Material examined. EAST MALAYSIA: Sabah State • ♂ holotype; Mount Trus Madi, Trusmadi Entomology Camp ; N5.44174, E116.45074, 1189.0± 5.2 m.a.s.l.; 31 October 2023, 22h45; attracted to light trap at ridge; coll. M.K. Tan, J.L. Yukang & A.Y.C. Chung; SBH.23.56 GoogleMaps ( FRC)

Etymology. The species name refers to the depressed male tenth abdominal tergite with carinated margins, cratera = crater in Latin.

Diagnosis. The new species is characterised by the combination of the following male characters: the tenth abdominal tergite is trapezoidal, depressed with its lateral and posterior margins carinated. Its subgenital plate forms a shaft with straight lateral margins; the apical lobes are very narrowly spaced. Its styli are flattened and about as long as the apical lobe.

Description. Habitus typical for genus; medium in size compared to congeners; head, pronotum and tegmina generally dark green with legs with a tint of dark purple when alive, yellow when preserved ( Figs 9M, 9N View FIGURE 9 , 13D View FIGURE 13 , 18 View FIGURE 18 ). Eyes in dorsal view globular and slightly protruding anteriorly ( Fig. 9N View FIGURE 9 ). Head dorsum dark purple except posterior end ( Fig. 9N View FIGURE 9 ). Frontal rostrum somewhat flattened, triangular, stout, with rounded apex and median sulcus indistinct ( Fig. 9N View FIGURE 9 ). Antennal scapus green; pedicles with a tint of purple; and segments reddish purple ( Figs 9N, 9O View FIGURE 9 ). Face and mouthparts generally of light colour, median ocellus large and pyriform ( Fig. 9O View FIGURE 9 ). Below eye between gena and frons with a purple triangular band ( Figs 9M, 9O View FIGURE 9 ). Pronotal disc with anterior margin straight, posterior margin broadly rounded ( Fig. 9N View FIGURE 9 ); pronzona 1.8 times longer than metazona. Pronotal lobe 1.2 times taller than long; ventral margin short and rounded ( Fig. 9M View FIGURE 9 ). Tegmen relatively narrow and unicolourous dark green ( Fig. 13D View FIGURE 13 ). Legs generally green, femora with a tint of purple; hind femur mostly purple except at base ( Fig. 18 View FIGURE 18 ). Fore tibia with inner tympanum conchate, slightly swollen, with broad slit opening, around tympanum and knee with a tint of purple ( Fig. 10L View FIGURE 10 ); with outer tympanum pyriform, slightly narrow ( Fig. 10M View FIGURE 10 ). Hind femur with genicular area purple; with external lobes bispinose, both spines acute ( Fig. 10N View FIGURE 10 ).

Male. Left tegmen with vein 1A swollen, typical for genus, transversely pyriform with anal end distinctly narrower ( Fig. 11I View FIGURE 11 ); right tegmen with vein 1A sinuous and mirror squarish with basal and distal margins oblique and lateral margins slightly curved ( Fig. 11J View FIGURE 11 ). Stridulatory file on left tegmen stout, typical for genus; straight with ca. 31 fairly widely-spaced and stout teeth and additionally 6 additional smaller stout teeth at basal end ( Fig. 12E View FIGURE 12 ). Abdominal apex as shown in Fig. 19 View FIGURE 19 : tenth abdominal tergite trapezoidal, depressed with its lateral and posterior margins carinated; laterally produced into large, setose triangular lobe covering cercus. Subgenital plate forms a shaft with straight lateral margins; apical lobes very narrowly spaced. Styli about as long as apical lobe, flattened.

Female. Unknown.

Measurements (♂ holotype, in mm). BL = 16.6; BWL = 44.4; PL = 5.0; PW = 3.6; TL = 34.9; TW = 6.9; HWT = 5.3; HFL = 26.2; HFW = 3.2; HTL = 30.3.
