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.
Descripción
The authors wish to thank Santiago Villamarín and Christian Villamarín for their hospitality and support during our field studies in Carchi, Ecuador during February of 2017. Xavier Amigo, Nature Experience, and Jolanda Huisman also provided very generous support in the field. This study was supported by Universidad de Las Americas project AMB.BRT.17.005 “Diversidad y Distribucion de Trichoptera de Ecuador,” Minnesota Agricultural Experiment Station projects MIN-17-017 and 17-029, and USDA National Institute of Food and Agriculture project 1013092. ERG was funded through a doctoral fellowship from Cienciactiva, Consejo Nacional de Ciencia, Tecnologia, e Innovacion Tecnologica Peru (contract 277-2015- FONCECYT). The Ministerio del Ambiente, Ecuador, granted the study permit (MAE-DNB-CM-2016-0045). This support is gratefully acknowledged. We thank Dr Brian Armitage, Dr Tatiana Arefina-Armitage, Dr Ana Previsic, and an anonymous reviewer for providing very useful suggestions to improve the manuscript.
