Description of a new frog of the genus Hyla from Suriname

While in Suriname during June 1964, I had the opportunity of collecting a series of a species of Hyla that seems to be undescribed. It seems appropriate that this species be known as Hyla boesemani sp. nov. (fig. 1) Diagnosis. — A small Hyla with vomerine tooth patches close together or contiguous; with just a trace of web between the fingers; fourth toe webbed to the base of the penultimate phalanx; a small but well-developed patagium; a very distinct skin fold across chest. It has a dorsal pattern of scattered light spots, a distinct, narrow, postocular dark stripe, and lacks a pattern on the thigh although the latter has a small amount of uniformly distributed pigment present. This species is perhaps most easily confused with the members of the Hyla leucophyllata-group because of its pale, unpatterned thighs. It differs from these, though, in the fact that its thighs are gray rather than pink in life and in that in preservative the thigh, although without a pattern, is covered with a rather uniform gray pigmentation rather than being pigmentless as are those of the members of the leucophyllata-group. Holotype. — Rijksmuseum van Natuurlijke Historie 12601, adult male, collected near Zanderij, Suriname District, Suriname, on June 16, 1964, by Coleman J. Goin and D. C. Geijskes. Paratypes. — Fourteen, all adult males, as follows: Rijksmuseum van Natuurlijke Historie (RMNH) 12602, 12603; Florida State Museum 22367; and Coleman J. Goin collection (CJG) 2408, 2409, 2414; from Zanderij, Suriname Distict, Suriname. American Museum of Natural History A75555; British Museum (Natural History) 1966.26; Carnegie Museum 41595; Mu

A total evidence analysis of the phylogeny of hatchet-faced treefrogs (Anura: Hylidae: Sphaenorhynchus)

The Neotropical hylid genus Sphaenorhynchus includes 15 species of small, greenish treefrogs widespread in the Amazon and Orinoco basins, and in the Atlantic Forest of Brazil. Although some studies have addressed the phylogenetic relationships of the genus with other hylids using a few exemplar species, its internal relationships remain poorly understood. In order to test its monophyly and the relationships among its species, we performed a total evidence phylogenetic analysis of sequences of three mitochondrial and three nuclear genes, and 193 phenotypic characters from all species of Sphaenorhynchus. Our results support the monophyly of Sphaenorhynchus with molecular and phenotypic evidence, with S. pauloalvini as the earliest diverging taxon, followed by S. carneus, as the sister taxon of all remaining species of the genus. We recognize three species groups in Sphaenorhynchus (the S. lacteus, S. planicola and S. platycephalus groups), to facilitate its taxonomic study; only three species (S. carneus, S. pauloalvini and S. prasinus) remain unassigned to any group. Sequence data were not available for only two species (S. bromelicola and S. palustris) for which we scored phenotypic data; wildcard behaviour was detected only in S. bromelicola nested inside the S. platycephalus group. On the basis of the resulting phylogenetic hypothesis, we discuss the evolution of oviposition site and a number of phenotypic characters that could be associated with heterochronic events in the evolutionary history of this group.Fil: de Araujo Vieira, Katyuscia.

O status taxonômico de Hyla cochranae Mertens e recaracterização de Aplastodiscus A. Lutz (Anura, Hylidae) The taxonomic status of the Hyla cochranae Mertens and recharacterization of Aplastodiscus A. Lutz (Anura, Hylidae)

<abstract language="eng">Hyla cochranae Mertens, 1952 is revalidated and the description of the tadpole and vocalization is provided. Based on external morphology, the genus Aplastodiscus A. Lutz, 1950 is recharacterized and a redescription of A. perviridis A. Lutz, 1950 is given. New data on geographical distribution and biology of both species are provided
