Revision of the Australian species of Hyalobathra Meyrick (Lepidoptera : Pyraloidea : Crambidae : Pyraustinae) based on adult morphology and with description of a new species

摘要

The genus Hyalobathra Meyrick is redefined based on five Australian species including the type species. The four named Australian species, H. archeleuca Meyrick, H. unicolor (Warren), H. miniosalis (Guenee) and H. minialis (Warren), are redescribed and a new species, H. crenulata sp. n., is described. Hyalobathra unicolor is removed from synonymy with H. illectalis (Walker), and lectotypes are designated for H. archeleuca, H. minialis and for H. rhodoplecta Turner, a synonym of H. miniosalis. The presence of H. paupellalis (Lederer) in Australia could not be confirmed, but its genitalia are figured. Two previously included species, 'Hyalobathra' aequalis (Lederer) and 'H.' brevialis (Walker), are excluded from Hyalobathra, as they lack its generic apomorphies, but cannot at present be assigned to any other genus.
