Contemporary distributions of Panurginus species and subspecies in Europe (Apoidea: Andrenidae: Panurginae)

Contemporary distributions of Panurginus species and subspecies in Europe (Apoidea: Andrenidae: Panurginae) The largest number of Old World Panurginus Nylander, 1848 species is distributed in the West- Palaearctic. The genus is absent in Africa and rather rare in the East-Palaearctic. Warncke (1972, 1987), who is the main author treating Palaearctic Panurginae in the last decades, subdivided Panurginus into a small number of species, including two principal taxa admitting for each a very large number of subspecies: Panurginus brullei (Lepeletier, 1841) and Panurginus montanus Giraud, 1861. Following recent works, the two latter are in fact complexes of closely related species. In the West-Palaearctic context, distributions of certain species implied in these complexes appear as very singular, distinct of mostly all other Panurginae ranges and highly interesting from a fundamental point of view. Based on a cartographic approach, the causes which influence (or have conditioned, in the past) the observed ranges of these species are discussed.
