Emended diagnosis of Xeronycteris vieirai (Mammalia: Chiroptera), with the first record of polyodontia for the genus Rev. Bras. Zool.
Nogueira,Marcelo R.; Gregorin,Renato; Peracchi,Adriano L..
The Caatinga-endemic nectar-feeding bat, Xeronycteris vieirai Gregorin & Ditchfield, 2005 was described based on four specimens. Since then, only two additional specimens have been reported in the literature. Examination of a new specimen that closely agrees with the original description but presents two additional upper premolars, led us to review the type series of this taxon. Our analysis provided support to the recognition of the new specimen as a X. vieirai with supernumerary teeth and revealed new diagnostic characters that can help in the field identification of this species. Xeronycteris vieirai presents tricolored dorsal fur, entirely naked forearm, connection of the base of the spear of the noseleaf with the upper limit of the horseshoe...

Notes on the lesser white-lined bat, Saccopteryx leptura (Schreber) (Chiroptera, Emballonuridae), from southeastern Brazil Zoologia
Nogueira,Marcelo R.; Peracchi,Adriano L.; Pol,André.
Saccopteryx leptura (Schreber, 1774) is reported from two new localities in southeastern Brazil, both in Atlantic forest remains in the state of Rio de Janeiro. Analysisof food material showed that individuals from both localities had preyedon insects in the order Hymenoptera. Cheek contents were available from one specimen, and in this case identification of the food item (flying ants) achieved generic level (Pheidole Westwood, 1841). Aspects in the social behavior observed in a colony suggest that the same traits documented in Central American populations (small colonies, monogamic mating system, and retention of young for up to a year in the parental unit) may also characterize this species in the southern most part of its range. In both external and...

New records of Uroderma magnirostrum Davis (Mammalia, Chiroptera) from southeastern Brazil, with comments on its natural history Zoologia
Nogueira,Marcelo R.; Tavares,Valéria C.; Peracchi,Adriano L..
Uroderma magnirostrum Davis, 1968 is reported from four new localities in southeastern Brazil, significantly extending its geographical distribution south and westward. A total of 12 adult specimens collected in areas of Caatinga and Atlantic Forest in the states of Minas Gerais, Espírito Santo, and Rio de Janeiro, including specimens from the new localities and museum specimens were examined. Females from southeastern Brazil were larger than males in all external measurements analyzed, but after univariate statistical analyses using corrected p values for multiple tests no significant sexual dimorphism was detected. Mean values obtained from this sample fall within the known range documented for the species in both external and cranial measurements, and...

Primeiro registro da família Furipteridae (Mammalia, Chiroptera) para o Estado do Rio de Janeiro, Brasil Zoologia
Pol,André; Nogueira,Marcelo R.; Peracchi,Adriano L..
Furipterus horrens (Cuvier, 1828), the only species in the family Furipteridae known to occur in the Brazilian territory, is reported for the first time in the state of Rio de Janeiro. The single specimen obtained was found alone in its diurnal roost in a cavity formed among large granite blocks in a well-preserved Atlantic Forest area. Morphometric data obtained from this specimen are within the known range documented for the species.
Tipo: Info:eu-repo/semantics/other Palavras-chave: Distribution; Furipterus horrens; Southeastern Brazil.
