The larvae of Lestes bipupillalus Calvert, 1909 and Lestes tricolor Erichson. 184S are described and illustrated based on specimens collecled in têmporary habitais near the city of Rio de Janeiro. Additional information are given on the morfology of the larva of Lestes pictus Hagen, 1862 and a key for the identification of the brazilian speeies of Lestes whose larvae are known. is presented.

Coremia (Dirocoremia), subgen.n.. is proposed for Coremia ingae, sp.n.. from Paraná. Brazil (type species) Coremia bruchi Gounelle, 1905 and Coremia simpiicipes Gounelle, 1911.

The time of full stomach repletion and fat condition was determined through an analysis of the average stomach repletion index, condition faclor and relative frequency of repletion for different periods of the year. Condition factor was influenced by weight gain in the stomaches, main from April to June.

This species showed feeding activily ali year long. Although zooplancton, protozooplancton and other organisms have been found in the stomaches, this species can be considered, broadly speaking, herbivorous since a great amount of seaweed was found in its diet. Fulness of the stomachs was not associated with sex difference. Full stomachs were found throughout the period. Variations according to the estimated periods were not found.

Described herein is a case of alhinism in lhe Peccary Tayassu tajacu Linnaeus. 1758 (Artiodaclyla. Tayassuidae). which was observed in Colônia Castelhanos. São José dos Pinhais. Paraná, in lhe Southern Bra/il. The specimen was caplured when very young. The normal peccary (Tayassu tajacu) is a dark-gray animal wilh a while hand across the ehest from shoulder Io shoulder. This animal have while skin. hlued eyes bul has pigmented feet.

Are describcd a new genus, and a new species, including characteres of the wing venation, moulh pieces, proendosternite, metendosternite and ovipositor. This species has a restrict geographical distribution in Espírito Santo and Bahia - Brazil.

A new technique to reliably estimate true tadpole abundance in small ephemeral forest ponds based on a sample taken from a bottom net is presented. The bottom net is placed in the pond before it fills with water. At given intervals the bottom net is lifted through the water column and all tadpoles can be counted. Based on a series of calibrations, the technique showed significant correlations between estimated abundance of Osteocephalus taurinus Steindachner, 1862, Colostelhus marchesianus Melin, 1941, Phyllomedusa tomoptema Cope, 1868, and aeshnid larvae, and true abundances based on total counts.

This isthe fifth fascicle of the series and deals with the polychaete families Psionidae, Chrysoptelidae, Aniphinomidae e Euphrosinidae whieh are represented in the Brazilian coast respectively hy 1,5, 9 and 2 species. The speciniens of ali the species examined are deposited in the Collection of the Departamento de Zoologia, Instituto de Biologia of the Universidade Estadual de Campinas (UNICAMP), Campinas, São Paulo.

In the present paper the authors describe and illustrate a new species of proteocephalidean cestode, Monticellia belavistensis, sp.n., parasite of a freshwater siluriform fish (thorny catfish). Pterodoras granulosus (Valenciennes, 1833), from the Itaipu Reservoir and Paraná River, in the region of Porto Rico. This is the first reference of a proteocephalid in this host. The values of prevalence and mean intensity of infection are given and the life cycle is discussed.

Semperula tailandensis, sp.n. from Salaya, Nakhon Patom Province, Tailand, is described upon a sample of 35 specimens, deposited on the collection of the Museu de Ciências Naturais da Fundação Zoobotânica do Rio Grande do Sul, Nr. 33125, holotype and Nr. 33126, paratypes. Detailed morphological and anatomical characters as well quantative data are given.

Aspects of reproduction of Rineloricaria latirostris Boulenger, 1899 of Passa Cinco river (Ipeúna, São Paulo) were investigated during 18 months. The spawing period was determined by the analysis of the maturation curve, based of the monthly variation of the gonadosomatic index and condition factor. The size and age on the maturation and fecundity were also determined. The fecundity was realted to some parameters such as total length and total weight.

