We describe a new species of Cornufer, subgenus Batrachylodes, from high-elevation forests of New Britain Island in the Bismarck Archipelago of Eastern Melanesia. The new species, Cornufer exedrus sp. nov., is a biogeographically disjunct member of the Batrachylodes clade, representing the first record of the subgenus from outside of the Solomon Archipelago. The new species is a small terrestrial form from dense, closed-canopy forests above 1500 meters elevation in the Nakanai Mountains of eastern New Britain. It differs from its closest relatives, the other members of the subgenus Batrachylodes, on the basis of its minute body size, degree of digital disc expansion, reduced subdigital tuberculation, color pattern, and other traits related to its small size. We also provide a description of the new species’ simple advertisement call. The diversity of ceratobatrachid frogs of the Bismarck Archipelago is most likely still underestimated despite several recent surveys. Our understanding of evolutionary trends and species boundaries in the subgenus Batrachylodes currently is hampered by lack of genetic samples and call recordings corresponding to voucher specimens of the endemic species of Bougainville Island.

We describe a new species from the cophyline microhylid genus Rhombophryne, a group of fossorial and terrestrial frogs endemic to Madagascar. Found during herpetofaunal surveys of moist montane forest in the remote north of Ranomafana National Park,Rhombophryne nilevina sp. n. exemplifies two difficulties that hinder taxonomic progress in Malagasy cophyline frogs: micro-endemicity and highly secretive habits. Known from only two adult male specimens, this new species is nonetheless easily distinguishable from all other known Rhombophryne using morphological data, and osteological data collected here via X-ray Micro-Computed Tomography, or " micro-CT ". This species is now the largest known Rhombophryne, and the only one known from Ranomafana National Park, which will make it the southern-most member of the genus pending a forthcoming taxonomic revision involving Plethodontohyla and Rhombophryne. Pairwise distances of the mitochondrial 16s rRNA marker show a minimum genetic distance of 4.9% from other nominal Rhombophryne. We also describe recordings of an advertisement call, emitted from a burrow by the holotype. Rhombophryne nilevina sp. n. is not known to be found syntopically with other Rhombophryne, nor to be present elsewhere in Ranomafana National Park, but it probably does co-occur with a few ecologically similar Plethodontohyla species. Although the type locality is within a protected area, we suggest an IUCN listing of Data Deficient for R. nilevina sp. n., as its area of occupancy is largely undetermined within the park.
Suggested common English name: Buried Diamond Frog
Suggested common Malagasy name: Sahona diamondra nilevina
Suggested common French name: La grenouille de diamant enterré
Diagnosis: A frog assigned to the cophyline genus Rhombophryne on the basis of its divided vomer, the possession of clavicles and knob-shaped terminal phalanges (see Scherz et al. 2016a). This species is characterized by the following suite of characters: large size (SVL at least up to 57.2 mm), wide, short head (HW 180.7% of HL), tympanum 58.6% of eye, forelimb 51.1% of SVL, tibia 42.2% of SVL, hindlimb 152.5% of SVL, large inner metacarpal and metatarsal tubercles, supratympanic fold distinct and raised, running from the posterior corner of the eye straight over the tympanum, then sharply down behind it, extending to join the front of the arm, distinct vomerine teeth forming curved rows posteromedial to the oblong choanae, separated medially by a small cleft, second finger shorter than fourth finger, fifth toe distinctly shorter than third, without finger or toe reduction, finger and toe tips not enlarged. Additionally, R. nilevina is separated from all nominal species of Rhombophryne by an uncorrected pairwise distance of at least 4.9% in the fragment of the 16S rRNA gene, and by at least 3.8% from all known candidate species in this genus.

