We examined differences in morphology and advertisement calls of a large sample of frogs from the Australo-Papuan Region that resemble Litoria bicolor, and compared them with examples of that species from Australia. Consistent differences in body size, body proportions, and advertisement call structure among populations demonstrate that at least seven distinct species occur in the Australo-Papuan region, and that only the population represented by the holotype from the Northern Territory of Australia is Litoria bicolor s.s. Herein we describe four new species from the Papuan Region and comment on the origin and evolution of the Papuan members of the Litoria bicolor complex in the region.

A New Species

We describe a new species of the Bokermannohyla circumdata group from the Estação de Pesquisa e Desenvolvimento Ambi-ental Galheiro (EPDA-Galheiro) (19o 12′S; 47o 08′W), Municipality of Perdizes, State of Minas Gerais, a mid-altitudinal (~ 850m above sea level) riparian forest environment in the Cerrado of southeastern Brazil. Bokermannohyla napolii sp. nov. is alliedto the large-sized species of the group, diagnosed on the basis of adult morphology/morphometrics, and mainly vocalizations.Adult specimens of the new species are most closely related to those of B. luctuosa and B. circumdata, but can be differentiatedfrom the former by having distal subarticular tubercle of finger III bifid/divided in males, and finger IV bifid/divided in malesand females; and from both B. luctuosa and B. circumdata by a distinctive advertisement call structure. We also provide bioa-coustic data on seven other species of the genus, including previously unknown advertisement calls of B. circumdata and B. carvalhoi, and re-description of the advertisement calls of B. luctuosa, B. ibitiguara, B. nanuzae, B. sazimai, and B. hylax.

We describe ten new species of treefrogs assigned to the genus Boophis (Anura: Mantellidae) and resurrect two species from synonymy, based on materials collected during fieldwork in Madagascar, carried out mainly between 2000 and 2007. Our comparative database assembled over the past years comprises fresh material for molecular analysis from all 58 nominal Boophis species, and advertisement call recordings from all except three species. We follow an integrative approach and combine molecular, bioacoustic and morphological evidence to diagnose the new species. In most cases, the new species have uncorrected molecular divergences of over 4–5% in the mitochondrial 16S rRNA gene to their closest relatives. In some cases the divergences are lower (2–2.5%) but are then accompanied by distinct differences in advertisement calls or morphology. Boophis piperatus sp. nov. from Ranomafana National Park is a small brown species assigned to the B. majori group that is similar to B. miniatus but differs in morphology and advertisement calls. Boophis arcanus sp. nov. is assigned to the B. majori group as well and is known from only two female specimens from a site close to Ranomafana; it is described mainly based on its strong genetic differentiation (> 7.2% to all other species). Boophis entingae sp. nov. is a species of the Boophis goudoti group occurring in northern Madagascar, similar to and sympatric with B. brachychir, but with a strongly different advertisement call. Boophis roseipalmatus sp. nov. belongs to the B. goudoti group, is similar to B. madagascariensis, and appears to replace this species in most of northern Madagascar, with possible areas of sympatry in the north east. Boophis spinophis sp. nov. is an enigmatic, morphologically highly divergent species from Ranomafana National Park that belongs into the B. goudoti group but differs from all other spe-4 · Zootaxa 2383 © 2010 Magnolia Presscies in the group by having distinct dermal tubercles along the lateral parts of the shank and around the elbow. Boophis praedictus sp. nov. is a sibling species of B. albilabris in the B. albilabris group, diagnosable by its red iris periphery and distributed in rainforest along the east coast. Boophis sandrae sp. nov. belongs to the B. luteus group and is superficially similar to the sympatric B. elenae, but has a faster call and smaller body size. Boophis miadana sp. nov. and B. haingana sp. nov., both in the B. albipunctatus group and syntopically occurring at Andohahela National Park, are related to B. ankaratra and B. schuboeae and differ mainly by their advertisement calls. Boophis luciae sp. nov., also in the B. albipunctatus group, differs from the sympatric B. albipunctatus and B. sibilans by having slightly smaller body size and different advertisement calls. We furthermore resurrect Rhacophorus obscurus Boettger, 1913 (as Boophis obscurus in the B. goudoti group) from the synonymy of Boophis goudoti as well as Rhacophorus andrangoloaka Ahl, 1928 (as Boophis andrangoloaka in the B. microtympanum group) from the synonymy of Boophis rhodoscelis, and propose to consider Rhacophorus brevirostris Ahl, 1928 as junior synonym of Boophis andrangoloaka. We discuss our integrative methodological approach and the different lines of evidence used to delimitate the species described or resurrected herein. By applying IUCN Redlist criteria, we evaluate the threat status of the species considered: six species are classified Data Deficient (B. arcanus, B. haingana, B. miadana, B. piperatus, B. praedictus, B. spinophis), four Vulnerable (B. andrangoloaka, B. entingae, B. roseipalmatus, B. sandrae), and two Least Concern (B. luciae, B. obscurus).

