Some bat species are able to adapt to urban areas, where they find food and roosts. Despite the high number of parks in Brazilian cities, they did not yet raise the interest of most zoologists, except for some surveys of birds and butterflies. The objectives of the present study were: (i) to inventory the bat species of Quinta da Boa Vista (QBV), a large (25 ha) urban park centrally located in densely populated Rio de Janeiro, which is Brazil's second largest metropolis; (ii) to compare the species richness observed in roosts with the richness recorded through mist netting in flight routes and near fruiting fig trees; and (iii) to analyze recaptures of bats marked in this park and recaptured in other sites and vice-versa. Sampling totaled 104 sampling nights resulting in 3,256 captures (including 133 recaptures) between April 1989 and December 2004. We also sampled roosts and received some specimens from park visitors and city workers. We documented 21 bat species, predominantly large frugivores. The number of expected species for this park was 24.0 ± 4.6, and the total sampled represented 87.5% of the expected. The recapture of bats marked in surrounding forest fragments and in QBV shows the importance of urban parks for the maintenance of bat diversity. Inspection of roosts produced two species that had not been captured with other methods. Sampling near fruiting fig trees did not differ in terms of richness from sampling carried out far from these trees or during their non-fruiting periods.

Polychromophilus deanei n. sp. (Haemosporidiidea, Haemoproteidae) is described from a vespertilionid bat, Myotis nigricans nigricans (SCHINZ, 1821), captured on the Rio Maracapuçu, Município of Abaetetuba, Pará, Brasil. Mature oocysts were found in 2 specimens of the ectoparasite Basilia sp., taken form the infected animal. The parasite is probably the same as that previously described in another bat, Glossophaga soricina soricina, from the same general area, by DEANE & DEANE in 1961.

Cell surface proteins of Trypanosoma dionisii, Trypanosoma vespertilionis and Trypanosoma sp. (M238) were radiodinated and their distribution both in the detergent-poor (DPP) and dertergent-enriched phase (DRP) was studied using a phase separation technique in Triton X-114 as well as polyacrylamide gel electrophoresis in sodium dodecyl sulphate (SDS-PAGE). Significant differences were observed in the proteins present in the DRP when the three species of trypanosoma were compared. Two major bands with 88 and 70 KDa were observed in T. sp. (M238) but were not detectable in T. dionisii and T. vespertilionis. Three polypeptides whith 96, 77 and 60 KDa were identified in the DRP of T. vespertilionis. Three major bands with 84, 72 and 60 KDa were observed in the DRP of T. dionisii. Two polypeptides with 34-36 KDa present in the DPP, were observed in the three Trypanosome species analyzed. Our observations show that T. sp. (M238) has characteristic surface polypeptides not found in T. vespertilionis.
