a triangular lobe with obtuse apex (Fig. 7A). 10 th tergite in dorsal view tongue-shaped, longitudinally furrowed in the middle (Fig. 7B). 12 th tergite forming lanceolate supra-anal plate with acute apex (Fig. 7B). Cercus bent 90° at apical third; basal part typical of genus; the apical part pointing inwards, lamellate and chitinised, lanceolate with acute apex (Fig. 7B). Subgenital plate with posterior end bilobed, U-excised between the lobes: middle of excision with a small stout lobule, apical lobe of subgenital plate triangular with rounded apex. Colouration. Generally green and yellow when alive (Fig. 5), green colouration lost when dry-preserved. Head more yellow than green, with vertex mottled dark and lateral keel yellow; fastigium yellow (when alive) (Fig. 5). Eyes yellow; with numerous vertical dark stripes (Figs. 5A, 6A–C). Scapus yellow green, antennal segments red brown (Figs. 5A, 6B, 6C). Labrum green in dorsal half and mottled dark in ventral half. Maxillary palps grey green with brown rings. Pronotal dorsal disc generally green with tint of blue grey (dark when dry-preserved) with anterior margin yellow green (Figs. 5A, 6C). Tegmina with dark brown veins; cells completely hyaline, apex with very faint trace of brown. Anterior and middle legs generally green, femora with tint of brown. Hind femora generally yellow green, basal parts more green, apical part more grey, knees with black stripes (Figs. 5A). Hind tibia and tarsus grey. Thoracic tergites green with tint of blue, abdominal tergites pale green dorsally, pale yellow laterally (Fig. 5A). Central and lateral portions of 9 th tergite and 12 th tergite with apices of lobes black. Cercus apical half pale yellow green with black apex (Figs. 5A, 7B). Measurements (in mm). BL = 13.2, PL = 2.1, FWL = 10.3, HFL = 10.0, HFW = 2.3, HTL = 9.4, HTaL = 3.9. Female (Figs. 5B, 6E, 6F, 7C–E). Newly acquired specimens agree with the original description: Tegmina not surpassing apex of hind femur and rounded at apex (Fig. 6E). Wings being 1.9–2.0 times as long as wide (Fig. 6E). Hind femur as shown in Fig. 6F. Subgenital plate smooth, apex with two notches, medial sharp triangle lobule and on each side a rounded lobe, equally prominent but much wider. (Fig. 7E). Ovipositor as shown in Fig. 7D.