Ennya scaramozzinoi, sp.n. from Ecuador, Calloconophora dietrichi, sp.n. and Amastris deitzi. sp.n., both from Mato Grosso, Brazil, are described.

This work deals with feeding tests performed in laboratory with Pantopoda species, Tanystylum isabellae Marcus, 1940 and Anoplodactylus stictus Marcus, 1940. Animals (alive and dead) and vegetable foods were offered to males without eggs, males with eggs, females and juveniles Pantopoda. Of the 13 types of food offered to the animals only Sertularia Linnaeus, 1758 (Hydrozoa). Amathia distans Busk, 1886 (Bryozoa), Hyale media (Dana, 1853) (Crustacea, Gammaridea), Caprella danilevskii Czerniavski, 1868 (Crustacea-Caprellidae), Artemia salina Leach, 1812 (Crustacea, Anostraca) e Perna perna (Linné, 1758) (Bivalvia, Mytilidae) were actually eaten. The macroalgae Sargassum C. Agardh, 1820; Padina Adanson, 1763; Chaetomorpha Kützing, 1845 and Ulva Linnaeus. 1753, the Hydrozoa Dynamena (Linnaeus, 1758), Polychaeta aixl anemon fragments weren't accepted.

Skin to lung migration of Schistosoma mansoni Sambon, 1907 - (75 Se) - selenomethionine-labeled cercariae was tracked by tissue autoradiography on days 1, 4, 6, 8 after challenge, in rabbits immunized with a S. mansoni derived saline extract. Either in vaccinated animals or in those of the control unprimed group, the peak of skin schistosomula occurs 24hs after infection. Comparison between peaks of lungs migrating larvae showed that, in control animals, the increase of worm burden in this site, is detected on the 6th day post-infection, differing from immunized rabbits, in which this peak occurs on day 4, when skin and lungs counts are still equivalent, decreasing gradually, showing a different pattern of the S. mansoni migration and suggesting that main parasite attrition occurs during the late skin and early lung phases in the immunized group.

Myrciariamyia bivalva, gcn.n., sp.n. associated with Myrciaria Jloriburula (Myrtaceae), in Brazil, is deseribed and illustraled (larva, pupa, male, female and gall).

At Guaraluba bay, the catfish Genidens genidens shows incubating behavior during the summer months. The larvae are either less or heavier than the eggs, and their stomach analysis confirms the exogenous leeding during incubation. Embryos sizes can increase to 59mm in total lenght and 2,8g in total weight, including the yolksac. It was observed that the largest larvae are guarded by the largest adults, and that the embryo size is similar among individuals from the same adult.

In this paper, female Macrobrachium carcinus (Linnaeus, 1758) maturation curve, weight/length relationship, length and weight growth curves were studied. Prawns were captured, by traps, in Ribeira de Iguape river (24ºS and 47ºW), southern Brazil. There were used 207 females. It was observed that M. carcinus presents several spawnings during its life cycle and reproductive period goes on, at least till six years old. Weight/length relationship can be represented for the equation W = 8.73 E-3 L3.28. Expressions obtained for length and weight growth curves are Lt = 21 .0 (1-e-0493t) and Wt= 190 (1-e-0493t)3.28. respectively. A symptotic maximum length and asymptotic maximum weight are nearly attained at six and eight years old, respectively.

The influence of a diet based on putrid horse meat over the post-embryonic development of Cochliomyia macellaria (Fabricius, 1775) under controlled conditions (UR 65 10% and 14 hours of photophase) was compared with the results obtained using a meat broth diet to which other sources of animal and vegetable protein were added. The flies were maintained at 30ºC, from egg until mature larvae spontaneously abandoned the diet. They were then transfered to a climatized chamber at 27ºC. The larvae and pupae viability and the weight of the mature larvae were significantly inferior, when a diet based on meat broth was used, even though the larvae period was significantly increased with this diet. This type of diet did not charge the time of development of the pupae. The inoculation of the egg mass directly over the diet was recommend, instead of the technique in which the egg masses are transfered to humid filter paper, followed by the handling of the recently ecloded larvae.
