On the Identity of Sphaenorhynchus platycephalus (Werner, 1894) (Anura: Hylidae)
Sphaenorhynchus platycephalus was briefly described on the basis of a single specimen, with only "S-Amerika" as its locality. Although it has been regarded as a distinct species, compelling evidence is lacking. A comparison of all currently described species of Sphaenorhynchus, including type specimens of several species, allowed us to provide morphological evidence that S. platycephalus and S. orophilus are conspecific, with S. orophilus being a junior synonym of S. platycephalus.Fil: de Araujo Vieira, Katyuscia.

Hábitos alimenticios de la rana bromélicola Phyllodytes edelmoi Peixoto, Caramaschi & Freire, 2003 (Anura: Hylidae) del Estado de Alagoas, Noreste de Brasil
El género de hílidos Phyllodytes está compuesto por 12 especies distribuidas en el este de Brasil y conocidas por habitar estrictamente bromeliáceas. En este estudio se exploran los hábitos alimenticios de P. edelmoi y se testea la selectividad de las presas por la especie comparando las presas encontradas en los estómagos con la disponibilidad de presas en las bromelias. Nuestros resultados muestran que P. edelmoi consume grandes cantidades de hormigas a lo largo del año, por lo que podría considerarse una especie "especializada en hormigas". Este comportamiento alimenticio especializado podría ser considerado una sinapomorfia para el género Phyllodytes.The hylid frog genus Phyllodytes comprised 12 species distributed in eastern Brazil and knownto strictly inhabit inside bromeliads. In this study, we explore the feeding habits of P. edelmoiand test the prey selectivity of the species by comparing the prey items in the stomachs contentswith the availability of preys in bromeliads. Our results show that P. edelmoi consumes highamounts of ants along the year, and therefore it could be considered an ?ant specialist? species.This specialist feeding behaviour could be considered a synapomorphy of the genus Phyllodytes.Fil: Araujo-Vieira, Katyuscia.

Larval anatomy of Dendropsophus decipiens (A. Lutz 1925) (Anura: Hylidae: Dendropsophini) with considerations to larvae of this genus
The Dendropsophus decipiens clade comprises four species: D. berthalutzae, D. decipiens, D. haddadi, and D. oliveirai. Tadpoles of these species were described, but data on their internal morphology are lacking. We provide the first description of the buccopharyngeal anatomy, chondrocranial morphology, and cranial, hyoid and hyobranchial musculature of the tadpole of D. decipiens. Larvae of D. decipiens are characterized by the absence of lingual papillae, presence of fan-like papilla on the buccal floor, presence of a single-element suprarostral cartilage, presence of a small triangular process at the basis of the processus muscularis, m. levator mandibulae lateralis inserted on the nasal sac, and m. subarcualis rectus II-IV with a single, continuous slip. Tadpoles are likely macrophagous, although not as specialized as those of other species of the genus, suggesting some degree of diversification on the feeding habits within Dendropsophus.Fil: Dias, Pedro H.

A neotype for Hyla x-signata Spix, 1824 (Amphibia, Anura, Hylidae)
The uncertain identity of Hyla x-signata Spix, 1824 has been a pervasive problem in the taxonomy of the genus Scinax. A species supposedly distributed from northeastern Brazil northwards to Colombia and Venezuela, described in a few lines without much information and with an accompanying figure, and its type specimen lost during World War II, combined to produce a curious situation. Twenty-one of the 39 species of the S. ruber Clade described in the last 50 years were considered to require a diagnosis from S. x-signatus by their authors. In most cases these had no other alternative than to gather information about this species from indirect sources, frequently pointing out the problems associated with its uncertain identity. In this paper, we review the taxonomic history of Hyla x-signata, designate a neotype, provide a redescription including advertisement call and sequence data, and diagnose it from all other species of the S. ruber Clade.Fil: de Araujo Vieira, Katyuscia.

