ResumoRio de Janeiro (Fig. 1) is one of the most well studied states of Brazil in regard to its bat fauna, due to the concentration of universities and researchers (Bergallo et al., 2003). The first bat mentioned in the literature for Rio de Janeiro was the common vampire bat, Desmodus rotundus, by Hans Staden (1557, apud Tribe, 1987). However, the first scientific citation was of Anoura caudifer (E. Geoffroy, 1818), for which the State of Rio de Janeiro is the type-locality (Lima, 1926). Until the 1970s, most research on bats was done by capturing the animals directly in their refuges or by shooting. The use of mist nets greatly increased the efficiency of capture (see Handley, 1967), resulting in an increase in the knowledge of bat biology and distribution in this geographical unit (Fig. 2). The first reference to the use of mist nets in Rio de Janeiro State dates from 1967 (Peracchi and Albuquerque, 1971). The first species list for the state, published by Peracchi and Albuquerque (1971), included 12 new records, subsequently complemented with another five species (Peracchi and Albuquerque, 1986). In the last 40 years, this list grew rapidly (Fig. 2) due to an increase in the number of researchers, as well as institutions interested in the study of bats. In 1997, a meeting was held to produce a list of threatened species and analyze their conservation status (Bergallo et al., 2000); 62 species were recognized for the Rio de Janeiro state (Rocha et al., 2004). Currently, Rio de Janeiro is the most thoroughly sampled state in Brazil, in terms of bats (Bergallo et al., 2003). However, even considering there are inventories in more than 30 different areas, several sites in the state remain poorly sampled, such as the northwestern and the montane areas. Since the 1997 list, new surveys of previously unexplored areas have confirmed the presence of Furipterus horrens in the south (Pol et al., 2003), Myotis levis in a montane area in the south (A. Pol, personal communication), Neoplatymops mattogrossensis and Uroderma bilobatum in the northern part of the state (Avila et al., 2001) and Micronycteris hirsuta (Esberard, 2004a) and Tonatia brasiliensis (unpublished results) in the northern and central part of the state. Additionally, increased sampling efforts in previously sampled areas, such as the Macico da Tijuca, have confirmed the occurrence of species not previously recorded, despite exRESEARCH ON BATS IN THE STATE OF RIO DE JANEIRO, SOUTHEASTERN BRAZIL
