New records for Glyphonycteris Thomas, 1896 (Chiroptera: Phyllostomidae) from Colombia

Abstract

Species of Glyphonycteris Thomas, 1896 are poorly known foliage gleaning insectivore bats that inhabit the lowland forests of Central and South America (Ochoa and Velazco 2008; Zortea et al. 2008a; b). These bats have been considered rare because there are few specimens deposited in collections, and they are seldom caught in mist nets (Clark and Racey 2003; Gregorin and Rossi 2005). Simmons and Voss (1998) revised taxa traditionally considered subgenera of Micronycteris (Micronycteris, Trinycteris, Neonycteris, Lampronycteris, and Glyphonycteris) and assigned full generic rank to Glyphonycteris based on characters including the absence of an interauricular band, the calcar shorter than hindfoot, the rostral and anteorbital regions of the skull inflated, the braincase with a dome-shaped form, the deep basisphenoid pits; the upper internal incisors with a chisel-shaped form, the canines small but slightly bigger than the incisors;, the upper third premolar (P3) molariform, upper fourth premolar (P4) with accessory cuspulids and the lower trilobed incisors. Three species of Glyphonycteris are currently recognized: G. behnii (Peters, 1865) distributed in the Bolivian and Brazilian savannah and the Peruvian Amazon (Zortea et al. 2008b); G. sylvestris (Thomas, 1896) distributed from the lowlands of Central America southward to northern South America, with additional isolated records from southeastern Brazil (Zortea et al. 2008a), and G. daviesi (Hill, 1964) distributed in Honduras, Costa Rica, Panama southward to northern South America and Bolivia (Williams and Genoways 2008). Glyphonycteris sylvestris is the smallest species in the genus (forearm length less than 44 mm, and skull length shorter than 22 mm) and has two pairs of upper premolars (William and Genoways 2008). According to Solari et al. (2013) there are three documented records within Colombia: Alberico et al. (2000) reported a specimen deposited in the

“…IDENTIFICATION: Glyphonycteris sylvestris can be distinguished from other congeneric species by its tricolored dorsal fur, smaller size (forearm <44 mm, greatest length of skull <22 mm), two pairs of upper incisors that are nearly the same length as the canines, outer upper incisors that are almost hidden by the canine cingula in occlusal view, and lower incisors that are similar in anteroposterior and transverse dimensions Lopez-Baucells et al, 2018). Descriptions and measurements of G. sylvestris were provided by Sanborn (1949a), Goodwin and Greenhall (1961), Swanepoel and Genoways (1979), Williams and Genoways (1980a), Simmons (1996), Simmons and Voss (1998), Lim et al (2005), and Morales-Martinez and Suarez- Castro (2014).

Genus Glyphonycteris Thomas, 1896 (Mammalia: Chiroptera) in Ecuador: first confirmed record of G. sylvestris Thomas, 1896 and a geographical review to G. daviesi (Hill, 1965) [with erratum]

“…The genus includes three species: Glyphonycteris behnii (W. Peters, 1985), G. daviesi (Hill, 1965), and G. sylvestris Thomas, 1896 (Williams and Genoways 2008). Only Glyphonycteris daviesi occurs in Ecuador (Tirira 2012), but it is also known from Honduras, Costa Rica, Panama, Venezuela, Trinidad Island, Guyana, Surinam, French Guiana, Brazil, Colombia, Peru, and Bolivia (Pine et al 1996;Williams and Genoways 2008;Morales-Martínez and Suárez-Castro 2014), where it has been recorded below 500 m above sea level (Linares 1998;Solari et al 1999;Ochoa and Velazco 2008;Williams and Genoways 2008). In South America, G. daviesi has been traditionally recorded east of the Andes (Koopman 1978(Koopman , 1993Simmons 2005;Williams and Genoways 2008), with the exception of one record from Centro Científico Río Palenque (USNM 528475), Los Ríos province, Ecuador (Pine et al 1996).…”
