Abstract
Eucera (Cubitalia) breviceps (Friese, 1911), hitherto only known from Turkey and Syria, was discovered in the southern part of Massif Central (France), in the “Grands Causses” area, a few years ago. It has been found to be distributed throughout it, also present in the French Alps and Italy (Valle d’Aosta, Abruzzo) as well as in southwestern Bulgaria and northern Greece. Our article presents the corresponding data, originated from field work and examination of material in collections, and gives new data for Turkey from material in the collection of the Oberösterreichisches Landesmuseum, Linz (Austria). Several ecological traits of E. breviceps are discussed. We especially highlight the close association between E. breviceps and the plant genus Onosma L. (Boraginaceae), based on literature and our field observations. Both their ecological requirements and their interactions illustrate the complexity of such relationships and their potential vulnerability in the context of global change. Through this remarkable example of an oligolectic interaction, we aim to promote a better consideration of pollinators, notably bees, and pollinator networks in conservation biology.

Premières observations d’Eucera (Cubitalia) breviceps (Friese, 1911) en Italie et en France, avec des informations actualisées sur la répartition et l’écologie de l’espèce (Hymenoptera : Anthophila : Apidae)

Résumé
Eucera (Cubitalia) breviceps (Friese, 1911), jusqu’alors connue de Turquie et de Syrie, a été découverte dans la région des Grands Causses (Massif central) dans le sud de la France il y a quelques années. Elle s’est révélée y être assez largement distribuée, et est également présente dans les Alpes françaises, dans le Val d’Aoste et dans les Abruzzes en Italie, dans le sud-ouest de la Bulgarie et le nord de la Grèce. Notre article présente les données correspondantes provenant de nos prospections de terrain ainsi que de l’examen de spécimens en collection, et apporte de nouvelles données pour la Turquie issues de la révision de matériel au Muséum de Linz en Autriche. Nous y présentons différents éléments de l’écologie d’E. breviceps et, en particulier, les interactions étroites qu’elle entretient avec les plantes du genre Onosma L. (Boraginaceae), sur la base de la bibliographie et de nos observations in situ. Leurs exigences écologiques respectives et leurs interactions illustrent la complexité de telles relations et leur vulnérabilité dans le contexte des changements globaux. À travers la présentation de cet exemple remarquable d’oligolectisme, nous visons une meilleure prise en considération des pollinisateurs, notamment des abeilles, et des réseaux plantes-pollinisateurs dans le champ de la biologie de la conservation.
