Significance of the sexual openings and supplementary structures on the phylogeny of brachyuran crabs (Crustacea, Decapoda, Brachyura), with new nomina for higher-ranked podotreme taxa.
The penial area proves to be an essential diagnostic feature in Brachyura, with a value comparable to that of the gonopods, and trends towards the coxo-sternal condition are exemplified by multistate characters, varying from a shallow depression to a long groove along expanded sternites 7 and 8, and ultimately their complete, extended junction typifying the most derived coXo-Sternal condition.

A new theoretical approach for the study of monophyly of the Brachyura (Crustacea: Decapoda) and its impact on the Anomura
The argument is made that there are four different assumptions hidden within this question, and that only when they are explicitly considered will real progress be made towards a better understanding of brachyuran interrelationships. Expand
A new subfamilial arrangement for the Dromiidae de Haan, 1833, with diagnoses and descriptions of new genera and species (Crustacea, Decapoda, Brachyura)
Une revue de diverses dispositions morphologiques chez les Dromiacea (et plus largement chez les Podotremata) a revele que la classification actuelle des Dromiidae ne refletait pas la richesse desExpand
Alien Decapod Crustaceans in the Southwestern Atlantic Ocean
Thirteen marine alien species of decapod crustaceans have been recorded from the Southwestern Atlantic. Five species of alien decapods have established local populations: Charybdis hellerii (Brazil),Expand
New species and new records of deep-water caridean shrimps from the South Atlantic Ocean (Crustacea, Decapoda)
Une nouvelle espece d'une crevette caride de profondeur est decrite de l'Atlantique sud-occidental, Heterocarpus inopinatus n. sp. (Pandalidae). La nouvelle espece se distingue aisement desExpand
Taxonomic sufficiency for soft-bottom sublittoral mollusks assemblages in a tropical estuary, Guanabara Bay, Southeast Brazil.
The literature about taxonomic sufficiency has demonstrated that faunal patterns at different taxonomic levels tend to become similar with increased pollution, and in Guanabara Bay, an analysis carried out solely at family level is perfectly adequate to describe the ecophysiological stress. Expand
The cruise of the Marion Dufresne off the Brazilian coast : account of the scientific results and list of stations : Brazilian deep water fauna : Results of the oceanographic cruise TAAF MD55
Le Marion Dufresne a realise une serie d'echantillonnages dans les eaux profondes au large du sud-est bresilien : campagne oceanographique TAAF MD55/Bresil. Expand
Population structure of the lancelet Branchiostoma caribaeum (Cephalochordata: Branchiostomidae) in the Baía de Guanabara, Rio de Janeiro, southeastern Brazil
Population structure of the lancelet Branchiostoma caribaeum Sandevall, 1853 was studied in four surveys, corresponding to austral seasons, in a tropical bay, southeast of Brazil, suggesting continuous breeding that is typical of tropical species. Expand
Echinoidea and Holothuroidea (Echinodermata) of the Trindade and Martin Vaz Archipelago, off Brazil, with new records and remarks on taxonomy and species composition
The Brazilian oceanic islands are impoverished oceanic outposts of the Brazilian Province; nevertheless, endemic species and intraspecific morphological variations compared with the mainland suggest they may also be regions of speciation. Expand
