ABSTRACT

Using an integrative approach (morphology of the adult and larvae, bioacoustics, osteology, karyotype, and molecular data), we described a new tetraploid species of Odontophrynus to the Mantiqueira mountain range, in southeastern Brazil. The data suggest that Odontophrynus toledoi sp. nov., O. juquinha and Odontophrynus sp. (aff. juquinha) comprise a clade with specimens distributed along three distinct mountain ranges in Brazil: Mantiqueira (O. toledoi sp. nov.) and Espinhaço (O. juquinha) mountains, both in southeastern Brazil, and Diamantina Plateau (O. aff. juquinha), in northeastern Brazil. The new species is morphologically similar and closely related to O. juquinha, but is distinguished in morphology (both adult and larval), karyotype (O. toledoi sp. nov. is tetraploid and O. juquinha is diploid), and corroborated by phylogenetic inferences. We also show that these species do not exchange haplotypes in the 16s gene. Furthermore, although the raw acoustic parameters of Odontophrynus toledoi sp. nov. and O. juquinha overlap at the limits of their ranges, we found a clear difference in the acoustic space structure.

Diagnosis: Odontophrynus toledoi sp. nov. is a medium-sized species belonging to the genus Odontophrynus based on the phylogenetic position and a combination of morphological characters: granular skin on the dorsum and venter, head wider than long, snout truncate in profile, tympanum hidden, first subarticular tubercle on toe I enlarged, inner metatarsal tubercle large, tarsal fold short (Savage & Cei 1965; Caramaschi & Napoli 2012). The new species belongs to the Odontophrynus americanus species group based on phylogenetic affinities and the combination of the following characters: absence of large dorsal, tibia and forearm glandular warts, with postorbital, temporal, and parotoid glandular warts not distinctly developed but with a series of small glandular warts of irregular size and shape, forming glandular ridges longitudinally oriented, on postorbital-parotoid regions (Caramaschi & Napoli 2012). Odontophrynus toledoi is distinguished from the remaining species belonging to the O. americanus group by the following combination of characters: (1) medium sized (SVL = 40.4–51.8 mm in males and 45.0–54.5 mm in females of O. toledoi; Table 1); (2) head wider than long (HW/HL = 1.31); (3) dorsal surface of head, arms, body and limbs dark brown with arms and limbs with light brown stripes; (4) light mid-dorsal stripe present or interrupted in most of the specimens; (5) yellowish stripe between the eyes, resembling a ‘)’ shape; (6) increased number of longitudinally oriented dorsal glandular ridges; (7) karyotype with 2n = 4X = 44, with fundamental number = 88; (8) advertisement call with dominant frequency of 775–1033 Hz; (9) pulse rate of 89–132 pulses/s; (10) large tadpoles (mean TL = 42.91–56.18 mm); (11) one–two submarginal papillae on the posterior labium of each side of the oral disc near the posterior emargination; and (12) spiracle sinistral, short, inner wall fused to the body with small distal portion free.

Etymology: The specific epithet honors Professor Luís Felipe Toledo for his contribution in solving the mysteries of the natural history of Neotropical amphibians, especially those from southeastern Brazil and mostly within the Atlantic Forest, where the new species resides.

Abstract

The genus Proceratophrys currently comprises 40 species, of which five are distributed within the Caatinga domain and associated phytophysiognomies along northeastern Brazil. During field surveys at high altitudinal sites in Boqueirão da Onça region, northern Bahia state, we collected individuals of Proceratophrys that could not be assigned to any species currently known to occur within the Caatinga, which we describe herein. The new species can be diagnosed from remaining congeners based on vocalization, adult and tadpole morphology, and is also supported by molecular data (mitochondrial 16S, cytochrome b, and nuclear rhodopsin). We recovered the new species nested in the clade composed of species distributed within the Caatinga domain and associated phytophysiognomies, exhibiting a minimum of 7% of genetic divergence for the 16S gene in comparison to all its congeners. The new species seems to be restricted to high altitude locations (above 800 m) at the Boqueirão da Onça region, which represents the largest remaining contiguous Caatinga remnant (∼986,000 ha) being classified as of extreme biological importance.

[Herpetology • 2021] Proceratophrys korekore • A New Species of Proceratophrys Miranda-Ribeiro, 1920 (Anura, Odontophrynidae) from Southern Amazonia, Brazil

Proceratophrys korekore

DOI: 10.7717/peerj.12012

Abstract

Based on concordant differences in morphology, male advertisement call, and 16S mtDNA barcode distance, we describe a new species of Proceratophrys from southern Amazonia, in the states of Mato Grosso and Pará, Brazil. The new species is most similar to P. concavitympanum and P. ararype but differs from these species by its proportionally larger eyes and features of the advertisement call. Additionally, genetic distance between the new species and its congeners is 3.0–10.4% based on a fragment of the 16S rRNA gene, which is greater than the threshold typically characterizing distinct species of anurans. Using an integrative approach (molecular, bioacoustics, and adult morphology), we were able to distinguish the new species from other congeneric species. The new species is known only from the type locality where it is threatened by illegal logging and gold mining as well as hydroelectric dams.

