Abstract

Three genera (Isodrapetis Collin, Chersodromia Walker, Elaphropeza Macquart) and six species of Tachydromiinae (Hybotidae) are recorded from the Galápagos Islands. One new species of Isodrapetis (I. meridionalis sp. n.) and three new species of Chersodromia (C. floreana sp. n., C. galapagensis sp. n., C. isabela sp. n.) are described. Elaphropeza zonalis (Curran) is redescribed and a fourth species of Chersodromia is identified based on a single female specimen. A key to all Galápagos species is provided. Isodrapetis is recorded for the first time outside of New Zealand. The affinities of the Galápagos Tachydromiinae to the New World fauna are discussed.
