Hypsiboas punctatus (Schneider 1799) (Figure 1) is a hylid frog that belongs to the H.  punctatus group  (sensu  Faivovich  et  al.  2005).  The coloration of this species is highly variable, with a predominantly  green  background  with  little  red spots  scattered  on  the  dorsum  (nocturnal coloration). The red spots become diffuse during daytime,  restricted  to  tiny  red-brown  flecks,  or these are absent (Duellman 1974). According to Frost  (2004)  and  AmphibiaWeb  (2006),  the species occurs in the Amazon Basin of Ecuador, Peru,  Bolivia  and  Brazil,  Upper  Orinoco  Basin, Central Brazil, Chaco of Paraguay and Argentina, Guyana,  French  Guiana,  Suriname,  Northern Colombia, Trinidad Island (Trinidad and Tobago) and  Venezuela.  Bernarde  (1998)  extended  the distribution  to  Southern  Brazil  (municipality  of Diamante  do  Norte,  Paraná  state),  but  there  are still some gaps in the species’ distribution, mainly associated to the Brazilian Atlantic Forest. In this biome  a  very  similar  species  occurs,  Hypsiboas atlanticus  (Caramaschi  and  Velosa  1996).  This species differs from H. punctatus by a larger head and  shorter  snout,  two  short  and  contiguous groups of vomerian teeth (vomerian teeth groups elongated and separated in H. punctatus), and an approximately circular choanae (choanae elliptical and elongated in H. punctatus) (Caramaschi and Velosa 1996). Herein, we report for the first time the presence of H. punctatus in northeastern and southeastern Brazil, in the states of Pernambuco and São Paulo, respectively.  Specimens  of  H.  punctatus  from  Pernambuco state  were  collected  in  the  municipality  of Igarassu  (Refúgio  Ecológico  Charles  Darwin, 07º48' 37' '  – 07º49' 2' ' S, 34º27' 25" – 34º56' 52" W) by E. Maranhão, in 1994; those from São Paulo state  were  collected  in  the  municipality  of Teodoro  Sampaio  (Parque  Estadual  Morro  do Diabo,  22°37' 00,5"S,  52°10' 10,4"W)  by  T.  S. Vasconcelos  and  T.  G.  dos  Santos,  in  January 2006.  In  this  latter  locality,  calling  males  were found on the vegetation (predominantly composed by Cyperaceae) at the edge of an artificial dam, and  in  flooded  areas  at  the  margins  of  the Paranapanema  River  (predominantly  composed by  Thyphaceae:  Thypha  sp.,  Pontederiaceae: Eichornia  sp.).  Voucher  specimens  were deposited  in  the  Coleção  Célio  F.  B.  Haddad (CFBH 12014-12020), UNESP, Rio Claro, and in the  Departamento  de  Zoologia  e  Botânica (DZSJRP 9888-9891), UNESP, São José do Rio Preto, both in São Paulo state, Brazil.￿  Figure  1.

According  to  Duellman  (1999),  H.  punctatus  is distributed  across  three  biogeographical  South American  regions:  1)  Caribbean  lowlands,  that includes from tropical dry forest to tropical thorn woodland and desert scrub with tropical evergreen and  semideciduous  gallery  forest,  ranging  from the vicinity of Cartagena, Colombia, to the Golfo de  Paria,  northeastern  Venezuela;  2)  Amazon Basin-Guiana  lowlands,  predominantly  covered by  humid  tropical  rainforest  and  including  the lowland  catchment  area  of  the  Amazonas  River and its many tributaries that make up the Amazon        62 Check List 2006: 2(2) ISSN: 1809-127X  NOTES ON GEOGRAPHIC DISTRIBUTION Basin,  which  is  continuous  with  the  Guianan lowlands in northeastern South America, and 3) Cerrado-Caatinga-Chaco complex, predominantly covered by  savanna  and open forest formations, encompassing  an  area  in  the  interior  of  the continent  from  northeastern  Brazil  to  northern Argentina.  In  addition  to  what  was  reported  by Bernarde (1998), the present study confirms that H. punctatus is also found in the Atlantic Forest domain  (Mesophitic  Semideciduous  Forest  sub-domain). The  records  here  reported  extend  the  known geographical  distribution  of  H.  punctatus  to  the northeastern region of Brazil (Pernambuco State), and fill a distribution gap in southeastern Brazil (São Paulo state). Such an expressive enlargement of  the  geographical  distribution  of  the  species reflects  the  lack  of  herpetological  surveys  in Brazil, even in regions well studied, such as the state of São Paulo.
