Assessing the taxonomic status of tropical frogs through bioacoustics: geographical variation in the advertisement calls in the Eleutherodactylus discoidalis species group (Anura)

Comparisons of advertisement calls of anurans can be used to determine intra- and interspecific differences or affinities. Described from midwestern Brazil, Pseudopaludicola mystacalis is widely distributed and abundant in major open Brazilian ecosystems. However, researchers frequently fail to determine the true taxonomic status of some of these populations and attribute them to unidentified or misidentified species. Herein, we employ morphological and bioacoustic data to reassess the distribution range and to evaluate intraspecific variation in P. mystacalis based on specimens from fifteen localities and seven Brazilian states. We also reassess the distribution and taxonomic status of Pseudopaludicola serrana, herein considered as a junior synonym of P. murundu based on morphology, bioacoustics, and molecular data.

We reassessed the taxonomic status of the species in the Atractus collaris complex (A. alphonsehogei, A. collaris, A. limitaneus, and A. gaigeae) on the basis of congruence between quantitative and qualitative morphological characters (meristic, morphometric, color pattern, hemipenis, and scale microdematoglyphics) along its wide geographical distribution. Our results support the recognition of three species with apparently fixed diagnostic characters. We propose the synonymization of Atractus limitaneus with A. collaris based on the wide overlap of all morphological character systems here analyzed, as well as on the basis of examination of the holotype and two topotypes of A. limitaneus. Finally, we discuss the geographical variation and morphological distinction of A. alphonsehogei, A. collaris and A. gaigeae. Furthermore, we provide a dichotomous key for all recognized species in the A. collaris species group.

A New Species

The Asian frog genus Megophrys is a diverse group of morphologically conserved, forest-dwelling frogs. The genus harbours highly localised species diversification and new species continue to be described on a regular basis. We examined the taxonomic status of a population of Megophrys frogs from the Hoang Lien Range in northern Vietnam and southern China previously identified as M. kuatunensis (subgenus Panophrys). Preliminary phylogenetic analyses using a fragment of 16S rDNA places the species in question within the Megophrys (subgenus Panophrys) species group, a primarily Chinese radiation within the genus. On the basis of morphological, molecular and bioacoustic data, we conclude that this population does not represent M. kuatunensis, or any known species in the genus. We herein describe this species of Megophrys as new. Known only from Sa Pa District, Lao Cai Province in Vietnam and Jinping County, Yunnan Province in China, the new species is likely to be threatened by ongoing deforestation in the region. We provide an updated species description of M. kuatunensis based on type specimens, and suggest that M. kuatunensis is likely to be restricted to eastern China.

AbstractTo evaluate the taxonomic status of the races of the graceful crag lizard, Pseudocordylus capensis, geographical variation in 44 external morphological characters was determined, using 97 specimens from 31 localities. Two different epiphenotypes predominate in the northern and southwestern parts of the distribution range. These epiphenotypes are, however, connected by a continuum of variation. It is therefore suggested that the recognition of races be abandoned in the formal taxonomy. Several new distribution records for the species are provided.

Definition Of

Anomaloglossus is a species-rich genus of frogs endemic to the Guiana Shield that still harbors several unnamed species. Within the A. stepheni species group (which includes four valid nominal species), A. baeobatrachus has an uncertain taxonomic status, notably because the holotype was an unvouchered specimen depicted in a popular journal. Another member of this group, A. leopardus, was only superficially described, lacking information on the sex of specimens in the type series and on advertisement call. Therefore, these two taxa need clarifications in order to allow the description of the extant undescribed species. In this paper, we redescribe A. baeobatrachus based on newly collected material from the species type locality and provide information about its reproductive ecology. We also provide an amended definition of A. leopardus using newly collected material from its type locality. These two species form a clade along with a third species from the Eastern Guiana Shield, which is also described herein. The reproductive biology of A. baeobatrachus and A. stepheni is very similar. Both species have endotrophic and nidicolous tadpoles, despite being distantly related, suggesting independent evolution of this breeding mode. The new species and A. leopardus, on the other hand, have exotrophic tadpoles.

Marine Gastrotricha, both Macrodasyida and Chaetonotida, are the subject of an analytic review, citing taxonomic status of names, authorships of taxa, and those responsible for changes, in accordance with the International Code of Zoological Nomenclature, 4 th ed. (1999). Notes are included with regard to taxonomic usage so as to guide workers in the future. Among the proposed novelties are: within Macrodasyida, to restrict the family Lepidodasyidae Remane, 1927 to the genus Lepidodasys Remane, 1926, and to establish a new family, Cephalodasyidae with Cephalodasys Remane, 1926 as its type-species to house the remaining genera and species that have been contained in the polyphyletic family Lepidodasyidae. Hemidasys agaso Claparède, 1867 is considered extinct, and the new name Tetranchyroderma antenniphorum is proposed for Tetranchyroderma antennatum Luporini, Magagnini & Tongiorgi, 1973; in addition, five species are here considered to be species inquirendae: Dactylopodola weilli d'Hondt, 1965, Paradasys nipponensis Sudzuki, 1976, Macrodasys indicus Kutty & Nair, 1969. Tetranchyroderma forceps d’Hondt & Balsamo, 2009 and Turbanella plana (Giard, 1904b). Among Chaetonotida: the Xenotrichula velox-species group Ruppert, 1979 and the Xenotrichula intermedia-species group Ruppert, 1979 were given each the rank of subgenus. Chaetonotus pleuracanthus Remane, 1926 is rejected as a synonym for Chaetonotus marinus Giard, 1904; Chaetonotus somniculosus Mock, 1979 is transferred to the genus Halichaetonotus, the new name Halichaetonotus euromarinus is proposed for Halichaetonotus spinosus Mock, 1979, and Xenotrichula carolinensis Ruppert, 1979 is re-established. Heteroxenotrichula variocirrata d'Hondt, 1966 is here considered to be species inquirenda.

Qualitative Analyses

The taxonomic status of Dipsas albifrons is revised and geographic variation of external morphology and hemipenis are described. Multivariate analyses suggest that the pattern of geographical variation is correlated with gap sampling, probably indicating a northernward cline in segmental counts (mainly ventral and subcaudal scales). Quantitative and qualitative analyses reveal that the island population (Dipsas albifrons cavalheiroi) is not divergent from mainland populations and, herein, is considered a junior synonymy of Dipsas albifrons. A lectotype of Dipsas albifrons is designated.

AbstractWe investigated genetic diversity and phylogeny of all water strider species assigned to the Aquarius paludum species group on basis of 425 bp DNA sequence data from the mitochondrial gene encoding cytochrome oxidase subunit I (COI). Parsimony analyses and genetic distances confirmed the taxonomic status of the two recently described species Aquarius lili Polhemus & Polhemus, 1994 from Timor and A. philippinensis Zettel & Ruiz, 2003 from the Philippines as being separate from the widespread Oriental A. adelaidis (Dohrn, 1860). Molecular clock estimates suggest that the disjunct zoogeographical pattern among the three species is due to a Pliocene/Pleistocene long-range dispersal, rather than a Mesozoic vicariance event as previously suggested. However, when we superimposed the disjunct distribution of Southern Hemisphere representatives of the paludum-group onto their phylogenetic relationship, the pattern indicated vicariance events following the break-up of Gondwana.
