A New Species of Skin-Feeding Caecilian and the First Report of Reproductive Mode in Microcaecilia (Amphibia: Gymnophiona: Siphonopidae)
A new species of siphonopid caecilian, Microcaecilia dermatophagasp. nov., is described based on nine specimens from French Guiana. The new species is the first new caecilian to be described from French Guiana for more than 150 years. It differs from all other Microcaecilia in having fewer secondary annular grooves and/or in lacking a transverse groove on the dorsum of the first collar. Observa...
متن کاملTaxonomic Status of the Neotropical Caecilian Genera Brasilotyphlus Taylor, 1968, Microcaecilia Taylor, 1968 and Parvicaecilia Taylor, 1968 (amphibia: Gymnophiona: Siphonopidae)
We review the taxonomic history and assess the status of three genera of siphonopid caecilians from South America. Evidence from dentition and squamation suggest that Microcaecilia is paraphyletic with respect to Parvicaecilia. To avoid this paraphyly we propose to relegate the latter to the synonymy of the former. We find no evidence warranting any change in the taxonomic status of Brasilotyph...
متن کاملA new lungless caecilian (Amphibia: Gymnophiona) from Guyana.
We report the discovery of a single specimen of a small, terrestrial, lungless caecilian, the second known taxon of lungless caecilians. It differs from all other caecilians in lacking open external nares, and from the large aquatic lungless species described by Nussbaum & Wilkinson (Nussbaum, R. A. & Wilkinson, M. 1995 Proc. R. Soc. Lond. B 261, 331-335) in having no significant skull modifica...
متن کاملA mark–recapture study of the caecilian amphibian Gegeneophis ramaswamii (Amphibia: Gymnophiona: Caeciliidae) in southern India
The potentially important ecology of subterranean predators of soil ecosystem engineers is poorly understood. This is especially true of caecilian amphibians (Gymnophiona) for which there are virtually no quantitative data. Results of the first field trials of permanent marking in caecilians are presented. A preliminary assessment is made of the efficacy of mark–recapture studies for estimating...
متن کاملEmbryonic and larval development in the caecilian Ichthyophis kohtaoensis (Amphibia, gymnophiona): a staging table.
Little is known about the developmental biology of caecilians-tropical, elongate, limbless, mostly fossorial amphibians that are members of the Order Gymnophiona. Ichthyophis kohtaoensis (Family Ichthyophiidae; southeast Asia) is an oviparous species in which maternal care of the clutch is provided. The clutch is laid in a burrow on land, and the embryos develop in their egg membranes, curved a...
