| A study of phylogenetic relationships of the genera of Mesembrinellinae and of the species of Eumesembrinella Townsend, 1931, on the ground of shared derived character states (synapomorphies) is presented. Resulting the following assumption: Laneella Mello, 1967 presenting sister group relationship with all other Mesembrinellinae, followed by Souzalopesiella Guimarães, 1977, M. peregrina Aldrich, 1922 that was isolated from Mesembrinella Giglio-Tos, 1893. Mesembrinella was considered paraphiletic, its species were judged in changeable positions at the bifurcation point of analysis of Albuquerquea Mello, 1967 with the tricotomic interrelationships of Thompsoniella Guimarães, 1977, Huascaromusca Townsend, 1918 and Eumesembrinella Townsend, 1931. The... |

| This paper describes morphological characteristics of the ovarian germinative cells of the Scinax fuscovarius (Lutz, 1925). The ovary is organized in primordial germinative cells (oogonia) and follicular structures (ovarian follicle) - oocytes surrounded by follicular cells. Oogonia: their nests are peripherically localized, containing cells with large and oval nucleus. Oocytes I: basophilic cytoplasm; the spherical nucleus presents few nucleoli, one or two; the follicular cells (one tenuous layer) surround these previtellogenic cells. Oocytes II: the cell is larger and the cytoplasm becomes more basophilic; the nucleus presents few nucleoli and contains many chromosomes in the periphery (beginning the perinucleolar stage). Oocytes III: the cytoplasm... |

| We record here the occurrence of seeds of several plant species in feces found inside the day roost of Chrotoperus auritus, at the Estação Experimental de Itirapina, State of São Paulo, Southeastern Brazil, in July 2001. The roost was used by only one adult female, non pregnant, during about a month. In the feces, fur of rodent (Muridae), bone fragments, fragments of Scarabaeidae and other beetles and insects, leaves (not determined) and many seeds of Piperaceae (Piper sp.), Urticaceae (Cecropia sp.) and Solanaceae (Solanum spp. and Cestrum sp.) were found. In the gut content, insect fragments, fur of rodent (Muridae) and plant remains were found. It was discussed why this carnivorous bat would be consuming plant items. |

| Nosferattus gen. nov., Capeta gen. nov. and Amatorculus gen. nov. are proposed from North and Northeastern Brazil. Due to the absence of teeth on the retromargin of the chelicerae, these genera are included within the Sitticinae, and are probably related to the genus Aillutticus Galiano, 1987, with which they share a high, broad carapace, rounded laterally behind the posterior lateral eyes, and the cephalic region slightly convex. Nosferattus is proposed to include five species: the type species Nosferattus discus sp. nov. and Nosferattus ciliatus sp. nov. from Maranhão, Nosferattus aegis sp. nov. from Tocantins, Nosferattus occultus sp. nov. from Maranhão and Ceará, and Nosferattus palmatus sp. nov. from Sergipe. Capeta and Amatorculus are both monotypic... |

| The toninha, or franciscana, Pontoporia blainvillei (Gervais & D'Orbigny, 1844), is an endemic species of cetacean of the southwestern Atlantic Ocean. There is little information on the occurrence of this species in its natural environment due to the great difficulty in sighting it. Systematized and non-systematized observations of franciscanas were made from December 1996 through November 2001 at Babitonga Bay, on the northern coast of Santa Catarina State, southern Brazil. The observations were made from small motorboats. A total of 79 observations were made, totaling 561 individuals. Up to 59.5% of the groups consisted of over four individuals and the average group size was seven. Calves were present in 30.4% of the observations. The species was... |

| Type specimens of some of Caporiacco's Neotropical species are revised. The taxonomy of his species from French Guiana, whose type specimens are lost, is considered. The types of Corythalia hadzji Caporiacco, 1947, Corythalia luctuosa Caporiacco 1954, Hypaeus barromachadoi Caporiacco, 1947 and Naubolus melloleitaoi Caporiacco, 1947 are redescribed.The following new synonymies are established: Freya guianensis Caporiacco,1947 = Chira spinipes (Taczanowski, 1871) syn. nov.; Hypaeus bivittatus Caporiacco, 1947 = Hypaeus barromachadoi Caporiacco, 1947 syn. nov. New combinations are:Agelista petrusewiczi Caporiacco,1947 = Noegus petrusewiczi (Caporiacco,1947) comb. nov. .;Albionella chickeringi Caporiacco, 1954 = Mago chickeringi (Caporiacco,1954) comb.... |

