“…This study also provides new records of occurrences for the state of Maranhão. We present the first record of Leptodactylus natalensis for the interior of the state of Maranhão, 385 km away from Ilhas Canários, Delta do Parnaíba municipality ( Leite et al, 2008 ); this species was previously known only from the coastal region of Brazil ( Frost, 2023 ). We also provide the first record of Leptodactylus pustulatus in Maranhão, in Aldeias Altas municipality, located 289 km away from Sete Cidades National Park, state of Piauí ( Araújo et al, 2020 ); this species is known to occur in arid and semiarid regions of northeastern Brazil ( Frost, 2023 ).…”

Brazil stands out for presenting the highest amphibian anuran diversity in the world. However, taxonomic studies that address characteristic of larval stage of anurans are incipient, representing only 62% of known species. We assess the species diversity of tadpoles from eastern Maranhão state, mid-northern region of Brazil based on morphological and molecular identification (i.e., 16S rRNA gene fragment), and we also provide characteristics of the habitats occupied by each species. We carried out 30 field samplings during 13 months in 16 environments along an ecotonal area, over five cities inside the limits of state of Maranhão, between the Maranhão Babaçu Forest and Cerrado ecoregions. We searched for tadpoles in a variety of water bodies, and the tadpoles that reached the developmental stage between 34 to 40 Gosner were morphologically identified. The tadpoles collected herein represent 26 species belonging to five families. The external morphology enabled the identification of 24 species, while the molecular data recognized 22 unique evolutionary units. The most represented family was Hylidae (Hylinae 11 spp., Phyllomedusinae one spp.) followed by Leptodactylidae (Leptodactylinae seven spp., Leiuperinae three spp.), Microhylidae (Gastrophryninae two spp.), and Bufonidae (two spp.). Our results show that oral morphology was the most important character for identifying tadpoles based on morphology, and the specific 16S rRNA primer was suitable for molecular identification. This study pioneers the use of both morphological and molecular data to identify tadpoles in the state of Maranhão. It also provides, for the first-time, habitat characteristic for the species. Our study reveals a high number of anuran species sampled at the larval stage in the region, identifies species that require further taxonomic and systematic attention, and extends the geographic distribution of six species, three of which represent new occurrences for the state. Our results strengthen the hypothesis that the diversity of amphibians from Maranhão is underestimated and highlight the importance of herpetological inventories in poorly sampled areas, decentralizing the knowledge of biodiversity.

“…Leptodactylus natalensis é endêmica do Brasil, com registros de ocorrência ao longo da faixa litorânea entre os estados do Maranhão e Rio de Janeiro, desde as planícies até 900 metros de altitude (Izecksohn & Carvalho-e-Silva, 2001a,b;Santos & Amorim, 2006;Leite Jr. et al, 2008;Santana et al, 2008;Freitas et al, 2018).…”

Leptodactylus natalensis é endêmica do Brasil, com registros de ocorrência ao longo da faixa litorânea entre os estados do Maranhão e Rio de Janeiro. Trata-se de uma espécie comum, encontrada principalmente em florestas secundárias. Ocorre em unidades de conservação e não há ameaças evidentes que possam colocá-la em risco de extinção. Por essas razões, Leptodactylus natalensis foi avaliada como Menos Preocupante (LC).
