New genus of minute Berothidae (Neuroptera) from Early Eocene amber of British Columbia

  • S. Bruce Archibald (a1) and Vladimir N. Makarkin (a2)

Microberotha macculloughigen. nov. and sp. nov. from Early Eocene Okanagan Highlands amber of Hat Creek, British Columbia, Canada, is described. This new genus and species represents one of the smallest members of the family Berothidae and the first occurrence of the family in the New World Tertiary. The systematic position of the genus Microberotha within the family is rather unclear, but the structure of the male genitalia indicates a close association with the subfamily Cyrenoberothinae. Stratigraphy and palaeoenvironment of the Hat Creek locality are briefly discussed.


On trouvera ici la description de Microberotha macculloughigen. nov. et sp. nov. provenant de l'ambre de l'éocène inférieur de Hat Creek, dans les hautes terres de l'Okanagan, Colombie Britannique, Canada. Cet insecte appartenant à un nouveau genre et une nouvelle espèce est l'un des plus petits de la famille des Berothidae; il représente aussi la première mention de la famille du tertiaire du Nouveau Monde. La position systématique de la genre Microberotha dans la famille est plutôt incertaine, mais les organes sexuels mâles indiquent une forte association avec la sous-famille des Cyrenoberothinae. La stratigraphie et le paléoenvironnement du site de Hat Creek font l'objet d'une courte discussion.
