Gregorin R. & Rossi R. V. 2005. — Glyphonycteris daviesi (Hill, 1964), a rare CentralAmerican and Amazonian bat recorded for Eastern Brazilian Atlantic Forest (Chiroptera,Phyllostomidae). Mammalia 69 (3-4) : 427-430.

Thomas (1896) described Glyphonycteris underthe type species G. sylvestris, and as currentlydefined the genus comprises the speciesG. behnii, G. daviesi and G. sylvestris (Koopman,1994). However, the validity of the formerspecies has been questioned by Simmons (1996)and Simmons & Voss (1998), who considered itas a supposed senior synonym of G. sylvestris. Anemended diagnose of the genus can be found inSimmons & Voss (1998).Glyphonycteris daviesi is a rare species with hand-ful specimens in museums. Charles-Dominiqueet al. (2001) considered it extremely rare inFrench Guiana, since less than six specimens wererecorded among c. 15,000 bat captures. Thespecies occurs on lowlands of Central Americaand northern South America, from Hondurassouthward to the states of Rondônia and Pará in

Brazil and the north of Bolivia (Fig. 1) (Brosset& Charles-Dominique 1990; Pine et al. 1996;Anderson 1997; Simmons & Voss 1998). Nosubspecies is currently recognized (Koopman1994).During a recent bat inventory at the Serra doTeimoso farm (15°09’25”S, 39°32’15”W),municipality of Jussari, state of Bahia, easternBrazil (Fig. 1), we recorded two adult femalespecimens identifiable as G. daviesi. The expedi-tion was carried out in the period of 5th to 16thJuly of 2001, during the dry season. A scarpedrelief covered with a peculiar rainforest thatshares several flora elements with eastern Amazonforest and has high level of endemism (Mori et al.1983) characterize the site. Our specimens werecaptured at an estimated altitude of 500 m insidea primary selected logged forest using mist nets at

ground level. These conditions are similar tothose reported by Pine et al. (1996) for most ofthe captured specimens of G. daviesi until thattime, and by the subsequent authors as well.Specimens were preserved in alcohol with theskull and tissue extracted. They are housed at theMuseu de Zoologia da Universidade de SãoPaulo under the numbers MZUSP 29756 and29760.Most of morphological characters present in ourspecimens agree with those of the holotype (Hill1964) and with an Amazonian adult male speci-

men in hand (MZUSP 28532). Our specimensalso conform in size to the holotype and otherfemale specimens reported by Pine et al. (1996)and Simmons & Voss (1998). The set of charac-ters that warrant the specimens identification are:1) large, pointed and not joined pinnae on theforehead, with concavity on the posterior bordernear tip; 2) large size (see measurements below);3) latero-dorsal enlargement of the rostrum;4) two high and chisel-like upper incisors;5) upper canines with the low main cusp andmassive base; 6) great enlargement of upper pre-

Localities are provided as follow: Bolivia (Anderson 1997), FrenchGuiana (Brosset & Charles-Dominique 1990; Simmons & Voss 1998), and remaining localities in Albuja (1999), Bernard & Fenton(2002), Clarke & Racey (2003), Pine et al. (1996), Sampaio et al. (2003) and Solari et al. (1999). The type locality is “24 miles fromBartica, along the Potaro Road, British Guiana”. Our record locality is “Fazenda Serra do Teimoso, municipality of Jussari, state ofBahia, Brazil”. Sites of recorded specimens are sample localities where specimens have been captured and later released orescaped.

molars; 7) lack of emargination of the lingual cin-gula at the first and second molars; 8) metacarpalformula 4 < 3 < 5; and 9) trifid, tall, and scoop-like lower incisors. A noticeable depigmentationon the tip of the wing and the overlap of the pos-terior edge of the upper canine with the anteriorborder of the first premolar are two characterspresent in our specimens and in MZUSP 28532that have never been commented by previousauthors.Weights (in g) of the specimens MZUSP 29756and 29760 are respectively 24.0 and 25.0, andmeasurements (in mm) are: forearm length 56.2and 58.1; ear length 26.4 and 26.2; total breadthof ear 16.1 and 17.6; length of the tail 5.7 and6.5; 3rd metacarpa l 53.7 and 54.9; 4thmetacarpal 49.4 and 51.9; 5th metacarpal 54.2and 55.4; skull length (including the incisors)27.0 and 27.4; condylo-incisive length 24.9 and25.6; zygomatic breadth 14.0 and 13.9; inter-orbital breadth 5.7 and 6.1; braincase breadth10.5 and 10.7; mandible length (including inci-sors) 19.4 and 19.9; maxillary toothrow length(canine-3rd molar) 10.9 and 11.0; upper caninelength 2.5 and 2.4; breadth across upper canines4.9 and 5.1; breadth across second upper molar9.3 and 9.6. The specimen MZUSP 29760 pres-ents visib le, though reduced, nipples andMZUSP 29756 has no sign of these structures,indicating that the mating and lactation periodprobably occurred on warmer and wetter seasons.The present record extends the distribution ofG. daviesi about 1,700 km southeastward in Brazil(Fig. 1) and it corroborates the known pattern ofdistribution of some bat species (e.g., Peropteryxleucopterus, Glyphonycteris sylvestris, Mimon ben-nettii, Platyrrhinus recifinus, Neoplatymops mat-togrossensis, and Thyroptera tricolor), which occurin Amazon and northeastern Atlantic Forests,connected by the mesic islands of vegetationacross the caatinga and cerrado biomes.
