Woodlice were reared in laboratory in the environmental climate of the city of Curitiba, Brazil, with the purpose of getting to know the process of formation of oostegites. Two kinds of cultivation were adopted: natural populations to be controlled were kept in small glass aquariums resembling the natural environment; and, new-bom woodlice were raised each one isolated in small plastic receptacles, with a special diet until two years old or over. When adults, after recognizing their sexes, males and females were put together to copulate during one or more days, and some of the females were fertilized. After 30 days, the fertilized females realized ecdise and acquired oostegites. The complete process (copulation, fecundation, incubation and birth) occurred between 25 and 50 days. The females fertilized only once produced one or more broods, each brood varying from 10 to 30 youngs. The spermatic mass reserved in the seminal receptacle depleted after having realized one, two or, rarely, three broods; the females without sperm in the receptacle realized ecdise, lost oostegites and got again virginal aspect. Females in such condition, kept alone, isolated from males have never acquire oostegites again. Otherwise, in contact with males, once fertilized they realized ecdise and acquired new oostegites. The authors have concluded that the oostegites only are formed because of the received sperm and its continuity depends on the sperm accumulated in the seminal receptacle, for more than one brood.

Hexapanopeus heblingi sp.n. is described in base of an adult male reared in the laboratory. This species of crab is typic of Anchieta Island, Ubatuba (23o32'S and 45o05'W), North coast of São Paulo State, Brazil.

Due to its biogeographical characteristics. the coast of the State of Paraná reveals to be a very important area for zoological researches. At the present time, however, there are only a few studies related to its carcinological fauna. The Museu de História Natural Capão da Imbuia which belongs to the Curitiba City Hall and the Centro de Estudos do Mar, of the Universidade Federal do Paraná have Crustacea collections, which are the unique references to the State. This research paper was based on the files of these institutions and also on bibliographical survey. The present research contains a detailed report of the collections and a catalogue of Dendrobranchiata and Caridea (Crustacea) species, including typical locality and geographical distribution of them.

Qualilative and quantitative studies of Isopoda species were made at Mundaú/Manguaba Estuary-Lagoon Complex on the Coast of Alagoas State. Six points were established in order to carry out methodical collections of animals. These collections were made monthly, without interruption, from April, 1990 to March, 1991, in which three families, five genera and seven species of Isopoda were identified. A special key for identification of Isopoda and also diagnosis for each species are presented. Sphaeromatidae Family was the most significant and Cassidinidea fluminensis (Mane-Garzón, 1944), was the species with numerical dominance. Space/time distribution of the species of Isopoda was related to the variation of salinity.

A concise description and a latitudinal distribution to South Brazil of Calappa sulcata are presented.
