Diagnosis. On wing pattern, O. vatama is close to the yellow and brown form of O. obtusa , having a hooked and strong forewing apex. The apex is broader and truncate in O. vatama but blunt and slightly tapering in O. obtusa . The forewing outer margin is more protruding in O. vatama . The postmedial fascia on the forewing is more arcuate in O. vatama , a characteristic shared with O. speciosa . O. vatama has a much broader and more distinctly margined central band on the hind wing than O. obtusa and O. speciosa , but lacks the brown patch below the apical patch which is present in those two species. In the male genitalia, O. vatama is distinctive in the conspicuously bilobed saccus (indistinct in Fig. 53 View FIGURES 33 – 53 ). Other structures are close to those of O. andrema , but the uncus is oval and narrowly excavated medially, while it is flat or shallowly concave on the posterior margin in O. andrema ; the gnathos is a long narrow process, but broad and triangular in O. andrema ; the valva is broad and short, rounded or truncate distally, bearing one broad, hairy, costal basal process and a narrow to broadly triangular, or pointed ventral process, whereas in O. andrema , the former process is shorter and pointed, and the ventral process is absent; the aedeagus of O. vatama is decorated with many small spines, a small pointed anterior process, and a distinct spinose cornutus, whereas in O. obtusa , it bears a strongly sclerotized, nearly ring-like sclerite, and a smaller and indistinct cornutus. The female genitalia have a small, round corpus bursae, and a developed ductus bursae.