Three New Species

Three new species of the genus Oligaphorura are described from southwestern China (O. wanglangensis sp. nov.) and Russian Far East (O. ussurica sp. nov. and O. kedroviensis sp. nov.). The first species is most similar to O. inya (Weiner & Kaprus’, 2014) known from the Altai Mountains, and can be distinguished from the latter by larger body size and the number of ventral psx (00/000/121101m in O. wanglangensis sp. nov. vs 1/000/212101m in O. inya). The other two species, together with O. montana Weiner, 1994, O. pseudomontana Sun & Wu, 2012 and O. chankaensis Sun & Wu, 2012, form a distinct species-group characterized by the presence of 4+4 pso on antennal base and full-sized anal spines. Both these new species differ from the known congeners of this group by having only 2+2 posterior pso on the head. O. ussurica sp. nov. and O. kedroviensis sp. nov. can be separated due to different number of abdominal pso, i.e. 5(6)5554 in the former vs 44454 in the latter species.

Adults and tadpoles of a new species of the genus Leptodactylus are described from southeastern Brazil. Leptodactylus thomei sp.nov. can be found amidst the leaf litter within cocoa plantations along the northern coastal region of the state of Espírito Santo. It can be distinguished from other species of the Leptodactylus marmoratus group by its advertisement call, which is described, together with agonistic calls, and compared to advertisement calls of other species of the group that occur in southern and southeastern Brazil. The systematics of associated populations is discussed.

A New Species

Based on concordant differences in male advertisement call, tadpole morphology, and absence of haplotype sharing in the barcoding 16S mitochondrial DNA, we describe here a new species of spotted leaf frog of the genusPhasmahylafrom Atlantic Forest, State of Rio de Janeiro, Southeast Brazil. The new species is most similar toP. cochranae(type locality) andP. spectabilis(type locality). It differs from these species by the size of the calcar, moderate-sized body (snout-vent length 30.4–34.4 mm in adult eight males), and in the advertisement call. The tadpoles ofPhasmahyla lisbellasp. nov. differ fromP. exilis,P. spectabilis,P. timbo,P. guttataandP. jandaiabecause they do not have row of teeth in the anterior part; differ fromP. cruziby the shape of the anterior end of the oral disc. Through genetic data (phylogenetic distance and haplotype genealogy) we diagnosed the new species where the genetic divergences among its congeners is about 3–6% in a fragment of the 16S rRNA gene, which is above the threshold typically characterizing distinct species of anurans. However, the new species can be distinguished from other congeneric species based on an integrative approach (molecular, bioacoustics, larval, and adult morphology).

A New Species

We describe a new species of forest frog in the genus Platymantis from New Britain Island, Bismark Archipelago, Papua New Guinea. The new species is a morphologically cryptic form that has masqueraded for almost four decades under the name P. schmidti (formerly P. papuensis schmidti, Brown & Tyler, 1968). The new species is microsympatric with the geographically widespread P. schmidti at two known localities. We diagnose the new species on the basis of its distinctive advertisement call and slight but consistent differences in body size and proportions. Calling males of the new species appear to prefer more elevated perches than do males of P. schmidti and the new species may exhibit a greater extent of sexual size dimorphism.

