Diagnosis. The new species is similar to O. auriculata in general habitus and wing venation. The apical projections of the male ninth abdominal tergite are also compressed and slightly sinuate as in that species, but they are shorter, relatively wider in middle and with less prolonged acute tip ( Figs. 25 View FIGURE 25 N–O). The male subgenital plate is wider and shorter in O. bamusbama than in O. auriculata and the apical margin is widely concave, only the angles with the bases of the styli projecting while in O. auriculata it is angularly excised with rounded bottom. The styli are straight and distinctly conical while in O. auriculata they are curved and hardly narrowing towards tip. The projections of the male ninth abdominal tergite are compressed and slightly sinuate as in O. auriculata , but shorter and wider and sit on a swollen socket, the tip is rounded not acutely projecting as in the latter.
Description. Small species. Head: Face ovoid; forehead nearly smooth with scattered impressed dots and very fine riffles; fastigium verticis about as wide as scapus, separated by a suture from fastigium frontis; ocelli distinct, lateral ocelli elongate; subocular furrows present ( Fig. 25L View FIGURE 25 ). Abdominal tergites two and three with stridulatory pegs.
Wings covering about abdomen ( Fig. 25K View FIGURE 25 ). Tegmen: Radius with radius sector branching in about mid-length of tegmen; only RS branching near tip; media fused with radius in about basal quarter, than free and unbranched; media posterior absent; cubitus anterior and cubitus posterior both single branched, free throughout; with 4 anal veins.
Legs: Fore coxa with 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 9–10 external and 9 internal spines on ventral margins; hind tibia with spaced spines on both dorsal margins, ventral margins with one pre-apical spine; with 3 apical spurs on both sides.
Coloration. General color light brown; pronotum with some indistinct pattern; legs with dark strokes. Face yellowish brown to medium brown; a pair of ovoid marks at base of fastigium verticis, ventral surface of scapus, and apical half of mandibles dark blackish brown. Tegmen yellowish semi-transparent; hind wing semitransparent, veins yellow.
Male. Eighth abdominal tergite prolonged and down-curved at end ( Fig. 25M View FIGURE 25 ). Ninth abdominal tergite with posterior area strongly bent down, deeply furrowed in midline, at ventral margin on each side of furrow with a little globular, setose swelling that carries at tip a compressed, up-bent process with swollen base and subacute tip ( Figs. 25 View FIGURE 25 N–O). Epiproct small, triangular. Subgenital plate rather short with convex lateral margins and concave apical margin; styli inserted at projecting lateral angles of apical margin, rather long and straight, almost longer than length of subgenital plate; conically narrowing towards tip.
Female unknown.
Measurements (1 male).—body w/wings: 23; body w/o wings: 20; pronotum: 4.7; tegmen: 17; tegmen width: 5.5; hind femur: 12 mm.
Etymology. The new species is named after the type locality; noun in apposition.
