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.
