BROWN, JASON L., EVAN TWOMEY, ADOLFO AMÉZQUITA, MOISÉS BARBOSA DE SOUZA, JANALEE P. CALDWELL, STEFAN LÖTTERS, RUDOLF VON MAY et al. „A taxonomic revision of the Neotropical poison frog genus Ranitomeya (Amphibia: Dendrobatidae)“. Zootaxa 3083, Nr. 1 (28.10.2011): 1. http://dx.doi.org/10.11646/zootaxa.3083.1.1.

Annotation:
The Neotropical poison frog genus Ranitomeya is revised, resulting in one new genus, one new species, five synonymies and one species classified as nomen dubium. We present an expanded molecular phylogeny that contains 235 terminals, 104 of which are new to this study. Notable additions to this phylogeny include seven of the 12 species in the minuta group, 15 Ranitomeya amazonica, 20 R. lamasi, two R. sirensis, 30 R. ventrimaculata and seven R. uakarii. Previous researchers have long recognized two distinct, reciprocally monophyletic species groups contained within Ranitomeya, sensu Grant et al. 2006: the ventrimaculata group, which is distributed throughout much of the Amazon, and the minuta group of the northern Andes and Central America. We restrict Ranitomeya to the former group and erect a new genus, Andinobates Twomey, Brown, Amézquita & Mejía-Vargas gen. nov., for members of the minuta group. Other major taxonomic results of the current revision include the following: (i) A new species, Ranitomeya toraro Brown, Caldwell, Twomey, Melo-Sampaio & Souza sp. nov., is described from western Brazil. This species has long been referred to as R. ventrimaculata but new morphological and phylogenetic data place it sister to R. defleri. (ii) Examination of the holotype of R. ventrimaculata revealed that this specimen is in fact a member of what is currently referred to as R. duellmani, therefore, Dendrobates duellmani Schulte 1999 is considered herein a junior synonym of D. ventrimaculatus Shreve 1935 (= R. ventrimaculata). (iii) For the frogs that were being called R. ventrimaculata prior to this revision, the oldest available and therefore applicable name is R. variabilis. Whereas previous definitions of R. variabilis were restricted to spotted highland frogs near Tarapoto, Peru, our data suggest that this color morph is conspecific with lowland striped counterparts. Therefore, the definition of R. variabilis is greatly expanded to include most frogs which were (prior to this revision) referred to as R. ventrimaculata. (iv) Phylogenetic and bioacoustic evidence support the retention of R. amazonica as a valid species related to R. variabilis as defined in this paper. Based on phylogenetic data, R. amazonica appears to be distributed throughout much of the lower Amazon, as far east as French Guiana and the Amazon Delta and as far west as Iquitos, Peru. (v) Behavioral and morphological data, as well as phylogenetic data which includes topotypic material of R. sirensis and numerous samples of R. lamasi, suggest that the names sirensis, lamasi and biolat are applicable to a single, widespread species that displays considerable morphological variation throughout its range. The oldest available name for this group is sirensis Aichinger; therefore, we expand the definition of R. sirensis. (vi) Ranitomeya ignea and R. intermedia, elevated to the species status in a previous revision, are placed as junior synonyms of R. reticulata and R. imitator, respectively. (vii) Ranitomeya rubrocephala is designated as nomen dubium. In addition to taxonomic changes, this revision includes the following: (i) Explicit definitions of species groups that are consistent with our proposed taxonomy. (ii) A comprehensive dichotomous key for identification of ‘small’ aposematic poison frogs of South and Central America. (iii) Detailed distribution maps of all Ranitomeya species, including unpublished localities for most species. In some cases, these records result in substantial range extensions (e.g., R. uakarii, R. fantastica). (iv) Tadpole descriptions for R. amazonica, R. flavovittata, R. imitator, R. toraro sp. nov., R. uakarii and R. variabilis; plus a summary of tadpole morphological data for Andinobates and Ranitomeya species. (v) A summary of call data on most members of Andinobates and Ranitomeya, including call data of several species that have not been published before. (vi) A discussion on the continued impacts of the pet trade on poison frogs (vii) A discussion on several cases of potential Müllerian mimicry within the genus Ranitomeya. We also give opinions regarding the current debate on recent taxonomic changes and the use of the name Ranitomeya.