Additional Support

Previously, only one species of torrent frog (Amolops larutensis) was thought to occur throughout Peninsular Malaysia. However, genomic work has demonstrated that populations from eastern Peninsular Malaysia form two separate lineages that are genetically distinct from A. larutensis that is now restricted to the western half of Peninsular Malaysia. This study demonstrates that all three lineages can be morphologically distinguished from each other, thereby providing additional support for the recognition of the eastern lineages as two distinct species. These lineages are described herein as Amolops gerutu sp. nov. from the eastern states of Kelantan, Terengganu, and Pahang, and A. australis sp. nov. from the southern-most state of Johor. In general, these two new species form a clade that is sister to A. larutensis and can be readily distinguished from it by having: (1) considerably denser and more pronounced dorsal tubercles, and (2) the posterodorsal surface of thighs having dense, dark stippling as opposed to broad vermiculations. Although differences in other morphometric characters were detected, their utility as diagnostic characters should be applied with caution due to the large intraspecific variation that overlaps among different species in many of the characters we measured. As such, we advocate for the use of tuberculation and pattern of the posterodorsal portion of the thighs as primary diagnostic characters. These characters can readily distinguish A. larutensis from the two new species. To differentiate A. australis sp. nov. from A. gerutu sp. nov. and A. larutensis, body size can be a good diagnostic character as A. australis sp. nov. is significantly smaller in both males (mean = 31.04 ± 1.59 mm) and females (mean = 46.48 ± 3.2 mm). Additionally, we show a strong positive correlation between body size and elevation, with populations from montane forests (>900 m asl) being considerably larger than populations at lower elevations.

Nurse frogs (Aromobatidae: Allobates) are probably the most extensively studied genus by taxonomists in Brazilian Amazonia. The southwestern portion of Amazonia is the most species-rich: as many as seven species may occur in sympatry at a single locality. In this study, we describe a new species of nurse frog from this region. The description integrates data from larval and adult morphology, advertisement calls and DNA sequences. Allobates velocicantus sp. nov. is distinguished from other Allobates mainly by the absence of hourglass-shaped dark marks on the dorsum and dark transverse bars on the thigh; a throat that is white centrally and yellow marginally; basal webbing on toes II and III; finger I longer than finger II; and an advertisement call composed of 66–138 pulsed notes with a note duration of 5–13 ms, inter-note intervals of 10–18 ms and a dominant frequency of 5,512–6,158 Hz. Tadpoles of the new species have 3–4 short, rounded papillae on the anterior labium, 16–23 papillae on the posterior labium, and a labial keratodont row formula 2(2)/3(1). This is the fifth species of Allobates described from the state of Acre, southwestern Brazilian Amazonia.

The 16S Rrna Gene

Based on concordant differences in morphology, male advertisement call, and 16S mtDNA barcode distance, we describe a new species of Proceratophrys from southern Amazonia, in the states of Mato Grosso and Pará, Brazil. The new species is most similar to P. concavitympanum and P. ararype but differs from these species by its proportionally larger eyes and features of the advertisement call. Additionally, genetic distance between the new species and its congeners is 3.0–10.4% based on a fragment of the 16S rRNA gene, which is greater than the threshold typically characterizing distinct species of anurans. Using an integrative approach (molecular, bioacoustics, and adult morphology), we were able to distinguish the new species from other congeneric species. The new species is known only from the type locality where it is threatened by illegal logging and gold mining as well as hydroelectric dams.

Anuran advertisement calls are life history traits associated with sexual selection and reproduction, and they play an important role in premating isolation mechanisms between species. Comparative bioacoustical analyses of these calls can be useful for taxonomic purposes. Phylogenetic relationships within the genera Pseudis are controversial, especially those related to P. platensis, which is often considered a full species or a subspecies within P. paradoxa. The advertisement call of P. platensis has not been described in detail; therefore, call comparisons of these two conspecifics have not been possible. In this study, we describe the advertisement call and diel activity pattern of P. platensis in the Brazilian Pantanal and compare the calls of P. platensis and P. paradoxa to elucidate whether acoustical parameters may help resolve the present uncertain taxonomic treatment. The advertisement call of P. platensis lasted 0.21 ± 0.01 s and consisted of a short series of 8.05 ± 0.69 distinct pulses (9.34 ± 2.94 ms of pulse duration). The vocal activity of the species was largely restricted to a few hours after dusk (7 – 11 p.m.), which is inconsistent with the diurnal and nocturnal calling behavior described for other Pseudis congeners. The advertisement calls of P. platensis and P. paradoxa were similar in note duration, number of pulses per note and dominant frequency. The geographic variation of calls within species was similar to that found among species. This bioacoustical comparison does not provide new insights into whether P. platensis should be considered a distinct species.
