DNA Barcode of Parodontidae Species from the La Plata River Basin - Applying New Data to Clarify Taxonomic Problems
Neotropical Ichthyology, 11(3):497-506, 2013 Copyright © 2013 Sociedade Brasileira de Ictiologia DNA barcode of Parodontidae species from the La Plata river basin - applying new data to clarify taxonomic problems Elisangela Bellafronte1, Tatiane Casagrande Mariguela2, Luiz Henrique Garcia Pereira2, Claudio Oliveira2 and Orlando Moreira-Filho1 In the past years, DNA barcoding has emerged as a quick, accurate and efficient tool to identify species. Considering the difficulty in identifying some Parodontidae species from the La Plata basin and the absence of molecular data for the group, we aimed to test the effectiveness of DNA barcoding and discuss the importance of using different approaches to solve taxonomic problems. Eight species were analyzed with partial sequences of Cytochrome c oxidase I. The mean intraspecific K2P genetic distance was 0.04% compared to 4.2% for mean interspecific K2P genetic distance. The analyses of distance showed two pairs of species with K2P genetic divergence lower than 2%, but enough to separate these species. Apareiodon sp. and A. ibitiensis, considered as the same species by some authors, showed 4.2% genetic divergence, reinforcing their are different species. Samples of A. affinis from the Uruguay and Paraguay rivers presented 0.3% genetic divergence, indicating a close relationship between them. However, these samples diverged 6.1% from the samples of the upper Paraná River, indicating that the latter represents a potentially new species. The results showed the effectiveness of the DNA barcoding method in identifying the analyzed species, which, together with the morphological and cytogenetic available data, help species identification. Nos últimos anos o DNA barcoding surgiu como uma ferramenta rápida, precisa e eficiente para identificar espécies. -
A New Genus of Miniature Cynolebiasine from the Atlantic
64 (1): 23 – 33 © Senckenberg Gesellschaft für Naturforschung, 2014. 16.5.2014 A new genus of miniature cynolebiasine from the Atlantic Forest and alternative biogeographical explanations for seasonal killifish distribution patterns in South America (Cyprinodontiformes: Rivulidae) Wilson J. E. M. Costa Laboratório de Sistemática e Evolução de Peixes Teleósteos, Instituto de Biologia, Universidade Federal do Rio de Janeiro, Caixa Postal 68049, CEP 21944 – 970, Rio de Janeiro, Brasil; wcosta(at)acd.ufrj.br Accepted 21.ii.2014. Published online at www.senckenberg.de/vertebrate-zoology on 30.iv.2014. Abstract The analysis of 78 morphological characters for 16 species representing all the lineages of the tribe Cynopoecilini and three out-groups, indicates that the incertae sedis miniature species ‘Leptolebias’ leitaoi Cruz & Peixoto is the sister group of a clade comprising the genera Leptolebias, Campellolebias, and Cynopoecilus, consequently recognised as the only member of a new genus. Mucurilebias gen. nov. is diagnosed by seven autapomorphies: eye occupying great part of head side, low number of caudal-fin rays (21), distal portion of epural much broader than distal portion of parhypural, an oblique red bar through opercle in both sexes, isthmus bright red in males, a white stripe on the distal margin of the dorsal fin in males, and a red stripe on the distal margin of the anal fin in males.Mucurilebias leitaoi is an endangered seasonal species endemic to the Mucuri river basin. The biogeographical analysis of genera of the subfamily Cynolebiasinae using a dispersal-vicariance, event-based parsimony approach indicates that distribution of South American killifishes may be broadly shaped by dispersal events. -

E-mail: [email protected] Abstract Apareiodon agmatos, new species, is described from the upper Mazaruni River and its tributaries, Essequibo Basin, in western Guyana. The new species is distinguishable from all other species of Parodontidae by having an incomplete lat- eral line. The scales of A. agmatos are more numerous than in any previously described parodontid. It has five incisor- like pedunculate teeth on the premaxilla aligned in a straight row, each with a large central spatulate cusp bordered on each side by a minute lateral cusp. The maxilla has two or infrequently three incisors. It shares an unusual pigmentation pattern of one dorsomedial and four lateral black stripes with A. gransabana, which was described from the neighboring upper Río Caroní drainage, Orinoco Basin. Apareiodon agmatos also shares with A. gransabana and Parodon guyanen- sis a higher number (5 versus 4) of teeth than other members of the genus in the premaxillary. Apareiodon agmatos and A. -