Revisão da distribuição geográfica de Sphaenorhynchus prasinus Bokermann, 1973 (Anura: Hylidae) no Estado de Alagoas, nordeste do Brasil
Sphaenorhynchus prasinus is a neotropical small greenish treefrog characterized by a canthal black line, dermal folds on forearms and tarsi, dermal fold on elbow and round calcar appendage, and a white dermal flap with round lateral margins on the subcloacal region. Its geographic distribution comprises southeastern and northeastern of Brazil. In this note, we rectify the previous records of S. prasinus and restablish the occurrence of the species for the state of Alagoas, northeastern Brazil based on new findings.Sphaenorhynchus prasinus é um anuro neotropical arborícola caracterizado por apresentar uma linha negra na região cantal, pregas dérmicas nos antebraços, cotovelos e tarsos, apêndices calcâneos arredondados e região subcloacal com uma aba dérmica branca e margens laterais circulares. Sua distribuição geográfica abrange o sudeste e nordeste do Brasil. No presente trabalho, nós corrigimos informações prévias sobre o registro de S. prasinus e estabelecemos a ocorrência da espécie para o Estado de Alagoas, nordeste do Brasil, a partir de novos achados.Fil: de Araujo Vieira, Katyuscia.

On the Monophyly and Relationships of Several Genera of Hylini (Anura: Hylidae: Hylinae), with Comments on Recent Taxonomic Changes in Hylids
We present a molecular phylogenetic analysis of the hylid tribe Hylini, with the goals of testing the monophyly of the genera Duellmanohyla, Isthmohyla, and Ptychohyla and providing a discussion on the monophyly of Bromeliohyla, Charadrahyla, Ecnomiohyla, Exerodonta, Megastomatohyla, and Sarcohyla. Our results indicate the paraphyly of Ptychohyla, with Bromeliohyla and Duellmanohyla nested within it, and, as in previous analyses, the paraphyly of Duellmanohyla (due to Ptychohyla legleri and P. salvadorensis being nested within it). To resolve this situation, we restrict the contents of Ptychohyla, redelimit those of Duellmanohyla and Bromeliohyla, and erect two new genera, one to include the former Ptychohyla panchoi and P. spinipollex, and the other for the former Ptychohyla acrochorda, P. sanctaecrucis, P. zoque, and tentatively, P. erythromma. Exerodonta as currently defined is not monophyletic, inasmuch as Exerodonta juanitae is nested within Charadrahyla. Consequently, we transfer this species and, tentatively, E. pinorum to Charadrahyla. Also, we discuss some possible taxonomic problems within Exerodonta. Our results indicate that Isthmohyla is polyphyletic, the bromeliad-dwelling Isthmohyla melacaena being the sister taxon of our only exemplar of Bromeliohyla, B. bromeliacia. For this reason, we transfer I. melacaena to Bromeliohyla, rendering Isthmohyla monophyletic. The former Isthmohyla pictipes Group is shown to be paraphyletic due to having the non-monophyletic I. pseudopuma Group within it. Accordingly, we recognize a redelimited I. pseudopuma Group (contents: I. infucata and I. pseudopuma), an I. zeteki Group (contents: I. picadoi and I. zeteki), and a newly defined I. tica Group (contents: I. angustilineata, I. calypsa, I. debilis, I. graceae, I. lancasteri, I. pictipes, I. tica, I. rivularis, and, tentatively, I. insolita and I. xanthosticta). The three groups of Isthmohyla are supported by molecular evidence with jackknife support values > 90%, and two of them by putative morphological synapomorphies. We discuss the recognition of Dryophytes, Hyliola, Rheohyla, and Sarcohyla and whether it is useful to recognize Anotheca, Diaglena, and Triprion as three distinct, monotypic genera. Finally, we discuss a recent taxonomic proposal involving changes in rank and from ranked to unranked names in hylids that overall we consider to have been poorly justified and only superficially discussed.Fil: Faivovich, Julián.

