Emended diagnosis of Xeronycteris vieirai (Mammalia: Chiroptera), with the first record of polyodontia for the genus

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 with a marked ridge, and chin with simple dermal pads and a relatively slight cleft. Additional new characters described here include anterior zygomatic arches reduced and not extending laterally and upward with respect to upper toothrow, basioccipital pits deep and separated by a high and thin bone septum, and mandible with a pronounced ridge at anterior symphysis. We propose an emended diagnosis based on morphological characters and provide a rectification on the original notation related to the holotype.

First occurrence of Lonchophylla bokermanni Sazima, Vizotto & Taddei, 1978 (Phyllostomidae) in Espírito Santo State, Southeastern Brazil

The first occurrence of Lonchophylla bokermanni Sazima, Vizotto & Taddei, 1978 in Espírito Santo state, Southeastern Brazil is reported. An adult male was caught with a mist net near an abandoned house in the Reserva Biológica de Sooretama, an Atlantic Forest preservation area in Northern Espírito Santo, in December 13th, 2008. Morphological aspects of this species are discussed. External and cranial measurements obtained for the specimen are also provided.

Lonchophylla bokermanni na Floresta Atlantica: distribuicao, conservacao e nova localidade de ocorrencia para uma especie ameacada de extincao / Lonchophylla bokermanni na Floresta Atlântica: distribuição, conservação e nova localidade de ocorrência para uma espécie ameaçada de extinção

The nectar-feeding bat Lonchophylla bokermanni has restricted distribution, being endemic in areas of Cerrado and Atlantic Forest of Minas Gerais and Rio de Janeiro, figuring in the list of endangered species of these two states. Besides being recognized as one of the five bat species endangered in Brazil. The action plan for conserving this species, proposed in 1998, cites as one of the items to the location of remnant populations and measures for their protection in the localities of occurrence. So, we report here a new distributional record of this species in Rio de Janeiro. We also include a review of its distribution area in Brazil and propose measures for its conservation in areas in the Atlantic Forest.

O morcego nectarívoro Lonchophylla bokermanni possui distribuição restrita, sendo endêmico a pequenas porções de Cerrado áreas de Floresta Atlântica dos estados de Minas Gerais e Rio de Janeiro, figurando na lista de espécies ameaçadas de extinção desses dois estados. Além de ser apontada como uma das cinco espécies de morcegos ameaçadas de extinção no Brasil. O plano de ação para conservação desta espécie, proposto em 1998, cita como um dos itens para a sua conservação, a localização das populações remanescentes e medidas que visem a sua proteção dentro das localidades de ocorrência. Sendo assim, reportamos aqui mais uma localidade para a ocorrência dessa espécie no Rio de Janeiro e fazemos uma revisão sobre sua área de distribuição no Brasil e discutimos ações para a sua conservação em áreas de Floresta Atlântica.
