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 (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, 13D, 18). Eyes in dorsal view globular and slightly protruding anteriorly (Fig. 9N). Head dorsum dark purple except posterior end (Fig. 9N). Frontal rostrum somewhat flattened, triangular, stout, with rounded apex and median sulcus indistinct (Fig. 9N). Antennal scapus green; pedicles with a tint of purple; and segments reddish purple (Figs 9N, 9O). Face and mouthparts generally of light colour, median ocellus large and pyriform (Fig. 9O). Below eye between gena and frons with a purple triangular band (Figs 9M, 9O). Pronotal disc with anterior margin straight, posterior margin broadly rounded (Fig. 9N); pronzona 1.8 times longer than metazona. Pronotal lobe 1.2 times taller than long; ventral margin short and rounded (Fig. 9M). Tegmen relatively narrow and unicolourous dark green (Fig. 13D). Legs generally green, femora with a tint of purple; hind femur mostly purple except at base (Fig. 18). Fore tibia with inner tympanum conchate, slightly swollen, with broad slit opening, around tympanum and knee with a tint of purple (Fig. 10L); with outer tympanum pyriform, slightly narrow (Fig. 10M). Hind femur with genicular area purple; with external lobes bispinose, both spines acute (Fig. 10N).
Male. Left tegmen with vein 1A swollen, typical for genus, transversely pyriform with anal end distinctly narrower (Fig. 11I); right tegmen with vein 1A sinuous and mirror squarish with basal and distal margins oblique and lateral margins slightly curved (Fig. 11J). 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). Abdominal apex as shown in Fig. 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.
Ecology. This species was attracted to light. It is probably an arboreal species.
Distribution. Borneo (Mount Trus Madi in Sabah)
