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. -
Historical Biogeography of Cynolebiasine Annual Killifishes
Journal of Biogeography (J. Biogeogr.) (2010) 37, 1995–2004 ORIGINAL Historical biogeography of cynolebiasine ARTICLE annual killifishes inferred from dispersal–vicariance analysis Wilson J. E. M. Costa* Laborato´rio de Sistema´tica e Evoluc¸a˜ode ABSTRACT Peixes Teleo´steos, Departamento de Zoologia, Aim To analyse the biogeographical events responsible for the present Universidade Federal do Rio de Janeiro, Caixa Postal 68049, CEP 21944-970, Rio de Janeiro, distribution of cynolebiasine killifishes (Teleostei: Rivulidae: Cynolebiasini), RJ, Brazil a diversified and widespread Neotropical group of annual fishes threatened with extinction. Location South America, focusing on the main river basins draining the Brazilian Shield and adjacent zones. Methods Phylogenetic analysis of 214 morphological characters of 102 cynolebiasine species using tnt, in conjunction with dispersal–vicariance analysis (diva) based on the distribution of cynolebiasine species among 16 areas of endemism. Results The basal cynolebiasine node is hypothesized to be derived from an old vicariance event occurring just after the separation of South America from Africa, when the terrains at the passive margin of the South American plate were isolated from the remaining interior areas. This would have been followed by geodispersal events caused by river-capturing episodes from the adjacent upland river basins to the coastal region. Optimal ancestral reconstructions suggest that the diversification of the tribe Cynolebiasini in north-eastern South America was first caused by vicariance events in the Parana˜–Urucuia–Sa˜o Francisco area, followed by dispersal from the Sa˜o Francisco to the Northeastern Brazil area. The latter dispersal event occurred simultaneously in two different cynolebiasine clades, possibly as a result of a temporary connection of the Sa˜o Francisco area before the uplift of the Borborema Plateau during the Miocene. -
Species Limits and DNA Barcodes in Nematolebias, a Genus of Seasonal
225 Ichthyol. Explor. Freshwaters, Vol. 24, No. 3, pp. 225-236, 3 figs., 2 tabs., March 2014 © 2014 by Verlag Dr. Friedrich Pfeil, München, Germany – ISSN 0936-9902 Species limits and DNA barcodes in Nematolebias, a genus of seasonal killifishes threatened with extinction from the Atlantic Forest of south-eastern Brazil, with description of a new species (Teleostei: Rivulidae) Wilson J. E. M. Costa*, Pedro F. Amorim* and Giulia N. Aranha* Nematolebias, a genus of killifishes uniquely living in temporary pools of south-eastern Brazil, contains two nominal species, N. whitei, a popular aquarium fish, and N. papilliferus, both threatened with extinction and pres- ently distinguishable by male colour patterns. Species limits previously established on the basis of morphological characters were tested using mt-DNA sequences comprising fragments of the mitochondrial genes cytochrome b and cytochrome c oxidase I, taken from 23 specimens representing six populations along the whole geograph- ical distribution of the genus. The analysis supports the recognition of a third species, N. catimbau, new species, from the Saquarema lagoon basin, as an exclusive lineage sister to N. papilliferus, from the Maricá lagoon basin, and N. whitei, from the area encompassing the Araruama lagoon and lower São João river basins, as a basal line- age. The new species is distinguished from congeners by the colour pattern and the relative position of pelvic-fin base, besides 11 unique nucleotide substitutions. The distribution pattern derived from sister taxa inhabiting the Saquarema and Maricá basins is corroborated by a clade of the seasonal genus Notho lebias, suggesting a common biogeographical history for the two genera. -

Abstract Annual fishes are found in both Africa and South America occupying ephemeral ponds that dried seasonally. Neotropical annual fishes are members of the family Rivulidae that consist of both annual and non-annual fishes. Annual species are characterized by a prolonged embryonic development and a relatively short adult life. Males and females show striking sexual dimorphisms, complex courtship, and mating behaviors. The prolonged embryonic stage has several traits including embryos that are resistant to desiccation and undergo up to three reversible developmental arrests until hatching. These unique developmental adaptations are closely related to the annual fish life cycle and are the key to the survival of the species. -

The aim of this study was to investigate the tolerance of Hypsolebias radiseriatus larvae to different salinities, and the effects of different prey concentrations and water salinities on the larviculture of this species. Salinity tolerance was tested by subjecting newly-hatched larvae to 96 hours of osmotic shock testing (experiment I) and gradual acclimatization (experiment II) of the following salinities: freshwater (control), 2, 4, 6 and 8 g of salt L-1. -

Abstract Three new species of the neotropical seasonal killifish genus Simpsonichthys are described from the middle rio Paracatu drainage of the middle rio São Francisco basin, Brazil. Simpsonichthys virgulatus is a typical member of the S. notatus species group, diagnosed by the derived A-pattern frontal squamation and presence of blue spots on distal margin of the dorsal fin in males. It is similar to S. trilineatus and S. auratus in having the anterior portion of the flanks golden, with dark brown to black blotches in males, and differs from those species by having more blotches on the flank, bars present on the caudal peduncle, and hyaline pectoral fins in males. Simpsonichthys fasciatus is similar to S. alternatus and S. delucai in having the combination of anal fin rounded in males and anal fin spatula-shaped in females, but differs in having the dorsal-fin origin anteriorly positioned and a dark gray to black stripe on the distal margin of dorsal fin in males. -
