Figs. 47 A–B, 48G, 50A–B, 51J–K, 100D

Material examined. Thailand: Prachinburi, Khao Khieo , elev. 1300 m (14°15'N, 101°35'E), 17.x.1990, leg. S. Ingrisch— 1 female, 1 male (Bonn ZFMK) .

Diagnosis. The general habitus of this species is similar to other species of the genus that have yellowish tegmina without black marks. Diagnostic are in male the projections of the ninth abdominal tergite that are rather stout and suddenly terminating into the little curved apical spine. The females have the subgenital plate in somewhat less than basal half with nearly subparallel margins and at very base a distinct transverse groove with black bottom and a narrow membranous structure in middle; the apical half of the subgenital plate has nearly straight converging margins terminating into a slightly bilobate tip. The female is described here for the first time.

Description. Medium sized to large species. Head: Face ovoid; forehead nearly smooth with some scattered impressed dots and very fine transverse riffles, in female more riffles than in male; fastigium verticis wider than scapus; ocelli distinct, yellowish brown; fastigium frontis separated from fastigium verticis by a very fine suture; subocular furrows shallow ( Fig. 48G ).

Wings surpassing hind knees and reaching about middle of stretched hind tibia ( Fig. 47 A–B). Venation of tegmen irregular in and different between both specimens at hand: Male: Radius with a single free vein, which after basal third sends an oblique cross-vein to and fuses with media anterior, the fused vein forks near tip of tegmen. Media anterior free from base but touches radius in subbasal area in a single point, after it received the oblique cross-vein from R, it sends an oblique cross-vein to CuA, which immediately divides into MP and CuA.—Female: Radius with two branches, both forked near tip; media anterior free from base. Cubitus anterior at base with a single branch that forks into two veins, the anterior branch makes a curvature and then fuses with MA but immediately they divide again, after separation MP+CuA1 then fuses another time with CuA2, but they separate immediately. In both specimens: Cubitus posterior undivided, free throughout; with 4 anal veins.

Legs: Fore coxa with a 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 about 7–11 external and 12–20 internal spines on ventral margins; hind tibia with spaced spines on both dorsal margins, ventral margins with one pre-apical spine and with 3 apical spurs on both sides.

Coloration. General color brown; head and pronotum black with a brown band along hind margin of pronotum and with or without brown posterior area of vertex ( Fig. 100D ). Face black; clypeus with yellow margin and short line in middle; compound eyes red brown; maxillary palpi dark brown. Tegmen semi-transparent yellowish, veins light brown, cross-veins dark brown to black; hind wing semi-transparent ochre, main veins light or medium brown, cross veins dark brown or black adorned on both sides by dark or medium brown bands.

Male. Eighth abdominal tergite prolonged. Ninth abdominal tergite with oblique vertical surface; furrowed in midline; baso-medial area flat, afterwards on both sides with a stout oblique swelling carrying at ventro-medial angle a strong cylindrical process, little curved towards tip and terminating into a compressed acute tip ( Figs. 50 A– B). Paraproctes forming extended plates from base of cerci. Subgenital plate wider than long with a medial furrow (probably soft, distorted in specimen); apical margin wide roundly excised in middle; styli stout, upcurved, inserted at apical margin nearly in middle between lateral margin and medial furrow. Phallus membranous.

Female. Seventh abdominal sternite of rather normal shape, at end slightly overlapping with membranous basal area of subgenital plate. Subgenital plate in little less than basal half with subparallel lateral margins and surface membranous, afterwards with converging margins and surface sclerotised with a faint medial furrow, apex slightly bilobate; at very base with a pit edged on both sides by strongly sclerotised black margins ( Fig. 51J ). Base of ovipositor normal. Ovipositor elongate, straight; tip subobtuse ( Fig. 51K ).

Measurements (1 male, 1 female).—body w/wings: male 43, female 42; body w/o wings: male 37, female 30; pronotum: male 6.8, female 5.8; tegmen: male 31, female 29; tegmen width: male 11.5, female 10.5; hind femur: male 19, female 19; antenna: male 100, female 115; ovipositor: female 25 mm.