Proceratophrys korekore sp. nov.

Diagnosis. The new species can be distinguished by the following combination of traits: (1) medium size (39.8–44.1 mm SVL in adult males; 43.8–57.6 mm SVL in adult females); (2) upper eyelid border with fused and small pointed warts; (3) proportional measurements ED/END 1.1–1.3; (4) presence of a single row of tubercles of different sizes bordered with some sparse tubercles on the forearm; (5) call duration of 0.162–0.332 s; 18–31 pulses/call; pulse rate of 96.4–111.1 pulses/s.

Etymology. The specific epithet “korekore” is a noun in apposition that means frog in the language of the Mundurukus, an indigenous group that inhabits the southwestern parts of Pará state and the northern region of Mato Grosso state, Brazil. We suggest the following Portuguese vernacular names “sapo-korekore” or “sapo-de-chifre-dos- mundurukus”.

Natural History. Proceratophrys korekore sp. nov. was found inhabiting only dense ombrophilous forest formations on both banks of the Teles Pires River. During nocturnal surveys between 18:00 and 21:00 h in the rainy season (from October to June), we observed males of P. korekore sp. nov. calling from the leaflitter on the banks of temporary streams. Some males were also found calling on bare soil near the edges of waterbodies. Additionally, individuals of the new species were observed during surveys (both diurnal and nocturnal) moving through the forest or captured using pitfall traps, even far from water bodies. Sympatric species include Ameerega munduruku, Ceratophrys cornuta, and Lithodytes lineatus. The main anthropogenic threats to the type locality are illegal logging and the often-subsequent deforestation for cattle grazing. Furthermore, illegal gold mining inside the forests (locally called “garimpo”) was observed during fieldwork. The activity of these illegal miners consists of clearing all vegetation of a target area and then destroying entire sections of stream bank to extract gold using mercury, a heavy metal that pollutes water supplies and poisons fish stocks (Silva et al., 2018). Finally, the Teles Pires River has also been dammed by multiple hydroelectric power plants, which have caused considerable natural habitat losses and fragmentation.

Abstract

A new species of frog of the genus Odontophrynus is described from grassland of the subtropical regions of Argentina, Brazil, and Paraguay based on morphological, osteological, bioacoustical, cytogenetic, and molecular evidence. The new species is characterized by having medium size; rostral and eye-nostril glandular warts well developed; several long glandular ridges, longitudinally oriented, on dorsum; several medium-sized, nearly rounded, dark-brown dorsal blotches; light mid-dorsal stripe continuous and well defined or restricted to the head and the urostyle regions; and mid-dorsal stripe, interorbital, and dorsolateral bands with a moderately whitish highlight, light brown, or reddish coloration. Additionally, the new species has a skull with nasals slightly separated both from each other and frontoparietals, and frontoparietal fontanelle not exposed. The advertisement call consists of a single multipulsed note with a dominant frequency of 820–1,121 Hz and a pulse rate of 99.3–140.7 pulses/s. The chromosomal complement is diploid with 2N = 2X = 22 chromosomes and nucleolar organizer regions on the interstitial regions of the short arm of chromosome pair 4. The phylogenetic analysis allowed us to recover the new species belonging to the O. americanus species group with genetic distances from its congeners ranging from 2.11 to 4.82% in a partial sequence of 16S ribosomal RNA gene. The new species is geographically isolated from the other currently known diploid species of the group, but in some localities is found in sympatry or syntopy with the tetraploid O. americanus.

Etymology.—The specific epithet honors Osvaldo Alfredo Reig (Buenos Aires, Argentina, 1929–1992) for his noteworthy contributions to the biological sciences of South America (Reig and Fontdevila, 1989; Boido and Tenner, 1991; Fontanals, 2012). He published more than 200 studies on morphology, anatomy, cytogenetics, paleontology, and systematics of amphibians, reptiles, and mammals. Regarding amphibians, Reig proposed the suborder Neobatrachia, and described two of the oldest known species of frogs, Notobatrachus degiustoi and Vieraella herbsti, from the Jurassic of Patagonia, Argentina. He worked at Universidad de Buenos Aires and Instituto Miguel Lillo (Argentina), Universidad Simón Bolívar (Venezuela), and Universidad Austral (Chile), among other academic centers, where he was strongly committed to scientific development, education of young researchers, and consolidation of working groups. Sadly, he had to go into exile from Argentina and Chile due to coups d’etat. In 1973, Reig received his Ph.D. in Zoology and ´ Paleontology from the University of London. In 1989, the Universidad Autonoma de Barcelona named him as Doctor ´ Honoris Causa.

