Leptophlebiidae (Insecta: Ephemeroptera) from state of Bahia, Brazil

Abstract Leptophlebiidae is the family with the most diversity of species and wide distribution in the Southern Hemisphere. There are 95 species of Leptophlebiidae recorded in Brazil, but for the state of Bahia there are only 21 species. A check list and new records of Leptophlebiidae (Ephemeroptera) are presented to the State of Bahia. A total of 16 genera and 40 species of Leptophlebiidae were identified on this study. The species Fittkaulus cururuensis, Hylister obliquus, Miroculis (atroari) duckensis and Miroculis (Ommaethus) froehlichi are reported for the first time to the State of Bahia, increasing the number of Leptophlebiidae species from 21 to 25. Now, the Bahia is one of the states with the largest number of Leptophlebiidae species records, behind only of the state of Espírito Santo which has 26 species of this family.

摘要：细蜉科（Leptophlebiidae）是南半球物种多样性最为丰富、分布范围最广的蜉蝣类群。巴西境内已记录细蜉科物种共计95种，但巴伊亚州（Bahia）仅记载有21种。本研究针对巴伊亚州的细蜉科（蜉蝣目，Ephemeroptera）类群整理并发布了一份物种名录及新分布记录，共鉴定出该科昆虫16属40种。其中Fittkaulus cururuensis、Hylister obliquus、Miroculis (atroari) duckensis及Miroculis (Ommaethus) froehlichi为巴伊亚州首次记录的细蜉科物种，使该州已记录的细蜉科物种总数从21种增至25种。目前，巴伊亚州的细蜉科物种记录数在巴西各州中位居前列，仅次于记录有26种该科物种的圣埃斯皮里图州（Espírito Santo）。
