... The presence of discreetly pointed discs on finger (as in D. tapacurensis sp. nov.) was only reported for D. shiwiarum and D. ozzyi [53,54], which belongs to the D. microcephalus and D. ruschii Groups, respectively [2]. All species of the D. decipiens group have had its advertisement call described [4,16,[46][47][48][49]. ...
We describe a new species of the Dendropsophus decipiens Group, morphologically most resembling D. haddadi but genetically more closely related to D. oliveirai and likely endemic from the Atlantic Forest biome, northeastern Brazil. The new species can be distinguished from all species of the D. decipiens Group based on the combination of morphological features, advertisement call and phylogenetic position based on mitochondrial DNA gene sequences. The new species emits simple calls in series of 3–9 notes, each with 9–29 pulses, and dominant frequency varying from 5578–6422 Hz, and exhibit a minimum of 8% genetic distance (16S mitochondrial gene) in comparison to its congeners. The new taxa represent the sixth species of the D. decipiens Group, which likely harbors more undescribed taxa, corroborating the view that Neotropical species richness is fairly underestimated.
... During herpetological surveys of the amphibian and reptile fauna in the vicinity of the upper Madeira River (southwestern Amazonia, Rondônia, Brazil) in 2011-2013, we recorded several anuran advertisement calls that were markedly different from calls of all described species of Dendropsophus known from Brazilian Amazonia. The frogs emitting these calls morphologically resemble members of the D. microcephalus species group (sensu Faivovich et al. 2005), and preliminary bioacoustic analyses revealed that their calls are monophasic, i.e., they consist of only one call type (e.g., Orrico et al. 2014), and have a remarkably high dominant frequency (above 8 kHz). ...
... In the Dendropsophus microcephalus species group, a similarly high dominant frequency has been reported only for two "monophasic" species: D. meridianus (Lutz, 1954) and D. ozzyi Orrico, Peloso, Sturaro, Silva, Neckel-Oliveira, Gordo, Faivovich &Haddad, 2014 (Pombal andBastos 1998;Orrico et al. 2014). A high dominant frequency (~ 9 kHz) was also reported for D. minusculus (Rivero, 1971) from Belem, Brazil, by Duellman and Pyles (1983), but a low dominant frequency (~ 3 kHz) was recorded by Tarano (2011) from a population of the same species closer to the type locality in Venezuela. ...

Recent studies have shown that species diversity of the South American frog genus Dendropsophus is significantly underestimated, especially in Amazonia. Herein, through integrative taxonomy a new species of Dendropsophus from the east bank of the upper Madeira River, Brazil is described. Based on molecular phylogenetic and morphological analyses, the new species is referred to the D. microcephalus species group, where it is differentiated from its congeners mainly by having a green bilobate vocal sac and an advertisement call comprising 1–4 monophasic notes emitted with a dominant frequency of 8,979–9,606 Hz. Based on intensive sampling conducted in the study area over the last ten years, the new species is restricted to the east bank of the upper Madeira River, although its geographic range is expected to include Bolivian forests close to the type locality.
... Recent expeditions to Amazonia have revealed that our knowledge about the species diversity of anurans is still incomplete. New species continue to be found even in well-known and well-studied places, and several species have been shown to consist of several cryptic lineages (e.g., Ferreira et al. 2017;Fouquet et al. 2016;Orrico et al. 2014;Peloso et al. 2014Peloso et al. , 2016Simões et al. 2013;. For example, several species of Boana Gray, 1825 were recently named or revalidated for Amazonian populations, whereas authors also highlighted that many additional taxa still await formal description or revalidation (Caminer & Ron 2014;Fouquet et al. 2016;Peloso et al. 2018). ...
Expeditions to unexplored or little explored places are important for discovering new species and also for collecting new samples (including specimens and tissues for DNA sequencing ) that may help resolve a plethora of taxonomic problems. In the 19th century, several naturalists explored a number of localities in Amazonia, describing species for which type material was deposited, mostly, in European museums of natural history. Some of these types were lost or destroyed in World War II and recent expeditions have focused on sampling new material from the type localities. material from Boana cinerascens, which allowed us to infer phylogenetic relationships of the Boana punctata group (i.e., green Boana), based on DNA sequence data, and to revaluate the status of B. cinerascens and its synonyms. We designate, redescribe and illustrate a neotype for B. cinerascens, which was described by Spix in 1824, from the Municipality of Tefé, State of Amazonas, Brazil. We revalidate, redescribe, and illustrate Hyla granosa gracilis Melin, 1941(= Boana gracilis). Corroborating previous studies, the green Boana were not recovered as a monophyletic group. Boana cinerascens is sister of B. gracilis plus a clade containing B. atlantica + B. punctata (both species not recovered as monophyletic).

