“…Apparently, M. molossus from the Caatinga are slightly larger than those of the Atlantic Forest of southeastern Brazil, where the average forearm length varies from 37.5 to 39.0 mm (Dias et al 2002;Dias and Peracchi 2008). Body size may vary among populations of the same bat species according to biome type and latitude (Nargosen and Tamsitt 1981;Aspetsberger et al 2003), and bat populations from the Caatinga often have larger body values comparing to populations from other Brazilian biomes, like Cerrado (Willig 1983), Pantanal, and Atlantic Forest (Louzada and Pessôa 2013).…”

Here I report the first record of the bat Molossus molossus in the state of Rio Grande do Norte, northeastern Brazil. A colony of this species was recorded in the urban area of Lagoa Salgada, in the attic of a building. In January 2014, I captured 90 individuals of M. molossus using mist nets around the roost. The present record extends the distribution of M. molossus to far-northeastern Brazil and adds a new marginal occurrence site for this species. DOI: 10.15560/10.6.1520 Figure 1. Day roost of a Molossus molossus (Chiroptera: Molossidae) colony in a school building in the urban area of Lagoa Salgada, state of Rio Grande do Norte, northeastern Brazil, with a general view of the surrounding area (a) (Satellite image source: Google Earth ® ) and frontal (b) and lateral views (c and d) of the roost, where mist nets were set to capture bats. 1521Barros | First record of Molossus molossus in Rio Grande do Norte, Brazil caught on the nets. Among the captured individuals, the sex ratio was close to 1:1 (46 males and 44 females) ( Table 1). Approximately 32% of the individuals were juvenile, and among the adults 65% were reproductive. Of all adult females (N = 28), 35% were pregnant and lactating, 18% were pregnant, and 7% were lactating; of all adult males (N = 33), 70% had scrotal testes. The average forearm length of adults was 41.90 mm (standard deviation = 1.03) for males and 41.67 mm (standard deviation = 1.09) for females, and the average body mass was 15.1 g (standard deviation = 1.4) for males and 14.2 g (standard deviation = 1.2) for females.The individuals were released at the capture site at the same night, except ten specimens (five males and five females) collected as vouchers. These specimens were killed by inhaling sulfuric ether, fixed in formaldehyde (10% solution), preserved in ethanol (70% solution), and deposited in the Mammal Collection of the Universidade Federal de Pernambuco (Numbers UFPE 3068, UFPE 3069, UFPE 3070, UFPE 3071, UFPE 3072, UFPE 3073, UFPE 3074, UFPE 3075, UFPE 3076, and UFPE 3077). The specimens were taxonomically identified according to the keys and descriptions of Gregorin and Taddei (2002), Gregorin et al. (2011), and Costa et al. (2013). The diagnostic features supporting the identification of these specimens as M. molossus include: (1) relatively large forearm length (39.25-43.34 mm) comparing to the others "small" Molossus; (2) elongated skull, narrow rostrum, and non-globose brain case; (3) infraorbital foramen opening more frontally than laterally; (4) elongated (non-spatulate) upper incisors with pincer-like tips; and (6) long (≌ 5 mm) dorsal hairs with a white basal band.The present record extends the distribution of M. molossus in northeastern Brazil and provides a new (Figure 3). These data indicate that the distribution of M. molossus probably includes the entire state of Rio Grande do Norte, which should be confirmed by further studies. In the tropics, the reproduction of insectivorous bats is associated with rainfall, which influences prey avail...
