A new genus and two new species of minute leptodactylid frogs from northern South America, with comments upon Phyzelaphryne (Amphibia: Anura: Leptodactylidae) Naturalis
Hoogmoed, M.S.; Lescure, J..
The synonymisation of Phyzelaphryne miriamae Heyer with Eleutherodactylus nigrovittatus Andersson is denied and it is shown that both species are quite distinct in numerous characters. A new genus (Adelophryne) of minute leptodactylid frogs with pointed discs on the toes and a distinctly reduced fourth finger, containing two new species (A. adiastola spec. nov. and A. gutturosa spec. nov.) is described from northern South America. A key to separate the diminutive leptodactylid frogs with pointed toetips is given. The relationships of the new genus are not clear, but possibly are with one of the species groups of Eleutherodactylus, of the subfamily Eleutherodactylinae.

A new species of Telmatobufo (Schmidt 1852) (Anura, Calyptocephalellidae) from a remnant of the Maulino Forest, central Chile Gayana
Cuevas,César C.
A new species, Telmatobufo ignotus, from the Reserva Nacional Los Queules, Cauquenes Province, central Chile is described herein. The new taxon is hypothesized based on a new combination of adult, larval, and chromosomal characters. The new species present the more septentrional distribution on the coastal range and a very restrictive distribution area compared to its congeners; because of this, taxonomic and conservation comments are discussed and advanced.

Advertisement calls of Bolivian species of Scinax (Amphibia, Anura, Hylidae) Naturalis
Riva, Ignacio de la; Márquez, Rafael; Bosch, Jaime.
The advertisement calls of eight Bolivian species of Scinax are described including information on the calling behaviour of each species. A characteristic audiospectrogram and oscillogram are presented for each species, as well as numerical information about the spectral and temporal features of the calls. Two phenograms based on the characteristics of the mating calls are constructed, the first one using a traditional multivariate technique (UPGMA) and the second one using audiospectrogram correlation, a new technique that allows holistic comparisons of single vocalizations.

Anuran larvae as prey and hosts of invertebrates in neotropical aquatic habitats RChHN
Gambale,Priscilla Guedes; Batista,Vinícius Guerra; Oda,Fabrício Hiroiuki; Campos,Renata Mayara; Takemoto,Ricardo Massato; Bastos,Rogério Pereira.
BACKGROUND: Biotic processes, such as predation and parasitism events, are crucial for answering questions in ecology and evolution. Here, we report predation and ectoparasitism events of invertebrates upon tadpoles in aquatic habitats of southern Brazil. FINDINGS: Four lentic water bodies were sampled twice a month (December 2012 to March 2013). Those water bodies were located in the Diamante do Norte County, State of Paraná, southern Brazil. The tadpoles, Dendropsophus aff. minutus, Hypsiboas raniceps, Scinax fuscovarius, Physalaemus cuvieri and Elachistocleis bicolor were observed being predated by six different invertebrate predators. However, Leptodactylus fuscus and Pseudis sp. were also recorded on the same water bodies and were not observed being...

Call diversity of Leptodactylus natalensis Lutz, 1930 (Anura; Leptodactylidae) Pap. Avulsos de Zool. (São Paulo)
Prado,Gustavo M.; Bilate,Marcos; Wogel,Henrique.
The extensive vocal repertoire of Leptodactylus natalensis is described. The field observations were made at three forest fragments of the Tropical Atlantic Domain, in Northeast (State of Alagoas) and Southeast (State of Espírito Santo) regions of Brazil. The vocal repertoire of L. natalensis was constituted by ten notes emitted alone or in different combinations. The several vocalizations were organized in three distinct groups according to the social context in the moment of emission. L. natalensis presents extensive diversity of acoustic signals supported by variations in duration of each note, as well as in the number and sequence of emission of different notes.

Comparative tadpole morphology in three species of frogs of the genus Spinomantis (Amphibia: Mantellidae) Naturalis
Vejarano, S.; Thomas, M.; Vences, M..
We describe the tadpoles of three species of Malagasy frogs, classified in the genus Spinomantis, based on specimens identified by DNA barcoding. The tadpole of Spinomantis aglavei is a typical Orton type IV larva. The oral disc is not emarginated laterally, but has two mid-ventral folds and a labial tooth row formula of 3(2- 3)/2(1). The tadpole of S. phantasticus is similar, the oral disc being laterally emarginated and having one medial fold; LTRF is 3/3(1). A third species, S. cf. fimbriatus is also similar to the other two species; the oral disc is not laterally emarginated but has three medial folds and LTRF is 3(2-3)/3(1). One shared character is a median fold or emargination in the lower part of the oral disc, although the shape of this fold is...

