Danny Ordoñez, Marcio Martínez leg., 1 adult male, UVS-V-02059 ( Fig. 3 View Figure 3 ) • Río Plátano Biosphere Reserve, El Limón ; 15°22ʹ39ʺN, 085°11ʹ45ʺW; 310 m elev.; 18 Sept. 2018; Hefer Daniel Ávila-Palma, Danny Ordoñez, Marcio Martínez leg.; 1 adult male. GoogleMaps

Both individuals were captured between 18:25 and 18:40 h, while the moon phase was first quarter with illu- mination between 42.9 and 62.1% of moonlight. There was drizzling rain when these bats were captured. Neither individual presented evidence of reproductive activity. We recorded ectoparasites only on the individual from El Limón, which was captured in an area within the very humid subtropical forest in which platanillos ( Heliconia sp.; Fig. 2 View Figure 2 ) were abundant. The specimen from Wuarska was captured in a ravine emerging from a cave (approxi- mately 15 m above) surrounded by forest and ending in the Río Plátano. This specimen vocalized while it was being taken out from the mist net and attracted other bats (some individuals of C. perspicillata were caught during these calls). These distress calls are emitted by bats under the physical stress of being caught by a predator and, similarly, when constrained in a trap or by an experimenter, and the attraction of other bats may help to escape by distracting or frightening the predator ( Russ et al. 2004; Eckenweber and Knörnschild 2016).

Identification. Both individuals have spatulated upper inner incisors (pointed in M. bennettii ), dark brown dorsal pelage (brown-reddish in M. bennettii ), and white

wingtips (dark in M. bennettii ). The collected specimen presented a narrow talonid on the third lower molar (larger in M. bennettii ), V-shaped posterior edge of the palate (U-shaped in M. bennettii ), mandible length longer than 16.7 mm (shorter than 16.7 mm in M. bennettii ), and second lower premolar (p4) enlarged with a posterior cingulum (reduced posterior cingulum in M. bennettii ) ( Simmons and Voss 1998; but see Gregorin et al. 2008).

External measurements (in mm) are as follows (for UVS-V-02059 and the released individual, respectively): FA = 54.46, 55.75; Tib = 23.06, 23.30; E = 29.40, 29.48; EW = 16.30, 17.90; Th = 5.25, 6.45; LN = 19.71, 20.05; Tr = 9.25, 10.03; TrW = 3.21, 3.21; Ca = 18.11, 18.13; T = 16.52, 18.05; BH = 64.25, 69.22; HF = 12.95, 13.3; 3mt = 46.09, 46.31; 3ph = 16.32, 16.55; 2ph = 25.86, 26.33; 1ph = 18.35, 20.07; body mass = 23.0, 23.0 g. For the skull of the specimen UVS-V-02059, we obtained the following data: CBL = 25.91; ZB = 13.24; HB = 8.32; MB = 10.92; WUM = 9.75; CM 3 = 7.27; LR = 5.39; LP = 10.34; LUC = 3.86; CC = 7.34; HM = 2.22; LLC = 4.25; LM = 17.43; CM 3 = 9.81; HC1 = 7.02; HC2 = 6.27; HC3 = 6.74.
