Our own investigations in North Eastern Algeria and data from other authors revealed the presence of 382 species of Bees belonging to 55 genera.These species were distributed into six families: Colletidae (2 genera, 25 species), Melittidae (3 genera, 9 species), Halictidae (8 genera, 60 species), Andrenidae (5 genera, 77 species), Apidae (17 genera, 111 species) and Megachilidae (20 genera, 100 species). Compared to the west Palaearctic fauna, long tongued Bees were more represented with 211 species against 171 for those with a short tongue in Algeria. In West Palaearctic the short tongued Bees constituted the majority: 253 species in Baden-Wurtenberg (Germany) against 137 long tongued species. There is a greater number of Megachilini and Osmiini (Megachilidae) in Algeria whereas in Western Europe, Bumblebees of the genus Bombus (Bombini, Apidae) are the most diverse.frArticle
