Julianus new genus

Juliana . Type species: Hyla uruguaya Schmidt.

Definition. Small frogs with slightly truncate discs on fingers and toes, webbing reduced between fingers and absent between Fingers I and II ( Fig. 10 C); venter immaculate; eggs deposited in ponds.

Content. Two species: Julianus pinimus* (Bokermann & Sazima) and J. uruguayus (Schmidt) , new combinations.

Distribution. Minas Gerais, Brazil, and extreme southern Brazil, Uruguay, and northern Corrientes, Argentina.

Etymology. The generic name is a patronym for Julian Faivovich in recognition of his many contributions to our knowledge of South American frogs. The gender is masculine.

Remarks. In our phylogenetic tree ( Fig. 4 ), Julianus uruguayus is the strongly supported (97%) long branch sister taxon of Scinax . Hyla pinima of Bokermann and Sazima (1973) has been associated with J. uruguayus because of characteristics of the larval oral disc ( Kolenc et al. 2003). Based on the interpretation of data by Kolenc et al (2003) and Faivovich et al. (2005), we place H. pinima in the genus Julianus .
