Both species, commensal on Acanthixalus spinosus, are hast-specifie. Light microscopy showed the existence of a posterior secant system in Opalina proteus n.sp. and its absence in Cepedea couillardi n.sp. (in agreement with the differences presently recognised between the two genera). At the ultrastructural level, however, bath species present a posterior fibrillar zone that seems to be homologous with the secant system. This apparent contradiction may be explained by the fact that the secant system is visible under light microscopy only in O. proteus because its fibrillar zone is more developed than in C. couillardi. The life cycle of C. couillardi spans stages from the tadpole to the adult; in contrast, O. proteus completes its cycle before metamorphosis of the hast. Résumé: Les auteurs ont étudié la morphologie et l'ultrastructure de deux nouvelles opalines par imprégnation à l'argent en microscopie optique et en microscopie électronique, après fixation par une technique réputée préserver les microfibrilles. -

China 4 Department of Pathology, University of Chicago, Chicago, USA Antimicrobial peptides secreted by the skin of many amphibians play an important role Received 30/8/04 in innate immunity. From two skin cDNA libraries of two individuals of the Chinese red Revised 4/2/05 belly toad (Bombina maxima), we identified 56 different antimicrobial peptide cDNA Accepted 14/2/05 sequences, each of which encodes a precursor peptide that can give rise to two kinds of [DOI 10.1002/eji.200425615] antimicrobial peptides, maximin and maximin H. Among these cDNA, we found that the mean number of nucleotide substitution per non-synonymous site in both the maximin and maximin H domains significantly exceed the mean number of nucleotide substitution per synonymous site, whereas the same pattern was not observed in other structural regions, such as the signal and propiece peptide regions, suggesting that these antimicrobial peptide genes have been experiencing rapid diversification driven by Darwinian selection. -
Ecol 483/583 – Herpetology Lab 3: Amphibian Diversity 2: Anura Spring 2010
Ecol 483/583 – Herpetology Lab 3: Amphibian Diversity 2: Anura Spring 2010 P.J. Bergmann & S. Foldi (Modified from Bonine & Foldi 2008) Lab objectives The objectives of today’s lab are to: 1. Familiarize yourself with Anuran diversity. 2. Learn to identify local frogs and toads. 3. Learn to use a taxonomic key. Today’s lab is the second in which you will learn about amphibian diversity. We will cover the Anura, or frogs and toads, the third and final clade of Lissamphibia. Tips for learning the material Continue what you have been doing in previous weeks. Examine all of the specimens on display, taking notes, drawings and photos of what you see. Attempt to identify the local species to species and the others to their higher clades. Quiz each other to see which taxa are easy for you and which ones give you troubles, and then revisit the difficult ones. Although the Anura has a conserved body plan – all are rather short and rigid bodied, with well- developed limbs, there is an incredible amount of diversity. Pay close attention to some of the special external anatomical traits that characterize the groups of frogs you see today. You will also learn to use a taxonomic key today. This is an important tool for correctly identifying species, especially when they are very difficult to distinguish from other species. 1 Ecol 483/583 – Lab 3: Anura 2010 Exercise 1: Anura diversity General Information Frogs are a monophyletic group comprising the order Anura. Salientia includes both extant and extinct frogs. Frogs have been around since the Triassic (~230 ma). -
Analyses of Proposals to Amend
CoP17 Prop. 38 Inclusion of False Tomato Frog Dyscophus guineti and Antsouhy Tomato Frog D. insularis in Appendix II Proponent: Madagascar Summary: The False Tomato Frog Dyscophus guineti and the Antsouhy Tomato Frog D. insularis comprise two of three species in the genus Dyscophus, all of which are endemic to Madagascar. The third species, D. antongilii was included in Appendix I in 1987. It is subject to a separate proposal to be transferred from Appendix I to Appendix II (Proposal 37). All three are attractive red-orange coloured frogs. Dyscophus are known to breed explosively with the availability of water during the rainy season (typically January-March) and during that time they can be found in abundance at breeding sites. Hundreds of eggs are laid in water following mating. Dyscophus guineti The known distribution of D. guineti includes a number of patches in the remnant central eastern rainforest of Madagascar. The species is secretive and believed likely to be more widespread than records indicate1. Overall population is unknown; locally the species can vary from extremely common to very rare1. Sexual maturity is attained between two and four years, comparatively earlier in males than in females2. The habitat of the species is affected by conversion of forest to agriculture, timber extraction, charcoal production and potentially small-scale mining activities. The species reportedly does not tolerate severe degredation1. There is not known to be local use of the species. As a consequence of the Appendix-I listing in 1987 of the similar Dyscophus antongilii, collectors interested in "red Dyscophus" have shifted their attention to D. -
Congolius, a New Genus of African Reed Frog Endemic to The
www.nature.com/scientificreports OPEN Congolius, a new genus of African reed frog endemic to the central Congo: A potential case of convergent evolution Tadeáš Nečas1,2*, Gabriel Badjedjea3, Michal Vopálenský4 & Václav Gvoždík1,5* The reed frog genus Hyperolius (Afrobatrachia, Hyperoliidae) is a speciose genus containing over 140 species of mostly small to medium-sized frogs distributed in sub-Saharan Africa. Its high level of colour polymorphism, together with in anurans relatively rare sexual dichromatism, make systematic studies more difcult. As a result, the knowledge of the diversity and taxonomy of this genus is still limited. Hyperolius robustus known only from a handful of localities in rain forests of the central Congo Basin is one of the least known species. Here, we have used molecular methods for the frst time to study the phylogenetic position of this taxon, accompanied by an analysis of phenotype based on external (morphometric) and internal (osteological) morphological characters. Our phylogenetic results undoubtedly placed H. robustus out of Hyperolius into a common clade with sympatric Cryptothylax and West African Morerella. To prevent the uncovered paraphyly, we place H. robustus into a new genus, Congolius. The review of all available data suggests that the new genus is endemic to the central Congolian lowland rain forests. The analysis of phenotype underlined morphological similarity of the new genus to some Hyperolius species. This uniformity of body shape (including cranial shape) indicates that the two genera have either retained ancestral morphology or evolved through convergent evolution under similar ecological pressures in the African rain forests. African reed frogs, Hyperoliidae Laurent, 1943, are presently encompassing almost 230 species in 17 genera. -

