The genus Hylodes Fitzinger, 1826 (Hylodidae),
comprising small, diurnal rheophilic frogs, is endemic to
eastern Brazil and associated to the Atlantic Forest biome
(including areas of Atlantic Forest-Cerrado ecotones)
(Laia and Rocha 2012). Most of the known species in
this genus occur within an area that encompasses the
southeastern portion of São Paulo State, southern Minas
Gerais State and the western half of Rio de Janeiro
State (see Laia and Rocha 2012). One of those species
is Hylodes phyllodes Heyer & Cocroft, 1986, originally
described from the Estação Biológica de Boracéia,
municipality of Salesópolis, São Paulo State (Heyer and
Cocroft, 1986). Subsequent records have extended its
distribution both to the east and to the west, including
some continental islands (Hartmann, Hartmann, and
Haddad, 2006; Canedo and Pombal 2007; Carvalhoe-Silva et al. 2008; Condez, Sawaya and Dixo, 2009;
Cicchi et al. 2009; Gründler et al., 2012). One insular
record reported by Rocha et al. (1997), however, was
based on a population that was later described as a
distinct species (Hylodes fredi) by Canedo and Pombal
(2007). Herein, we provide a new locality record for this
species, expanding its known distribution.
The Santuário de Vida Silvestre da Serra da Concórdia
(22° 22’ 18” S, 43° 47’ 23” W) is a private reserve situated
in the municipalities of Barra do Piraí and Valença, in

the State of Rio de Janeiro. During a herpetological
inventory carried out in that area we collected five
individuals of H. phyllodes (Fig. 1) between 12 and 14
April 2005 (under collection permit 055/2005 issued
by RAN/IBAMA). The specimens (three adult males,
one subadult male, one adult female), were all found
perched on rocks in lotic forest streams at 650-750 m
elevation. They are currently deposited at the amphibian
collection of Museu Nacional, Rio de Janeiro (MNRJ
41675-79).
The present report represents the easternmost and
northernmost record for H. phyllodes, extending its
distribution about 75 km to the northeast of the previous
easternmost locality reported for the species (Reserva
Rio das Pedras, Mangaratiba; Carvalho-e-Silva et al.
2008) (Fig. 2). Together with the record from the Parque
Estadual do Jurupará, in São Paulo State (Condez,
Sawaya and Dixo, 2009), it also represents the most
inland record for the species, at ca. 60 km from the
coast. Furthermore, as can be seen in Fig. 2, all previous
records of H. phyllodes came from sites located at the
