Descrição do girino de Cochranella resplendens e redescrição do girino de Hyalinobatrachium aureoguttatum (Anura, Centrolenidae)

Abstract

Description of the tadpole of Cochranella resplendens and redescription of the tadpole of Hyalinobatrachium aureoguttatum (Anura, Centrolenidae). The tadpole of Cochranella resplendens is described and that of Hyalinobatrachium aureoguttatum is redescribed; information on their ontogenetic variation also is included. Cochranella resplendens is characterized by having a non-emarginated oral apparatus and an upper jaw sheath nearly straight with a smooth arch in the middle. Hyalinobatrachium aureoguttatum has an emarginated oral apparatus with a characteristic M-shaped upper jaw sheath and bears few (1-5) submarginal papillae on the upper labium. Although the two species show few changes in the oral apparatus during their development (except for changes in Gosner Stages 24 and 42 in C. resplendens and 23-24 in H. aureoguttatum), there are major ontogenetic changes in size and coloration.Keywords: Anura, Centrolenidae, larvae, ontogeny, Ecuador. Resumen Descripción del renacuajo de Cochranella resplendens y redescripción del renacuajo deHyalinobatrachium aureoguttatum (Anura, Centrolenidae). Se describe el renacuajo de Cochranella resplendens y se redescribe el de Hyalinobatrachium aureoguttatum, incluyendo información sobre su variación ontogénica. Cochranella resplendens se caracteriza por tener un aparato oral sin inflexión intramarginal y un supraquerostoma casi recto, aunque ligeramente arqueado en la mitad. Por otro lado, H. aureoguttatum tiene un aparato oral con inflexión intramarginal; presenta un característico supraquerostoma en forma de "M" y pocas papilas intramarginales (1-5) en el labio superior. Ninguna de las dos especies mostró una variación significativa en el aparato oral durante su desarrollo (excepto en los estadios Gosner 24 y 42 en C. resplendens y 23-24 en H. aureoguttatum). Los cambios ontogénicos más evidentes fueron en el tamaño y la coloración.Palabras claves: Anura, Centrolenidae, larva, ontogenia, Ecuador. Phyllomedusa -8(2), December 2009106 Resumo Descrição do girino de Cochranella resplendens e redescrição do girino de Hyalinobatrachium aureoguttatum (Anura, Centrolenidae). Descrevemos o girino de Cochranella resplendens e redescrevemos o girino de Hyalinobatrachium aureoguttatum, incluindo informação sobre sua variação ontogenética. Cochranella resplendens caracteriza-se por apresentar um aparato oral sem inflexão intramarginal e a porção superior do bico córneo quase reta, ainda que ligeiramente arqueado na porção mediana. Por outro lado, H. aureoguttatum possui aparato oral com inflexão intramarginal e apresenta a porção superior do bico córneo característica, em forma de "M", e poucas papilas intramarginais (1-5) no lábio superior. Nenhuma das duas espécies mostrou uma variação significativa no aparato oral durante o desenvolvimento (exceto nos estágios 24 e 42 de Gosner em C. resplendens e 23-24 em H. aureoguttatum). As mudanças ontogenéticas mais evidentes estão relacionadas com o tamanho e a coloração.

The poverty of adult morphology: Bioacoustics, genetics, and internal tadpole morphology reveal a new species of glassfrog (Anura: Centrolenidae: Ikakogi) from the Sierra Nevada de Santa Marta, Colombia

“…There are many records of fossorial habits in the literature for centrolenid larvae (e.g. [106, 38, 49, 54, 51, 52]). Altig and Johnston [107] placed centrolenids in the fossorial ecomorphological guild Type I and enumerated a series of characters for that guild: i) LTRF 2/3; ii) a small oral disc; iii) incomplete anterior marginal papillae; iv) very small eye (at least during the first stages but gradually increasing the size); and v) very often, red coloration due to highly vascular skin.…”

Amphibia, Anura, Centrolenidae, Cochranella resplendens (Lynch & Duellman, 1973): first record from Brazil and updated map of the geographic distribution

“…We have obtained Fourteen known locality records for C. resplendens from Lynch and Duellman (1973), Cisneros-Heredia andMcDiarmid (2005), Terán-Valdez et al (2009), Malambo et al (2013), Twomey et al (2014), Chávez and Mueses-Cisneros (2016), , Restrepo et al (2017), andRojas-Padilha et al (2019). Additionally, we also obtained more two distribution records at speciesLink database (speciesLink, 2019), totaling 16 records.…”

Mating patterns and post-mating isolation in three cryptic species of the Engystomops petersi species complex

“…Nests were checked at least twice a day. As soon as the first tadpole emerged, we oxygenated the water with aquarium pumps and fed tadpoles ad libitum with Super Alimento de Renacuajos (SAR: protein– 27%, humidity = 10.02%, fiber = 42.66% and Carbohydrates = 48.82% [21,22]). Latency to hatch was recorded as the number of days it took for the first tadpoles to emerge from the nest.…”