Etymology: The specific epithet “nilevina” is a Malagasy word meaning “buried.” This name was chosen to recognize the fossorial habits of this species. It is to be treated as an invariable noun in apposition.
Natural history. Both known specimens of R. nilevina were obtained from a relatively flat, poorly drained section of moist montane forest adjacent to a stream, with the holotype found along the bank of this stream. Nearby habitats include a swamp with many large Pandanus and steep forested slopes with relatively smaller trees. However, the calls of R.nilevina seemed to emanate mostly from the flatter, forested area. Males were heard calling during the day, particularly during overcast conditions and after rainfall. Advertisement calls were not heard at night, however, the night-time chorus of other frogs, including Boophis, Spinomantis, Gephyromantis, and Anodonthyla, may have interfered with detection. When heard from a distance, the call is reminiscent of that of an owl. When heard from close proximity, the call sounds like a groan, and is far less melodic. Both specimens were both located by auditory tracking, and found calling from underground: one from a cavity under the roots of a large tree, and the other from a burrow in soft, moist soil alongside the stream. In order to collect the holotype from its burrow, excavation was required. Based on these observations and suggestive morphology, we presume that R. nilevina spend much of their lives underground, possibly coming to the surface for short periods during rainfall, similar to other fossorial Rhombophryne species (Glaw and Vences 2007, D’Cruze et al. 2010). We also note that R. nilevina was discovered in the middle of the wet season, and after a week-long period of particularly heavy, sustained rain.
Distribution: Rhombophryne nilevina has thus far been detected at a single site, near the former village of Andemaka, in the north-west of Ranomafana National Park (Fig. 2). This locality is relatively high-elevation for Ranomafana National Park (ca. 1240 m). To our knowledge, R. nilevina has not been detected by any previous survey, including several conducted by CRH and SML at similarly high-elevation sites in the northern (Miaranony), central (Vohiparara), and southern (Maharira) regions of Ranomafana. Nevertheless, we do not rule out here the possibility that R. nilevina occurs elsewhere in the park. This is in large part due to the secretive habits and potentially ephemeral activity periods of this species (see Natural history). In addition, much of the high-elevation forest of Ranomafana is difficult to access and thus remains sparsely or completely unsurveyed for herpetofauna. Although it is possible that R. nilevina has been overlooked in other eastern rainforest patches, current information suggests that this species is endemic to Ranomafana National Park, and potentially to a much smaller area within the park.

Breviceps carruthersi sp. nov. and Breviceps passmorei sp. nov. are described from northern KwaZulu-Natal. Both new species are distinguished from B. adspersus, B. mossambicus, B. poweri and B. cf. sopranus by substantial interspecific genetic divergence (> 6.8 uncorrected p-distance) in the mitochondrial 16S rRNA gene, differences in advertisement call structure and limited morphological variation. Breviceps carruthersi sp. nov. has a short, pulsatile call with minimal amplitude modulation and groups its calls. Breviceps passmorei sp. nov. differs significantly from B. adspersus and B. mossambicus in call duration and pulse number, but not in pulse rate or dominant frequency. For both new species morphological characters are of limited diagnostic value, necessitating a re-evaluation of the taxonomic status of populations currently assigned to B. adspersus and B. mossambicus in KwaZulu-Natal.
Breviceps carruthersi sp. nov. from Hluhluwe, KwaZulu-Natal; holotype male (SAIAB 204591).
Breviceps carruthersi sp. nov. Minter, Netherlands & Du Preez
Etymology. This species is named for Vincent Carruthers who, through his numerous books and articles on the natural history of southern Africa in general, and frogs in particular, has done much to stimulate interest in these much-maligned creatures.
Distribution and habitat. Currently known only from the area around Hluhluwe and Phinda Game Reserve. ....
Field observations. Calls were recorded between 18h45 and 01h15, during and after moderate to heavy rain. Two males were calling from shallow depressions at the base of grasstufts, while the remainder called from exposed positions on the surface. When the vocal sac is inflated, the white stripe separating the gular patch from the dark eyestripe is conspicuous and may function as a visual signal.

We describe a new species of the endemic frog genus Nasikabatrachus, from the eastern slopes of the Western Ghats, in India. The new species is morphologically, acoustically and genetically distinct from N. sahyadrensis. Computed tomography scans of both species revealed diagnostic osteological differences, particularly in the vertebral column. Male advertisement call analysis also showed the two species to be distinct. A phenological difference in breeding season exists between the new species (which breeds during the northeast monsoon season; October to December), and its sister species (which breeds during the southwest monsoon; May to August). The new species shows 6 % genetic divergence (K2P) at mitochondrial 16S rRNA (1330 bp) partial gene from its congener, indicating clear differentiation within Nasikabatrachus. Speciation within this fossorial lineage is hypothesized to have been caused by phenological shift in breeding during different monsoon seasons—the northeast monsoon in the new species versus southwest monsoon in N. sahyadrensis. It is postulated that proximate triggers of breeding behavior and highly stenotopic adaptation of Nasikabatrachus tadpoles to inhabit cascades during monsoonal stream flows, have led to allopatry on the eastern and western slopes of the Western Ghats, thereby promoting speciation in this ancient genus.

