On the identities of Caecilia degenerata Dunn, 1942 and of C. corpulenta Taylor, 1968 (Amphibia: Gymnophiona: Caeciliidae) with descriptions of three new species of Caecilia Linnaeus, 1758 from the Cordillera Oriental of Colombia

Abstract

The Central portion of the Cordillera Oriental of Colombia is currently reported to harbor two species of Caecilia distributed at comparable elevations on opposite versants of these Mountains. 

These are C. corpulenta, known from Virolín, Santander, at 1700–2000 m on the western slopes of the Cordillera Oriental and C. degenerata, known from Garagoa, Boyacá, and Choachí and Fomequé, Cundinamarca, at 1800–2100 m on the eastern slopes of the Cordillera Oriental. Both species have dermal scales and lack secondary grooves, and have been subjected to misidentifications by herpetologists studying the Gymnophiona of the Eastern Andes of Colombia. 

Our results indicate that only the latter species is found in Colombia and the former is restricted to Peru, leaving those populations previously referred to C. corpulenta and those distinct from C. degenerata pending names. We here present an account for C. degenerata based on material from Choachí and Fómeque, Cundinamarca, as well as descriptions of three new species from the Cordillera Oriental and adjacent Venezuela: C. atelolepis sp. nov., C. epicrionopsoides sp. nov., and C. macrodonta sp. nov. 

We also provide additional morphological information for the recently described C. pulchraserrana.

Настоящие червяги, или бесхвостые червяги, или цецилии (лат. Caeciliidae), — семейство безногих земноводных (Gymnophiona). Внешне похожи на крупных дождевых червей (отсюда название). Встречаются в тропиках Африки, Азии и Америки.

L’anfibio chiamato come Trump, come lui mette la testa sotto terra per non vedere i cambiamenti climatici Si chiama Dermophis donaldtrumpi ed è l’ultima scoperta nel campo della biodiversità marina. Si tratta di un anfibio con abitudini e caratteristiche molto particolari, che ricordano appunto quelle del presidente degli Stati Uniti Donald Trump. La creatura recentemente scoperta è quasi cieca e passa gran parte del suo tempo con la testa sotto la sabbia perché estremamente sensibile ai cambiamenti climatici dell’ambiente in cui vive. La sua reazione al problema del clima ricorda quella di Trump, tanto che l’anfibio è stato proprio catalogato con un nome ispirato al tycoon, alludendo alla linea negazionista del presidente sui cambiamenti climatici. La società EnviroBuild, che si occupa di costruzioni ecosostenibili, ha pagato 25mila dollari all’asta organizzata dalla Rainforest Trust per la raccolta fondi per la protezione di aree della foresta pluviale, e ha battezzato l’anfibio della famiglia Caeciliidae con un nome che ricorda quello del presidente Usa, Dermophis donaldtrumpi. La EnviroBuild ha pubblicato su Twitter un fotomontaggio dell’anfibio che indossa una parrucca “alla Donald Trump”, che ricorda la singolare chioma bionda del presidente. Il fatto che l’anfibio tenga costantemente la testa sotto la sabbia o il fango rimanda molto all’approccio di Trump alla questione del surriscaldamento globale. Un altro modo per sensibilizzare sul tema. tpi news

#новости | У считавшихся безвре��ными амфибий нашли способность к ядовитым укусам

У земноводных червяг выявили ядовитые железы в ротовой полости, с помощью которых они могут наносить ядовитые укусы. Ранее считалось, что эти существа безвредны.

Исследователи из Университета Юты изучали земноводных червяг (Caeciliidae), входящих в группу безногих змеиных амфибий, и обнаружили в секрете их желез во рту ферменты, способные разрушать фосфолипиды и отдельные белки.

Just a reminder that caecilians are not worms, and they are not snakes!

Caecilians are amphibians, like frogs and salamanders. (They are vertebrates).

Caecilians, like other amphibians, have a larval (tadpole) stage. Some of their larvae are free swimming, and some develop through their larval stage in the egg.

Caecilians are either aquatic or fossorial (burrowing) in tropical regions across the Neo-Tropics (Central and South America), Africa, and SE Asia.
