A new species, Xenophrys insularis sp. nov., is described based on a series of specimens collected from Nan’ao Island, Shantou City, Guangdong Province, China. The new species is a separately evolving lineage that was robustly supported by the phylogenetic analysis based on the mitochondrial CO1 + 12S rRNA + 16S rRNA genes; morphologically, it can be distinguished from other known congeners by the following combination of characteristics: body size moderate, SVL 38.6–41.2 mm in adult males, 47.1 mm in a single adult female; snout obtusely rounded in dorsal view; head width slightly larger than head length; strong vomerine ridge bearing vomerine teeth; margin of tongue weakly notched behind; supratympanic fold forming a large swollen supraaxillary gland above insertion of arm; hindlimbs relatively short, heels not meeting when thighs are held at right angles to body, tibio-tarsal articulation reaches forward the posterior edge of tympanum; fingers and toes without lateral fringes, with rudiment of web at bases of toes, distinct subarticular tubercle only at the base of each finger and toe; single vocal sac in males; gravid female bears pure white oocytes. Xenophrys insularis sp. nov. is endemic to the Nan’ao Island and represents the first Xenophrys species found on and possibly endemic to a small offshore island.

A new species, Amolops yunkaiensis sp. nov. is described based on a series of specimens from Ehuangzhang Nature Reserve and Yunkaishan Nature Reserve, southwestern Guangdong Province, China. The new species can be distinguished from all known congeners by molecular divergence in the mitochondrial 16S rRNA, 12S rRNA and CO1 genes, and a combination of the following characters: relatively small body size, SVL 31.8–34.1 mm in adult males, 35.2–39.0 mm in adult females; numerous raised large warts on dorsum and flanks; dorsal body olive-brown or light brown with dark brown blotches; absence of vomerine teeth; absence of tarsal glands; presence of a pair of subgular vocal sacs, nuptial spines on the first finger, and sparse translucent tubercles on the lower jaw, forechest, posterior belly and ventral thigh in male. Hence, the genus Amolops contains 52 species, 29 of which occur in China.

Using molecular genetics, male sexual organ morphology (baculum), and cranio-dental characters, we describe a new spe-cies of the genus Neoromicia from Madagascar, N. robertsi sp. nov. It is presumed to be endemic to the island and isknown from three specimens taken in montane areas of the eastern central region. The new species shows 1.0 % and 2.8%divergence in the 12S rRNA and 16S rRNA genes, respectively, from its nearest congener and is notably larger in cranio-dental measurements than other members of the genus occurring on Madagascar. This new species was previously iden-tified as N. melckorum, which is considered a junior synonym of southern African N. capensis. Neoromicia malagasyen-sis, an endemic to central western Madagascar, is the sister species to N. robertsi and the two are best considered vicariantspecies. Specimens provisionally assigned to N. malagasyensis, but notably smaller in baculum and skull size, and withdifferent baculum morphology, probably represent another unknown species from the island. Given the apparent rarity ofN. robertsi compared with other Malagasy members of this genus living in the eastern portion of Madagascar, it is considered a taxon of conservation concern.

We review the systematics of frogs of the Hyloscirtus larinopygion group. A new phylogenetic tree inferred frommitochondrial DNA (partial sequences of 12S rRNA, valine-tRNA, and 16S rRNA genes; ~2.3 kb) of eleven species ofthe H. larinopygion group is provided, based on maximum parsimony, maximum likelihood, and Bayesian analyses. Ourphylogeny confirms the close relationship of members of the H. larinopygion group with Andean relatives of the H.armatus group, which also occurs in the Andes. Hyloscirtus tapichalaca is placed as sister species to the rest of the H.larinopygion group, in which two clades (A+B) are evident. Although ingroup relationships are well supported, themonophyly of the H. larinopygion group and placement of H. tapichalaca require additional testing. Genetic divergencesamong species of the H. larinopygion group are shallow compared to those observed in many other anurans, with geneticdistance among sister species (H. princecharlesi and H. ptychodactylus) as low as 1.31%. However, this pattern isconcordant with radiations in other highland Andean lineages of anurans that show marked morphological or behavioraldifferentiation, but low divergence in mitochondrial markers. Divergence-time analyses (using BEAST) indicate that theHyloscirtus clade is a relatively ancient lineage that appeared in the Eocene, at a minimum age of 51.2 million years ago(MYA), while the H. larinopygion group originated in the Middle-Late Eocene at a minimum age of 40.9 MYA. Ourresults might suggest a rapid radiation of Hyloscirtus starting in the Miocene into the Pliocene, from at least 14.2 MYA tothe most recent divergence between sister taxa at ~2.6 MYA. We also describe two sympatric new species of Hyloscirtusfrom northwestern Ecuador: H. criptico sp. nov. and H. princecharlesi sp. nov. We diagnose them by their phylogeneticposition (they are not sister to each other), genetic divergence, and a unique combination of color patterns, and othermorphological features. Additionally, we describe the suctorial tadpoles and the extreme ontogenic color changes in H.larinopygion, H. lindae, H. pantostictus, H. princecharlesi, H. psarolaimus, and H. tigrinus. Furthermore, we describe theosteology of H. criptico, H. lindae, H. pacha, H. pantostictus, H. princecharlesi, H. psarolaimus, H. ptychodactylus, andH. staufferorum. We describe vocalizations of H. lindae, H. pacha, H. pantostictus, H. pasarolaimus, H. staufferorum, andH. tapichalaca. Hyloscirtus tigrinus is recorded for the first time in Ecuador and its range is extended 62.4 km (airlinedistance), from its southernmost locality record in Departamento de Nariño, Colombia. Most species of the H.larinopygion group are currently severely threatened by extinction, after surviving the catastrophic extinctions in the1980s and 1990s that led to the disappearance of many other sympatric anurans that bred in swiftly flowing water and hadlotic water tadpoles in the Andean highlands. Research and conservation actions are urgently needed for these species. Inorder to better call attention to these conservation issues, we name one of the new species in honor of Prince Charles ofWales, who is contributing significantly to the growth of awareness in the battle against tropical deforestation, climate change, and the catastrophic extinction of rainforest amphibians.

