Description. Habitus typical of this genus (Fig. 1 A). Pronotum with hind lobe relatively short but long; posterior margin of this lobe gently rounded and covering entire, sometimes almost entire, tegminal mirror (Figs. 1 B, 1D). Thoracic auditory foramen spiracle vertically elongated, upper half of smaller width than lower half in live specimens. Prosternal process rounded; mesosternal and metasternal lobes rounded (Fig. 1 C). Coxae with lobes, that of middle coxae shorter and with apex more obtuse than hind coxae; fore coxae with long spine on external surface (Fig. 1 B). Tegmina relatively short, reaching or slightly surpassing end of the 6th abdominal tergite; gradually narrowing; apex narrowly rounded. Tegmina about as long as hind wings. Legs with 5 – 7 pairs of short ventral spines on femora, inner spines generally longer than outer spines; hind femora with numerous short ventral spines, denser but shorter in basal half than apical half; 5 pairs of long ventral subapical spines on fore and middle tibiae (Fig. 1 E), spines on fore tibiae generally longer than middle tibiae; with numerous upper and lower spines on hind tibiae.

Male. Stridulatory apparatus of left tegmen as shown in Fig. 2 C; stridulatory file substraight, about 1.5 mm long, with teeth densely and fairly equally distributed; mirror as shown in Fig. 2 C. Tenth abdominal tergite emarginated (Fig. 2 A). Epiproct tongue shaped (Fig. 2 A). Cerci hook, setose, basally exceptionally swollen (Fig. 2 A). Subgenital plate with apex extended into two short lobes, fairly wide and acutely excised in between; with long styles, setose, apex rounded (Fig. 2 B). Genitalia membranous.

Female. Tenth abdominal tergite simple (Fig. 2 D). Epiproct tongue shaped (Fig. 2 D). Cerci simple, conical, setose, with apex pointing (Fig. 2 D). Subgenital plate elongate, gently narrowing to a truncated apex; apex slightly notched (Fig. 2 E). Ovipositor curved, elongate; margins smooth (Fig. 2 F).

Colouration. Body generally green, sometimes tinted pale green in live specimen (Fig. 1 A). Head with eyes dark; antennal flagellum brown to yellow brown; scape green with tint of light brown; fastigium green with tint of light brown; mandibles green; maxillary palpi with apical segments light brown, basal segments more greenish (Figs. 1 A–1D). Pronotum with margins brown, hind lobe darker green near the apex. Tegmina green; with dorsal part green with margins yellow to brown; with diving vein between dorsal and ventral parts sometimes yellow; with lateral part basal area with a big oval yellow spot with irregular red outline; apex increasing yellow to orange, sometimes red in live specimens (Fig. 1 B). Thoracic sternites green, mesosternal and metasternal lobes light blue in live specimens; abdominal tergites generally green to pale green; abdominal sternites bright light blue in live specimens, discoloured in older dried specimens (Fig. 1 A). Coxae green with lobes brown; trochanters green; fore and middle femora green; hind femora basal half green, apical half brown, knees brown; femora with ventral spines brown at base and black apically; tibiae brown, with spines brown; tarsi brown. Abdominal apex green, cerci green with apex brown, subgenital plate light blue green. Ovipositor rather pale brown with tint of green in some specimens, dorsal and ventral margins and apex darker brown.

Measurements (2 males, 2 females). Body: male 11.7–14.7, female 15.9–16.8; pronotum: male 6.1–6.2, female 5.5; tegmen: male 6.2–7.1, female 6.8–7.2; hind femur: male 19.1–19.9, female 21.1–21.6; ovipositor: female 8.0– 8.4; ovipositor height: female 3.7–4.9 mm.

Etymology. This species is named after the type locality, Singapore in Malay; noun in apposition.

Remark. The new species described was already collected by Prof. D. H. Murphy during his Orthopteran research in Singapore from the 1960s to 1980s, though this species remained unidentified to date.