| Along ten years of study of a common dolphin from the brazilian coast, Sotalia brasiliensis Van Beneden, 1874, I could see some occasions of feeding associations of this dolphin with five species of birds, Sula leucogaster (Boddaert, 1783), Fregata magnificens Mathews, 1914, Sterna hirundinacea Lesson, 1831, Larus dominicanus Lichtenstein, 1823 and Phalacrocorax olivaceus Humboldt, 1895. The commonest association observed was between the dolphin and S. leucogaster, and in all the associations was characterized the commensalism, with advantaged to the birds. |

| From 126,340 adult specimens of Trichoptera captured with light trap during one year of the project called "Survey of the Entomological Fauna in Paraná State" (Paraná, Brazil), 6,375 belong to the family Leptoceridae. The individuals of the family were identified and a list of species is presented. The following species are recorded for the first time to Paraná State: Achoropsyche duodecimpunctata (Navas. 1916); Nectopsyche aureovittala Flint, 1983; Nectopsyche fuscomaculata Flint, 1983; Nectopsyche muhni (Navas, 1916); Nectopsyche separata (Banks, 1920); Nectopsyche ortizi Holzenthal, 1995; Nectopsyche splendida (Navas, 1917) and Tripleclides gracilis (Burmeister, 1839). Discussion on individual abundance and species seasonality are also presented. |

| Panurgillus, a generic name used by J.S. Moure throughout various years in litt. as a substitue of Panurginus in the Neotropical Apifauna, is formally described. All specimens of the species here described were collected during surveys of bees and melittophilous plants in th state of Rio Grande do Sul, southem Brazil. Various species of Panurgillus also occur in other states of southem Brazil, in Argentina and probably in Uruguay, Paraguay and Eastem Bolivia. The bees are small (3,9-7,4 mm), black, with generally a few yellow paintings, two submarginal cells, the lst m-cu distant to the base of the second submarginal cell, the clypeus not projected, the facial foveae distinct, scopa with simple, long hairs and the gonobase absent. Panurginus vagabundus... |

| Este estudo segue um trabalho prévio sobre o levantamento taxonômico dos tintininos (Subordem Tintinnina) coletados em águas subtropicais do sul do Brasil (22°S-34°S). As amostras foram baseadas em diferentes cruzeiros oceanográficos cobrindo águas de plataforma e oceano. As espécies pertencentes às Famílias Dictyocystidae, Rhabdonellidae, Tintinnidae e Xystonellidae foram descritas, e uma discussão geral referente à biogeografia de tintininos e à distribuição vertical na coluna de água observada em cruzeiros oceanográficos foi realizada. Para todas as espécies foram fornecidos descrições, medidas e desenhos, bem como comentários sobre a taxonomia e resultados sobre as distribuições horizontal e vertical na coluna de água. A riqueza em espécies foi elevada... |

| The bay of the Tibagi river, a place which goes through quick environmental alterations, has three forest fragments: the "Floresta Nacional do Irati" (3.572 ha), the "Reserva Biológica da Klabin" (11.116 ha) and the "Parque Estadual Mata dos Godoy" (680 ha). Here, Myotis ruber (E. Geoffroy, 1806) and Chiroderma doriae Thomas, 1891 can be found, these are threatened bats, and three species, Pygoderma bilabiatum (Wagner, 1843), Myotis levis (I. Geoffroy, 1824) and Rogheessa tumida H. Allen, 1866, which are presumably threatened. Using the same effort of capture in the three places, it was stated that the "Floresta Nacional do Irati" with low vegetation diversity, showed nine species of bats. The "Parque Estadual Mata dos Godoy", although it's five times... |
