Baetidae (Baetidae, Ephemeroptera) in the Maghreb: state of the art, key, and perspectives.

Among mayflies, Baetidae are often considered as easy to recognise at the family level, but difficult to identify at lower level. In several faunistic or ecological studies, the identification remains at the family level; Baetidae are generally considered as widespread and ubiquitous, therefore as poorly informative for ecological studies or bioassessments. Here, a straightforward identification key is offered to larvae of the ten genera of Baetidae reported from Maghreb based on easily observable and understandable characters. The diversity, ecology, and distribution of each taxonomic unit (genera or subgenera) are discussed and the main difficulties for deeper identification are pointed out. Future challenges and remaining taxonomic riddles for Maghrebian Baetidae are detailed.

An unexpected new species of Habrophlebia from Algeria (Ephemeroptera, Leptophlebiidae).

We describe a new species of Habrophlebia, H. djurdjurensis sp. nov., based on nymphal, imaginal, and egg stages obtained by sampling from the Great Kabylia watershed, north-central Algeria. The new species was previously identified as H. cf. fusca by Lounaci et al. 2000. Habrophlebia djurdjurensis is in fact more related to H. vaillantorum Thomas, 1996 but can be separated by characters on the nymphs and male imago. This is the fourth species of Habrophlebia reported from North Africa.
