The genus Dendropsophus Fitzinger contains 108 recognized species (Frost 2020) distributed in nine groups according to Faivovich et al. (2005). However, recent phylogenetic analysis the presence of nonmonophyletic (e.g., Wiens 2010; Fouquet 2011; Motta 2012; Jansen 2019) suggesting that relationships among require careful revision. Species this are tropical and subtropical South America, including Trinidad, southward northern Argentina Uruguay northward Central America southern Mexico...
Boana hobbsi is a poorly known hylid frog currently placed within the punctata group. Yet, morphological, ecological and bioacoustic traits do not support this placement, with no molecular data being available to date test hypothesis. Based on newly collected mitochondrial DNA sequences, morphological review field observations, we provide new insight into phylogenetic relationships, variations geographic distribution of B. hobbsi. Our findings reveal that nested (with strong support)...
A new tree frog species of the genus Scinax from interfluve between Purus and Madeira rivers, Brazilian Amazonia, is described illustrated. The diagnosed by medium body size, snout truncate in dorsal view, ulnar tarsal tubercles absent, nuptial pads poorly developed, skin on dorsum shagreen, light brown with dark spots markings, white groin black spots, anterior posterior surfaces thighs black, iris bright orange. advertisement call consists a single short note, 16−18 pulses dominant...
The Brazilian mountain ranges from the Guiana Shield highlands are largely unexplored, with an understudied herpetofauna. Here amphibian and reptile species diversity of remote Serra da Mocidade range, located in extreme northern Brazil, is reported upon, biogeographical affinities taxonomic highlights discussed. A 22-days expedition to this range was undertaken during which specimens were sampled at four distinct altitudinal levels (600, 960, 1,060 1,365 m above sea level) using six...
The Amazon catchment is the largest river basin on earth, and up to 30% of its waters flow across floodplains. In open waters, floating plants known as meadows abound. They can act vectors dispersal for their associated fauna and, therefore, be important spatial structure communities. Here, we focus amphibian diversity in Amazonian over large scales. We recorded 50 species 57 sites, covering around 7000 km along courses. Using multi‐site generalised dissimilarity modelling zeta diversity,...
The accumulation of studies delimiting species in Amazonia has not only shed light on the patterns its outstanding richness but also allowed a better understanding processes diversification within this immense region. Nevertheless, vast knowledge gaps remain even for prominent anuran complexes, such as Rhinella margaritifera group. This clade toads comprises 23 valid species-level taxa, mainly distributed South America's Dry Diagonal and Atlantic trans-Andean rainforests. Species boundaries...
The number of species anurans in the Amazon is highly underestimated with new studies reporting discovery a large every year. This advance biodiversity due to use molecular tools, especially 16S rRNA gene barcoding, which used identify and discover cryptic lineages. Few central have sequence data available public databases, contrasts considerable richness this biome. aim present study was test for presence using mPTP delimitation algorism. We morphologically identified 26 species, 23 were...
Abstract In this paper we describe some aspects of the reproductive biology Leptodactylus hylaedactylus from open areas Central Amazonia, Brazil. We calling site, season, daily pattern activity, chamber structure, vocalizations and tadpole morphology. Males called amidst grasses bushes in urban areas, throughout year, a greater number males were heard period 16:00 to 20:00 h. The eggs are deposited underground chambers, which spherical or elliptical. Larval development occurs inside...
Abstract: Snakes are a diverse group of terrestrial vertebrates the order Squamata. Despite that, in Amazonian biome, information about distribution and identification snakes is limited when compared to other groups. Additionally, Amazonia there sampling bias towards areas geographically close urban centers more densely populated areas. This turn leads false gaps poorly accessible Amazonia. In this article we report composition snake assemblages six Brazilian Amazonia, based on field...
A species list of amphibians from Santa Isabel do Rio Negro in Brazilian Amazonia is provided. Collections were made March–April 2012 along each two 3-km trails with the following sampling methods: (1) pitfall traps drift fences; (2) visual and auditory surveys; (3) chance encounters. The trail at Daraá north Negro, whereas other Ayuanã south river. Forty anurans one salamander representing 20 genera nine families recorded. composition was compared those 16 studies conducted Guiana, Imeri,...
Anurans in the Rhinella margaritifera group have a long history of taxonomic confusion, mainly by morphological similarity between species and lack acoustic genetic data for many 19 described species. Herein, we presented gildae based on recently collected specimens from its type locality. We provide patterns variation, measurements, advertisement release calls infer phylogenetic position R. gildae. The geographical distribution was updated, occurring two Amazonian localities Maranhão state,...
The present study reports an inventory of lizard species from a region at the central Jatapú River located in state Amazonas, Brazil. fauna was surveyed using three sampling methods: diurnal and nocturnal visual search, pitfall traps with drift fences, incidental collections. We recorded 24 belonging to 18 genera eight families. Non-parametric estimators richness (Bootstrap, Chao 2, Jackknife 1, Ace) were used estimate percentage total sampled. Expected varied 27 estimated via Bootstrap 30...
Leposoma percarinatum is one of the two recognized parthenogenetic species in lizard family Gymnophthalmidae, and only females have been reported to date. Here we report describe first known males attributed from localities northwestern Amazonia. We compare morphological variation (15 meristic 10 discrete characters, all relevant identification Leposoma) these populations with that specimens unisexual test hypothesis they belong same species. did not find significant differences between...
