What the sources say about this taxon, as written.
behaviour · bio.acousti.ca
The call of O. incisus consists of short, 0.5–0.9 s trains of syllables produced at the rate of 20–30 syllables/sec; (at 22°C); mean syllable duration is 0.01954 (SD=0.00200, n=84), with the frequency peak at 14.6–22.6 kHz (Figs. 49A–C). The call, produced by the males only at night, is soft and barely audible to the human ear.

Differential diagnosis. Similar to O. abreuae in its general appearance but different in the morphology of the male 10 th tergite, cerci, titillator, and subgenital plate ( Figs. 17 A–I), the female 10 th tergite and subgenital plate ( Fig. 16B ), and bioacoustic characteristics ( Figs. 49 A–C). This species also appears to have only a green color morph. General. General characteristics as in the description of the genus. Stridulatory file. Stridulatory file 2.2 mm long, 0.12 mm wide, with 82 teeth ( Fig. 17J ). Abdomen. Male 10th tergite with two narrow posterior lobes separated by nearly rectangular incision wider than single lobe ( Fig. 17A ); female 10th tergite with deep emargination reaching almost to base of tergite. Cercus short, strongly flattened dorso-ventrally, less than twice as long as wide, bent downwards when seen from side; with basal inner tooth distinctly narrowed towards its apex and with subapical tooth large, blunt, and distinctly separate from apex of cercus ( Figs. 17E, F ). Phallus with well developed, strongly sclerotized, unpaired titillator; with small basal plate, evenly narrow stem, and small apical part as seen from above; apical third of titillator strongly flattened laterally ( Figs. 17G, H ). Subgenital plate with posterior part strongly elongated, diverging into two narrow, incurved lobes and with narrow, spine-like process between them, about as long as third of lobe ( Fig. 17B ); dorsal part of subgenital plate with two small, vertical protrusions at base of apical lobes ( Fig. 17I ); styli minute and stub-like, about as long as wide. Female subgenital plate with posterior emargination wide and shallow, about as wide as posterior lateral lobes ( Fig. 16B ). Coloration. Coloration light green; head yellow to green, occiput dark, almost black; pronotum green with distinct dark dots in metazona; legs green except for yellow tarsi; ovipositor dark brown, apex almost black. ( Figs. 16 C–E). Bioacoustics. The call of O. incisus consists of short, 0.5– 0.9 s trains of syllables produced at the rate of 20–30 syllables/sec; (at 22°C); mean syllable duration is 0.01954 (SD=0.00200, n=84), with the frequency peak at 14.6–22.6 kHz ( Figs. 49 A–C). The call, produced by the males only at night, is soft and barely audible to the human ear.
