“…All specimens were identified by Dr. Mirco Solé and deposited in the Herpetological Collection of Universidade Estadual de Santa Cruz (Bahia - Brazil). Due to the absence of a taxonomic key, we identified the species seeking their description in taxonomic articles ( Cruz and Peixoto 1983 ; Duellman and Wiens, 1992 ; Pombal et al, 1995 ; Caramaschi and Cardoso, 2006 ; Nunes and Pombal, 2010 ; Nunes et al ., 2012 ; Araujo-Vieira et al, 2020 ). Three species of Scinax were morphologically identified as putative new species, being named as Scinax sp.1, Scinax sp.2, and Scinax sp.3 (these species were differentiated morphologically from all other species described for that region).…”

Molecular species delimitation methods are efficient tools to identify species, including the discovery of new taxa and cryptic organisms, thus being useful to biodiversity studies. In the present work, 16S mitochondrial sequences and cytochrome oxidase I (COI) were used to evaluate the richness of species in the genus Scinax and Ololygon from a biodiversity hotspot in Atlantic Forest. A total of 109 specimens formally belonging to eight species of Scinax and three species of Ololygon were collected in 13 localities along the state of Bahia (northeastern Brazil) and one site in Espírito Santo (southeastern Brazil). Of the Scinax species collected in this study, three were morphologically differentiated from other described species and identified as putative new species (Scinax sp.1, Scinax sp.2 and Scinax sp.3). The species delimitations were inferred using three different methods: ABGD, PTP and mPTP which allowed recognizing 11 Scinax species and five Ololygon species. Scinax sp. 1, Scinax sp. 2 and Scinax sp. 3, have been confirmed as new putative species and Ololygon argyreornata possibly contains cryptic species. We suggest additional studies, including morphological and bioacoustic data to validate these new putative species.

A New Snouted Treefrog of the Genus Scinax (Anura, Hylidae) From the White-Sand Forests of Central Amazonia

et al. 2022

We describe through integrative taxonomy a new species of snouted treefrog of the genus Scinax from white-sand forests of the Rio Negro Sustainable Development Reserve in Central Amazonia, Brazil. The new species is phylogenetically related to other Scinax with striped eyes and pulsed advertisement calls. It differs from other Amazonian species mainly by having snout-vent length 21.6-25.4 mm (n¼11) in adult males and 24.8-27.0 mm (n¼9) in females, snout subacuminate in dorsal view, a dark brown lateral stripe on each flank (fading posteriorly), brown tadpoles with labial keratodont row formula 2(2)/3 and keratodont row P-2 longer than P-1 and P-3, and an advertisement call consisting of a single pulsed note with a call duration of 502-652 ms, 79-105 pulses/note and a dominant frequency of 3,811-4,543 Hz. The new species clusters within a major, well-supported phylogenetic clade grouping several candidate and recently described species as well as species previously included in the former Scinax staufferi species group (viz., S. cruentomma, S. fuscomarginatus, S. staufferi, and S. wandae). The phylogenetic relationships and structural pattern in the advertisement calls of these species highlight the need for a redefinition and reevaluation of the monophyly of the S. staufferi species group.

“…Regarding the composition and distribution patterns, most amphibian species recorded in Serra de Santana and Nascente do Potengi priority areas (N = 11, 57.9%, Table 1) have their distributions predominantly in the Caatinga, with marginal records in Atlantic Forest and/or eastern Cerrado (Narvaes & Rodrigues 2009, Linares & Melo 2011, Palmeira et al 2011, Lantyer-Silva et al 2016, Alves da Silva et al 2020, Dubeux et al 2020, Mângia et al 2020, Vaz-Silva et al 2020, or are common in both the Caatinga and Atlantic Forest (Andrade et al 2020, Lima et al 2020. The remaining amphibian species recorded in the sampled areas (N = 8, 42.1%, Table 1) have wider geographic distributions in South America, being common in ≥ 3 biomes; most of them are widespread in the diagonal of open formations composed of Chaco, Cerrado and Caatinga biomes, also entering adjacent areas of Amazonia and Atlantic Forest (Oliveira et al 2018, Barrio-Amorós et al 2019, Araujo-Vieira et al 2020, Camurugi et al 2020, Magalhães et al 2020, Pereyra et al 2021.…”

The herpetofauna of priority highland areas for conservation of the Caatinga in the state of Rio Grande do Norte, northeastern Brazil

et al. 2023

The Brazilian Caatinga has already lost extensive areas of original vegetation, thus it becomes imperative to perform fauna inventories within this region to fill geographical sampling gaps. Herein, we present a taxonomic list of the herpetofauna of a mountain chain located in the central zone of Rio Grande do Norte (RN) state whose region includes two priority areas for conservation of the Caatinga: “CA087 – Serra de Santana” in the west, and “CA078 – Nascente do Potengi” in the east. The sampling was carried out using methods of visual searching, pitfall traps with drift fences, specimens rescued during vegetation suppression activities in wind energy projects, occasional encounters, and third-party records. We recorded 19 amphibian species and 53 reptile species (23 lizards, 24 snakes, five amphisbaenians and one chelonian). About half of the recorded species have distributions entirely or mostly in the Caatinga. The mountain range sampled in this study harbors virtually all species found in nearby lowlands of the “sertaneja” depression of RN state, plus some relevant species with relictual distributions in the Caatinga, highlighting the importance of these highland areas for conservation of the Caatinga herpetofauna.
