A new species of beaked toad, Rhinella, is described from Itacaré (14°17'S, 38°60'W; 13 m altitude), State of Bahia, Northeastern Brazil. Rhinella skuki sp. nov. is related to R. boulengeri and distinguished by the size small (SVL 26.2 mm in male); head longer than wide; snout, viewed from above, long, narrow, spatulate, with lateral borders parallel and rounded tip; in profile, long, strongly acute; parotoid glands large, rounded; tympanum concealed; dorsum rugose, with rounded tubercles uniformly distributed; vocal sac and vocal slits absent; fingers slender, not webbed nor ridged; first finger hypertrophied, with a rounded nuptial pad on the inner surface; toes slender, slightly fringed; webbing absent; ground color of dorsal surfaces dark brownish gray with an interorbital bar and dorsolateral blotches clear brownish gray, leaving an apparent pattern of arrows on dorsum; venter and ventral surfaces of arms and thighs cream with diffuse gray stains and dots; gular region and chest dark brownish gray

“…) The mode of amplexus in frogs has been accorded systematic significance by many workers (e.g.. Noble, 1931;Laurent, 1967;Lynch, 1973;Nussbaum, 1980;Duellman and Trueb, 1986). All so-called "primitive" frogs exhibit inguinal amplexus, while most of the so-called "advanced" frogs exhibit axillary amplexus.…”

“…All so-called "primitive" frogs exhibit inguinal amplexus, while most of the so-called "advanced" frogs exhibit axillary amplexus. Consequently, axillary amplexus is considered the derived mode of amplexus among frogs (Lynch, 1973;Duellman and Trueb, 1986). In this paper we report the discovery of inguinal amplexus in a neobatrachian frog.…”

“…The possibilities are: (1) inguinal amplexus is the ancestral condition for Bufonidae, in which case, barring parallelism, the four species known to have inguinal amplexus are outside of a clade formed by the rest of the bufonids; or, (2) inguinal amplexus is derived within Bufonidae, in which case, again NOTES barring parallelism, it may be a synapomorphy providing evidence of a close relationship among certain species. According to Lynch (1973) and Duellman and Trueb (1986), Bufonidae is a monophyletic taxon and part of a larger clade whose most recent common ancestor is inferred to have exhibited axillary amplexus. Thus, inguinal amplexus in bufonids appears to be secondarily derived.…”

“…The authors did not challenge the monophyly of Rhamphophryne, which is supported by limited morphology (see Frost et al, 2006:217) and has been upheld in phylogenetic analyses of DNA sequences (Van Bocxlaer et al, 2010;Pyron and Wiens, 2011;see ''Phylogenetic relationships,'' below). Consequently, we follow Chaparro et al (2007) in describing this toad as a new species of Rhinella and, to facilitate comparisons, refer to the species of the former Rhamphophryne-including R. acrolopha (Trueb, 1971), R. festae (Peracca, 1904), R. lindae (Rivero and Castaño, 1990), R. macrorhina (Trueb, 1971), R. nicefori (Cochran and Goin, 1970), R. rostrata (Noble, 1920), R. ruizi (Grant, 2000(Grant, ''1999, R. tenrec (Lynch and Renjifo, 1990), and R. truebae (Lynch and Renjifo, 1990)-as the Rhinella acrolopha group.…”

We describe a new species of the Rhinella acrolopha group (previously Rhamphophryne) from mid-elevations (1800-2500 m) of the Cordillera Occidental of Colombia. It is found exclusively in cloud forest habitats and is not associated with streams or other bodies of water. The species is characterized by possessing eight presacral vertebrae, fusion of the sacrum and urostyle, and nuptial excrescences in adult males, and in lacking conspicuous cranial ornamentation and vocal slits. The most striking characteristic of this species is its middle ear, which lacks a tympanic membrane and annulus but possesses a short stapes that articulates with the palatoquadrate and squamosal in a manner similar to the middle ear of many salamanders. A population of this species in the Serranía de los Paraguas seems to be stable despite drastic declines in many sympatric species.RESUMEN: Describimos una nueva especie perteneciente al grupo Rhinella acrolopha (anteriormente Rhamphophryne) de elevaciones medias (1800-2500 m) en la Cordillera Occidental de Colombia. La nueva especie ha sido encontrada exclusivamente en hábitat de bosques nublados y no está asociada con quebradas u otros cuerpos de agua. La especie se caracteriza por poseer ocho vértebras presacrales, fusión del sacro y el uróstilo, excrecencias nupciales en machos adultos, ausencia de crestas craneales agrandadas y ausencia de hendiduras vocales en machos adultos. La característica más destacada de la nueva especie es su oído medio, el cual carece de membrana timpánica y anillo timpánico pero presenta un estribo reducido que se articula con el palatocuadrado y el escamoso, semejante a lo que se encuentra en salamandras. Una población de esta especie en la Serranía de los Paraguas al parecer se mantiene estable, a pesar de la disminución drástica de poblaciones de especies simpátricas.
