B29FAAC6BC1B5DAE888B90C8B1C33E29.taxon	diagnosis	Diagnosis, adult (Figs 1, 2, 4). The new species closely resembles Donacia bicolora Zschach, but can be distinguished by the following diagnostic characteristics: the rows of punctures are still clearly visible even in the last third of the elytra (D. bicolora: these punctures are almost completely obscured by the silky, shiny, fine wrinkles in the last third of the elytra).; and it generally occurs in two distinct color morphs: cupreous and greenish (D. bicolora exhibits a variety of body colorations, commonly greenish, bluish, or blackish). The legs are entirely metallic.	en	Kim, Joong Youb, Han, Yeong-Deok, Lee, Jong Eun (2025): A new species of the genus Donacia Fabricius (Coleoptera, Chrysomelidae, Donaciinae) from South Korea: morphology, ecology, and COI gene analysis.
