| A total of 6,575 larvae in the preflexion, flexion and post-flexion stages of 15 families, 26 genera and 29 species were captured in the surf zone of Pontal do Sul beach, Paraná, Brazil. Samples of the families Gerreidae and Scianidae predominated and larvae of Eucinostomus argenteus (Baird&Girard, 1854), Micropogonias furnieri (Desmarest, 1823), Eucinostomus gula (Cuvier, 1830), Menticirrhus ameri-canus (Linnaeus, 1758) and Anchoa tricolor (Agassiz, 1829) were the most dominant species. Greater abundance of larvae was observed during the summer, followed by winter and in a less extent during spring and autumn. The number of species was greater in the summer, and there were no significant differences in the rest of the seasons. |

| A biologia reprodutiva do peixe-donzela, Stegastes fuscus Cuvier, 1830 (Perciforemes, Pomacentridae), foi estudada nos arrecifes rochosos da praia de Búzios, Nísia Floresta, Rio Grande do Norte, Brasil. Os peixes foram coletados mensalmente, medidos, pesados, dissecados, as gônadas foram removidas, pesadas e examinadas para identificação do sexo. Avaliação macroscópica dos estádios de maturação gonadal foi realizada. Um total de 549 exemplares foi capturado durante o período de outubro de 2004 a setembro de 2005. Foi registrada uma maior freqüência de fêmeas (78%), em relação aos machos (22%). Foi observado que 50% da população das fêmeas e dos machos iniciaram o processo de maturação gonadal com comprimento de 6,2 cm e 7,0 cm, respectivamente. Em relação... |

| Epilachna paenulata (Germar, 1824) was reared feeding on pumpkin leaves (Cucurbita pepo Lourt.) in laboratory conditions at temperatures of 20±0,5ºC, relative humidity of 65±0,5% and 12 hour photoperiod. Groups of fecunded and non-fecunded females were studied. The ovarioles showed four developing stages during egg production, morphologically alike for fecunded and non-fecunded females, but differing in the duration time of the stages. Each ovarium has 24 ovarioles on average, less than any other species known into the genus, and all ovarioles are physiologically active at each oviposition. The mean number of ovarioles is lower when compared with the other species of Epilachninae known. Fecunded and non-fecunded females showed a similar preoviposition... |

| Mosquitoes ecological features were studied in a preserved forest - Capão da Imbuia - placed in the urban area of Curitiba City, Paraná, Brasil. In this research were noted immature forms in artificial recipients made by different materiais. Five species were found in this recipients: Culex (Culex) acharistus Root, 1927, Culex (Culex) group coronator Dyar & Kanb, 1906, Culex (Culex) eduardoi Casal & Garcia, 1968, Culex (Culex) quinquefasciatus Say, 1823 and Toxorhynchites (Lynchiella) theobaldi (Dyar & Kanb, 1906). It's very important to know the mosquitoes that in urban area due they carry human desease agents by some species. |

| The anatomy of Cochlespira elongata, a new species from continental slope of São Paulo coast, Brazil, is described. This analysis shows some interesting characters in the foregut, with rhynchodeal walls muscular and free from the haemocoel and insertion of venom gland in mid region of the esophagus; in the osphradium, with bilobed right filaments; and in the penis, with a complex arrangement of structures in the tip. A complementary description of Cochlespira radiata (Dall, 1889a) from Florida, USA, is also given, for a better comparison between both species. |

| The mean values of hepatosomatic relation (HSR), splenosomatic relation (SSR) and relative condition factor (Kn) in Nile tilapia (Oreochromis nilolicus Trewavas, 1983); pacu (Piaractus mesopolamicus Holmberg, 1887); piauçu (Lepori-nus macrocephalus Garavello & Britski, 1988) and tambacu hybrid (P. mesopotamicus male x Colossoma macropomum Cuvier, 1818 female) are described. The experiment was carried out from feefishing farm situated in Franca, São Paulo State, Brazil. Nile tilapia showed the greatest HSR compared to pacu, piauçu and tambacu. Although, in the last three fishes the relation was similar. The SSR between tilapia and piausu was similar, but smaller than observed in pacu and tambacu. Nevertheless, SSR in pacu and tambacu was different.... |

