Diagnosis. Adult (Fig. 20) wingspan 15.5–17.0 mm. Calamotropha okanoi is similar to C. formosella Bleszynski, 1961 in the forewing pattern. It can be distinguished by the forewing with the subterminal fascia excurved nearly by a right angle at anterior 1/3; in the male genitalia by the valva with a short triangular dorsoapical process and an ill-produced ventroapical process obtuse apically formed by the apex shallowly concave, and the vesica with a row of spiniform cornuti (Fig. 42). In C. formosella, the subterminal fascia is arched outward at above middle (Fig. 12); the valva has a stout thumb-shaped dorsoapical process and a shorter triangular ventroapical process formed by the apex deeply concave in C shape, and the vesica has a strong spine-like cornutus (Li & Li 2012: Fig. 4A). The female genitalia of C. okanoi are characterized by the heavily sclerotized spinous antrum with a posterior lobe at each side laterally (Fig. 62)
