Eleven species of Heteroptera in seven families, including the first record of the family Alydidae, are reported from the Galápagos Islands. The first Galápagos Island records are given for the following: Alydidae [Neomegalotomus parvus (Westwood)]; Coreidae [Vazuezitocoris andinus Brailovsky = Anasa mimetica Brailovsky]; Miridae [Halticus bractatus (Say)]; Pentatomidae [Mecidea minor Ruckes, Nezara viridula (Linnaeus), Piezodorus guildinii (Westwood), and Podisus distinctus Stål]; Reduviidae [Heza ephippium (Lichtenstein)]; Rhopalidae [Niesthrea ashlocki Froeschner, Niesthrea sidae (Fabricius)]; and Tingidae [Leptobyrsa decora Drake]. For each species, we give a diagnosis, dorsal photograph, a summary of the distribution and host plants, and provide information to facilitate identification. With the discovery of these new taxa and the correction of several misidentifications, the number of Heteroptera known from the Galápagos Islands is increased from 20 families, 71 genera, and 131 species to 21 families, 76 genera, and 140 species.
