The Tortricidae (Lepidoptera) of the Galapagos Islands, Ecuador

Abstract

Sixteen species of Tortricidae are recorded as being established on the Galapagos Archipelago, including nine that are described as new by Razowski & Landry and presumed to be endemic (Hedya brunneograpta, Eccopsis galapagana, E. floreana, Megalota johni, Episimus alcedanus, Epinotia microscyphos, Proteoteras atromacula, Coniostola isabelae, and Dichrorampha galapagana). Two other endemic tortricids have been described from the Galapagos by Meyrick (Platynota colobota and Crocidosema synneurota). The other five species are either native or recently introduced by humans (Bactra philocherda Diakonoff, Endothenia eidolon Razowski & Pelz, Episimus transferranus (Walker), Epinotia lantana (Busck), Strepsicrates smithiana Walsingham). Four additional species are reported to have been intercepted by the Galapagos quarantine system (Anopinella sp., Lasiothyris sp., Transtillaspis sp., and Epinotia cosmoptila (Meyrick)), but they are apparently not established in the Galapagos. Hedya, Eccopsis, Proteoteras, and Coniostola are recorded for the first time from South America. Olethreutes olorina Walsingham is transferred to Hedya Hübner.
