Description. Body small and slender ( Fig. 21a, b View FIGURE 21 ). Head with fastigium of vertex narrowly conical, middle furrow distinct. Length of apical segment of maxillary palpi equal or slight longer than subapical one, with slightly widened apex.

Pronotum disc narrow and long, covering base of tegminal mirror, transverse sulcus indistinct, with a yellowish median stripe, dorsal disc roundly turned into lateral plate, with indistinct humeral sinus. Fore leg with coxal spur relatively short. Tegmina and wings long. Hind tibia with 3 pairs of apical spurs.

Male 10 th tergite with posteriomedian notch quite deep. Epiproct elongate lobe with a posteriomedian notch, directed backward ( Fig. 21 View FIGURE 21 c–e). Male cerci club-shaped with trident apex, upper lobe much longer than lower bifurcated branch ( Fig. 21e, f View FIGURE 21 ). Subanal plate with 2 broad lobes tapering toward apex ( Fig. 21f View FIGURE 21 ), fused with subgenital plate. Subgenital plate short and broad with round lateral terminal, small posteriomedian notch, styli comparatively long and close to each other ( Fig. 21f View FIGURE 21 ). Male genitalia not dissected.

Female subgenital plate broad and short with a small posteriormedian notch and a distinct transverse fold. Ovipositor moderate long, nearly straight with acute apex ( Fig. 21b View FIGURE 21 ).

Measurements (mm). Body: ♂ 8.1, ♀ 9.9–11.0; Pronotum: ♂ 3.5, ♀ 3.2–3.4; Tegmina: ♂ 9.0, ♀ 14.3–15.1; Hind femora: ♂ 9.5, ♀ 10.0–10.2; Ovipositor: 7.5–7.9.

Comparison. This species close to Pseudoteratura (Pseudoteratura) raggei (Bey-Bienko, 1971) (new male described in this paper, see bellow) from Sarawak, Borneo, but male epiproct, cerci, subgenital plate, subanal plate and female subgenital plate are all different from in details as showed in figures.

Etymology. Species name refers to male cerci in trident shape.
