PROC. ENTOMOL. SOC. WASH. 99(2), 1997, pp. 348-358 REVIEW OF THE BLASTOBASINAE (LEPIDOPTERA: GELECHIOIDEA: COLEOPHORIDAE) OF THE GALAPAGOS ISLANDS David Adamski and Bernard Landry (DA) 6033 Majors Lane, Apt. #2, Columbia, MD 21045, U.S.A.; (BL) Department of Environmental Science, Policy and Management, 201 Wellman Hall, University of Cali-fornia, Berkeley, CA 94720, U.S.A. Abstract. — Calosima darwini, new species, is described from the Galapagos Islands, Ecuador, and is the first member of the genus known beyond North America. Auximobasis normalis Meyrick, 1918 is a senior synonym of Blastobasis crotospila Meyrick, 1926, and is redescribed and transferred to Blastobasis Zeller, 1855. A key and illustrations of adults, including male and female genitalia, are provided for the two species of Blasto-basinae known from the Galapagos Islands. Key Words: South America, Ecuador, Galapagos, Lepidoptera, Gelechioidea, Coleo-phoridae, Blastobasinae, Calosima, Blastobasis The Lepidoptera of the Galapagos Is-lands are known incompletely. Although a number of collections have been made and reported, they have been restricted to the larger moths and the butterflies (Beebe 1923, Butler 1877, Schaus 1923, Hayes 1975). Consequently, the microlepidoptera remain known only partially. Eleven spe-cies were recorded by Meyrick (1926), and four were added by Linsley and Usinger (1966) and Linsley (1977). Recent collec-tions by Robert Silberglied in 1969 and more recently by Bernard Landry in 1989 and 1992 have resulted in considerably more specimens of microlepidoptera than have been available previously. For exam-ple, Landry amassed more than 3,000 spec-imens of microlepidoptera in 5 months of collecting on the Galapagos Islands. Studies of this material have yielded publications on Pterophoridae (Landry and Gielis 1992, Landry 1993), Choreutidae (Heppner and Landry 1994a), Heliodinidae (Heppner and Landry 1994b), and the present paper on Coleophoridae (Blastobasinae). The Blastobasinae are probably one of the most commonly collected groups of Ge-lechioidea in the Americas. Yet this sub-family may be one of the least known to science. Generally, species are drab with few, if any, diagnostic wing color patterns, making identifications difficult unless the genitalia are examined. Since Meyrick (1894) the Blastobasinae have been considered to be a monophyletic group. Recent studies (Adamski and Brown 1989, Hodges, in press) have corroborated this notion and have rigorously established relationships of the Blastobasinae within Gelechioidea. In this work the Blastobasi-dae {sensu Adamski and Brown, 1989) are treated as a subfamily within the Coleo-phoridae. Materials and Methods Collecting methods and information on the islands visited are found in Landry and Gielis (1992) and Landry (1993). Speci-mens were prepared (pinned and mounted)
