A New Species of Pseudopaludicola Miranda-Ribeiro, 1926 (Anura: Leptodactylidae: Leiuperinae) from an Amazonia-Cerrado Transitional Zone, State of Tocantins, Brazil
The Neotropical genus Pseudopaludicola includes 24 species distributed throughout South America. Herein, we formally describe the 25th member of this Neotropical clade as a new species: Pseudopaludicola jazmynmcdonaldae sp. nov. from an Amazon-Cerrado transitional zone in Brazil. The recognition of this new species is supported by adult morphology, advertisement call, and molecular data. It is diagnosed mainly by the following characters: small size; upper eyelids smooth, with no palpebral tubercles; heel smooth, with no enlarged conical tubercle; terminal phalanges knobbed, with no T-shaped terminal phalanges or expanded toe tips; relatively short hind limbs (tibiotarsal articulation just reaching the corner of the mouth); single, subgular, smooth, dark vocal sac in life, with no warty texture; and an advertisement call composed of regular series of short multipulsed notes, emitted at high rate. O gênero Pseudopaludicola é composto por 24 espécies distribuídas na América do Sul. Aqui, descrevemos o vigésimo quinto membro deste clado neotropical a partir de espécimes coletados numa zona de transição Amazônia-Cerrado do Brasil Central. O reconhecimento desta nova espécie é suportado por morfologia de adultos, canto de anúncio e dados moleculares. A espécie é diagnosticada principalmente pelo seu pequeno tamanho; pálpebras superiores lisas, sem tubérculos palpebrais; calcanhar liso, sem tubérculo cônico hipertrofiado; ausência de falanges terminais em forma de T ou pontas dos dedos do pé expandidas; membros posteriores relativamente curtos (articulação tibiotarsal atingindo apenas o canto da boca); saco vocal único, subgular, escuro em vida e liso, sem textura verrucosa; e um canto de anúncio composto por uma série regular de notas curtas pulsadas, emitidas a uma taxa elevada.Abstract
Resumo
Pseudopaludicola jazmynmcdonaldae sp. nov. holotype (ZUFMS-AMP 11255, SVL = 14.7 mm), an adult male. (A) Dorsal and (B) ventral views; (C) lateral view of head; ventral views of (D) hand and (E) foot.
Holotype and three paratypes of Pseudopaludicola jazmynmcdonaldae sp. nov. in life. (A) ZUFMS-AMP 11255 (holotype, adult male, call voucher, SVL = 14.7 mm); (B) couple in axillar amplexus (adult male: ZUFMS-AMP 11249, SVL = 13.9 mm; adult female: ZUFMS-AMP 11250, SVL = 14.7 mm); (C) ZUFMS-AMP 11257 (adult male, call voucher, SVL = 14.4 mm); and (D) its single, subgular, smooth, dark vocal sac in life, with no warty texture skin.
(A) Oscillogram of the entire advertisement call with ten series of multi-pulsed notes and (B) audiospectrogram (top) and corresponding oscillogram (bottom) detailing three multi-pulsed notes of the holotype of Pseudopaludicola jazmynmcdonaldae sp. nov. (ZUFMS-AMP 11255). The holotype was recorded on 01 February 2018 at 1811 h; air temperature 29.7°C, relative humidity 91%.
Phylogenetic relationships of the species of the genus Pseudopaludicola based on the 12S and 16S rDNA mitochondrial genes. Bayesian posterior probabilities are given near the nodes.
Audiospectrogram (top) and corresponding oscillogram (bottom) detailing the multipulsed note of a topotypic male of Pseudopaludicola atragula. This male was recorded by Ariovaldo A. Giaretta on 18 February 2015 at 1657 h; air temperature, 27.0°C.