... The Dendropsophus microcephalus species group comprises more than 30 species, of which 13 are included in the two tentatively recognized clades: the D. decipiens and D. rubicundulus clades [3,11,13]. Two known morphological synapomorphies for this group are the absence of labial tooth rows and marginal papillae on the oral disc of larvae (with a reversal in the D. decipiens clade; [3,14]). The D. microcephalus group is the latest diverging taxon of Dendropsophus, and the relationship with other groups, as well as between its species remains controversial (e.g. ...
The Dendropsophus decipiens clade comprises four species: D. berthalutzae, D. decipiens, D. haddadi, and D. oliveirai. Tadpoles of these species were described, but data on their internal morphology are lacking. We provide the first description of the buccopharyngeal anatomy, chondrocranial morphology, and cranial, hyoid and hyobranchial musculature of the tadpole of D. decipiens. Larvae of D. decipiens are characterized by the absence of lingual papillae, presence of fan-like papilla on the buccal floor, presence of a single-element suprarostral cartilage, presence of a small triangular process at the basis of the processus muscularis, m. levator mandibulae lateralis inserted on the nasal sac, and m. subarcualis rectus II-IV with a single, continuous slip. Tadpoles are likely macrophagous, although not as specialized as those of other species of the genus, suggesting some degree of diversification on the feeding habits within Dendropsophus.
... formalmente conhecidos para o país (Costa & Bérnils, 2015;Segalla et al., 2016).

RESUMO Apesar da elevada riqueza de anfíbios e répteis conhecida para a porção Sul-Ocidental da Amazônia brasileira, o conhecimento sobre estes é pontual e poucos estudos avaliaram as variações temporais na ocorrência e abundância das espécies. Os objetivos deste estudo foram descrever as taxocenoses de anfíbios e répteis em uma localidade da Reserva Extrativista Chico Mendes, verificar quais variáveis climáticas influenciam as flutuações temporais na riqueza e abundância e identificar as principais espécies de anfíbios e répteis influenciadas por elas. A área de estudo está localizada na região do Seringal Etelvi, porção sudoeste da Reserva, município de Brasiléia, estado do Acre. A coleta de dados ocorreu entre outubro de 2011 e setembro de 2012, num total de 48 dias de amostragem, com os métodos de procura limitada por tempo e armadilhas de interceptação e queda. Foram registrados 978 espécimes de 31 espécies de anfíbios e 54 de répteis. Maior riqueza e abundância de anfíbios ocorreram durante o período chuvoso, sendo a abundância associada positivamente com a temperatura média. Apenas a abundância de répteis foi maior durante o período chuvoso. Porém, tanto riqueza quanto abundância mensais foram associadas positivamente com a temperatura média. Quatro anfíbios, Allobates gr. marchesianus, Hamptophryne boliviana (Parker, 1927), Hypsiboas geographicus (Spix, 1824) e Rhinella marina (Linnaeus, 1758), e dois répteis, Kentropyx pelviceps Cope, 1868 e Norops fuscoauratus (D’Orbigny, 1837), tiveram suas abundâncias mensais associadas positivamente com a temperatura média. O lagarto Dactyloa punctata (Daudin, 1802) teve a abundância mensal associada com a precipitação. Foi possível verificar o aumento da riqueza e abundância de anfíbios e répteis durante períodos em que a disponibilidade de recursos é favorável para muitas espécies. As espécies podem reagir de formas diferentes às variações climáticas, enquanto algumas são sensíveis às flutuações, outras parecem não responder facilmente ou não reduzir suas abundâncias em períodos potencialmente desfavoráveis.
... There is also an indication that distress calls of the Neotropical Haddadus binotatus reaches ultrasound frequencies (Toledo & Haddad 2009). While pure ultrasonic frog calls might be exceptional and geographically restricted to noisy torrent environments, the existence of some ultrasound components in anuran vocalizations is probably more frequent than currently recognized ( Orrico et al. 2014). Our own recordings of a variety of anurans indicate that especially in miniaturized frogs, important components of the emitted frequencies are above 20 kHz, and also in other frogs, harmonics can reach the ultrasonic range (Fig. 21). ...
Vocalizations of anuran amphibians have received much attention in studies of behavioral ecology and physiology, but also provide informative characters for identifying and delimiting species. We here review the terminology and variation of frog calls from a perspective of integrative taxonomy, and provide hands-on protocols for recording, analyzing, comparing, interpreting and describing these sounds. Our focus is on advertisement calls, which serve as premating isolation mechanisms and, therefore, convey important taxonomic information. We provide recommendations for terminology of frog vocalizations, with call, note and pulse being the fundamental subunits to be used in descriptions and comparisons. However, due to the complexity and diversity of these signals, an unequivocal application of the terms call and note can be challenging. We therefore provide two coherent concepts that either follow a note-centered approach (defining uninterrupted units of sound as notes, and their entirety as call) or a call-centered approach (defining uninterrupted units as call whenever they are separated by long silent intervals) in terminology. Based on surveys of literature, we show that numerous call traits can be highly variable within and between individuals of one species. Despite idiosyncrasies of species and higher taxa, the duration of calls or notes, pulse rate within notes, and number of pulses per note appear to be more static within individuals and somewhat less affected by temperature. Therefore, these variables might often be preferable as taxonomic characters over call rate or note rate, which are heavily influenced by various factors. Dominant frequency is also comparatively static and only weakly affected by temperature, but depends strongly on body size. As with other taxonomic characters, strong call divergence is typically indicative of species-level differences, whereas call similarities of two populations are no evidence for them being conspecific. Taxonomic conclusions can especially be drawn when the general advertisement call structure of two candidate species is radically different and qualitative call differences are thus observed. On the other hand, quantitative differences in call traits might substantially vary within and among conspecific populations, and require careful evaluation and analysis. We provide guidelines for the taxonomic interpretation of advertisement call differences in sympatric and allopatric situations, and emphasize the need for an integrative use of multiple datasets (bioacoustics, morphology, genetics), particularly for allopatric scenarios. We show that small-sized frogs often emit calls with frequency components in the ultrasound spectrum, although it is unlikely that these high frequencies are of biological relevance for the majority of them, and we illustrate that detection of upper harmonics depends also on recording distance because higher frequencies are attenuated more strongly. Bioacoustics remains a prime approach in integrative taxonomy of anurans if uncertainty due to possible intraspecific variation and technical artifacts is adequately considered and acknowledged.

