Abstract
A new genus and species of Hebridae, Archaeohebrus alius gen. et sp. nov., is described from the Late Cretaceous Kachin amber. The new genus is assigned to the Hebridae based on the bucculae elevated posteriorly forming a pair of ridges, short transverse mesoscutellum, and triangular metanotal elevation. This new genus differs from other genera of Hebridae in the forewing having three cells, three-segmented tarsi, and terminally inserted genital segments. The new genus might represent the most basal lineage of Hebridae, and the forewing venation of this Cretaceous hebrids hints at a close relationship between the Mesoveliidae and Hebridae.
