Material examined. 1 male, 3 females. Peninsular Malaysia, Selangor: 1 female, coll. H. N. Ridley; 1 female, Kuala Lumpur, coll. N. C. E. Miller, 1–30 November 1938; 1 female, 1 male, Kuala Lumpur, Guillemard Road, coll. H. T. Padgen, 1 October 1952, 14 July 1954 (all BMNH).
Discussion. The species was so far only known from the female holotype. In BMNH, SI found beside of three females and one male, which gives the opportunity to describe the male characters for the first time.
Description (male). Habitus as shown in Fig. 3 A. Fastigium verticis with apex truncate. Frons smooth to slightly punctuated (Fig. 3 B). Pronotum with transverse sulcus little distinct; posterior margin truncate. Tegmen only little surpassing abdomen (in females reaching middle or apex of ovipositor). Prosternal spines long. Mesosternal lobes angular, subflat; metasternal lobes subflat, terminating into a small tubercle. Femora with the following number of spines on ventral margins: profemur 0 external, 1 internal; mesofemur 4-5 external; postfemur 7-8 external, 6 internal. Knee lobes of profemur obtuse on external, short-spinose on internal side, of mesofemur obtuse on external, spinose on internal side.
Male. Stridulatory vein on underside of left tegmen faintly sinuate, 2.1 mm long, with 165 teeth; teeth in apical area very dense (Fig. 3 C). Tenth abdominal tergite at apical margin with wide concave (obtuse triangular) excision. Epiproct triangularly rounded; with dorsal furrow. Paraprocts ‘normal’. Cerci short conical with large curved basointernal process reaching nearly to tip of cercus (Fig. 3 D). Subgenital plate with lateral margins roundly curved up in a larger than 90° angle; at distal end with a small tubercle; apical margin roundly excised and styli inserting on internal margin of excision (Fig. 3 E). Styli dorso-ventrally compressed with dorsal surface slightly convex, ventral surface concave; at base with a large obtuse ventral projection; inner and apical margins provided with a row of acute teeth (Figs. 3 E–F). Titillators largely reduced: there is a faint darkening of what might be the relics of the apex of the probably fused titillators and a pair of distinct fusiform baso-lateral sclerites (Figs. 3 G–H).
Colouration. Yellow brown; could be green when alive. Head green; antennae and mouthparts yellow. Tegmen with a white “callus spot behind stridulatory area.
Measurements (1 male, 1 female). BL: male 20.0, female 22.0; BWL: male 23.0, female 27.0; PL: male 6.3, female 6.3; TL: male 15.5, female 19.0; HFL: male 16.5, female 18.5; OL: female 11.0 mm.
