Abstract

Electroborus brighti, new genus, new species (Coleoptera: Curculionidae: Scolytinae) is described based on two specimens from Dominican amber, which represents the first Hylesinini found in Dominican amber. A phylogenetic analysis of 24 Hylesinini species and a Strombophorus Hagedorn species based on morphological characters suggests E. brighti is not related to the Neotropical genus Phloeoborus Erichson, but shares a close affinity to African Hylesinini genera. The discovery of this new genus adds to the evidence that tropical South America and Africa shared similar faunas throughout evolutionary history. Although many Old World taxa have become extinct in the New World, the existence of E. brighti among Recent faunas is a possibility, given that the South American and African scolytine faunas are relatively poorly studied.

Résumé

Electroborus brighti, nouveau genre, nouvelle espèce, (Coleoptera: Curculionidae: Scolytinae) est décrite à partir de deux spécimens trouvés dans l'ambre dominicaine, et représente le premier Hylesinini trouvé dans l'ambre dominicaine. L'analyse phylogénétique de 24 espèces de Hylesinini et une espèce de Strombophorus Hagedorn basée sur des caractères morphologiques suggère que E. brighti n'est pas liée au genre néotropical Phloeoborus Erichson, mais partage une affinité proche des genres africains de Hylesinini. La découverte de ce nouveau genre ajoute une preuve que l'Amérique du Sud tropicale et l'Afrique partagent une faune semblable à travers l'histoire évolutive. Bien que de nombreux taxons du Vieux Monde se soient éteints dans le Nouveau Monde, l'existence de E. brighti parmi les faunes récentes est une possibilité, étant donné que la faune de scolytes d'Amérique du Sud et d'Afrique est relativement peu étudiée.