Treefrog diversity in the Neotropics: phylogenetic relationships of Scinax (Anura: Hylidae)
Scinax is the most species-rich genus of neotropical treefrogs, with more than 115 known species distributed into two large clades: the S. ruber and S. catharinae clades. The S. catharinae clade includes 47 species placed in the S. perpusillus and S. catharinae groups, whereas the S. ruber clade is composed of 71 species, 12 of which are included in two groups of species: S. rostratus and S. uruguayus groups, remaining more than 50 unsigned group species. Although some studies have addressed phylogenetically the genus using few representatives, the phylogenetic relationships among their species remain poorly understood. In order to testing the monophyly of the genus, clades, and species groups currently known and exploring their interrelationships, we performed a phylogenetic analysis of total evidence including sequences of four mitochondrial and six nuclear genes, supplemented with sequences from GenBank and 155 phenotypic characters. It was included 110 of the 118 species currently known of Scinax and several new species. Most species are represented by several specimens, and more than 42% are represented by topotypes. As a result of this analysis, the genus Scinax is partitioned into four genera. Scinax is restricted to the former Scinax ruber group and is divided in nine species groups to facilitate its taxonomic study, only few species remain unassigned to any group. Julianus, originally composed of the S. uruguayus group species, is redefined to avoid the paraphyly of Scinax. Ololygon is recognized for most species of the former S. catharinae clade, and a new genus is described to avoid the potential paraphyly of Ololygon as was recognized recently by some authors. All species groups are discussed, diagnosed and characterized, in many cases presenting phenotypic synapomorphies. Based on the resulting phylogenetic hypothesis, the evolution of several character systems and the diversity of this group are discussed.Scinax is the most species-rich genus of neotropical treefrogs, with more than 115 known species distributed into two large clades: the S. ruber and S. catharinae clades.

Previous issue date: 2010-08-17O g?nero de hil?deos Sphaenorhynchus ? atualmente composto por 14 esp?cies, tr?s delas com distribui??es associadas ? Bacia Amaz?nica, dez ? Floresta Atl?ntica e uma com distribui??o incerta. Apesar de algumas sinapomorfias morfol?gicas terem sido propostas para Sphaenorhynchus, evid?ncias convincentes de monofilia faltam para este g?nero, e os relacionamentos entre suas esp?cies s?o virtualmente desconhecidos. Com os objetivos de (1) testar a monofilia de Sphaenorhynchus; (2) testar as rela??es entre as suas esp?cies; e (3) testar no contexto filogen?tico a evolu??o da pedomorfose e s?tios de oviposi??o, eu realizei uma an?lise filogen?tica baseada em 166 caracteres fenot?picos tomados de 11 esp?cies de Sphaenorhynchus e 12 taxa do grupo externo, e sequ?ncias de DNA dos genes 12S, tRNA valine, 16S e citocromo b para oito representantes de Sphaenorhynchus e 22 taxa do grupo externo. Na an?lise de evid?ncia total a monofilia de Sphaenorhynchus foi suportada por um valor de Goodman-Bremer (GB) de 20 e diagnosticada por 24 transforma??es fenot?picas e 62 genot?picas, com S. pauloalvini sendo a esp?cie irm? de todas as outras esp?cies do g?nero. Sphaenorhynchus carneus forma um clado junto ?s demais esp?cies do g?nero (excluindo S. pauloalvini) suportado por GB de 17 e 20 transforma??es fenot?picas. As duas esp?cies amaz?nicas (S. lacteus e S. dorisae) formam um clado posicionado entre as esp?cies de Floresta Atl?ntica. Sphaenorhynchus prasinus ? a esp?cie irm? do clado formado por S. palustris, S. bromelicola, S. orophilus, S. surdus e S. caramaschii. O relacionamento entre estas esp?cies n?o ? definido na an?lise de evid?ncia total. No entanto, na an?lise de apenas os dados fenot?picos S. palustris aparece como esp?cie irm? das outras esp?cies desse clado, e S. bromelicola como esp?cie irm? do clado formado por S. orophilus, S. surdus e S. caramaschii. Na an?lise de dados fenot?picos S. surdus ? agrupado com S. caramaschii, mas na an?lise de dados genot?picos cai junto a S. orophilus. A evolu??o da pedomorfose em Sphaenorhynchus ? amb?gua. A inclus?o de S. botocudo e S. mirim e a resolu??o da ambiguidade no posicionamento de S. palustris e S. bromelicola s?o necess?rias para o melhor entendimento da evolu??o deste car?ter dentro do g?nero. A deposi??o de ovos na ?gua ? um estado ancestral em rela??o ? deposi??o de ovos nas folhas, que pode ser uma sinapomorfia para Sphaenorhynchus ou ter evolu?do independentemente em S. carneus e S. pauloalvini, com a deposi??o de ovos em brom?lias sendo facultativa para S. surdus
