| 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... |

| Temnocephala trapeziformis sp. nov., ectosymbiont on Trichodactylus fluviatilis Latreille, 1828 is described from the State of Rio Grande do Sul, southern Brazil. Sixty-eight crabs were examined, of which 61 (89.7 %) were positive for this species of the genus Temnocephala Blanchard, 1849. Eggs, as well as adult and young specimens, were found on the pleural areas of the carapace, in the orbital cavities, and, usually, on the fourth pair of pereiopods. The temnocephalans were always devoid of body pigmentation, although they kept the red eye pigment, undiluted in specimens fixed by hot (90ºC) phosphate buffered 10% formalin. The most distinctive characters of the new species are: 1) the shape and size of the cirrus and the characteristics of its introvert... |

| A new species of titi monkey, Catticebus, is described based on five specimens obtained from the state of Sergipe, north-eastern Brazil. It is a member of the Personatus group, but is easily distinguished from the other forms. The most noticeable differences are in the pelage coloration, the forehead, crown, and ear being black, and having a zebra-like, striped pattern on the anterior half of the back. Distinct features of its dental morphology and craniometry are also described. |

| Nests of the "Scaly-headed parrot" and "Illiger's macaw" - Pionus maximiliani (Kuhl, 1820) and Ara maracana (Vieillot, 1816) - found at the Ecological Station in Gália, São Paulo with clutches in 26-VII-90 and 20-IX-90, both containing four white rounded and at one end slightly pointed eggs, measuring 33.4x30.0mm and 33.0x28.0mm each respectively, are being reported on. The incubation in the "Scaly-headed parrot" lasted for 26 days, the stay of the young in the nest cavity for about 50 days and only one adult was seen incubating, while in "Illiger's or Blue-winged macaw" both parents used to stay in the nest. |

| Flacopimpla was described with one species, F. varelae by Gauld (1991) from Costa Rica (only females, Guanacaste National Park). This genus is recorded for the first time in Brazil and a new species, F. sulina, is described and the distribution in southeast and south of Brazil is mapped (Minas Gerais: Belo Horizonte; Paraná: Telêmaco Borba, Ponta Grossa, Curitiba, Colombo, Antonina). |

| A contribution to the knowledge of the social organization of a population of Golden-rumped or Black-lion tamarin (L. chrysopygus) living in a stripe of natural vegetation in the State Park along the banks of the lower Paranapanema River, in the State of São Paulo, Brazil. Its composition and analysis based on captured groups, number of individuals and their distribuition in the area with concentrations; exchange of adults males, migration of individuals from groups and females home range establishment, indicate an organization which is likely to be matrilinear. The average number of individuals per group or expanded families, in the seven (7) captured groups was 3,57 specimens with a mean body weight in adults of 572,5 grams. In each group there is... |
