Calamotropha Zeller, 1863: 8 .

Type species: Tinea paludella Zeller, 1824 .

Aurelianus Bleszynski, 1962: 2 .

Type species: Chilo discellus Walker, 1863 .

Myeza Walker, 1863: 190 .

Type species: Myeza tonsalis Walker, 1863 .

Diagnosis. Calamotropha is characterized in the male genitalia by the uncus with setae at base. It is similar to Pseudocatharylla Bleszynski, 1961 in appearance, and it can be distinguished in the male genitalia by the symmetrical valvae, and the costa without process at the base. In Pseudocatharylla, the valvae are asymmetrical in most species, and the costa has a process at the base.

Distribution. This genus is widely distributed in the Palearctic, Oriental, Ethiopian and Australian regions.