Rada,Marco; Rueda-Almonacid,José Vicente; Velásquez-Álvarez,Álvaro Andrés; Sánchez-Pacheco,Santiago J..
Se describen las larvas de dos especies de la familia Centrolenidae (Hyalinobatrachium ibama y Cochranella daidalea) procedentes del flanco occidental de la cordillera Oriental en el departamento de Norte de Santander, Colombia. En la descripción de las larvas, además de las características morfológicas tradicionales, se incorporaron nuevos elementos de juicio como la longitud del tubo cloacal, la forma del rostro, el patrón de color y la posición del espiráculo, los cuales resultaron ser informativos y muy útiles en la diferenciación de las especies. Se proporciona una discusión acerca de la validez taxonómica de algunos de los caracteres morfológicos empleados usualmente en las descripciones y comparaciones de los renacuajos de la familia Centrolenidae.

ESCAPE OR BE PREYED: NEW RECORDS AND CURRENT KNOWLEDGE ON PREDATORS OF PSEUDINAE FROGS (ANURA: HYLIDAE) IN SOUTH AMERICA Acta biol.Colomb.
LANDGREF FILHO,Paulo; AOKI,Camila; SOUSA,Daiene Louveira Hokama de; SOUZA,Edivaldo Oliveira de; BRANDÃO,Reuber Albuquerque; ÁVILA,Robson Waldemar; ODA,Fabrício Hiroiuki.
ABSTRACT Neotropical amphibians play important roles as preys and predators in freshwater and terrestrial ecosystems. The subfamily Pseudinae includes small and medium-sized frogs within three genera representing 13 valid species. Most published records of predation on Pseudinae frogs are anecdotic and scarce. Herein, we provide five new reports of predation and presenting a detailed literature review on Pseudinae predation, with 15 studies published between 1983-2017. Pseudinae species were preyed at both day and night by a wide variety of predators, principally birds. Adults were preyed upon more frequently than juveniles and tadpoles. In the present study, most predators were diurnal, with birds accounting for most records. A variety of invertebrates...

Malha rodoviária e conflitos de conservação alha no cerrado: um estudo para a preservação de anfíbios - DOI: 10.4025/actascibiolsci.171 Biological Sciences
Silva, Rodrigo de Jesus; UFG; Vieira, Ludgero Cardoso Galli; UFG; Pinto, Míriam Plaza; UFG; Oliveira, Guilherme; UFG; Barreto, Bruno Souza; UFG.
A criação de unidades de conservação tem sido uma importante ferramenta para minimizar a perda de biodiversidade. Entretanto, a alocação destas unidades deve ser otimizada de forma que possam preservar o maior número de espécies sob uma série de restrições sócio-econômicas, as quais incluem o efeito da malha rodoviária sobre a biodiversidade. Utilizando um conjunto de dados sobre a distribuição de 131 espécies de anfíbios Anuros no bioma Cerrado, distribuídos em 181 células (1º de latitude e 1º de longitude), um processo de otimização foi feito através do algoritmo “simulated annealing”, disponível no programa SITES 1.0. O presente estudo apresenta duas redes de unidades de conservação para o Cerrado, uma baseada no conceito de complementaridade e a outra...

Molecular phylogeny, morphology and bioacoustics reveal five additional species of arboreal microhylid frogs of the genus Anodonthyla from Madagascar Naturalis
Vences, M.; Glaw, F.; Köhler, J.; Wollenberg, K.C..
We provide a partial revision of the microhylid frogs of the genus Anodonthyla, endemic to Madagascar, based on comprehensive molecular, bioacoustic and morphological data sets that include newly collected specimens from multiple localities. The molecular trees provide strong evidence for the polyphyly of several nominal species as they were previously defined, especially of Anodonthyla boulengeri and A. nigrigularis. As a consequence, we here resurrect the nomen Mantella pollicaris Boettger as Anodonthyla pollicaris from the synonymy of A. boulengeri, and we describe four new species, all with strong genetic divergences to other nominal species: Anodonthyla emilei from Ranomafana National Park, a comparatively medium- sized species characterized by a...

Natural history and conservation of the rediscovered Hula painted frog, Latonia nigriventer Naturalis
Bina Perl, R.G.; Gafny, S.; Malka, Y.; Renan, S.; Woodhams, D.C.; Rollins-Smith, L.; Pask, J.D.; Bletz, M.C.; Geffen, E.; Vences, M..
Dramatic global amphibian declines have recently led to an increased concern for many species of this animal class. The enigmatic Hula painted frog (Latonia nigriventer), the first amphibian to be declared extinct but unexpectedly rediscovered in 2011, has remained one of the rarest and most poorly understood amphibians worldwide. Gathering basic biological information on this species, along with an understanding of its disease-related threats remains fundamental for developing risk assessments and conservation strategies. Our surveys in recent years confirmed that L. nigriventer is a localised species with elusive habits. The species appears to follow an opportunistic breeding phenology and has a tadpole morphology similar to its well-studied sister group...