Corresponding author. E-mail: [email protected] Abstract Simpsonichtys lopesi n. sp. is described from a temporary pool located in the São Francisco river basin. This species is distinguished from remaining species, except S. adornatus, by the large number of dorsal fin rays, which makes possible a large dorsal fin base length that begins well anterior to the middle of the body, before the vertical line through the pelvic fin. This species differs from S. adornatus by the color pattern of the anal fin, which may have yellow stripes or light dots (vs. small light points), and also by the lower number of dorsal fin rays. Key words: Annual fishes, Neotropical region, temporary pools Resumo Simpsonichthys lopesi n. sp. é descrita de uma poça temporária localizada na bacia do rio São Francisco. A espécie distingue-se das demais, exceto S. adornatus, pelo grande número de raios da nadadeira dorsal, o que confere grande comprimento da base dessa nadadeira que se inicia muito antes da metade do corpo, antes da nadadeira pélvica. -

Cytogenetic Studies in Some Apareiodon Species (Pisces, Parodontidae)
C 2000 The Japan Mendel Society Cytologia 65: 397-402,2000 Cytogenetic Studies in Some Apareiodon Species (Pisces, Parodontidae) Celia Maria de Jesus* and Orlando Moreira-Filho Departamento de Genetica e Evolucbo, Universidade Federal de Sdo Carlos Rodovia Washington Luis, km 235, Caixa Postal 676, CEP 13565-905, Sdo Carlos, SP, Brasil Accepted September 8, 2000 Summary Cytogenetic studies in 6 species of Apareiodon (Pisces, Parodontidae) from different Brazilian hydrographic basins showed a diploid number equal to 2n=54 chromosomes and the ab- sence of morphologically differentiated sex chromosomes. Although the diploid and the fundamental numbers had been constant, some differences were observed concerning the karyotypic structure of the species. A. ibitiensis, Apareiodon sp. A and Apareiodon sp. B presented 50M/SM+4ST chromo- somes, while A. piracicabae, A. vittatus and Apareiodon sp. C presented 52M/SM+2ST ones. Apareiodon piracicabae showed a polymorphism in relation to the number and position of the nucle- olar organizer regions (NORs), while A. vittatus showed a variation in the NORs size. The available data indicate that the Parodontidae family have been submitted to a chromosomal diversification dur- ing their species differentiation process, despite the maintenance of the same diploid number. Key words Apareiodon, Karyotypic evolution, NOR, C-band. The Characiformes fish are widely distributed in the neotropical region, showing a wide varia- tion in the diploid number. Two general trends in the chromosomal evolution can be observed in this order. In fact, some groups show a heterogeneous evolutionary with a diversity in the chromo- some number and the karyotypic structure. In contrast, a more homogenous pattern can be observed in other groups, leading to a relatively stable karyotypes. -
Amazon Alive: a Decade of Discoveries 1999-2009
Amazon Alive! A decade of discovery 1999-2009 The Amazon is the planet’s largest rainforest and river basin. It supports countless thousands of species, as well as 30 million people. © Brent Stirton / Getty Images / WWF-UK © Brent Stirton / Getty Images The Amazon is the largest rainforest on Earth. It’s famed for its unrivalled biological diversity, with wildlife that includes jaguars, river dolphins, manatees, giant otters, capybaras, harpy eagles, anacondas and piranhas. The many unique habitats in this globally significant region conceal a wealth of hidden species, which scientists continue to discover at an incredible rate. Between 1999 and 2009, at least 1,200 new species of plants and vertebrates have been discovered in the Amazon biome (see page 6 for a map showing the extent of the region that this spans). The new species include 637 plants, 257 fish, 216 amphibians, 55 reptiles, 16 birds and 39 mammals. In addition, thousands of new invertebrate species have been uncovered. Owing to the sheer number of the latter, these are not covered in detail by this report. This report has tried to be comprehensive in its listing of new plants and vertebrates described from the Amazon biome in the last decade. But for the largest groups of life on Earth, such as invertebrates, such lists do not exist – so the number of new species presented here is no doubt an underestimate.

In this study we analyze the diet of a population of Dendropsophus branneri from a cocoa plantation in southern Bahia, Brazil. Frogs were captured monthly from August 2010 to July 2011. Stomach contents were retrieved through stomach-flushing and later identified to order level. Our results show that D. branneri feeds mainly on arthropds, such as Diptera, larval Lepidoptera and Araneae. Based on the identified food items and the low number of prey per stomach we conclude that the studied population of D. branneri uses a “sit and wait” strategy. We further conclude that stomach flushing can be successfully applied to frogs from a size of 14.4mm. Key words: trophic resources, stomach flushing, feeding habits, Hylidae, cabruca, Atlantic Rainforest.