Overview The genus Dyscophus contains three species of large microhylids composing the subfamily Dyscophinae endemic to Madagascar. D. antongilii, D. guineti and D. insularis. Dyscophus antongilii is red-orange in coloration and commonly called the tomato frogs because of its appearance. It is well-known and iconic amphibian species. Described by Alfred Grandidier in the 1877, D. antongilii occurs in a moderate area of northeast and east of Madagascar. Dyscophus antongilii has been listed within CITES Appendix I since 1987 while the other two species currently have no CITES listing but proposed to be inserted into Appendix II for this year by a separate proposal. Some studies on the species led by F. Andreone demonstrate that this species is frequently found outside of protected area and one of the strategies to conservation purpose is the trade. The species is listed as Near Threatened on the IUCN Red List. -

New Record of Corythomantis Greeningi Boulenger, 1896 (Amphibia, Hylidae) in the Cerrado Domain, State of Tocantins, Central Brazil
Herpetology Notes, volume 7: 717-720 (2014) (published online on 21 December 2014) New record of Corythomantis greeningi Boulenger, 1896 (Amphibia, Hylidae) in the Cerrado domain, state of Tocantins, Central Brazil Leandro Alves da Silva1,*, Mauro Celso Hoffmann2 and Diego José Santana3 Corythomantis greeningi is a hylid frog distributed Caatinga. This new record extends the distribution of along xeric and subhumid regions of northeastern Corythomantis greeningi around 160 km western from Brazil, usually associated with the Caatinga domain the EESGT, which means approximately 400 km from (Jared et al., 1999). However, recent studies have shown the edge of the Caatinga domain (Figure 1). Although a larger distribution for the species in the Caatinga and Corythomantis greeningi has already been registered Cerrado (Valdujo et al., 2011; Pombal et al., 2012; in the Cerrado, this record shows a wider distribution Godinho et al., 2013) (Table 1; Figure 1).

E.mail: [email protected] Submitted on: 2009, 23th November; revised on 2010, 10th October; accepted on 2010, 12th November. Abstract. The tadpoles of Yellow-bellied toad (Bombina variegata) can be easily rec- ognized from other Italian anuran species, except those of B. pachypus (though the two congeneric species are allopatric). In this paper we report morphometric data on B. variegata tadpoles from a Lombard population living near a torrent at 450 m a.s.l. On a sample of 264 tadpoles (stages 19-44, according to Gosner, 1960) we meas- ured the following five variables: snout-vent length, tail length, maximum tail height, total length and weight. We found a slight allometric relationship between snout-vent length and tail length, while, as expected, the weight is nearly proportional to the cube of linear measures. According to literature data, our results point to highly constant proportions during the development phases up to prometamorphic stages. The ratio between snout-vent length and tail length was about 0.75 during the whole growing phase, while from stage 42 the proportion increases as the resorption of the tail starts. Keywords.