We examined a large collection (n = 132) of tree frogs, hitherto identified as Litoria gracilenta, from various localities in New Guinea and compared them with Litoria gracilenta from Queensland and with the recently described Litoria elkeae from far west New Guinea. We found that the frogs in question were neither L. gracilenta nor L. elkeae but comprised two distinct taxa described herein as new species.We call attention to the problems of performing statistical analysis on measurements of soft-bodied organisms and consider that the conclusions reached in this analysis are both conservative and realistic.

Annotation:
The extent of development of digital adhesive toe-pads in sympatric species of microhylid frogs, Cophixalus and Sphenophryne, correlates with the degree of arboreality exhibited by the species. The same basic structures and cell types are found in the toe-pads of these microhylid frogs as are found in other arboreal and semi- arboreal frogs of many diverse evolutionary lineages. A variety of types of cell surface, with unknown functional significance but potential systematic use, are found on the feet of these frogs. Allometric increase in adhesive-pad area in larger species is by widening of the toe-pad, as opposed to acquisition of accessory pads as in some hylid tree frogs.

Annotation:
Abstract:Major tropical rivers have been suggested to be important dispersal barriers that increase the beta diversity of animal communities in lowland rain forests. We tested this hypothesis using assemblages of frogs in the floodplains of the Sepik River, a major river system in Papua New Guinea. We surveyed frogs at five sites within a continuous 150 × 500-km area of lowland rain forest bisected by the Sepik, using standardized visual and auditory survey techniques. We documented 769 frogs from 44 species. The similarity in species composition decreased with logarithm of geographical distance between the sites, which ranged from 82 to 465 km. The similarity decay did not depend on whether or not the compared sites were separated by the Sepik River or whether the species were aquatic or terrestrial breeders. Likewise, a DCA ordination of frog assemblages did not show separation of sites by the river as a significant factor explaining their composition. Our results suggest that even major rivers, such as the Sepik, may not act as dispersal barriers. Rivers may not limit the distribution of frogs and therefore have a limited effect on determining frog species abundance and assemblage structure in rain forests.

Annotation:
Oreophryne presently represents the second-most-diverse genus of microhylid frogs, with 57 named species, most occurring on New Guinea and its satellite islands. Nonetheless, a diversity of species remains to be described. Using morphological, color-pattern, and advertisement-call data, I describe ten new species of Oreophryne from the Papuan Peninsula of New Guinea and adjacent islands, which together form the East Papuan Composite Terrane. All but two of these species can be placed into two species groups based on call type. I refer to these species groups as the O. anser group and the O. equus group, both being based on species described herein. Members of the O. anser group produce calls reminiscent of a goose honk, whereas members of the O. equus group produce calls reminiscent of a horse’s whinny. Description of three new species in the O. anser group requires me to first rediagnose O. loriae, which has previously been interpreted as including the frogs named herein as O. anser sp. nov. The honk call type has not previously been reported within Oreophryne, and the whinny call may be novel as well, although it is possibly derived from other New Guinean species having calls consisting of a slower series of peeps. Based on their unique call types, I hypothesize that both species groups are monophyletic. If true, each would appear endemic to the East Papuan Composite Terrane. Only five additional species of Oreophryne are known from this region that do not belong to one or the other of these two species groups; hence, these newly identified species groups represent the majority of diversity in Oreophryne from the Papuan Peninsula and its satellite islands.

Annotation:
I examined a collection of approximately 230 frogs referable to the genus Albericus on account of four synapomorphies (long fifth toes, short legs, absence of clavicle and origin of the mandibular depressor muscles). Morphometric analysis coupled with call characteristics suggests three or four distinct clades within the genus. The status of Albericus variegatus is examined and found to be equivocal. Two recognised species (A. darlingtoni and A. tuberculus) are redefined and eight new species are described. I comment on several other specimens that cannot be accommodated within those species described.

Annotation:
Cophixalus represents the most diverse genus of microhylid frogs. Within this group I show that two recently describedspecies are in fact synonyms of species described in the 19th Century. Proper recognition of one of these has been hinderedby the poor state of the syntypes and confused information presented in earlier literature. The second species was simplynot diagnosed against other members of the genus. I also describe five new species: one of these is known only from asingle specimen from far western New Guinea, two occupy the Papuan Peninsula in the east of that island, and two arerestricted to Woodlark Island off the southeastern tip of New Guinea. One of these new species had earlier been mis-iden-tified as C. pipilans, requiring me to herein provide a corrected comparison of features that distinguishes C. desticans fromC. pipilans. These taxonomic changes bring the number of Cophixalus species to 61, of which 42 inhabit New Guinea andimmediately adjacent islands. But much of this region remains poorly surveyed, and, undoubtedly, many additional spe-cies remain to be described. I provide the first dichotomous key for the Papuan members of this genus, which should facilitate description of additional species.

