Artibeus fimbriatus Gray, 1838

Fig. 18

Taxonomy. Five species of Artibeus Leach, 1821 are found in Brazil: A. concolor Peters, 1865 , A. fimbriatus Gray, 1838 , A. lituratus (Olfers, 1818) , A. obscurus (Schinz, 1821) and A. planirostris (Spix, 1832) ( Nogueira et al. 2014) . Artibeus concolor is comparatively smaller (forearm <53 mm in A. concolor , and> 55 mm in the other species), and with tricolored dorsal fur (bicolored in the congeners) ( Zórtea 2007, Marques-Aguiar 2008, Díaz et al. 2016). The field identification of the species of Artibeus captured in PECB was based on a set of external characters provided by Koepcke and Kraft (1984), Marques-Aguiar (1994), Lim and Engstrom (2001), Haynes and Lee Jr (2004), Hollis (2005), Zortéa (2007), Marques-Aguiar (2008), Dias and Peracchi (2008) and Araújo and Langguth (2010), such as: base of noseleaf (attached or separate from upper lip), brightness of facial stripes, presence/absence of fur on the dorsal side of forearm, corporal size, presence/absence of fur on the dorsal side of uropatagium, presence/absence of ventral frosting and length of dorsal fur. Artibeus fimbriatus can be distinguished from A. lituratus by the presence of sparse hairs on the dorsal side of the uropatagium, which is densely furred on A. lituratus , presence of ventral frosting (absent in A. lituratus ), weakly marked facial stripes (brilliant and well markedwell-marked in A. lituratus ), longer dorsal fur, close to 8 mm (6–8 mm in A. lituratus ), and sparse hairs on the dorsal side of the forearm, which is densely furred in A. lituratus ( Koepcke and Kraft 1984, Marques-Aguiar 1994, 2008 Haynes and Lee Jr 2004, Dias and Peracchi 2008, Araújo and Langguth 2010).

Artibeus fimbriatus can be distinguished from A. planirostris by its larger size, the presence of sparse hairs on the dorsal side of the uropatagium and forearm (almost naked in A. planiostris ), by the base of the noseleaf attached to the upper lip (separated in A. planirostris ), and longer dorsal fur, close to 8 mm (6–8 mm in A. planirostris – Koepcke and Kraft 1984, Marques-Aguiar 1994, 2008, Haynes and Lee Jr 2004, Hollis 2005). Artibeus fimbriatus and A. obscurus differ in size (larger forearm in A. fimbriatus ); the length of dorsal fur (close to 8 mm in A. fimbriatus and 8–10 mm in A. obscurus ); base of the noseleaf attached to the upper lip in A. fimbriatus (totally separated in A. obscurus ); presence of sparse hairs on the dorsal side of the uropatagium in A. fimbriatus (almost naked on A. obscurus ); ventral frosting more evident in A. obscurus ; and presence of sparse hairs on the dorsal side of the forearm in A. fimbriatus (densely furred on A. obscurus – Marques-Aguiar 1994, 2008, Haynes and Lee Jr 2004, Dias and Peracchi 2008, Araújo and Langguth 2010).

The PECB specimens (ZSP 027, 037; see Table 6 for measurements) identified as A. fimbriatus have bicolored dorsal fur, with pale brown basis and grayish brown tips, and ventral fur weakly bicolored, with pale basis and frosted tips. Dorsal fur averaging 8.5 mm (7.9–9.3 mm), the forearm and uropatagium are sparsely furred, the noseleaf is attached to the upper lip, the ears and tragus are brown, and the facial stripes are poorly marked.

Distribution. In Brazil, the species is recorded in all biomes, except Amazon, occurring in Distrito Federal and in the states of Ceará, Pernambuco, Sergipe, Bahia, Minas Gerais, Espírito Santo, Rio de Janeiro, São Paulo, Mato Grosso do Sul, Paraná, Santa Catarina, Rio Grande do Sul, Paraíba and Maranhão ( Reis et al. 2013, Oliveira and Aguiar 2015, Olímpio et al. 2016, Zeppelini et al. 2016). In São Paulo, the species is recorded in the central, south and southeastern regions ( Garbino 2016).

Field observations. We recorded 46 specimens, 37 of which (14 males and 23 females) were taken in ground-level mist-nets set in sampling sites M7, M14, M16, M18 M20, M21, M24, M26, M27, M28, M32, M35, M36 and M38; eight (4 males and 4 females) in mist-nets elevated 8 m in sampling sites M14, M24, M26, M28 and M31; and one adult female on a building roof, in sampling site S2 (Appendix 1). Captures occurred in November, February, March, April, May, June, July and September. Lactating females were netted in February, March and July; pregnant females in February, March and November; and juveniles in February, March, April, May and July.
