Male genitalia (Fig. 12). Tegumen broadly oval, sclerotized laterally. Costa as long as tegumen, slightly broadened at base, rounded at apex, with long dense setae ventrally, distal 4/5 nearly parallel dorso-ventrally; dorsal margin straight; ventral margin with lobed process obliquely outward. Sacculus elongate oval, about 3/4 length of costa, acute distally. Transtilla broad at base, narrowed triangularly, curved ventrad distally, acute apically.
