The genus Trachycephalus is found in lowlands of Mexico, Central, and South America east of the Andes, south to north Argentina and eastern Brazil (Frost, 2016). In Brazil, Trachycephalus Tschudi, 1838 is represented by 13 species: Trachycephalus atlas Bokermann, 1966; T. cunauaru Gordo, Toledo, Suárez, Kawashita- Ribeiro, Ávila, Morais & Nunes, 2013; T. coriaceus (Peters, 1867); T. dibernardoi Kwet & Solé, 2008; T. hadroceps (Duellman & Hoogmoed, 1992); T. helioi Nunes, Suárez, Gordo & Pombal, 2013; T. imitatrix (Miranda-Ribeiro, 1926); T. lepidus (Pombal, Haddad & Cruz, 2003); T. mambaiensis Cintra, Silva, Silva_Jr, Garcia &Zaher, 2009; T. nigromaculatus Tschudi, 1838; T. resinifictrix (Goeldi, 1907); T. typhonius (Linnaeus, 1758) and T. mesophaeus (Hensel, 1867) (according to Frost, 2016). The Porto Alegre Golden-eyed tree frog Trachycephalus mesophaeus was described from Porto Alegre, Rio Grande do Sul by Hensel (1867) and occurs in the Atlantic forests of the states of Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Minas Gerais, Rio de Janeiro, Espiríto Santo, Bahia, Pernambuco, and Alagoas (Haddad et al., 2013) (Table 1). This arboreal anuran is endemic to Atlantic forest where it occurs at the forest edge, living on vegetation near water bodies. It is a species with explosive breeding, using temporary and permanent ponds (Carvalho-e-Silva and Garcia, 2004; Haddad et al., 2013). Here, we provide the first record for this species from the state of Sergipe, Northeastern Herpetology Notes, volume 9: 255-260 (2016) (published online on 31 October 2016) New records of Trachycephalus mesophaeus (Hensel, 1867) (Anura: Hylidae) from Atlantic Forest in Sergipe state, Brazil Daniel Oliveira Santana 1, *, Rony Peterson Santos Almeida 2,4 , Francis Luiz Santos Caldas 1 , Eduardo José dos Reis Dias 4 and Renato Gomes Faria 3 1 Programa de Pós Graduação em Ciências Biológicas (Zoologia), Universidade Federal da Paraíba, Cidade Universitária, CEP 58059-900, João Pessoa, PB Brasil; 2 Programa de Capacitação Institucional, Museu Paraense Emílio Goeldi, Coordenação de Ciências da Terra e Ecologia.
