Material examined. Holotype (female): Indonesia: Java, West Java, Cibodas [Tjibodas], elev. 1400–1500 m (6°43'S, 107°0'E), 31.iii.–1.iv.1995, leg. S. Ingrisch—(Bonn ZFMK). GoogleMaps

Diagnosis. The new species differs from all other species of the genus, for which this characters is known, by the pair of very short posterior projections of the female seventh abdominal sternite ( Fig. 41K View FIGURE 41 ).

Description. Small to medium sized species. Head: Face not particularly large; in frontal view roughly oval; forehead nearly smooth; fastigium verticis distinctly wider than scapus; median and lateral ocelli small, little distinct ( Fig. 40H View FIGURE 40 ). Abdominal tergites two and three each with two rows of stridulatory pegs (4, 12; 15, 18; n = 1 female; Fig. 40I View FIGURE 40 ).

Wings little surpassing apex of abdomen ( Fig. 40G View FIGURE 40 ). Tegmen widest in basal quarter: Radius with two branches, both forked near tip; media anterior free from base, undivided; cubitus anterior forks into two veins near end of basal third; cubitus posterior undivided, free throughout; with 3 anal veins and an incomplete fourth vein.

Legs: Fore coxa with small spine at fore margin; fore and mid femora unarmed; fore and mid tibiae with 4 pairs of rather short ventral spines and 1 pair of smaller ventral spurs [the first pair very short; left mid leg missing]; hind femur with 7 external and 8–9 internal spines on ventral margins, little increasing in size towards posterior end; hind tibia with spaced, comparatively short spines on both dorsal margins, ventral margins with one pre-apical spine each; with 3 apical spurs on both sides.

Coloration. General color uniformly medium brown, underside lighter; flagellum of antennae dark brown ( Fig. 102F View FIGURE 102 ). Face yellowish brown, compound eyes dark brown, mandibles reddish brown, palpi yellowish. Tegmen semitransparent yellowish, veins yellowish; hind wing transparent with yellowish veins.

Male unknown.

Female. Seventh abdominal sternite rather unmodified, apical margin with a pair of very short convex projections. Subgenital plate roughly semi-circular, membranous at base ( Figs. 41 View FIGURE 41 J–K). Base of ovipositor with two small sclerites on both sides of very base. Ovipositor elongate, strongly curved behind base, afterwards slightly curved dorsad; longer than hind femur; tip obtuse ( Fig. 41I View FIGURE 41 ).

Measurements (1 female).—body w/wings: 26; body w/o wings: 23; pronotum: 3; tegmen: 19; tegmen width: 5; hind femur: 10; ovipositor: 12 mm.

Etymology. The new species is named for the short posterior projections of the female seventh abdominal sternite; from Latin brevis (short).
