Two new species in the rare, endemic Neotropical caddisfly genus Amphoropsyche Holzenthal, 1985 are described from Ecuador (A. carchisp. n.) and Peru (A. matsigenkasp. n.) bringing to 17 the number of species known in the genus. Almost all species are known from only a few individuals and from even fewer localities. The new species belong to a group of 10 other species that have tergum X in the male genitalia divided into a mesal process and a pair of lateral processes. Amphoropsyche carchi can be separated from those species by the rounded mesal concavity, the short mesobasal lobe, and the short 2nd article of the inferior appendage, while A. matsigenka can be diagnosed by the very slender and straight inferior appendage, which bears a pair of spine-like mesoventral projections. We also present a new record for Amphoropsyche tandayapa Holzenthal & Rázuri-Gonzales, 2011, from Ecuador, previously known only from the male holotype.
