Diagnosis. The new species is characterised by the long male cerci with obviously sub-membranous apical area and with an internal projection near end of basal third that carries at end two minute spines. Characteristic are also the titillators that have the sclerotised area small and only weakly expressed and embedded into a pair of rather large membranous structures with widened central areas that carry near end large hairs; apical areas narrow and approached to each other.
Description. Medium sized. Tegmina surpassing middle of hind tibia. Femora with the following number of spines on ventral margins: fore femur 2–6 external, 4–6 internal; mid femur 5–7 external, 3–4 internal near base; hind femur 10–11 external, 7–11 internal.
Male. Stridulatory file with about 95 teeth. Tenth abdominal tergite terminating into two short obtuse lobes, concave or obtuse-angularly excised in between. Epiproct with converging lateral margins except in apical area; apex truncate; dorsal surface with a deep pit. Paraprocts with compressed, roughly triangular projections from internal margin. Cerci faintly sinuate, with a little compressed internal tooth before middle of length with slightly concave anterior and convex posterior margins, at rounded tip with a pair of minute and little curved spines; apical areas of cerci collapsed in preserved specimens, might be partly membranous, apex obtuse. Subgenital plate roundly excised at apex; styli of almost equal length with excised area. Titillators mostly hyaline, simple; in middle with an obtuse projection that forms the base of a large, compressed, hyaline bursa of oval-triangular shape, surpassing titillators and with a tubular projection at inner apical angle; inner surfaces of bursae about one quarter before apical margin provided with a row of long bristles, the longest bristles reaching the tip of the tubular projection.
Female. Unknown.
Coloration. Yellowish brown with patterns 1, 2, 3, 4 or with all patterns (0 to 4) and vertex with a black medial band and legs with little distinct maculation.
Measurements of male.—body: 19; pronotum: 5.0–5.2; tegmen: 27–28; hind femur: 14.5–15.0 mm.
Etymology: The new species is named for the soft apical area of the male cerci.