Etymology: The species epithet commemorates Dr. S. Bhupathy, a noted scientist and a field herpetologist, who passed away due to an ill-fated accident while conducting herpetological surveys in Agasthyamalai, Western Ghats on April 28, 2014.

Advertisement calls can be used to aid solving taxonomic problems and understanding the evolution of certain groups. In this study, the advertisement call of Eleutherodactylusbilineatus is described. It is composed by two different notes with a total duration of 0.529–4.241 seconds and dominant frequency of 1.72–3.45 kHz. Additionally, new data is provided on the geographical distribution of Eleutherodactylusbilineatus and the most inland record for this species.

Limited knowledge about species diversity restricts inferences about biogeography and macroecology in Amazonia, where biodiversity documentation has become particularly pressing due to anthropogenic impacts. An emblematic example of poorly known Amazonian amphibian diversity is that of Allobates nurse frogs, in which species boundaries and ranges are unclear. Based on genetic, morphological and call data from samples collected in 14 poorly known sites in Brazil, we identify and describe a new, broadly distributed western Amazonian nurse frog. In the light of the genetic data, combined with examination of more than 400 museum specimens, we also assess the distribution and levels of phenotypic variation in poorly known species from Amazonian lowlands, namely A. flaviventris, A. gasconi, A. subfolionidificans, and A. trilineatus. Lastly, our morphological examinations point to inconsistencies and heterospecific samples in the type series of A. fuscellus, A. gasconi, and A. vanzolinius, as revealed by large variation in key traits. By improving knowledge about species ranges and identifications, we hope that this study will support biodiversity inventories and stimulate further investigations of understudied western Amazonian nurse frogs.

Diagnosis: The new species is included in the genus Allobates on the basis of the phylogenetic results (Fig. 3) and overall similarity with congeners (Fig. 4–5). Allobates tinae sp. nov. is diagnosed by the following combination of characteristics: (i) snout rounded in lateral and dorsal views; (ii) a medium-sized species, mean SVL of males 15.2 mm (range 14.2–15.9 mm), mean SVL of females 15.8 mm (range 14.8–17.2 mm); (iii) dorsal surface of snout uniformly light brown, same color extending posteriorly until eye level; dorsum tan brown in life; (iv) skin texture of dorsum granular, flat small granules scattered from the level of the eyes to the urostyle region; (v) dark brown lateral stripe with well delimited upper and lower edges; (vi) pale dorsolateral stripe present in preserved specimens, conspicuous in life; (vii) oblique lateral stripe absent, pale cream spots scattered on inguinal region of the dark brown lateral stripe, reaching up to two thirds of it towards the forelimbs; (viii) iridescent white ventrolateral stripe conspicuous in live and preserved specimens, unbroken from tip of snout to inguinal region; (ix) bright paracloacal mark present, half-moon shaped; (x) sexual dimorphism in throat and chest coloration of live specimens (golden yellow in males, white in females); (xi) abdominal surfaces cream, reaching towards the flanks (xii) dorsal surface of legs uniform, without transversal dark stripes; (xiii) iris metallic gold, without a pupil ring; (xiv) vocal sac distinct, single, subgular; (xv) maxillary teeth present; (xvi) Finger III not swollen in males; (xvii) basal webbing present between Toes III and IV; (xviii) fringes absent on toes; (xix) diurnal habits, males calling in daytime; (xx) advertisement calls characterized by the emission of tonal notes ranging between 4,875–6,029 Hz.
Etymology The specific epithet honors Dr. Albertina Pimentel Lima, a professor at the Instituto Nacional de Pesquisas da Amazônia (INPA), for her extensive contributions to Al‑ lobates taxonomy. Dr. Lima has described or re-described with colleagues more than a dozen species of nurse frogs. Her work has inspired the first author to investigate Allobates taxonomy.
Distribution The new species is known from lowland western Amazonia in Brazil to the south of the Amazon River (Fig. 2) in the states of Acre, Amazonas and Rondônia. In its type locality (..., Amazonas), Allobates tinae sp. nov. is syntopic with A. gasconi and A. femoralis. To the south (e.g., ..., Acre), it co-occurs with A. hodli, A. subfolionidificans, and A. trilineatus. To the east (e.g., in the middle course of the Madeira River), A. tinae sp. nov. is sympatric with A. caeruleodactylus, A. flaviventris, A. grillisimilis, A. masniger, and A. nidicola (see Simões 2016).

