Eptesicus furinalis, (D'Orbigny and Gervais, 1847) (D'Orbigny and Gervais, 1847)

RESULTS View in CoL

The specimen was a non-lactating adult female (♀), with dark chestnut dorsal pelage, yellow venter, small brain box, the rostrum is flat, undeveloped sagittal crest, second upper incisor tooth half the size of the first, elongated snout, short, rounded ears with points, a pointed tragus, and hairless membranes. The morphometric measurements were: right forearm = 43.00 mm, left forearm = 43.5 mm, tragus = 7 mm, ear = 14 mm, and foot = 9 mm. The weighed 9 g and had 32 teeth, with a dental formula of 2/3 incisors, 1/1 canines, 1/2 premolars, and 3/3 molars ( Figs. 1 View Figure 1 and 2 View Figure 2 , Table 1 View Table 1 ).

A COI sequence of 687 base pairs was obtained from the E. furinalis specimen, which was 99.80% similar to the E. furinalis sequences with which it was compared. This analysis of the COI marker thus confirmed the morphological identification of E. furinalis . The clusters observed in the Maximum Likelihood analysis showed a strongly supported clade with 99% bootstrap clustering E. furinalis specimens from Maranhão (present study), Guyana, Suriname and French Guiana; the other species grouped in separate and well-supported clades ( Fig. 3 View Figure 3 ).

This is the first record of E. furinalis specimen in the Brazilian state of Maranhão, in the municipality of Cândido Mendes ( Fig. 4 View Figure 4 ) extends the known distribution of the species by 676.1 km to the west and north from the nearest known locality at the RPPN Serra das Almas, in the Brazilian state of Ceará (05°05’ South, 40°50’ West) ( Silva et al. 2015)

The E. furinalis specimen was collected in an area of dense forest in the municipality of Cândido Mendes (1°27’21” South, 45°43’32” West) on April 26th 2017 by Costa, CLS, Ventura, MCS and Mendes, SB. GoogleMaps This municipality is within the Amazon domain, and its vegetation is dominated by dense rainforest ( Brasil c2015). The specimen was collected with a mist-net, 3x 12 m, with a 25 mm mesh. The specimen was weighed using a Pesola balance and the basic external and cranial measurements were using a manual calliper Carbografite (0-150 mm, precision 0,02mm). The specimen was classified as a young adult, based on the ossification of the phalangeal epiphyses (Anthony 1988). The identification and morphological and craniometric measurements were obtained followed by Taddei et al. (1998), Barquez et al. (1999), Van Cakenberghe et al. (2002) Díaz et al. (2011) and Reis et al. (2011, 2013, 2017).
