Ocorrência de Glyphonycteris sylvestris Thomas (Chiroptera, Phyllostomidae) no Estado do Rio de Janeiro, sudeste do Brasil Occurrence of Glyphonycteris sylvestris Thomas (Chiroptera, Phyllostomidae) in Rio de Janeiro State, Southeastern Brazil

<abstract language="eng">The first occurrence of phyllostomid bat Glyphonycteris sylvestris Thomas, 1896 in Rio de Janeiro State, Southeastern Brazil is reported. An adult female was caught with mist net in the Parque Estadual da Pedra Branca, an AtlanticForest area in West Zone of Rio de Janeiro city, in July 9th, 1996. Morphological aspects of this species are discussed. Measurements obtained for the specimen are also provided

Notes on the lesser white-lined bat, Saccopteryx leptura (Schreber) (Chiroptera, Emballonuridae), from southeastern Brazil

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 craniodental selected measurements, specimens from Rio de Janeiro were close to the upper limits of the ranges known for the species

Systematics of the Pacific monkey-faced bats (Chiroptera : Pteropodidae), with a new species of Pteraloplex and a new Fijian genus

Copyright © 2005 The Natural History MuseumThe fruit-bat genus Pteralopex comprises the monkey-faced bats, a group of six endangered species found only in old-growth forests on certain islands in the south-west Pacific (the Solomon Islands and Fiji). The taxonomy of the genus is reviewed in detail and updated accordingly. Two ‘cryptic’ biological species are shown to occur in sympatry on both Bougainville and Choiseul in the northern Solomon Islands (corresponding to Pteralopex anceps Andersen, 1909 and a previously undescribed species) and each is accordingly described and reviewed. A new genus (Mirimiri) is erected for the Fijian monkey-faced bat (formerly Pteralopex acrodonta), which differs greatly both morphologically and genetically from species of Pteralopex in the Solomon Islands. Ecomorphological differences between sympatric Pteralopex species are briefly reviewed, including potential differences in functional morphology and feeding ecology. Geographic patterns of occurrence and future survey priorities for monkey-faced bats are also discussed.Kristofer M. Helge
