Figs. 35 K–N

Material examined. Philippines: Luzon, leg. Jagor— 1 female, 1 male (Berlin ZMB) .

Description. Small but rather stout species. Head: Face ovoid; fastigium verticis little wider than scapus; ocelli visible but little distinct; fastigium frontis not clearly separated from fastigium verticis; subocular furrows present but not strong. Wings about covering abdomen ( Fig. 35N ). Tegmen: Radius with two branches, both forked near tip; media anterior free from base; forked behind basal third in two steps into three veins: MA, MP1, MP2; cubitus anterior and cubitus posterior both single branched, free throughout; with 3–4 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 6–8 external and 4–14 internal spines on ventral margins; ventral margins with one pre-apical spine; with 3 apical spurs on both sides.

Coloration. General color uniformly yellowish brown. Face uniformly yellowish brown; hind tibia dark brown or black, except at base and apical area. Tegmen semitransparent with darker venation, yellowish near base and centre, blackish towards rims; hind wing semitransparent with darker venation.

Male. Eighth abdominal tergite of normal length. Ninth abdominal tergite globular, faintly furrowed in midline and before apex with a faint swelling on both sides of that furrow, terminating at apical margin into a pair of short blunt spines ( Fig. 35K ). Subgenital plate rather short, wider than long; apical margin convex on both sides, concave in middle; styli short.

Female. Seventh abdominal sternite wider than long, unmodified. Subgenital plate grooved on both sides of midline; apical margin in middle projecting (up-bent and curled in holotype) with truncate tip in middle, laterally concave on both sides ( Fig. 35L ). Base of ovipositor with small conical projection on both sides. Ovipositor long, moderately upcurved throughout; tip subacute ( Fig. 35M ).

Measurements from Gerstaecker (1860) (1 female).—body w/o wings: female 25; tegmen: female 18; ovipositor: female 13.5 mm.
