Elaborou-se uma chave ilustrada, baseando-se na comparacao de caracteristicas morfologicas e morfometricas dos estadios iniciais, quando as larvas ainda sao encontradas no plancton, a deriva no rio. A chave possui a descricao das cinco principais especies utilizadas economicamente no Pantanal: pacu (Piaractus mesopotamicus), curimbata (Prochilodus lineatus), dourado (Salminus maxillosus), piavucu (Leporinus macrocephalus). As especies pintado (Pseudoplatystoma corruscans) e cachara (Pseudoplatystoma fasciatum), por nao apresentarem nenhuma diferenca nas caracteristicas utilizadas nas descricoes, foram incluidas em Pseudoplatystoma sp. As descricoes foram feitas a partir de amostras obtidas em condicoes artificiais. |

Background: Cymothoa frontalis Milne Edward, 1840 is a very poorly described cymothoid, notwithstanding the previous redescription of the female. Pertinently, to date, the host of C. frontalis has not been identified with adequate precision. Most of the descriptions of cymothoids carried out hitherto were based primarily on females, but practically ignoring other life cycle stages. The present paper redescribes the female and describes other life cycle stages of the species C. frontalis to get better precision in their identification. Results: The female phase of C. frontalis is redescribed according to type specimens extant in the NMNH, Paris, and also by the data obtained from live specimens collected during the present study. The general morphology and... |

Fourteen species of shrimps belonging to four genera of the family Atyidae are reported from the Fiji Islands. Three genera are represented by only one species each: Antecaridina lauensis (Edmondson, 1935), Atyoida pilipes (Newport, 1847) and Atyopsis spinipes (Newport, 1847) while the fourth, Caridina is represented by eleven species (including one new, Caridina devaneyi spec. nov. which is described and illustrated). Keys are provided to separate the genera and species. Two species, Caridina japonica De Man, 1892 and C. longirostris H. Milne Edwards, 1837 are recorded from Fiji for the first time. C. devaneyi spec, nov., C. fijiana Choy, 1983 and C. nudirostris Choy, 1984 are so far known only from Fiji and may be endemic to the island of Viti Levu. All... |

The present paper constitutes an introduction to taxonomic methodology. After an analysis of taxonomic practice, and a brief survey of kinds of attributes, the paper deals with observation, description, comparison, arrangement and classification, hypothesis construction, deduction, model, experiment, abstraction, and synthesis. The methodological aspects of the species-concept and of biological classification are dealt with in two final sections. |

In this publication a revision is given of the genera of the subfamily Bulimulinae (Gastropoda, Pulmonata, Bulimulidae). The morphological variation of the shell, radula, pallial organs and genitalia is analized and 21 character transition series are recognized. In the systematical part the following data are presented for each genus : description of shell and anatomy, distribution, ecology, bibliography and a list of taxa. The number of (sub) genera is reduced from 80 to 43 ( + two nomina inquirenda). A new synonymy is : Paracochlea Hylton Scott, 1967 = Eudioptus Albers, 1860. The following new species names are introduced : Bostryx sophieae, Drymaeus (Drymaeus) marcapatensis, Drymaeus (Drymaeus) sophieae, Drymaeus (Mesembrinus) pseudobesus. Berendtia... |
