Material examined. EAST MALAYSIA: Sabah State • ♂ holotype; Mount Trus Madi, Trusmadi Entomology Camp; N5.44307, E116.45155, 1192.0± 5.6 m.a.s.l.; 31 October 2023, 20h33–20h49; attracted to light trap near camp; coll. M.K. Tan, J.L. Yukang & A.Y.C. Chung; SBH.23.40 (FRC)
Etymology. The species name refers to the characteristic falcated male cercus.
Diagnosis. The new species is characterised by the combination of the following male characters: tenth abdominal tergite with a raised triangle in middle; posterior margin broadly rounded, in middle with two bulbous lobes; the lobes are obtusely rounded; between the lobes narrowly emarginated. Cercus large, flattened and strongly curved, with apex flattened tooth-like, truncated. Subgenital plate broad basally, narrowing in basal third into a narrow shaft with its lateral margins parallel. At the apical end with two lateral lobes; the apical lobes slightly longer than half the length of the subgenital plate; between the lobes broadly and angularly emarginated. Styli are flattened, elongate, with apices rounded.
Description. Habitus typical for genus; medium in size compared to congeners; head, pronotum, tegmina and legs when alive generally green, yellow when preserved (Figs 9G, 9H, 13B). Eyes in dorsal view globular and slightly protruding anteriorly; in frontal view slightly longer (Figs 9H, 9I). Frontal rostrum somewhat flattened, triangular, stout, with rounded apex and median sulcus indistinct (Fig. 9H). Antennal scapus with a tint of pinkish red; pedicles mainly pinkish red; and segments pinkish red (Figs 9H, 9I). Face and mouthparts generally light coloured, median ocellus large and pyriform (Fig. 9I). Pronotal disc with anterior margin straight in middle, posterior margin rounded (Fig. 9H); pronzona 1.4 times longer than metazona. Pronotal lobe 1.2 times taller than long; ventral margin short and rounded (Fig. 9G). Tegmen relatively narrow and unicolourous green (Fig. 13B). Legs generally green. Fore tibia with inner tympanum conchate, slightly swollen, with broad slit opening, around tympanum and knee black (Fig. 10G); with outer tympanum pyriform (Fig. 10H). Hind femur with genicular area green, external lobes bispinose, dorsal spine subacute, ventral spine acute (Fig. 10I).
Male. Left tegmen with vein 1A swollen, typical for genus, somewhat transversely oblong but at anal end slightly narrower (Fig. 11E); right tegmen with vein 1A mostly substraight with basal end faintly curved and mirror bowl-shaped with distal end distinctly shorter than basal end (Fig. 11F). Stridulatory file on left tegmen stout, typical for genus; straight with ca. 30 fairly widely-spaced, equally-spaced and equally-sized teeth and 7 additional smaller stout teeth at basal end (Fig. 12C). Abdominal apex as shown in Fig. 16: tenth abdominal tergite in middle with raised triangle; its posterior margin broadly rounded, in middle with two bulbous lobes; lobes obtusely rounded; between lobes narrowly emarginated. Cercus large, flattened and strongly curved, with apex flattened tooth-like, truncated. Subgenital plate broad basally, narrowing in basal third into narrow shaft with lateral margins parallel. At apical end with two lateral lobes; apical lobes slightly longer than half the length of the subgenital plate; between lobes broadly and angularly emarginated. Styli flattened, elongated, with apices rounded.
Female. Unknown.
Measurements (♂ holotype, in mm). BL = 18.9; BWL = 44.9; PL = 5.4; PW = 3.5; TL = 36.9; TW = 6.3; HWT = 3.4; HFL = 20.2; HFW = 2.4; HTL = 23.4.
