Platyphora Gistel, 1857 from Itatiaia National Park, southeastern Brazil: new synonymy and new records (Insecta, Coleoptera, Chrysomelidae)

Abstract Platyphora Gistel, 1857 is the largest genus in Chrysomelinae with about 450 species of which 181 occur in Brazil. The Itatiaia National Park is one of the most important Conservation Units of the Atlantic Rainforest and 36 Platyphora species are recorded from the park. We have recorded 38 species of Platyphora. The synonymy of Platyphora fraterna (Stål, 1857) and Platyphora fasciatomaculata (Stål, 1857) is proposed. Platyphora bilimbata (Stål, 1857), P. carolina (Stål, 1858) and P. semiviridis (Jacoby, 1903) are new records for the park; additional distributional records are provided for 18 species. Of the 38 species, 24 are illustrated for the first time.摘要：扁角叶甲属（Platyphora Gistel, 1857）是叶甲亚科（Chrysomelinae）中最大的属，共包含约450个物种，其中181种分布于巴西境内。伊塔蒂亚亚国家公园（Itatiaia National Park）是大西洋雨林最重要的保护单元之一，此前该公园共记录到扁角叶甲属物种36种。本研究共记录该属38个物种，提出将Platyphora fraterna (Stål, 1857)与Platyphora fasciatomaculata (Stål, 1857)处理为异名；Platyphora bilimbata (Stål, 1857)、P. carolina (Stål, 1858)及P. semiviridis (Jacoby, 1903)为该公园的新分布记录；另有18个物种补充了其分布记录。在本次记录的38个物种中，24个物种为首次附特征图版。
