Of thirteen species listed one genus, three Euliini species (Pseudomeritastis emphanes, Netechmodes landryi, Thalleulia gracilescens), three species of Archipini (Clepsis parva, C. parassensus, C. assensiodes), two species of Atteriini (Sisurcana leptina, Anacrusis rubida) and one of Chlidanotini (Monortha procera) are described as new. Female of Henricus metalliferus RAZOWSKI & PELZ is described.
recognized as a separate species) along with three unidentified species of Epinotia, at least one of which did not belong to that genus. Then Meyrick (1926) described Crocidosema synneurota and Platynota colobota, without recording other species. These three taxa were simply listed by Linsley &Usinger (1966), andLinsley (1977) did not add any new records. In their papers on introduced insects in the Galapagos, Peck et al. (1998) and Causton et al. (2006) mentioned C. plebejana and S. smithiana, as well as Bactra philocherda Diakonoff and Episimus transferranus (Walker). Perry & de Vries (2003) recorded C. plebejana as widespread in the Galapagos and feeding on Acacia sp. (Fabaceae).Tortricidae larvae usually feed in hiding, either in tied leaf shelters or inside plant tissue; several species are polyphagous. In the Galapagos one or more host plants are known for only three species, and the host plants of two more widespread species are known from elsewhere.In addition to the species treated below, four others along with Epinotia lantana (Busck) were reared from larvae intercepted with various goods by the quarantine system of the Galapagos Islands (SICGAL). They were identified by BL and JR as follows: Anopinella sp. (Euliini), Lasiothyris sp. (Cochylini), Transtillaspis sp.(Euliini, reared from apples), and Epinotia cosmoptila (Meyrick, 1917) (Eucosmini), the last of which representing a new record for the western part of the South American continent. We do not believe that these four are established on the Galapagos.However, the unique female illustrated as Fig. 34 (wingspan: 24 mm), collected on Isabela, Volcan Darwin. 630 m in elevation (MHNG [ENTO] No. 3094) represents an unknown species that is probably established on the archipelago; it is not described here owing to the paucity of material.Among the 28 families of Lepidoptera recorded from the Galapagos, the Tortricidae and Geometridae occupy the fourth rank in terms of species numbers, behind the Noctuidae, Pyralidae, and Gelechiidae. They are followed by the Sphingidae and Pterophoridae, which have 15 species each.
MATERIAL AND METHODSThe responsibilities of the authors in this project were as follows. The first author (JR) made most taxonomic decisions and specimen identifications, and prepared all new species descriptions and most diagnoses. BL collected most of the specimens during five expeditions to the
Tortricidae collected in RRo Gualaceo Valley with special attention to their elevational distribution are listed. Three genera and 34 species are described as new: Henricus cerussatus sp.n.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