Annotation:
New Guinea is home to the world’s most diverse insular frog biota, but only a small number of taxa have been included in genetically informed assessments of species diversity. Here we describe two new species of New Guinea treefrog in the genus Litoria that were first flagged during assessments of genetic diversity (DNA barcoding) and are currently only known from the holotypes. Litoria pterodactyla sp. nov. is a large green species in the Litoria graminea species complex from hill forests in Western Province, Papua New Guinea and is the third member of this group known from south of the Central Cordillera. Litoria vivissimia sp. nov. is a small, spike-nosed species from mid-montane forests on the Central Cordillera. It is morphologically very similar to Litoria pronimia, but occurs nearly 1000 m higher than any known locality for that species. More extensive genetically informed assessment of diversity in New Guinea frogs seems certain to reveal many more as-yet-unrecognised taxa in complexes of morphologically similar species.

Annotation:
Australia and New Guinea (together referred to as Sahul) were linked by land for much of the late Tertiary and share many biotic elements. However, New Guinea is dominated by rainforest, and northern Australia by savannah. Resolving patterns of biotic interchange between these two regions is critical to understanding the expansion and contraction of both habitat types. The green tree frog (Litoria caerulea) has a vast range across northern and eastern Australia and New Guinea. An assessment of mitochondrial and morphological diversity in this nominal taxon in New Guinea reveals two taxa. True Litoria caerulea occurs in disjunct savannahs of the Trans-Fly, Central Province and across northern Australia, with very low genetic divergence, implying late Pleistocene connectivity. A previously unrecognised taxon is endemic to New Guinea and widespread in lowland swampy rainforest. Date estimates for the divergence of the new species suggest Pliocene connectivity across lowland tropical habitats of northern Australia and New Guinea. In contrast, the new species shows shallow phylogeographic structuring across the central mountains of New Guinea, implying recent dispersal between the northern and southern lowlands. These results emphasise that the extent and connectivity of lowland rainforest and savannah environments across northern Australia and southern New Guinea have undergone profound shifts since the late Pliocene. http://zoobank.org/urn:lsid:zoobank.org:pub:A577A415-0B71-4663-B4C1-7271B97298CD

Litoria graminea is a large green canopy-dwelling frog originally described from a single specimen from an unknown locality in Papua New Guinea. We demonstrate that this species as currently recognised contains at least three distinct taxa. We restrict the name L. graminea to a population of animals occurring south of New Guinea’s main cordillera and describe two new species of large green arboreal frogs, one from the Kikori River Basin (Southern Highlands and Gulf Province) and one from the Huon Peninsula (Morobe Province). The two new species can be distinguished from each other by differences in iris and sclera colouration, and both can be distinguished from L. graminea by their narrower heads, different iris colouration and by their small round (vs elongate) nuptial pads.

AimsMountain ranges in the tropics are characterised by high levels of localised endemism, often-aberrant evolutionary trajectories, and some of the world’s most diverse regional biotas. Here we investigate the evolution of montane endemism, ecology and body size in a clade of direct-developing frogs (Choerophryne,Microhylidae) from New Guinea.MethodsPhylogenetic relationships were estimated from a mitochondrial molecular dataset using Bayesian and maximum likelihood approaches. Ancestral state reconstruction was used to infer the evolution of elevational distribution, ecology (indexed by male calling height), and body size, and phylogenetically corrected regression was employed to examine the relationships between these three traits.ResultsWe obtained strong support for a monophyletic lineage comprising the majority of taxa sampled. Within this clade we identified one subclade that appears to have diversified primarily in montane habitats of the Central Cordillera (>1,000 m a.s.l.), with subsequent dispersal to isolated North Papuan Mountains. A second subclade (characterised by moderately to very elongated snouts) appears to have diversified primarily in hill forests (<1,000 m a.s.l.), with inferred independent upwards colonisations of isolated montane habitats, especially in isolated North Papuan Mountains. We found no clear relationship between extremely small body size (adult SVL less than 15 mm) and elevation, but a stronger relationship with ecology—smaller species tend to be more terrestrial.ConclusionsOrogeny and climatic oscillations have interacted to generate high montane biodiversity in New Guinea via both localised diversification within montane habitats (centric endemism) and periodic dispersal across lowland regions (eccentric endemism). The correlation between extreme miniaturisation and terrestrial habits reflects a general trend in frogs, suggesting that ecological or physiological constraints limit niche usage by miniaturised frogs, even in extremely wet environments such as tropical mountains.

