Five new species of Bradina Lederer (Lepidoptera, Crambidae) from China, with remarks on the morphology of the genus
Bradina is a species-rich genus that differs from most other Spilomelinae genera because of its distinctive wing venation. Most species of this genus are very similar in appearance. In this study, we have studied morphological characteristics of the genus and eight closely related species from China. Among them, B. falciculata Guo & Du, sp. nov., B. fusoidea Guo & Du, sp. nov., B. spirella Guo & Du, sp. nov., B. ternifolia Guo & Du, sp. nov. and B. torsiva Guo & Du, sp. nov. are described as new to science. Bradina megesalis (Walker, 1859), B. translinealis Hampson, 1896 and B. subpurpurescens (Warren, 1896) are redescribed based on their holotypes and additional material, and the latter two are newly recorded from China and their genitalia are described for the first time. The images of the habitus and genitalia of these eight species are provided, with a key to their identification.
