Abstract

Species of Braggia Gillette and Palmer (Hemiptera: Aphididae: Aphidinae: Aphidini) feed on various buckwheat, Eriogonum Michx. (Polygonaceae), species in western North America. Two new species, Braggia columbiana Pike n. sp. from Washington and Oregon and Braggia longicauda Pike n. sp. from Washington, Oregon, and northern California, are proposed. Descriptions, diagnoses, illustrations, mitochondrial cytochrome c oxidase subunit 1 “barcode” sequences, a key to the species of Braggia, and notes on biology, distribution, and parasitoid associations are provided.

Résumé

Les espèces de Braggia Gillette et Palmer (Hemiptera: Aphididae: Aphidinae: Aphidini) se nourrissent de diverses espèces d’Eriogonum Michx. (Polygonaceae) dans l’ouest de l’Amérique du Nord. Nous proposons deux nouvelles espèces, Braggia columbiana Pike n. sp. des états de Washington et d’Oregon et Braggia longicauda Pike n. sp. du Washington, de l’Oregon et du nord de la Californie. Nous fournissons des descriptions, des illustrations, des séquences des “codes à barres” COI et une clé des espèces de Braggia, ainsi que des notes sur leur biologie, leur répartition et leurs associations de parasitoïdes.