Embryonic development in fifteen Australopapuan microhylid frogs of the genera Austrochaperina, Cophixalus and Oreophryne is described. These frogs have direct development during which the embryo develops to a minute froglet within the jelly capsule. Development of the operculum, presence of external gills, tail structure, gut development and timing of forelimb emergence are described and compared with the direct-developing eleutherodactylid Eleutherodactylus coqui from Puerto Rico and three Australian myobatrachid genera with direct development (Arenophryne, Metacrinia and Myobatrachus). We comment on those differences that likely reflect examples of convergent and divergent evolution and heterochrony.

AbstractThe karyotypes of three platymantine frogs, Platymantis hazelae and P. dorsalis from Philippines and P. papuensis from Papua New Guinea, were described and compared. P. hazelae has 2n = 26 chromosomes consisting of five large and eight small pairs, as in many other species of Ranidae. The karyotypes of P. dorsalis (2n = 20) and P. papuensis (2n = 22) may be derived from the basic karyotype of 2n = 26. Simple fusions and pericentric inversions explain the karyotypic relationships between P. hazelae and P. papuensis, while the karyotype of P. dorsalis seems to have resulted from more complicated chromosome rearrangements.

Annotation:
Studies have suggested that predation by spiders may be an important force regulating life history in neotropical frogs and lizards, but detailed descriptions of predator-prey relationships are few. Here we describe novel observations where spiders contributed to the mortality of frogs and lizards in northeastern Costa Rica, and we corrected or clarified three identification errors of spiders from the literature. The most frequently observed predators were wandering spiders (Ctenidae), which seem to be generalist predators on frogs and lizards. An orb-weaver spider (Araneidae) also contributed to frog mortality, likely after the frog became entangled in the spider’s web. More detailed studies are needed to elucidate the role that spider predation contributes to frog and lizard demography in neotropical forests.

Mixophyes are large ground-dwelling myobatrachid frogs from eastern Australia and New Guinea. We use analyses of allozyme frequencies, nucleotide sequences of mitochondrial DNA and morphology to define species boundaries in Mixophyes from the Wet Tropics World Heritage Area of northern Queensland. The molecular analyses identify a minimum of three species in the region. Morphometric and meristic analyses corroborate these distinctions. The existence of two of these species was not previously suspected, and they are formally described herein.

Annotation:
The Fringed Tree Frog (Litoria eucnemis) is closely related to the Tree Frog Litoria genimaculata. Both species are found in northern Australia and New Guinea. We have reported that the major antibiotic peptide of L. genimaculata is maculatin 1.1 which has the sequence GLFGVLAKVAAHVVPAIEHF-NH2, and that this basic peptide is different from the hinged caerin 1 peptides (e.g. caerin 1.1, from Litoria splendida and other green tree frogs, which has the sequence GLLSVLGSVAKHVLPHVVPVIAEHL-NH2), in that it lacks four residues of the central hinge region of a caerin 1. Litoria eucnemis has three major host defence peptides, two of these are maculatins (e.g. maculatin 1.3; GLLGLLGSVVSHVVPAIVGHF-NH2) which are related in sequence to that of maculatin 1. The other antibiotic peptide is caerin 1.11 (GLLGAMFKVASKVLPHVVPAITEHF-NH2) a peptide related to the caerin 1 peptides of the green tree frogs of Australia. L. eucnemis is the only species of the Litoria genus (that we have studied) which contains both maculatin and caerin peptides in its skin secretion. The three antibiotic peptides of Litoria eucnemis are significantly less active than maculatin 1.1 and other caerins 1 isolated from anurans of the genus Litoria so far studied.

Annotation:
We describe two new species in the microhylid frog genus Copiula from Western Province, Southern Highlands Province, and Gulf Province in southern Papua New Guinea based on morphological and acoustic data. Both species are medium-sized (between 27 – 30 mm SVL), terrestrial frogs with a predominantly beige-colored dorsum and a yellow ventrum. They can be distinguished from each other and from all congeners by their distinct advertisement calls. In the first species calls are short bursts of 3 – 7 rapidly repeated yapping notes lasting 30 – 44 msec at a repetition rate of 11.6 – 16.5 notes/sec, and in the second species calls consist almost exclusively of two notes (occasionally one or three notes) lasting 50 – 91 msec and produced at a repetition rate of 7.1 – 11.3 notes/sec. Calls of the second species are usually uttered in long call series that may start with one or more, one-note calls before increasing to two notes, and occasionally to three notes/call late in the series. Descriptions of these two species brings the number of Copiula known from the New Guinea region to at least 12.