[Herpetology • 2020] Revising the Taxonomy of Proceratophrys Miranda‐Ribeiro, 1920 (Anura: Odontophrynidae) from the Brazilian Semiarid Caatinga: Morphology, Calls and Molecules support A Single Widespread Species

Abstract

Recently, Proceratophrys cristiceps was redescribed along with the description of two species from the Caatinga biome: P. aridus and P. caramaschii. However, only a small fraction of the populations related to such species in Northeastern Brazil was examined, and most populations of central Caatinga were not contemplated in this analysis. Comparisons were also based exclusively on external morphology, precluding a more accurate delimitation of such taxa in the light of multiple characters. Such geographic paucity and reliance in only one data source caused the species status of most central Caatinga populations to be uncertain. Thus, the revision of Proceratophrys populations from the Caatinga biome is of utmost importance to establish a solid taxonomic background and to test the validity of the described species. Based on morphologic, morphometric, acoustic, and multilocus genetic data, we define the range of inter‐ and intrapopulation variation in the parameters we analyzed, establishing which ones are useful as diagnostic characters for Proceratophrys in the Caatinga. We found no evidence supporting P. aridus and P. caramaschii as distinct species and thus place them as junior synonyms of P. cristiceps. Our results reinforce the importance of using multiple lines of evidence to avoid taxonomic instability.

Abstract

Natural rain forest enclaves in northeastern Brazil (called Brejos de Altitude) are present in isolated areas surrounded by the semiarid Caatinga biome. Among these montane areas, the Araripe Plateau in Ceará state harbors Caatinga, Cerrado, and Atlantic Forest remnants and is considered a priority area for biodiversity conservation. Herein, we describe a new species of Proceratophrys (Amphibia: Anura: Odontophrynidae; Horned Frogs) endemic to the Araripe Plateau. Based on nuclear and mitochondrial DNA sequences, we show that this new species is related to the Amazonian species P. concavitympanum but can be diagnosed based on the row of tubercles on the forearm and by the number, size, and disposition of tubercles on the dorsal region. It is also widely disjunct, known only from the mesic forests of the Araripe Plateau, 2400 km away from the type locality of P. concavitympanum. The new species depends on streams for reproduction and is currently known from an area that is severely impacted by deforestation and diversion of local streams for agriculture and recreation. Considering the many threatened species occurring in the same region, there is a need for future studies to quantify the new species' full distribution and evaluate population trends to correctly assess its conservation status.

Etymology.—The Araripe Plateau spans the borders of Ceará, Pernambuco and Piauí states. ‘‘Araripe,’’ from the ancient tupi, ararype, means ‘‘on the Araras River’’ (arara, arara + ’y, river + pe, on the; Arara means Macaw in Tupi and in vernacular Portuguese). Because the new species is known only from the Araripe region, we name it after this area. The specific epithet ararype is treated as a noun in apposition

DOI: 10.11646/zootaxa.4329.4.2

Abstract

The Odontophrynus americanus species group is a complex of diploid and tetraploid species hardly distinguished by morphological characters. It currently consists of three allopatric diploid species (i.e. O. cordobae, O. lavillai, and O. maisuma) and one widely distributed tetraploid species (i.e. O. americanus). We herein describe a new diploid allopatric species from campo rupestre, a typical phytophysiognomy of the Espinhaço Range, Brazil. The new species is distinguishable by the diploid complement of 2n = 2x = 22 chromosomes, small to medium-sized dorsal dark brown blotches with low contrast on a light brown background, light mid-dorsal stripe absent or greatly interrupted in most specimens with yellowish coloration as the background of both head and flanks of the body, advertisement call with dominant frequency of 840–1080 Hz, pulse rate of 90.5–106.7 pulses/s, and small tadpoles (TL = 24.30–35.69 mm).

Etymology. The specific epithet is a noun in apposition and honors “Juquinha das Flores ”, a hermit whose simplicity and gentleness made him a folkloric figure at Serra do Cipó, type locality of the new species. According to the legend, Juquinha nursed from a wolf, ate scorpions, was bitten by over a hundred snakes and his age exceeded a hundred years. He used to collect flowers and roots and trade them for general items or food. His love for the mountains and the joy he provided to those who met him made him a very popular and loved figure.

Juquinha lived and died twice. The first time, he was found dead by his brother and woke up during his own funeral, strengthening the belief that he was immortal. In fact, he suffered from catalepsy, a rare disease that causes the heart to stop, as if the person had died. The second and actual death happened in 1983, at unknown age. In 1987, a homage statue to Juquinha was erected at the Serra do Cipó and became a tourist spot.

Abstract

Proceratophrys caramaschii was described only from a single locality in Mucuripe, Fortaleza municipality, Ceará state, Brazil. The discovery of a new population of this poorly known species facilitated the collection of new data regarding colour in life, vocalization, habitat, and geographic distribution. It has a much wider distribution than formerly thought, is considerably variable in its colour pattern, and its reproductive strategy is strongly associated with the beginning of the rainy season. Males call from the ground and hidden in vegetation. The advertisement call is a short trill of notes. Further data is necessary to evaluate the threat status of this species.
