Geoffroy St. Hilaire, 1824 nomen oblitum Geoffroy St. Hilaire, I. (1824) Sur les Vespertilions du Brésil . Annales de Sciences naturelles Paris, 3: 443. Valid name: Myotis levis (I. Geoffroy St. Hilaire, 1824) , nomen protectum Note: V . polythrix was treated by Simmons (2005: 510) as a synonym for Myotis levis (I. Geoffroy St. Hilaire, 1824) , Ann. Sci. Nat., 3: 444. Due to page priority the first available name is polythrix ( polythrix on p. 443, levis on p. 444). According to ICZN (1999) article 23.9.1. prevailing usage must be maintained when the following conditions are both met: 23.9.1.1. the senior synonym or homonym has not been used as a valid name after 1899, and 23.9.1.2. the junior synonym or homonym has been used for a particular taxon, as its presumed valid name, in at least 25 works, published by at least 10 authors in the immediately preceding 50 years and encompassing a span of not less than 10 years. The name [ Myotis ] polythrix has not been used as valid name after 1899, whereas the name [ Myotis ] levis has been by Anderson et al. (1982) , Baud & Menu (1993) , Capllonch et al. (1997) , Morando & Polop (1997) , Lopez-Gonzalez (1998) , Braun & Diaz (1999) , Diaz & Barquez (1999) , Hoofer & Van den Bussche (2001) , Lopez-Gonzalez et al. (2001) , Sanabria & Quiroga (2001) , Villavicencio et al. (2001) , Arzua et al. (2002) , Fenton & Bogdanowicz (2002) , Lunaschi (2002) , Merino et al. (2003) , Miretzki (2003) , Reis et al.

(2005) , Esberard & Bergallo (2005) , Simmons (2005) , and Miranda et al. (2006) . According to ICZN (1999) article 23.9.2. the younger but valid name levis is a nomen protectum, and the older but invalid name polythrix a nomen oblitum.
