Frogs The first vertebrates to vocalize on land Hylidae: Dendropsophus microcephalus Males communicate to females (and other males) through a series of auditory sounds. The most prominent of which is the advertisement call. Hylidae: Hyla cinerea Anatomy of a Frog Call Anaxyrus fowleri | FOWLER’S TOAD Frogs of the World Ascaphidae Fejérváry, 1923 (2 sp.) Tailed Frogs are found in the northwestern United States. Genera (1): Ascaphus Stejneger, 1899 (2 sp.) They are considered the most primitive of the modern frogs (Anura). Synapomorphies The most striking feature of this group is the external copulatory organ (an everted extension of the cloaca), used during internal fertilization, which takes place under water in fast flowing streams. Tadpoles have large sucker-like mouths (gastromyzophory) to aid in clasping to rocks while they feed. Tadpoles may take up to 7 years to metamorphose, although 4 is average. They are small, brown or gray, have reduced lungs, and vertical pupils. Males do not vocalize. Morphological features for this group are: 1) 9 presacral vertebrae; 2) sternum cartilaginous, omosternum present; 3) urostyle with one condyle; 4) free ribs present on 3rd, 4th, and 5th vertebrae; 5) pectoral girdle arciferal; 6) clavicle overlies scapula; 7) maxilla and premaxillae contain teeth; 10) sartorious not a separate muscle; 11) aquatic larvae (Type III); 12) pupil vertically elliptical; 13) internal fertilization.

Mivart, 1869 (4 sp.) Bell Frogs are found in New Zealand. Genera (1): Leiopelma Fitzinger, 1861 Synapomorphies Adults guard their clutches of direct-developing eggs. Young of L. hamiltoni and L. archeyi climb onto the backs of parents to complete their development. Leiopelmatids are nocturnal and catch their prey by lunging at it, as they do not have protrusible tongues (unlike most frogs). They also use alternating kicks when swimming (unlike most frogs). This family does not vocalize, but frogs are known to squeak when molested. These frogs possess: 1) inscriptional ribs (cartilage embedded within abdominal muscle); 2) nine presacral vertebrae (as in Ascaphidae); 3) retention of caudalipuboischiotibialis ("tail-wagging") muscles (as in Ascaphidae). Ascaphus and Leiopelma share many primitive characters, and there are apparently no derived characters that unite them as closest relatives. However, DNA sequences consistently place Ascaphidae and Leiopelmatidae as closest relatives. Leiopelmatidae. Mivart, 1869 (4 sp.)

Genera (2): Barbourula Taylor and Noble, 1924 (2 sp.) Bombina Oken, 1816 (6 sp.) Synapomorphies Species of Bombina are active during the day and have aposematic coloration ventrally.

New genetic data suggest that real S. everetti is a SW Mindanao species...not sure what the Apo population would be since it has not be included in a phylogenetic study (Brown). No inferences can be made on the basis of habitat or forest cover. Need actual surveys of populations (Brown). Recommended to be listed as Data Deficient, for its distribution. Data Deficient because no studies can be conducted in that region due to security issues (Brown).

  • A New Species of the Genus Nasikabatrachus (Anura, Nasikabatrachidae) from the Eastern Slopes of the Western Ghats, India

We describe a new species of the endemic frog genus Nasikabatrachus,from the eastern slopes of the Western Ghats, in India. The new species is morphologically, acoustically and genetically distinct from N. sahyadrensis. Computed tomography scans of both species revealed diagnostic osteological differences, particularly in the vertebral column. Male advertisement call analysis also showed the two species to be distinct. A phenological difference in breeding season exists between the new species (which breeds during the northeast monsoon season; October to December), and its sister species (which breeds during the southwest monsoon; May to August). The new species shows 6 % genetic divergence (K2P) at mitochondrial 16S rRNA (1330 bp) partial gene from its congener, indicating clear differentiation within Nasikabatra- chus. Speciation within this fossorial lineage is hypothesized to have been caused by phenological shift in breeding during different monsoon seasons—the northeast monsoon in the new species versus southwest monsoon in N.

All known species of this genus, their type specimens, current taxonomic status, and geographical distribution are revised, based on museum and field studies. In addition, 12 new species are described and compared with other members of the genus, especially with the name-bearing types of Indian Philautus. Diagnoses, detailed descriptions, illustrations, data on distribution, and natural history are provided for all species, and their relationships are estimated using molecular phylogenetic analyses of mitochondrial data sets. No reliable observations have been made for two species, Philautus chalazodes (Günther, 1876) and Philautus flaviventris (Boulenger, 1882), since the original descriptions in the 19th century. © 2009 The Linnean Society of London, Zoological Journal of the Linnean Society, 2009, 155, 374–444.

These Amphibia choices can strongly affect the resulting topologies. Here, we explore two controversial approaches (binning Anura genes into “supergenes” and inclusion of only rapidly evolving sites), using new data from hyloid frogs. Hyloid Biogeography frogs encompass ∼53% of frog species, including true toads (Bufonidae), glassfrogs (Centrolenidae), poison Naive binning frogs (Dendrobatidae), and treefrogs (Hylidae). Many hyloid families are well-established, but relationships Phylogenomics among these families have remained difficult to resolve. We generated a dataset of ultraconserved elements Statistical binning (UCEs) for 50 ingroup species, including 18 of 19 hyloid families and up to 2214 loci spanning > 800,000 aligned base pairs.

    Evolutionary History of the Asian Horned Frogs (Megophryinae): Integrative Approaches to Timetree Dating in the Absence of a Fossil Record Stephen Mahony,*,1,2 Nicole M. Foley,1 S.D. Biju,2 and Emma C. Teeling*,1 1School of Biology and Environmental Science, University College Dublin, Belfield, Dublin, Ireland 2Systematics Lab, Department of Environmental Studies, University of Delhi, Delhi, India *Corresponding authors: E-mails: [email protected]; [email protected]. Associate editor: Beth Shapiro Abstract Downloaded from https://academic.oup.com/mbe/article-abstract/34/3/744/2919384 by guest on 06 August 2019 Molecular dating studies typically need fossils to calibrate the analyses. Unfortunately, the fossil record is extremely poor or presently nonexistent for many species groups, rendering such dating analysis difficult. One such group is the Asian horned frogs (Megophryinae). Sampling all generic nomina, we combined a novel 5 kb dataset composed of four nuclear and three mitochondrial gene fragments to produce a robust phylogeny, with an extensive external morpho- logical study to produce a working taxonomy for the group. Expanding the molecular dataset to include out-groups of fossil-represented ancestral anuran families, we compared the priorless RelTime dating method with the widely used prior-based Bayesian timetree method, MCMCtree, utilizing a novel combination of fossil priors for anuran phylogenetic dating. The phylogeny was then subjected to ancestral phylogeographic analyses, and dating estimates were compared with likely biogeographic vicariant events. Phylogenetic analyses demonstrated that previously proposed systematic hypotheses were incorrect due to the paraphyly of genera. Molecular phylogenetic, morphological, and timetree results support the recognition of Megophryinae as a single genus, Megophrys, with a subgenus level classification.