| Temnocephala minutocirrus sp. nov., an ectosymbiont on Cryphocricos granulosus De Carlo, 1967, is described from the State of Rio Grande do Sul, southern Brazil. One hundred and nine naucorids were examined, of which 36 (33%) were positive for this species of Temnocephala Blanchard, 1849. In one sample of 94 creeping water bugs, 49 (52%) were 4th instar nymphs, 6% of which were infested; 45 (48%) were adults, either brachypterous (40 with 18 males and 22 females) or macropterous (5 with 1 male and 4 females), 67% of which were infested (29% males and 38% females). Temnocephalan eggs were found both ventrally and dorsally: fixed on coxae, trochanters, and along the sternum between fore middle, and hind pairs of legs; basal of the abdominal area; and on the... |

| Amazona vinacea (Kuhl, 1820) é uma espécie endêmica da Mata Atlântica e ameaçada de extinção no Brasil e no mundo. Não existem relatos recentes de sua presença na porção setentrional de sua distribuição ao norte do estado do Rio de Janeiro. O último é datado provavelmente de 1991, tendo sido considerado extinto ao norte do Espírito Santo. O presente trabalho noticia a redescoberta da espécie em Alto Rio Novo, noroeste do Espírito Santo, divisa com Minas Gerais. Foram registrados bandos em duas localidades em dezembro de 2005, sendo o maior deles composto por 28 indivíduos. Durante os registros foi observado A. vinacea se alimentando de Anadenanthera sp. (Fabaceae: Mimosoideae), uma nova fonte alimentar para a espécie. Os registros históricos mais recentes... |

| The embryonic development of four species of the family Palaemonidae was studied under laboratory conditions. Adults of Macrobrachium olfersi (Wiegman, 1836), Macrobrachium potiuna (Müller, 1880), Palaemon pandaliformis (Stimpson, 1871) and Palaemonetes argentinus (Nobili, 1901) were collected in Santa Catarina Island, Santa Catarina, Brazil and maintained at 26ºC. The following embryonic characters were analyzed: egg shape, yolk organization and cleavage plane, naupliar and post-naupliar appendages, stomodeum, optical lobes, eyes, telson, embryo curvature and the space occupied by the embryo in the egg. Different rates of development were observed for the four species, with M. potiuna showing the longest time of embryogenesis. The species studied followed... |

| Todos os anos milhares de aves limícolas e migratórias invernam ao longo da costa da América do Sul, entre setembro e abril, onde adquirem massa corpórea e realizam mudas para retornar aos sítios de reprodução. Estudos quali-quantitativos foram realizados na Área de Proteção Ambiental de Piaçabuçu, Alagoas, Brasil, através da contagem direta, objetivando o acompanhamento das flutuações sazonais da avifauna migrante. Foram registradas cinco espécies da família Charadriidae: Vanellus chilensis (Wagler, 1827); Pluvialis squatarola (Linnaeus, 1758); Charadrius semipalmatus Bonaparte, 1825; Charadrius collaris Vieillot, 1818 e Charadrius wilsonia (Ord, 1814) e cinco espécies da família Scolopacidae: Arenaria interpres (Linnaeus, 1758); Actitis macularius... |

| The identity of many Neotropical species of Pseudisobrachium Kieffer, 1904 is currently unreachable, mostly because the available descriptions and illustrations are not sufficiently accurate to allow precise identifications. To help solve the problem, 115 valid species and their junior synonyms were examined. Twelve nomenclatural acts are made, and 110 valid species are recognized for the Neotropical region. Two lectotypes are designated: Pristocera crassicornis Westwood and Pristocera haemorrhoidalis Westwood. Seven new species-group synonyms are proposed: Pseudisobrachium retusum Evans syn. nov. for P. pauxillum Evans; P. cunco Perez syn. nov. for P. erythrocephalum Evans; P. navajo Evans, P. rectangulatum Evans, P. emarginatum Evans and P. foutsi Evans... |

Salinity ranged between 1.0 - 37.5 at Cururuca and Paciência; 3.9 - 20.8 at Ana Jansen, and 1.0 - 32.7 in the area including Mosquitos/Coqueiro and Cachorros. No correlation between salinity and distribution of species was obtained. Genyatremus luteus was the predominant species (21.4%) followed by Mugil curema (11.6%) and Arius herzbergii (11.2%). Ariidae, Mugilidae, Sciaenidae and Engraulidae were... |
