Phylogenetic relationships of 13 genera of Schoenobiinae (Lepidoptera: Crambidae) are postulated based on traditional characters of genitalia and wing venation and new characters of the descaled whole body. The phylogenetic analysis yielded one most-parsimonius tree (length 287 steps, CI= .36, RI= .62) that resulted in a monophyletic clade of all genera of Schoenobiinae examined. The monophyly of the Schoenobiinae is supported by a Bremer support value of five. Donacaula is not congeneric with the type-species of Schoenobius, S. gigantellus. The analysis confirms Lewvanich‘s hypothesis that Scirpophaga, Donacaula, Schoenobius, Catagela, and Helonastes are closely related. Based on this analysis, the New World genera appear to have originated in the Neotropical region with four independent dispersals to the Nearctic Region.
The revision of Donacala resulted in recognition of 20 species that were previously described and descriptions of ten new species. Neotypes were designated for D. sordidella, D. unipunctella, D. tripunctella, D. dispersella, D. aquilella. Lectoypes were designated for D. albicostella, D. pallulella, D. immanis, D. pulverealis. Donacaula bicolorella was synonymized with D. roscidella, D. uniformella with D. albicostella, D. lanceolella with D. immanis, and D. amblyptepennis with D. longirostrella. Adults, wing venation, and genitalia of New World species of Donacaula are illustrated for the first time, and new distributional records are reported. A key to species, diagnoses, and photographs of imagoes and male and female genitalia are provided.
