Marasmia trapezalis

This taxon used to be in Cnaphalocrocis, but has been transferred to Marasmia recently. This is reflected in the GlobizPyraloidea website. Referencing from that site,

trapezalis (Guenée, 1854), as Salbia; TL Sierra Leone
= Botys convectalis Walker, 1865; TL South Hindostan
= Botys suspicalis Walker, 1859; TL Ceylon
= Dolichosticha perinephes Meyrick, 1886; TL Fiji
