Abstract

In the present study the imagos of Harpagobaetis Mol and Tomedontus Lugo-Ortiz & McCafferty are described for the first time. They can be differentiated from other genera of Baetidae by the following combination of characteristics: Harpagobaetis, forewing with paired marginal intercalary veins; hind wing present with two complete longitudinal veins; costal projection of hind wing pointed, placed in the basal third of anterior margin, cross veins absent; forceps three-segmented, segment I with bulbous base, segment III long, about 3 × as long as wide; Tomedontus, dorsal portion of turbinate eye circular; forewing with paired marginal intercalary veins; hind wing absent; forceps three-segmented, segment II with strong medial projection; subgenital plate without projection.
