Taxonomy of Baetis Leach in Israel (Ephemeroptera, Baetidae)

Collection: Pensoft Publishers

Keywords: Aquatic insects · Topics: Freshwater macroinvertebrate diversity and ecology, Aquatic Invertebrate Ecology and Behavior, Fish Ecology and Management Studies

The taxonomy and systematics of the genus Baetis Leach (Ephemeroptera: Baetidae) in Israel is clarified for the first time as part of an ongoing comprehensive survey of the Israeli mayfly fauna. Six clearly defined species are currently recognized in Israel, four of which are described here as new to science. The validity of all species is supported by a molecular analysis of the mitochondrial COI gene. A key for the identification of the Israeli species based on the nymphal stage is provided, as well as data on their distribution patterns and ecology. The local fauna represents four Palearctic species groups, three of which reach their limit of distribution range in Israel. Baetis species typically inhabit lotic, pristine habitats in northern Israel, with few exceptions for some species that can be found in the Dead Sea area or in ephemeral ponds.
