Abstract

A new genus and species of Philopotamidae (Trichoptera), Sumacodellaelongata, is described from the southern slope of Volcán Sumaco in Ecuador. This new genus differs from other philopotamid genera by having very elongate, narrow anterolateral apodemes on segment IX and the inferior appendages, a very elongate and narrow tergum X, and a very elongate, tubular phallus. In addition, two new species of Wormaldia are also described and illustrated from Sumaco as well as three new Chimarra (Chimarra), one new Chimarra (Curgia), and one new Chimarra (Otarrha) from the eastern and western slopes of the Ecuadorian Andes.
