Abstract:

A new genus and species of Philopotamidae (Philopotaminae), Aymaradella boliviana, is described from the Bolivian Andes of South America. The new genus differs from other Philopotaminae by the loss of 2A vein in the hind wing and, in the male genitalia, the synscleritous tergum and sternum of segment VIII, and the elongate sclerotized dorsal processes of segment VIII. The first record of Hydrobiosella (Philopotaminae) in the New World is also provided with a new species from the Andes of Ecuador, Hydrobiosella andina. In addition, a new species of the Neotropical genus Chimarrhodella (Chimarrinae), Chimarrhodella choco, is described from the Choco-Andean region of Ecuador, and Chimarrhodella peruviana (Ross) is recorded from Ecuador for the first time. Lastly, Wormaldia imbrialis (Philopotaminae), new species, is described, also from the Ecuadorian Choco.
