A new species of Chiroderma (Chiroptera, Phyllostomidae) from Northeastern Brazil

Abstract

A new species of Chiroderma Peters, 1860 (Chiroptera, Phyllostomidae) from the State of Piauí in Northeastern Brazil is described based on mensural analysis, morphological data and geographical distribution. It is most similar morphologically to C. doriae Thomas, 1891 but differentiated by a smaller body size and by differences in cranial traits. In comparison to other members of the genus, the new species can be distinguished by a combination of characters, including size of the body, conspicuousness of facial and median dorsal stripes, ear length, and variation in cranial and dentition traits.

The mammalian faunas endemic to the Cerrado and the Caatinga

“…Chiroderma vizottoi is endemic to the Caatinga, and has been recorded in the Brazilian states of Ceará and Piauí (Gregorin et al 2008, Taddei and Lim 2010, Silva et al 2015). …”

New Genus and Species of Nectar-Feeding Bat from the Atlantic Forest of Southeastern Brazil (Chiroptera: Phyllostomidae: Glossophaginae)

“…Description: Body size small (forearm 29-32 mm; tables 1-2) for a Glossophaginae and for bats in general; muzzle elongated, but shorter than braincase; mandibular prognathism evident; spear of noseleaf nearly triangular (3 mm wide × 3.38 mm tall in the fluid paratype) with no central rib; internarial region with narrow, unbeaded ridge along midsagittal line; horseshoe of noseleaf continuous with upper lip with no ridges or other structures separating it from lip; lateral edges of horseshoe confluent with face inferiorly, but with superior edge free; dorsal snout with pair of well-developed padlike papillae separated from each other and located just behind noseleaf; two columns of vibrissae present at each side of snout, lateral to noseleaf, the more anterior with its two vibrissae standing entirely on the padlike papilla, and the more posterior with three of its four vibrissae standing on this pad (the lowest vibrissa stands on its own smaller pad); anterior half of the upper lip, at each side of mouth, also ornamented with well-developed vibrissae, five of which are nearly evenly distributed in an irregular line parallel to lip, beginning close to posterior border of the large padlike papilla described above, and one located just above the more posterior of these vibrissae; one genal vibrissa present halfway between the corner of the mouth and the base of the ear notch; chin with deep central cleft and with a pair of narrow, scalloped dermal pads, one on each side of the cleft; two interramal vibrissae located posterior to the chin cleft; chin skin adjacent to the cleft, along each side of the mandible, ornamented with five well-developed vibrissae arranged, from anterior to posterior region, in a 1-2-1-1 scheme (additional, smaller vibrissae also present); ears small, with rounded distal tip, strongly convex inner margin, and outer margin nearly straight; tragus about one third the length of the pinna, spatulate in form, noticeably thicker medially, thinner and translucent laterally, bearing a basal expansion with a lobule on its upper margin that is folded posteriorly; forearm with basal two-thirds covered with fur on both the dorsal and ventral surfaces; metacarpal and proximal phalange of thumb nearly equal in length; metacar- (Soriano et al, 2005), French Guiana (Simmons and Voss, 1998), Pará, in northern Brazil (USNM 239520 -holotype, from Swanepoel and Genoways, 1979;MPEG 1251), and Bahia, in northeastern Brazil (Taddei and Pedro, 1993).…”

Structure and natural history of an assemblage of bats from a xerophytic area in the Caatinga of northeastern Brazil

“…With the intensification of research, these numbers have grown for bats and other taxa, with new occurrence records and undescribed species emerging (Gregorin and Ditchfield 2005;Gregorin et al 2006;Taddei and Lim 2010;Moratelli et al 2011;Novaes et al 2013a). Although several studies have focused on Caatinga bats (e.g.…”
