Primeiro registro da família Furipteridae (Mammalia, Chiroptera) para o Estado do Rio de Janeiro, Brasil

First record of the smoky bat Furipterus horrens (F. Cuvier, 1828) (Mammalia: Chiroptera) in the state of Espírito Santo, southeastern Brazil

“…The weight was 1 g and it was taken with a Pesola scale (precision= 0.5 g). These measurements are very similar to those obtained in previous works (Husson 1962(Husson , 1978Simmons and Voss 1998;Pol et al 2003). Intraspecific divergence between the sample from Espírito Santo and from the Guianas varied from 2.1% to 2.5%, while interspecific divergence varied from 21.2% to 25.4%.…”

First record of the Vulnerable bat Furipterus horrens (Cuvier, 1828) (Chiroptera: Furipteridae) in the state of Paraná, southern Brazil

“…cave) used as roosting spots (Trajano 1984, Trajano & Gnaspini-Netto 1990, Bredt et al 1999, Silva et al 2001, Esbérard et al 2005, Sato et al 2011, Leal et al 2014). In addition, F. horrens have been captured from their roosting spots either by hand or using insect nets in the states of Ceará, Espírito Santo, and Rio de Janeiro (Pol et al 2003, Fabián 2008, Duda et al 2012. Similar results were obtained by Simmons and Voss (1998) in Paracou, French Guiana, in which 12 out of 13 specimens of F. horrens recorded were caught with active search and only 1 specimen was shot during flight.…”

“…The external and craniodental measurements of our specimen fall within the range reported in the literature: forearm length = 36.15 mm; ear length = 9.45 mm; tragus length = 3 mm; tail length = 30.35 mm; hind foot length = 6.35 mm; greatest length of the skull = 12.32 mm; condyloincisive length = 11.31 mm; condylocanine length = 10.49 mm; basal length = 10.32 mm; zygomatic breadth = 7.42 mm; mastoid breadth = 6.32 mm; braincase breadth = 6.09 mm; postorbital breadth = 3.28 mm; breadth across upper molars = 4.66 mm; maxillary toothrow length = 4.48 mm; mandibular length = 8.16 mm; mandibular toothrow length = 5.40 mm; and weight = 4 g (Husson 1962, Uieda et al 1980, Pol et al 2003, Reis and Gazarini 2007, Gardner 2008, Sato et al 2011, Novaes et al 2012, Duda et al 2012, Leal et al 2014). …”

“…Although active search during daylight hours has been used successfully to detect F. horrens (Simmons and Voss 1998, Pol et al 2003, Esbérard et al 2006, Gregorin et al 2008, Noaves et al 2012, this method was not effective to find this species at Gruta do Bacaetava. This might be attributed to the presence of small gaps between rocks and passages that are too small to allow access to a collector but not to a small bat such as F. horrens.…”

“…Although Furipterus horrens has been recorded in the hollows of fallen trees (Voss and Emmons 1996) and buildings (Fabián 2008, Duda et al 2012), this species is more frequently found in caves as showed elsewhere (Uieda et al 1980, Trajano 1984, Trajano and GnaspiniNetto 1990, Bredt et al 1999, Portfors et al 2000, Silva et al 2001, Pol et al 2003, Esberárd et al 2005, Tavares et al 2010, Sato et al 2011, Novaes et al 2012, Leal et al 2014, Felix et al 2016. Furthermore, most of the records obtained outside caves were based on small colonies of 1-6 specimens while records obtained in caves were based on large colonies ranging from 10-250 specimens (Uieda et al 1980, Bredt et al 1999, Silva et al 2001, Novaes et al 2012.…”
