Abstract and Figures

Teratohyla sornozai fue recientemente descrita [1] sobre la base de especímenes colectados en tres localidades en las provincias de Esmeraldas, Imbabura y Pichincha, noroccidente del Ecuador. En la descripción original [1], T sornozai se diferenció de Rulyrana orejuela [2] por la forma del hocico (proyectado de perfil en T sornozai, truncado de perfil en R. orejuela), la extensión de la membrana en manos y pies (mayor en T. sornozai), la presencia de melanóforos en las manos y pies (mayor en R. orejuela), el color del iris (gris oscuro con un anillo circumpupilar amarillo en R. orejuela, vs. dorado con reticulaciones oscuras en T. sornozai), y el tamaño corporal (mayor en R. orejuela). Sin embargo, la adquisición de mayor material de R. orejuela y la re-evaluación de los especímenes asignados a T. sornozai permitieron determinar que ambos nombres corresponden a una misma especie. Las diferencias observadas en los especímenes asignados a Teratohyla sornozai se deben a variación intraespecífica (por ejemplo, el color del iris) o a cambios ontogénicos (los juveniles de R. orejuela presentan menos melanóforos en las patas, una mayor extensión en las membranas manuales y pediales). La variación en la forma del hocico parece corresponder a un patrón común observado en varias especies de Centrolenidae, donde los juveniles tienen el hocico proyectado en vista lateral o de perfil. Basados en esta nueva evidencia, colocamos a Teratohyla sornozai Cisneros-Heredia, Yánez-Muñoz y Ortega-Andrade como un sinónimo junior de Rulyrana orejuela Duellman y Burrowes (Figuras 1-2). Con este cambio, el número de localidades conocidas para Rulyrana orejuela en Ecuador se incrementa a cuatro: Mashpi, Saguangal [3], Río Naranjal y Canadé [1].

Teratohyla sornozai fue recientemente descrita [1] so-
bre la base de especímenes colectados en tres localida-
des en las provincias de Esmeraldas, Imbabura y Pichin-

tamaño corporal (mayor en R. orejuela). Sin embargo,
la adquisición de mayor material de R. orejuela y la re-
evaluación de los especímenes asignados a T. sornozai

deben a variación intraespecífica (por ejemplo, el co-
lor del iris) o a cambios ontogénicos (los juveniles de
R. orejuela presentan menos melanóforos en las patas,
una mayor extensión en las membranas manuales y pe-
diales). La variación en la forma del hocico parece co-
rresponder a un patrón común observado en varias espe-
cies de Centrolenidae, donde los juveniles tienen el ho-
cico proyectado en vista lateral o de perfil. Basados en

... Taxonomic Remarks: Teratohyla sornozai was synonymized with Sachatamia orejuela by Cisneros-Heredia et al. [287]. Examination of the type series of T. sornozai showed that all differences that separated it from S. orejuela were expressions of ontogenetic and intraspecific variation of the later. ...

Glassfrogs (family: Centrolenidae) represent a fantastic radiation (~150 described species) of Neotropical anurans that originated in South America and dispersed into Central America. In this study, we review the systematics of Ecuadorian glassfrogs, providing species accounts of all 60 species, including three new species described herein. For all Ecuadorian species, we provide new information on the evolution, morphology, biology, conservation, and distribution. We present a new molecular phylogeny for Centrolenidae and address cryptic diversity within the family. We employ a candidate species system and designate 24 putative new species that require further study to determine their species status. We find that, in some cases, currently recognized species lack justification; specifically, we place Centrolene gemmata and Centrolene scirtetes under the synonymy of Centrolene lynchi; C. guanacarum and C. bacata under the synonymy of Centrolene sanchezi; Cochranella phryxa under the synonymy of Cochranella resplendens; and Hyalinobatrachium ruedai under the synonymy of Hyalinobatrachium munozorum. We also find that diversification patterns are mostly congruent with allopatric speciation, facilitated by barriers to gene flow (e.g., valleys, mountains, linearity of the Andes), and that niche conservatism is a dominant feature in the family. Conservation threats are diverse, but habitat destruction and climate change are of particular concern. The most imperiled glassfrogs in Ecuador are Centrolene buckleyi, C. charapita, C. geckoidea, C. medemi, C. pipilata, Cochranella mache, Nymphargus balionotus, N. manduriacu, N. megacheirus, and N. sucre, all of which are considered Critically Endangered. Lastly, we identify priority areas for glassfrog conservation in Ecuador.
... However, we prefer to wait for the results of the work of others (M. A. Rada, in prep.) that include a cladistic analysis of large set of phenotypic characters to test the absence of diagnostic characters. Our topology confirms the assignment of Rulyrana orejuela (where it was placed without discussion by Cisneros-Heredia et al. 2011 to Sachatamia. Although this relationship was implicit in the trees of Castroviejo-Fisher et al. (2014), it was not discussed. ...

Peru is well known for amphibian diversity and endemism, yet there have been relatively few field studies of glassfrog (Centrolenidae) diversity in this country. Research in Colombia and Ecuador indicates that centrolenid diversity is higher in the northern Andes. However, part of this trend appears to be due to sampling effort. We conducted fieldwork through- out northern Peru, and based on phylogenetic analysis of DNA sequences, combined with bioacoustic and morphological analyses of new and available material we now recognize 33 species from the country (versus 30 species prior to this work). Field surveys led to the discovery of four remarkable species: Centrolene charapita new species is a large, orna- mented glassfrog that appears to be sister to Ce. geckoideum; Chimerella corleone new species represents the second- known member of the genus Chimerella; Cochranella guayasamini new species is the second-known member of the ge- nus with humeral spines; and Hyalinobatrachium anachoretus new species occurs in the cloud forest of the east-Andean versant in Peru. In addition to the new species described here, we provide new country records, new localities including range extensions of up to 875 km, information on diagnostic characters and phylogenetic relationships, call and larval de- scriptions, and observations on natural history for several Peruvian centrolenids. Our results also revealed several taxo- nomic problems concerning species of the genus Rulyrana, and we conclude that R. croceopodes and R. tangarana are junior synonyms of R. saxiscandens. By implication of our phylogenetic analyses, we recognize the following new com- binations: Espadarana audax new combination, Espadarana durrelorum new combination, and Espadarana fernandoi new combination.

We describe a new species of Glassfrog of the family Centrolenidae. This new taxon, Terarohyla sornozai sp. nov., is diagnosed by having a protruding snout in lateral profile, uniform green dorsal colouration in life, concealed prepollex, extensive webbing between the outer fingers, fully webbed toes, and small body size. It inhabits the Non-Seasonal Evergreen Foothill and Lowland forests in the provinces of Esmeraldas, Imbabura, and Pichincha, north-western Ecuador.
