Eptesicus taddeii sp. nov. Holotype.— Adult male: skin and skull with the following tags: / Holotype, Eptesicus taddeii Miranda; Bernardi & Passos det. 2006 /. /Coletor: Miranda, J. M. D. et al.; Provenance: São Luiz do Purunã, Balsa Nova, Paraná, Brasil; date: 22.XII. 2005 /. / DZUP 246 /. Deposited in the Mastozoological collection of the Universidade Federal do Paraná, Departamento de Zoologia, Setor de Ciências Biológicas, Universidade Federal do Paraná, Curitiba, Paraná, Brazil. Paratypes.— 12 females, collected in the same location and by the same collectors as the holotype, and deposited in the same collection under the following collection numbers: DZUP 247, 253, 254, 256, 257, 258, 259, 260, 261, 262, 265 and 266. Seven adult males, collected in the same location and by the same collectors as the holotype, and deposited in the same collection under the following collection numbers: DZUP 229, 248, 249, 250, 251, 252 and 255. An adult male, collected in Cerro Azul, State of Paraná, by I. S. Arnoni were deposited in the same collection under the collection number DZUP 0 98. Two females, collected in Passos Maia, State of Santa Catarina, by J. M. D. Miranda and M. F. M. Azevedo-Barros, were deposited in the same collection as the holotype under the collection numbers DZUP 263 and 264. A female, collected in Ribeira do Iguape, State of São Paulo, was deposited in the mastozoological collection of the Museu de Zoologia da Universidade de São Paulo, São Paulo, Brazil, under the collection number MZUSP 26455. The skins and skulls were deposited separately, with the skins preserved in 70 % ethanol. Type locality.—Fazenda Monjolo, District of São Luiz do Purunã, Municipality of Balsa Nova, State of Paraná, Southern Brazil (25 º 26 ’ 58 ” S and 49 º 41 ’ 51 ” W). Etymology. – The species name is a homage to Prof. Dr. Valdir Antônio Taddei in recognition of his great contribution to the study of Neotropical bats. Distribution.— Eptesicus taddeii sp. nov. is hitherto known to occur in the Southern and Southeastern of Brazil. The occurrence records are from: District of São Luiz do Purunã (25 º 26 ’ 58 ” S and 49 º 41 ’ 51 ” W), Municipality of Balsa Nova, State of Paraná; State Park of Campinhos (24 º 49 ’ 25 ” S and 49 º 15 ’ 40 ” W), Municipality of Cerro Azul, State of Paraná; Municipality of Passos Maia (26 º 46 ’ 48 ” S and 52 º03’ 34 ” W), State of Santa Catarina, and locality of Barra do Ribeira (24 º 42 ’ 29 ” S and 47 º 33 ’ 19 ” W), Municipality of Iguape, State of São Paulo. This species appears to occur in the Atlantic Rainforest sensu lato, with most of the occurrences being included in Araucaria Pine Forests (Figure 3). Remarks.— The species was captured using mist nets (6 x 2.5 m, 7 x 2.5 m, and 9 x 2.5 m), which were set up 0.5 m above the ground. Eptesicus taddeii sp. nov. was active all night, with captures from 6: 30 PM to 5: 40 AM. Captures occurred both in primary forests and in regenerating forests and forest edges. It appears to be an insectivore, as in the case of most members of the Vespertilionidae family. In addition to the new species, Eptesicus brasiliensis and E. furinalis were collected in the type locality, in syntopy. Given the high level of morphological similarity between Eptesicus taddeii sp. nov. and E. brasiliensis, it is likely that specimens of E. taddeii sp. nov. are presently misidentified in zoological collections as E. brasiliensis. In fact, this was shown to be the case in an analysis of the specimens MZUSP 26455, DZUP 0 98 and 229, which were inspected during this study and shown to belong to the new species. A broad revision of the genus might increase the currently known distribution of E. taddeii sp. nov.Published as part of Miranda, João M.

The taxonomic status of Myotis levis levis and Myotis levis dinellii (Mammalia: Chiroptera: Vespertilionidae)
Investigating the Myotis levis complex is important for understanding the taxonomic status of the two subspecies currently recognized in it: Myotis levis levis (I. Geoffroy, 1824) and M. levis dinellii Thomas, 1902. Both M. levis levis and M. levis dinellii have been recently observed in sympatry in Argentina. This finding suggests that these populations might in fact correspond to distinct species rather than subspecies, as they have traditionally been designated. By using a multivariate morphometric approach, we demonstrate that M. l. levis has secondary sexual dimorphism in several measurements, with females being larger than males; sexual dimorphism was not detected in M. levis dinellii. However, we found morphometric differences between the two taxa. These differences exceeded those documented for other Neotropical Myotis. Based on their sympatry, morphological, and morphometrical differences, we propose a change in the status of both subspecies to M. levis and M. dinellii

Predation on Alouatta guariba clamitans Cabrera (Primates, Atelidae) by Leopardus pardalis (Linnaeus) (Carnivora, Felidae)
There are a few studies about predation on primates. Howler monkeys, being relatively large animals, were believed to be preyed on successfully only by medium to large-sized carnivores and large birds of prey. Our study took place at Chácara Payquerê, which is situated in the municipality of Balsa Nova, State of Paraná, Southern Brazil. Fingers and nails from Alouatta guariba clamitans Cabrera, 1940 were founded in two faecal samples from Leopardus pardalis (Linnaeus, 1758). With our documentation large howler monkey remains in faeces, the possibility of ocelot being a potential predator of all Neotropical primates should be taken into consideration.<br>São poucos os estudos sobre a predação de primatas. Sendo os bugios animais relativamente grandes, acredita-se que somente médios e grandes carnívoros e grandes rapineiros possam lograr sucesso em sua predação. O estudo foi realizado na Chácara Payquerê, situada no município de Balsa Nova, Estado do Paraná, sul do Brasil. Dedos e unhas de Alouatta guariba clamitans Cabrera, 1940 foram encontradas em duas amostras fecais de Leopardus pardalis (Linnaeus, 1758) que foram coletadas. Com este registro de grande primata em fezes, a possibilidade de a jaguatirica ser um potencial predador de todos os primatas neotropicais pode ser levada em consideração
