First Record of Adenomera Saci Carvalho & Giaretta, 2013 Herpetology Notes, volume 8: 183-185 (2015) (published online on 10 April 2015) First record of Adenomera saci Carvalho & Giaretta, 2013 (Anura: Leptodactylidae) for the State of Maranhão, Northeastern Brazil Kássio de Castro Araújo1, Micheli Véras dos Santos1, Tássia Graziele Pires Lima1, Etielle Barroso de Andrade1,2,3,*and Luiz Norberto Weber2 The Neotropical genus Adenomera Steindachner, and is an important conservation area for the state, 1867, belonging to subfamily Leptodactylinae (Pyron located between the sources of the rivers Itapecuru and and Wiens, 2011), is widely distributed in South Alpercatas. The local climate is sub-humid to humid, America east of the Andes and is currently represented with annual rainfall 1200-1400 mm. The maximum by 18 species distributed in seven clade: A. andreae, temperature ranges from 31º C to 33º C and minimum A. heyeri, A. hylaedactyla, A. lutzi, A. marmorata, A. of 19º C to 21º C (IBGE, 1998). The specimens were martinezi and A. thomei (Fouquet et al., 2014; Frost, found calling on soaked soil among bulrush tufts in a 2014). Adenomera saci, belonging to A. martinezi flooded field covered by emergent vegetation within a clade (Fouquet et al., 2014), was recently described typical Cerrado area. Despite having nocturnal habits from the taxonomic revision of populations previously recognized as A. martinezi (Carvalho and Giaretta, 2013). Adenomera saci occurs in rocky Cerrado environments associated with palm grove marshes in the regions of Central Western (States of Mato Grosso, Mato Grosso do Sul and Goiás), and Northern Brazil (only in the State of Tocantins; Carvalho and Giaretta, 2013). Herein, we present the first occurrence of A. saci for the state of Maranhão, Northeastern Brazil. During fieldwork at the Parque Estadual do Mirador (-45.473611º and -6.791111º, Datum SAD 69), located between the municipalities of Mirador, Grajaú, and São Raimundo das Mangabeiras, southern State of Maranhão, we recorded several individuals of A. saci calling at dusk, around 17:30 h on April 12, 2014. The Parque Estadual do Mirador has about 767,000.00 ha 1 Núcleo de Pesquisa em Biodiversidade e Biotecnologia - BIOTEC, Campus de Parnaíba, Universidade Federal do Piauí - UFPI, 64202020, Parnaíba – PI, Brasil. 2 Programa de Pós-Graduação em Biodiversidade e Biotecnologia - BIONORTE, Universidade Federal do Maranhão - UFMA, 65080040, São Luís - MA, Brasil.

We recorded This new record for the state of Maranhão extends the calls of a single male with a digital recorder (Marantz geographic range of A. saci in about 360 km in a straight PMD660) coupled to a directional microphone line to northeast of Colinas do Tocantins (Carvalho and (Sennheiser Me66/K6) set at a sampling rate of 44.1 Giaretta, 2013), in the state of Tocantins (Fig. 2), being kHz and a 16-bit resolution.

  • On the Uncertain Taxonomic Identity of Adenomera Hylaedactyla (Cope, 1868) and the Composite Type Series of A
    Copeia 107, No. 4, 2019, 708–723 On the Uncertain Taxonomic Identity of Adenomera hylaedactyla (Cope, 1868) and the Composite Type Series of A. andreae (Muller,¨ 1923) (Anura, Leptodactylidae) Thiago R. de Carvalho1, Ariovaldo A. Giaretta2, Natan M. Maciel3, Diego A. Barrera4,Cesar´ Aguilar-Puntriano4,5,Celio´ F. B. Haddad1, Marcelo N. C. Kokubum6, Marcelo Menin7, and Ariadne Angulo4,5 Adenomera andreae and A. hylaedactyla are two widespread Amazonian frogs that have been traditionally distinguished from each other by the use of different habitats, toe tip development, and more recently through advertisement calls. Yet, taxonomic identification of these species has always been challenging. Herein we undertake a review of type specimens and include new phenotypic (morphology and vocalization) and mitochondrial DNA information for an updated diagnosis of both species. Our morphological analysis indicates that the single type (holotype) of A. hylaedactyla could either belong to lineages associated with Amazonian forest-dwelling species (A. andreae clade) or to the open-formation morphotype (A. hylaedactyla clade). Given the holotype’s poor preservation, leading to the ambiguous assignment of character states for toe tip development, as well as a vague type locality encompassing a vast area in eastern Ecuador and northern Peru, the identity of this specimen is uncertain. Morphology of toe tip fragments and the original species description suggest that A. hylaedactyla could correspond to at least two described species (A. andreae or A. simonstuarti) or additional unnamed genetic lineages of the A. andreae clade, all bearing toe tips expanded into discs. Analysis of morphometric data, however, clustered the holotype with the Amazonian open-formation morphotype (toe tips unexpanded).

  • Restriction Fragment Analysis of the Ribosomal DNA of Paratelmatobius and Scythrophrys Species (Anura, Leptodactylidae)
    Genetics and Molecular Biology, 26, 2, 139-143 (2003) Copyright by the Brazilian Society of Genetics. Printed in Brazil www.sbg.org.br Research Article Restriction fragment analysis of the ribosomal DNA of Paratelmatobius and Scythrophrys species (Anura, Leptodactylidae) Luciana B. Lourenço1, Paulo C.A. Garcia2 and Shirlei M. Recco-Pimentel1 1Departamento de Biologia Celular, Instituto de Biologia, Universidade Estadual de Campinas (UNICAMP), Campinas, SP, Brazil. 2Instituto de Biociências, Universidade Estadual Paulista (UNESP), Rio Claro, SP, Brazil. Abstract Physical maps of the ribosomal RNA gene 28S of species belonging to the genera Paratelmatobius and Scythrophrys were constructed, using five restriction endonucleases. The restriction sites for Bam HI, Bgl II, Bst EII, and Eco RI had similar positions in all species, although there were interspecific differences in the size of the restriction fragments obtained. An additional Pvu II site was found in Scythrophrys specimens from Piraquara (State of Paraná, Brazil) and from São Bento do Sul (State of Santa Catarina, Brazil), but not in the Scythrophrys specimens from Rancho Queimado (State of Santa Catarina, Brazil). This finding is in agreement with the hypothesis regarding the existence of two species in the genus Scythrophrys. On the other hand, the extra Bst EII site considered in the literature to be a synapomorphy for the subfamilies Leptodactylinae and Telmatobiinae was not observed in the genera Paratelmatobius and Scythrophrys, which brings new questions about some taxonomic classifications that include Paratelmatobius in Leptodactylinae and Scythrophrys in Telmatobiinae. Interspecific variation was observed in the size of the restriction fragments analyzed and, in the case of group I Scythrophrys, there was also a variation between the individuals of the two populations.

Whereas the external larval morphology of some species of Adenomera has been described, their internal mor- phology remains poorly studied. In this work, we provide information on the reproductive features and larval morphol- ogy of populations of Adenomera from northeastern Argentina and southwestern Brazil, including the first description of the chondrocranium and hyobranchial apparatus for a member of the genus Adenomera. We found that, morphologi- cally, the buccal cavity of A. diptyx is more similar to that of the species of the Leptodactylus fuscus group than to that of A. marmorata, the only species of Adenomera whose buccal cavity is known. Adenomera diptyx shares with the species of the L. fuscus group a semicircular crest in the prenarial region, two pairs of infralabial papillae, four lingual papillae, and few papillae on the roof and the floor of the cavity.