Annotation:
Uperoleia is a large genus of small-bodied terrestrial frogs that occur in Australia and southern New Guinea. With nine species, the Kimberley region in northern Western Australia is the most diverse. Recent surveys of the northwest coast of the Kimberley have revealed a tenth species of Uperoleia. The new species is characterized by a combination of small body size, dark and slightly tubercular dorsal skin, basal webbing between the toes, outer metatarsal tubercle spatulate and oriented perpendicular to the foot, possession of maxillary teeth, a broadly exposed frontoparietal fontanelle and the advertisement call is a high-pitched rasp. All specimens collected have been associated with sandstone boulders or escarpments with flowing water or rock pools. The northwest Kimberley is an isolated region of high rainfall and rugged terrain that possesses high biodiversity for many plant and animal groups and is therefore worthy of special conservation attention.

Annotation:
Studies across large oceanic archipelagos often provide an opportunity for testing different processes driving patterns of species richness. Frogs are among the most abundant vertebrates in the Solomon Islands but little is known of the factors influencing their richness patterns. This study used modelling to determine important ecological and biogeographic factors affecting the species richness of frogs at multiple locations on major islands across the archipelago. Between March 2009 and August 2012, 16 frog species were recorded along 109 transects placed in coastal, lowland, ridge and montane forests across 13 islands. Mean species richness was higher in the North Solomon Islands arc (6.2 species) and decreased eastwards towards the New Georgia islands (4.7 species), and Malaita (3.2 species). A plausible explanation is that the North Solomon Islands arc is closest to New Guinea, a major centre of dispersal in the south-west Pacific. Coastal (4.6 species) and freshwater (4.8 species) forests had lower predicted species richness than lowland, ridge, and montane forest types (all with 6.2 species). In addition, more frogs were predicted in areas with thin leaf litter (6.2 species), dense shrub cover (7.7 species), and moist soils (7.7 species), which are characteristic of undisturbed forests. These results suggest that frog conservation activities in the Solomon Islands should target islands in the west with intact lowland, ridge, and montane forests. Specific knowledge of this nature is vital for amphibian conservation on tropical islands experiencing extensive habitat loss, habitat modification and widespread predicted climate change impacts.

Annotation:
Recent advancement of environmental DNA (eDNA) methods for surveying species in aquatic ecosystems has been used for various organisms and contributed to monitoring and conservation of species and environments. Amphibians are one of the promising taxa which could be monitored efficiently by applying quantitative PCR (qPCR) or next generation sequencing to eDNA. However, the cost of eDNA detection using these approaches can be quite high and requires instruments that are not usually installed in ecology laboratories. For aiding researchers in starting eDNA studies of amphibians, especially those not specialized in molecular biology, we developed a cost efficient protocol using PCR-RFLP method. We attempted to detect eDNA of three Japanese Rana species (Rana japonica, Rana ornativentris, and Rana tagoi tagoi) in various spatial scales including an area close to the Fukushima nuclear power plant where the environment is recovering after the disaster in 2011. Our PCR-RFLP protocol was successful in detecting Rana species in static water in both laboratory and field; however, it could not detect Rana species in non-static water samples from the field. Even a more sensitive detection method (standard qPCR) was unable to detect frogs in all non-static water samples. We speculate that our new protocol is effective for frogs living in lentic habitats, but not for lotic habitats which may still require the gold standard of field observation for detection approach.

Three species of Pleuranthodium were encountered and collected during a survey of gingers at Mount Wilhelm, Chimbu Province, Papua New Guinea. Based on new material, the only previously known Pleuranthodium from this area, P. piundaundense, is described in more detail highlighting new diagnostic characters and its known distribution range is expanded based on identification of older specimens at Edinburgh from two other provinces. Two species so far only known from Mount Wilhelm could not be identified after studying all protologues, types and material from several herbaria. These are here described as new species, P. corniculatum and P. sagittatum. A key with both floral and vegetative characters is provided to all three species. Pleuranthodium corniculatum is distinct in having apical appendages on the calyx, and P. sagittatum has a wrinkled calyx. All species are described and illustrated, and conservation assessments are made.