Resumo:Um conhecimento limitado sobre a diversidade de espécies restringe inferências sobre biogeografia e macroecologia na Amazônia, onde documentar padrões de biodiversidade tornou-se particularmente urgente devido a impactos antropogênicos. Um exemplo emblemático de anfíbios amazônicos cuja diversidade é mal conhecida é o das rãs-cuidadoras do gênero Allobates, para as quais as distribuições e os limites entre espécies ainda não estão claros. Com base em dados genéticos, morfológicos e de vocalização de espécimes amostrados em 14 localidades pouco exploradas no Brasil, identificamos e descrevemos uma nova espécie de Allobates de ampla distribuição na Amazônia ocidental. À luz dos dados genéticos, em combinação com o exame de mais de 400 espécimes de museus, também examinamos a distribuição e a variação fenotípica em espécies pouco conhecidas das planícies amazônicas, nomeadamente A. flaviventris, A. gasconi, A. subfolionidificans e A. trilineatus. Por último, a análise de espécimes depositados em coleções zoológicas aponta para inconsistências e amostras heteroespecíficas na série tipo de A. fuscellus, A. gasconi e A. vanzolinius, como revelado por uma grande variação em caracteres-chave. Ao melhorar o conhecimento sobre as distribuições e identificações de espécies, esperamos que este estudo apoie inventários de biodiversidade e estimule novas investigações sobre as pouco conhecidas rãs-cuidadoras da Amazônia ocidental.

Nyctimantis rugiceps Boulenger, 1882 (Fig. 1A) is a Neotropical treefrog (Duellman & Trueb 1976; Faivovich et al. 2005) known only from disjunct localities in Amazonian Colombia, Ecuador, and Peru (Pérez-Villota et al. 2009). This species has the skin of the skull co-ossified and reproduces—including calling behavior, egg deposition and tadpole development—in water-filled tree or bamboo cavities (Duellman & Trueb 1976; Duellman 1978). Given its secretive behavior, this is a poorly known species and, as noted by Duellman (1978: 169), “the major clue to the life history of Nyctimantis is the calling behavior of the males”. Unfortunately, the only quantitative description of the advertisement call of N. rugiceps is a brief passage in Duellman (1978) based on four specimens from Santa Cecilia, Ecuador, where important variables are missing (e.g., call duration). More importantly, graphs illustrating the waveform and spectrogram are missing. Considering these limitations and the importance of advertisement calls to the study of anurans (Köhler et al. 2017), we provide a quantitative description using a call recording obtained in Leticia, Amazonas, Colombia.

We describe a new species of nurse-frog (Aromobatidae, Allobates) from Floresta Nacional de Carajás, southeastern Brazilian Amazonia. Allobates carajas sp. nov. is distinguished from similar congeneric species by the combination of the following characters: body-size range (snout-to-vent length 16.5–19.1 mm), dorsal color pattern with a dark brown hourglass-shaped mark, by the absence of a pale dorsolateral stripe and presence of a pale ventrolateral stripe, absence of a pale paracloacal mark, by overall bright yellow ventral colors of live male and female specimens, and by the posterior labium of tadpoles, with a single row of pyramidal papillae medially. The advertisement call of the new species is highly variable, with four possible temporal arrangements of notes (continuous emission of notes separated by regular silent intervals, continuous emission of notes separated by irregular silent intervals, emission of discrete note trills, and sporadic emission of single notes). Duration of notes range between 0.020–0.060 s, and the dominant frequency of notes range from 4.75 to 5.38 kHz. The new species is currently known only from forested habitats within Floresta Nacional de Carajás.
