Herpetology Notes, volume 9: 285-286 (2016) (published online on 14 November 2016) New state record of Vitreorana baliomma Pontes, Caramaschi and Pombal Jr., 2014 (Anura: Centrolenidae) Clodoaldo Lopes de Assis1,*, Marco Antônio Peixoto1, Emanuel Teixeira da Silva2 and Renato Neves Feio1 The genus Vitreorana Guayasamin, Castroviejo- specimens (MZUFV 5437, 5438, 5439; 18.07 mm, Fisher, Trueb, Ayarzagüena, Rada, Vilà (2009) is 17.43 mm, 16.76 mm, respectively) that conform to the composed of ten species (Frost, 2016), commonly description of V. baliomma (Pontes et al., 2014) (Figure known as glassfrogs. Five species occur in the Atlantic 1). The specimens were collected by R. N. Feio and Forest of Brazil and Argentina: Vitreorana eurygnatha U. Caramaschi at Fazenda Limoeiro, municipality of (Lutz, 1925), Vitreorana parvula (Boulenger, 1895), Almenara (-16.0555°S, -40.8359°W; Datum WGS 84; Vitreorana uranoscopa (Muller, 1924), Vitreorana 620 m a.s.l.), Jequitinhonha River valley (Figure 2), on baliomma Pontes, Caramaschi and Pombal Jr., 2014, 13 to 16 January, 2004. and Vitreorana franciscana (Pontes et al., 2014; This record confirms the presence of Vitreorana Santana et al., 2015). Vitreorana baliomma is a small baliomma in the state of Minas Gerais, and extends the glassfrog (SVL 16.4–21.2 mm, N = 16) that occurs in distribution of the species about 129 km east from the ombrophilous formations in the Northeastern portion of nearest known locality at municipality of Itapebi, Bahia the Brazilian Atlantic Rainforest, in the municipalities (Pontes et al., 2014). The historic presence of continuous of Areia Branca, state of Sergipe, and Itamaraju (type forests (currently fragmented) in the Jequitinhonha locality) and Itapebi, state of Bahia (Gouveia et al., River valley can explain the occurrence of this species 2012; Pontes et al., 2014; Frost, 2016). It differs from in inner areas of the north of Minas Gerais. the other Vitreorana species of the Atlantic Forest by having a thin layer of iridophores covering the stomach and intestines; rudimentary nuptial excrescences formed by glands on the dorsomedial surface of finger I (in males), with some accessorial glands along its periphery; kidneys, urinary bladder, and testes lacking iridophores layer; and iris pattern flecked by lavender star-shape melanophores (Pontes et al., 2014). During a review of Vitreorana specimens housed at Coleção de Anfíbios of Museu de Zoologia João Moojen, Universidade Federal de Viçosa, Viçosa, Minas Gerais state, Brazil, we found a lot with three 1 Museu de Zoologia João Moojen, Departamento de Biologia Figure 2.