... Notice that "Type I" is synonym of "primary" and "Type II" of "secondary" for Dendropsophus advertisement calls [29]. Monophasic calls have a single type of note while biphasic calls, two (see [12]). We measured number of notes, call duration (s), number of pulses per call per note, duration (s) of Type I and Type II notes, number of pulses per Type I and per Type II note, Type I and Type II note pulse rate, Call pulse repetition rate, Call repetition rate per minute, and dominant frequency (Hz). ...
We describe a new species of the Dendropsophus leucophyllatus Group from the Atlantic Forest of the southern region of State of Bahia, Brazil. It can be distinguished from all species of the D. leucophyllatus Group on the basis of morphological characters (especially its unique dorsal pattern and snout in dorsal view), advertisement calls and divergence in mitochondrial DNA gene sequences. The inclusion of D. anceps on the group remains controversial but our phylogenetic analyses do not recover the new species as sister to syntopic species of the D. leucophyllatus Group (with or without D. anceps). These results also highlight the palimpsest that is past relation between the Atlantic and Amazon forests.

... The association between the cytogenetic dataset and 16S rDNA sequences may be very helpful in future analyses, especially because the species-level taxonomy of Dendropsophus has been subject to several changes. A number of Dendropsophus species has been described in the last few years (Rivera-Correia and Orrico 2013, Ortega-Andrade and Ron 2013, Orrico et al. 2014, Fouquet et al. 2015, Peloso et al. 2016) as well as species synonymizaton has been proposed (Guarnizo et al. 2012). Therefore, a reliable association between different sets of data is fundamental for further integrative studies. ...
The diploid number 2n = 30 is a presumed synapomorphy of Dendropsophus Fitzinger, 1843, although a
noticeable variation in the number of biarmed/telocentric chromosomes is observed in this genus. Such
a variation suggests that several chromosomal rearrangements took place after the evolutionary origin of
the hypothetical ancestral 30-chromosome karyotype; however, the inferred rearrangements remain unknown.
Distinct numbers of telocentric chromosomes are found in the two most cytogenetically studied
species groups of Dendropsophus. In contrast, all three species of the Dendropsophus marmoratus (Laurenti,
1768) group that are already karyotyped presented five pairs of telocentric chromosomes. In this study,
we analyzed cytogenetically three additional species of this group to investigate if the number of telocentric
chromosomes in this group is not as variable as in other Dendropsophus groups. We described the
karyotypes of Dendropsophus seniculus (Cope, 1868), D. soaresi (Caramaschi & Jim, 1983) and D. novaisi
(Bokermann, 1968) based on Giemsa staining, C-banding, silver impregnation and in situ hybridization
with telomeric probes. Dendropsophus seniculus, D. soaresi and D. novaisi presented five pairs of telocentric
chromosomes, as did the remaining species of the group previously karyotyped. Though the species of
this group show a high degree of karyotypic similarity, D. soaresi was unique in presenting large blocks of het-ITSs (heterochromatic internal telomeric sequences) in the majority of the centromeres. Although
the ITSs have been interpreted as evidence of ancestral chromosomal fusions and inversions, the het-ITSs
detected in the karyotype of D. soaresi could not be explained as direct remnants of ancestral chromosomal
rearrangements because no evidence of chromosomal changes emerged from the comparison of the karyotypes
of all of the species of the D. marmoratus group.
