Two new species of Chionodes Hübner from Ecuador, with a summary of known Galapagos records of Gelechiidae (Lepidoptera)

Abstract

Two new species of the genus Chionodes Hübner, 1825 (Lepidoptera, Gelechiidae) from Ecuador are described and illustrated. Chionodes stefaniae sp. n. occurs in the Galapagos on the islands of Floreana, Isabela, Pinta, Pinzon, Rabida, San Cristobal, and Santa Cruz, where it is believed to be endemic. Chionodes manahiensis sp. n. occurs on the Ecuadorian coast in Machalilla National Park. The previous Galapagos records of Aristotelia howardi Walsingham, 1909, and Stegasta bosqueella Chambers, 1875 were erroneous. Stegasta zygotoma Meyrick, 1917 is reported from the Galapagos for the first time. Altogether, five species records of Gelechiidae are now considered valid for the Galapagos.
