Albinism is a genetic variation resulting from a combination of homozygosis in recessive alleles, leading to disturbance of the melanin system (Carden et al., 1998). Albino individuals tend to have less success in their protection and communication with other individuals of the same species due to their different colour (Sazima and Pombal, 1986; Sazima and Di- Bernardo, 1991). Occurrences of albinism are known for a variety of vertebrates throughout the world (e.g., Arribas, 1986; Barg and Canepuccia, 2003; Brassaloti and Bertoluci, 2009; Escoriza, 2012; Johnston, 2006; McCreary, 2008). In anurans, albinism was recorded worldwide in larvae, juveniles and adults (Martinuzzi et al., 2016). In Brazil, records of albino tadpoles . are known for at least three species: Leptodactylus latrans (Rodrigues and Oliveira Filho, 2004), Rhinella ornata (Brassaloti and Bertoluci, 2009), and Boana albomarginata (Salles et al., 2013), while adult and juvenile albino anurans are documented for only one species: L. troglodytes (Santos and Silva, 2010). During a fieldwork on November 24 th , 2017 at Área de Proteção Ambiental (APA) Mestre Álvaro, municipality of Serra, state of Espírito Santo, southeastern Brazil (20.1673° S 40.1804° W, Datum = WGS84, maximum elevation 800 m a.s.l.), we recorded an albino juvenile (CRC: 40 mm) of Rhinella crucifer (Figure 1) in a pitfall trap at 45 m a.s.l. The individual was collected under license number Sisbio 57085-2 and SEMMA 18.731/2017 and housed at the amphibian collection of the Museu de Biologia Professor Mello Leitão (MBML) of the Instituto Nacional da Mata Atlântica (INMA), in the municipality of Santa Teresa, state of Espírito Santo, Brazil (albino individual voucher MBML 11095 and regular individual voucher MBML 11096). The individual was identified as Rhinella crucifer by its triangular to oval paratoid glands that protrude over the body edge dorsally and short and rounded snout (see Baldissera et al., 2004). Albinism in the genus Rhinella was identified in tadpoles of R. ornata (Brassaloti and Bertoluci, 2009) and R. arenarum (Barg and Canepuccia, 2003), but never before in a Rhinella crucifer adult. Although R. crucifer is an abundant species in the APA Mestre Álvaro (manuscript in prep), this is the first anuran specimen with albinism recorded in our study. Acknowledgments.
