Diagnosis. The genus is distinguishable from other genera by the forewing having the fascia absent or only an oblique line present from apex to inner margin. It is different from Schoenobius by the juxta of male plate-like and the apex not elongated, and from Niphadoses by the valva not constricted apically. More information can be seen in the discussion under the genera closely related to Scirpophaga .

Distribution. Oriental, Palaearctic, Australian and African Regions.

Remarks. The genus has about 40 species reported. Lewvanich (1981a) revised the genus from the Old World. Chen et al. (2006b) revised the Chinese species, in which 20 species were reported from China. The differences among the species groups and allied genera see Table 1 View Table 1 and 2 View Table 2 (Discussion part)
