Abstract: 

We  describe  a  new  species  of Vitreorana  from  the  Atlantic  Forest  of  southern  Bahia  state,  in  north-eastern  Brazil. Vitreorana  assuh sp.  nov.  is  by  far  the  largest  species  of  the  genus  (snout-to-vent  length  [SVL]  =  30.9  mm  and  34.1 mm in one male and female, respectively; maximum SVL recorded for all other species = 28.0 mm). The new species is morphologically most similar to V. franciscana, from the Cerrado biome in Brazil. Besides its large size, the new species has, among other diagnostic characters, the presence of vomerine teeth and the occurrence of enameled iridophores in the pericardium, hepatic and urinary bladder peritonea. Furthermore, we describe and compare the complete mineralized skeleton of the new species and V. uranoscopa, and describe and discuss the variation of integumentary spicules in all species of the genus and their relevance to Vitreorana systematics.