Natural history and distribution of Agalychnis craspedopus (Funkhouser, 1957) (Amphibia: Anura: Hylidae) Naturalis
Hoogmoed, M.S.; Cadle, J.E..
Aspects of reproductive behaviour, calls, clutch sizes, and larval morphology are described for Agalychnis craspedopus (Funkhouser, 1957). New distributional records extend the range of this species to southern Amazonian Peru. In most respects reproductive behaviour of A. craspedopus is similar to that of other phyllomedusine frogs. In southern Peru clutches were suspended above water-filled hollow cavities in logs, but in Ecuador tadpoles were found in a pool on the ground with no directlyoverhanging vegetation. Agalychnis craspedopus lays small clutches (mean = 17 eggs) with large eggs. Breeding possibly takes place throughout some years in southern Peru, but this undoubtedly varies depending on rainfall. Some aspects of reproductive biology, and tadpole...

New Osornophryne (Amphibia: Anura: Bufonidae) from the Atlantic Versant of the Andes in Ecuador Naturalis
Hoogmoed, M.S..
Two species of the little known genus Osornophryne are described from the Atlantic (Amazonian) versant of the Andes in Ecuador. O. guacamayo spec. nov. occurs at 2100 m, has well developed cranial ridges, rather peculiar feet with toes IV and V of about equal length and much longer than the others. It is rather gaudily patterned with black and yellow. O. antisana spec. nov. occurs at 3600 m and has a pointed snout, indistinct cranial ridges and is rather drably coloured. The single available adult male has a cloacal tube that runs down the back of the thighs and opens ventrally. It is speculated that this peculiar structure is indicative of internal fertilization. It is concluded that inguinal amplexus in this genus is not a primitive, but an advanced...

On The Identity Of Some Toads Of The Genus Bufo From Ecuador, With Additional Remarks On Andinophryne Colomai Hoogmoed, 1985 (Amphibia: Anura: Bufonidae). Naturalis
Hoogmoed, M.S..
Study of the type specimens of B. caeruleostictus Günther, 1859 and B. chanchanensis Fowler, 1913, and of fresh material showed that B. chanchanensis is a junior subjective synonym of B. caeruleostictus. Probably it is a member of the B. guttatus group. B. caeruleocellatus Fowler, 1913 is a junior subjective synonym of B. haematiticus Cope, 1862. New material of B. hypomelas Boulenger, 1913 is reported from NW Ecuador, the species is redescribed, and it is shown that this is a valid taxon, not the juvenile of B. blombergi Myers & Funkhouser, 1951 as suggested by Lynch, in Frost (1985). It is doubted whether B. intermedius Günther originates from Ecuador. It probably is a Central American or Mexican species of the B. valliceps Wiegmann, 1833 group. A...

Polytypic and polymorphic cytogenetic variations in the widespread anuran Physalaemus cuvieri (Anura, Leiuperidae) with emphasis on nucleolar organizing regions Biol. Res.
QUINDERÉ,YEDA R. S. D; LOURENÇO,LUCIANA B; ANDRADE,GILDA V; TOMATIS,CRISTIAN; BALDO,DIEGO; RECCO-PIMENTEL,SHIRLEI M.
We investigated the NOR distribution in ten populations of Physalaemus cuvieri from different regions of Brazil and Argentina. A high variability in NOR pattern was observed and provided a useful tool in grouping several populations. The specimens from the state of Tocantins, northern Brazil, could easily be distinguished from all the other analyzed populations, since its karyotype presented NORs in the chromosome pairs 1,3,4 and 10 (and sometimes also in chromosome 5), and several pericentromeric C-bands. A NOR-site in chromosome 9 characterized three populations from the northeastern region of Brazil. Interestingly, the P. cuvieri populations located in opposite extremes of the geographic distribution had, as a fixed condition, the presence of NORs in 8q...

En 1980, Marco Antonio Serna colectó dos ejemplares de una inusual rana de cristal en el noroccidente del Departamento de Antioquia, Colombia. Dichos ejemplares exhibían algunas características sobresalientes entre las cuales llamó la atención su gran tamaño. Aparentemente solo uno de estos ejemplares (el holotipo hembra) fue enviado para su identificación a Juan A. Rivero, quien la describió bajo el nombre de Centrolenella megistra (Rivero, 1985). Sin embargo, escasa información concerniente a la especie ha sido reportada en la literatura desde la descripción original, más allá de su re-asignación genérica. En este trabajo, presentamos una redescripción de esta especie, con una adecuada delimitación de sus características, asignamos un neotipo,...
