Amphibia: Gymnophiona) Is Not Lungless: Implications for Taxonomy and for Understanding the Evolution of Lunglessness

Email: [email protected] Abstract According to current understanding, five lineages of amphibians, but no other tetrapods, are secondarily lungless and are believed to rely exclusively on cutaneous gas exchange. One explanation of the evolutionary loss of lungs interprets lung- lessness as an adaptation to reduce buoyancy in fast-flowing aquatic environments, reasoning that excessive buoyancy in such an environment would cause organisms being swept away. While not uncontroversial, this hypothesis provides a plausible potential explanation of the evolution of lunglessness in four of the five lungless amphibian lineages. The ex- ception is the most recently reported lungless lineage, the newly described Guyanan caecilian genus and species Caecilita iwokramae Wake & Donnelly, 2010, which is inconsistent with the reduced disadvantageous buoyancy hypothesis by vir- tue of it seemingly being terrestrial and having a terrestrial ancestry. -
Morphological Evolution and Modularity of the Caecilian Skull Carla Bardua1,2* , Mark Wilkinson1, David J
Bardua et al. BMC Evolutionary Biology (2019) 19:30 https://doi.org/10.1186/s12862-018-1342-7 RESEARCH ARTICLE Open Access Morphological evolution and modularity of the caecilian skull Carla Bardua1,2* , Mark Wilkinson1, David J. Gower1, Emma Sherratt3 and Anjali Goswami1,2 Abstract Background: Caecilians (Gymnophiona) are the least speciose extant lissamphibian order, yet living forms capture approximately 250 million years of evolution since their earliest divergences. This long history is reflected in the broad range of skull morphologies exhibited by this largely fossorial, but developmentally diverse, clade. However, this diversity of form makes quantification of caecilian cranial morphology challenging, with highly variable presence or absence of many structures. Consequently, few studies have examined morphological evolution across caecilians. This extensive variation also raises the question of degree of conservation of cranial modules (semi-autonomous subsets of highly-integrated traits) within this clade, allowing us to assess the importance of modular organisation in shaping morphological evolution. We used an intensive surface geometric morphometric approach to quantify cranial morphological variation across all 32 extant caecilian genera. We defined 16 cranial regions using 53 landmarks and 687 curve and 729 surface sliding semilandmarks. With these unprecedented high-dimensional data, we analysed cranial shape and modularity across caecilians assessing phylogenetic, allometric and ecological influences on cranial evolution, as well as investigating the relationships among integration, evolutionary rate, and morphological disparity. Results: We found highest support for a ten-module model, with greater integration of the posterior skull. Phylogenetic signal was significant (Kmult =0.87,p < 0.01), but stronger in anterior modules, while allometric influences were also significant (R2 =0.16,p < 0.01), but stronger posteriorly. -

E-mail: [email protected] ! Currently the Department of Life Sciences Abstract A new species of striped ichthyophiid caecilian, Ichthyophis multicolor sp. nov., is described on the basis of morpholog- ical and molecular data from a sample of 14 specimens from Ayeyarwady Region, Myanmar. The new species resembles superficially the Indian I. tricolor Annandale, 1909 in having both a pale lateral stripe and an adjacent dark ventrolateral stripe contrasting with a paler venter. It differs from I. tricolor in having many more annuli, and in many details of cranial osteology, and molecular data indicate that it is more closely related to other Southeast Asian Ichthyophis than to those of South Asia. The caecilian fauna of Myanmar is exceptionally poorly known but is likely to include chikilids as well as multiple species of Ichthyophis. -

Both series were founded by Dr. Bryant Walker, Mr. Bradshaw H. Swales, and Dr. W. W. Newcomb. Occasionally the Museum publishes contributions outside of these series. Beginning in 1990 these are titled Special Publications and Circulars and each are sequentially numbered. All submitted manuscripts to any of the Museum’s publications receive external peer review. The Occasional Papers, begun in 1913, serve as a medium for original studies based principally upon the collections in the Museum. They are issued separately. When a sufficient number of pages has been printed to make a volume, a title page, table of contents, and an index are supplied to libraries and individuals on the mailing list for the series. The Miscellaneous Publications, initiated in 1916, include monographic studies, papers on field and museum techniques, and other contributions not within the scope of the Occasional Papers, and are published separately. Each number has a title page and, when necessary, a table of contents. A complete list of publications on Mammals, Birds, Reptiles and Amphibians, Fishes, Insects, Mollusks, and other topics is available. -

First Record of the Genus Microcaecilia Taylor, 1968 (Amphibia, Gymnophiona: Siphonopidae) from Peru
Herpetology Notes, volume 8: 55-57 (2015) (published online on 10 March 2015) First record of the genus Microcaecilia Taylor, 1968 (Amphibia, Gymnophiona: Siphonopidae) from Peru Jhon J. López-Rojas1,* and Devon Graham2,3 Abstract. We report the first record of the genus Microcaecilia in Peru from lowland, primary rainforest in Loreto, adding to its previously known geographic range from northwestern Colombia; Ecuador through southern Venezuela to the Guianas and São Paulo, Brazil. Two individuals of a species of this genus of small caecilians were found in deep leaf litter at the Reserva Forestal Santa Cruz, located approximately 30 km northeast of the city of Iquitos. We refer to these specimens as Microcaecilia sp. because of the current difficulty in confidently determining their identity.
