No. of bitstreams: 0 Previous issue date: 2010-01-20 We describe adult morphology, advertisement call and some natural history traits of a new species of toad from the Pantanal, western Brazil. Rhinella paraguayensis sp. nov. belongs to the Rhinella margaritifera group, and is characterized by medium size, snout rounded in dorsal view, with a vertical apical ridge, supraorbital crests weakly developed, parietal crest not well developed, postorbital crest prominent, presence of a dorsolateral line of tubercles, tympanum evident, bony protrusions at angle of jaws, absence of vertebral apophyses and of projections on upper eyelids, and parotoid glands small. The new species is distinguished from other species of the group by geographic distribution and by the use of floating mats of vegetation as reproductive site. Copyright © 2010 Magnolia Press.

Accepted by M. Vences: 29 Apr. 2009; published: 22 May 2009, We resurrect Rhinella leptoscelis (Anura: Bufonidae) from the synonymy of R. veraguensis and redescribe it on the basis of the holotype, and recently collected specimens from Peru and Bolivia. Rhinella leptoscelis is well distinguished from all other species of the R. veraguensis group by its flat head with well developed orbitotympanic and postorbital crests, distinct tympanum, large parotoid glands, spiny tubercles on dorsal surfaces, long and slender extremities, dorsolateral row of conical, enlarged and elevated tubercles, webbing absent on fingers, basal and serrated webbing between toes, and first finger longer than second. This species is known from the humid forests of the Amazonian versant of the Andes from central Bolivia to southern Peru., This work was partially funded by projects REN/GLO 2001-1046 and CGL2005-03156 of the Spanish Ministry of Science and Innovation (I. De la Riva, Principal Investigator).