We describe Dendropsophus frosti sp. nov. from lowland terra firme rainforests of the headwaters of the Amazon RiverBasin in Colombia and Peru. The new species is known from only two localities, the type locality near Leticia (Departa-mento Amazonas, Colombia, 04° 06' 24.2" S, 69° 56' 57.4" W; 103 m.a.s.l.), and the paratopotypic locality, Piedras in thePutumayo basin (Departamento Loreto, Peru, 02.79278° S, 72.91750° W; 90–170 m.a.s.l.). Maximum likelihood and par-simony analyses of 2436 aligned base pairs of the 12S and 16S rRNA genes recovered the new species as a member of D.parviceps group and sister to D. brevifrons. The new species is most closely related to D. parviceps, D. brevifrons, and D.koechlini, and it can be readily distinguished from these and all other members of the D. parviceps group by, among othercharacters, its plain dorsal light brown coloration, copper iris, plain immaculate pale yellow to white venter coloration, lack of flash marks on groin and axillae, and absence of white spots on lips.

A new species of tree frog, G. guangdongensis sp nov., is described based on a series of specimens collected from Dawuling Forest Station, Mount Nankun and Nanling Nature Reserve of Guangdong Province, southeastern China. The new species is distinguished from all known congeners by a significant genetic divergence at the mitochondrial 16S rRNA gene fragment examined (p-distance ≥ 4.6%) and the following combination of morphological characters: relatively small body size (SVL 26.1–34.7 mm in adult males, 34.9–35.4 mm in adult females); upper eyelid and dorsum lacking spines; supratympanic fold and tympanum distinct; dorsal and lateral surface rough, sparsely scattered with tubercles; ventral skin granular; tibiotarsal projection absent; toe-webbing moderately developed, finger webbing rudimentary; heels slightly overlapping when flexed hindlimbs are held at right angles to the body axis; brown to beige above, with an inverse Y-shaped dark brown marking extendeing from the interorbital region to the centre of the dorsum; males with a single subgular vocal sac and protruding nuptial pads with minute granules on the dorsal surface of the base of first finger. The discovery and description of Gracixalus guangdongensis sp. nov. represents the 14th species known in this genus.

A new species Macrobrachium ramae is described from Rupnarayana river, West Bengal, India along with its molecular characterization and Scanning electron microscopy. The species shares certain characters with M.gurudeve, M.jayasreei, M.kunjuramani and M.saengphani but differs remarkably from these species in the structure and shape of rostrum, telson, appendix masculina and in the size of the proximal segment of the antennular peduncle. Molecular characterization and phylogenetic analysis of M.ramae with mitochondrial COI and 16S rRNA genes reinforce the morphological conclusion and supports the view that it is a new species.

ABSTRACT Fourteen fluoroquinolone-resistant fusobacterial strains, originating from cats or dogs, were characterized by sequencing of the 16S-23S and 16S rRNA genes and DNA-DNA hybridization and were described as a new species, Fusobacterium canifelinum. All of the strains are intrinsically resistant (MIC, >4 g/ml) to levofloxacin and other fluoroquinolones. Compared to the quinolone resistance-determining region (gyrA) of the susceptible relative F. nucleatum, we found that Ser79 was replaced with leucine and Gly83 was replaced with arginine.

A new species of horned toad, Megophrys ombrophila sp. nov., is described based on specimens found from Guadun village from Mount Wuyi in northwestern Fujian Province, China. The species is distinguished from other described Megophrys by morphology, bioacoustics, and molecular data of the 12S and 16S mitochondrial loci. The species is characterized by its rotund stature, head length approximately equal to head width, canthus rostralis well developed, tympanum large and distinct, vomerine teeth absent, margin of tongue smooth, not notched from behind, heels of the feet not meeting when femurs are held at 90° to the axis of the body and tibias are depressed against the femur, toes weakly webbed at base, dorsal skin mostly smooth with scattered granules and ridges, usually the presence of two discontinuous dorsolateral ridges, supratympanic fold distinct and well-developed, and with females ranging from 32.8–35 mm snout-to-vent length, and males ranging from 27.4–34.5 mm SVL. In its type locality, the species is sympatric with M. boettgeri and M. kuatunensis; and phylogenetically, the most closely related described species is M. obesa from southwest Guangdong province. As more cryptic species are described within the subfamily Megophryinae, the more apparent becomes the need for fine-scale molecular and phenotypic assessment to capture the many forms of this hyper-diverse group.
