North African Endemism: A New Species of Black Fly (Diptera: Simuliidae) from the Djurdjura Mountains of Algeria.

Discoveries of endemic species highlight areas of biogeographic and conservation interest. Endemic species, however, are often morphologically disguised as more common and widespread species. The larval polytene chromosomes revealed a new species of black fly, Prosimulium fungiforme, from the Djurdjura Mountains of northern Algeria, and its female, male, pupa, and larva are described. The species is chromosomally unique; none of its 11 chromosomal rearrangements are shared with other species. Although the new species structurally resembles Prosimulium rufipes (Meigen) with which it previously has been confused, it can be distinguished from all other known species of Prosimulium in the Western Palearctic based on at least one character in each described life stage. Symbiotic organisms included two species of microsporidia, at least one of which is probably undescribed, one unknown protozoan pathogen novel in simuliids, and the trichomycete fungus Harpella melusinae Léger and Duboscq. Associated simuliid species included at least one new species of the genus Helodon. The new species of Prosimulium is tentatively considered endemic to the mountains of northern Algeria but might be expected in the mountains of eastern Morocco and northern Tunisia and perhaps in Sicily. If its endemic status holds, it would be the only nominal species of black fly unique to Algeria.

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.

Biodiversity and chorology of aquatic beetles (Coleoptera: Elmidae and Hydraenidae) in Kabylia (central-north Algeria). New records and updates.

This work presents a list of water beetles of the families Hydraenidae and Elmidae occurring in Kabylia (central-north of Algeria) based on an exhaustive review of literature (1872-2016) and on more than 2126 individuals collected during field campaigns (2013-2015). Twenty-five species belonging to nine genera of Hydraenidae and Elmidae are here recorded from a total of 25 sites. Ochthebius (Ochthebius) bifoveolatus Waltl, 1835 is here recorded for the first time from Algeria; Hydraena leprieuri, Limnebius pilicauda, and Limnius intermedius are new records for Kabylia.                A biogeographical analysis shows that the Hydraenidae and Elmidae from Kabylia are essentially Mediterranean (80%) and Palaearctic (20%) elements. Elements with wider distributions are absent.

Marthamea bayae, a new species of stonefly from Algeria (Plecoptera: Perlidae).

A new species of the perlid genus Marthamea Klapálek, M. bayae sp. n. from Algeria is described and illustrated based on the morphology of adults and larvae. This is the first known record for the genus from North Africa.
