Taxonomic study of Targalla delatrix (Guenee) and its close relatives from East and Southeast Asia with description of a new species (Lepidoptera: Euteliidae)

摘要

Targalla delatrix (Guenee) and its close relatives from East and Southeast Asia are revised. A new species, T. silvicola sp. nov. is described from China, Vietnam, Laos, Taiwan and Japan. T. subocellata pantarcha Turner is recognized here as a good species distinct from T. subocellata (Walker) and is treated as T. pantarcha (Turner) stat. rev. Additionally, T. infida Walker sp. rev. is treated here as a distinct species from T. palliatrix (Guenee). In addition, using the DNA barcoding data of mitochondrial DNA (COI) genes, together with the Targalla data already registered in Gen Bank, we can distinguish seven Targalla species successfully and an NJ-tree is given.
