“…However, molecular evidence indicates an even closer relationship between the R. acrolopha group and certain species of the R. veraguensis group, specifically R. chavin, R. manu, R. nesiotes, and R. yanachaga (Pramuk, 2006;Chaparro et al, 2007;Pramuk et al, 2008;Van Bocxlaer et al, 2010;Pyron and Wiens, 2011;Peloso et al, 2012;Moravec et al, 2014). Furthermore, the results of those analyses of DNA sequences are consistent with the distribution of several putative morphological synapomorphies, including: (1) occurrence of few, large, unpigmented eggs in the R. acrolopha group and R. chavin, R. justinianoi, R. manu, R. multiverrucosa, R. nesiotes, and R. yanachaga of the R. veraguensis group (Duellman and Toft, 1979;Lehr et al, 2001Lehr et al, , 2005Lehr et al, , 2007Chaparro et al, 2007); (2) m. levator mandibulae externus undivided with trigeminal nerve passing medial (deep) to the muscle in R. paraguas (reported herein) and all other species of the R. acrolopha group (TG, personal observation) and at least R. manu (Chaparro et al, 2007) and R. quechua (TG, personal observation) of the R. veraguensis group; and (3) absence of the m. adductor longus in the R. acrolopha group (Trueb, 1971; TG, personal observation) and R. manu (Chaparro et al, 2007). In contrast, species of the R. margaritifera group possess many small, pigmented eggs, a divided m. levator mandibulae externus with V 3 passing between the two slips, and usually (for an exception, see Vélez-Rodríguez and Ruiz-Carranza, 2002) the m. adductor longus (Trueb, 1971;Frost et al, 2006).…”

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.

“…nov., and R. rostrata). Lehr et al [8] noticed vitelline-rich eggs (266-286, n = 2) in oviducts of R. chavin and suspected direct development; the eggs had a diameter of 1.8 and 3.1 mm (n = 10), respectively. This is supported by the lack of running or temporary waters where R. chavin was found both at the type locality and in the Cordillera de Carpish.…”

“…nov. can be distinguished as follows: Rhinella moralesi sp. nov. and R. chavin (Figure 3A,B) share a stout body with relatively short extremities and short digits, large glands on the dorsum and a lateral row of enlarged, elevated glands, males with nuptial pads on the first and second finger and absence of vocal slits [8].

“…The 29 Peruvian species of Rhinella are assigned to five species groups: festae Group, margaritifera Group, marina Group, spinulosa Group, and veraguensis Group [3][4][5][6]. The festae species Group was recognized by Moravec et al [6] based on molecular characters and included eight species [6,7]: R. chavin (Lehr, Köhler and Ponce, 2001) [8]; R. festae (Peracca, 1904) [9]; R. lilyrodriguezae Cusi, Moravec, Lehr and Gvoždík, 2017 [7]; R. macrorhina (Trueb, 1971) [10], R. manu Chaparro, Pramuk and Gluesenkamp, 2007 [5], R. nesiotes (Duellman and Toft, 1979) [11], R. rostrata (Noble, 1920) [12], and R. yanachaga Lehr, Pramuk, Hedges and Córdova, 2007 [13]. Pereyra et al [3] revised the festae species Group, provided a diagnosis for its members, and recognized anatomical and morphological synapomorphies.…”

We describe a new species of Rhinella from montane forests between 1788 and 2305 m a.s.l. in the Departamentos Amazonas and San Martín, Peru. We tentatively assign the new species to the Rhinella festae species Group based on morphological similarities with its other 19 members. It is characterised by large size (maximum SVL 91.6 mm in females), a pointed and protruding snout that is posteroventrally inclined, absence of a visible tympanic annulus and tympanic membrane, long parotoid glands in contact with upper eyelid, presence of a dorsolateral row of enlarged tubercles, outer dorsolateral tarsus surface with a subconical ridge of fused tubercles, and absence of subgular vocal sac and vocal slits in males. One specimen from Departamento Amazonas tested positive for Batrachochytrium dendrobatidis.

“…THE GENUS Rhinella is a group of Neotropical bufonids with 86 species distributed from southern Texas (USA) to southern South America. Among these, the 16 taxa tentatively assigned to the R. veraguensis group (sensu Duellman and Schulte, 1992) are distributed mostly along the Andes from Peru to northwestern Argentina (with the exception of R. chrysophora, endemic to Honduras) and occur across a gradient of 1280-3070 m in altitude (Duellman and Toft, 1979;Duellman and Schulte, 1992;Lehr et al, 2001;Pramuk and Lehr, 2005). However, only five species of this assemblage (R. amboroensis, R. chavin, R. manu, R. nesiotes, and R. veraguensis), have been included in phylogenetic analyses and the group remains paraphyletic in all hypotheses (Pramuk, 2006;Chaparro et al, 2007;van Bocxlaer et al, 2010;Pyron and Wiens, 2011).…”

The Stream Tadpoles ofRhinella rumbolli(Anura: Bufonidae)

2014

View full text Add to dashboard Cite

The Rhinella veraguensis group is likely a paraphyletic assemblage that contains 16 species of Andean toads. To date, descriptions are available for larval stages of only three species, all of which possess a distinct sucker in the abdominal region. In this study, we describe the tadpoles of Rhinella rumbolli, a medium-sized Salta Toad typical of forest streams in northwestern Argentina. Thirty-three larvae (Gosner Stages 32-36) were processed for studies of the external morphology, buccal cavity, and musculoskeletal system. These larvae show a mosaic of features, some typical of the genus and some others unique to the R. veraguensis group. Several character states are specific to R. rumbolli, namely the lack of an abdominal sucker, 2-4 lingual papillae, and the absence of adrostral cartilages. Some traits are frequent in other stream tadpoles such as the muscular tail, large oral disc with complete labial rows, and the wide and robust anterior neurocranium. Bufonid tadpoles exhibit an extraordinary variation in ecology, such as preferred microhabitat, and the diversity within the family is exemplified within the genus Rhinella. Further comparative morphological and developmental studies, framed in the context of phylogenetic hypotheses, are needed in order to explore the pattern variation in different clades and to discuss character evolution and form-function relationships.
