Figs. 3 View FIGURE 3 A–E, 102I

Material examined. Indonesia: East Java, Tretes, Gunung Arjuna (7°42'S, 112°36'E), 800–1100, in hollow stems, 25.iii.1995, leg. S. Ingrisch— 1 male (Bonn ZFMK) GoogleMaps ; West Java, Sukabumi— 1 female (Paris MNHN) .

Description. Small species. Head: Face oval; forehead nearly smooth with very fine impressed dots; fastigium verticis about twice as wide as scapus; ocelli little distinct; fastigium frontis separated from fastigium verticis by a very fine suture; subocular furrows shallow. Abdominal tergites two and three each with 2 rows of stridulatory teeth.

Wings about covering abdomen ( Fig. 3A View FIGURE 3 ). Tegmen: Media anterior fused in basal area with radius, after both divided, radius gives rise to radius sector; media posterior absent; cubitus anterior forks between basal third and mid-length into two veins, CuA1 and CuA2; cubitus posterior undivided, free throughout; with 4 anal veins.

Legs: Fore coxa with a large spine at fore margin; fore and mid femora unarmed; fore and mid tibiae with four pairs of large ventral spines and one pair of smaller ventral spurs; hind femur with 7–8 external and 3–4 internal spines on ventral margins; hind tibia with spaced spines on both dorsal margins, ventral margins with one preapical spine; with 3 apical spurs on both sides.

Coloration. General color light with dark marks; vertex yellowish brown, fastigium blackish; pronotum dark red brown with yellowish lateral and apical areas but rim dark; posterior abdominal tergites dark red brown, anterior tergites and sternites light brown, legs yellowish with dark brown genicular areas. Face black in middle, genae and mouth parts dark brown, fastigium verticis and fastigium frontis, ventral margin of clypeus and maxillary palpi yellowish ( Fig. 3B View FIGURE 3 ). Tegmen semi-transparent yellowish with brown veins; hind wing semitransparent white with yellow veins and brown cross-veins, the cross-veins adorned by narrow light brown bands.

Male. Eighth abdominal tergite moderately prolonged behind. Ninth abdominal tergite moderately prolonged behind with converging and strongly down-bent lateral margins; furrowed in midline, towards tip with a pair of large, strong, elongate swellings that carry on ventral tip a swollen subacute tooth ( Fig. 3C View FIGURE 3 ). Tenth abdominal tergite largely reduced. Subgenital plate wider than long with lateral margins in circa basal half subparallel, afterwards narrowing, faintly concave, apical area bilobate with obtuse angular excision; apical area little depressed with a small deeper groove in middle and another small groove at base; styli rather short and stout, inserted at lateral angles of approaching part of margins.

Female. Subgenital plate with converging lateral margins, tip sub-truncate. Ovipositor upcurved in basal half, with apical widening.

Measurements (1 male).—body w/o wings: 19; pronotum: 3.2; tegmen: 11.5; hind femur: 7.5; antenna: 70 mm.
