In this work we record the highest number of bat flies species among those already performed in the Brazilian cerrado and discuss the associations and patterns of parasitism of these species and their hosts. A total of 1,390 ectoparasitic flies were collected, belonging to 24 species of Streblidae and one of Nycteribiidae, parasitizing 227 bats of 15 species. Among the species found, the presence of Trichobius sp. on Lonchophylla mordax and the first occurrence of Hershkovitzia sp. on Thyroptera devivoi are highlighted. Lophostoma species presented the highest proportion of individuals with infracommunities and the highest values of parasitological indexes. The high number of bat fly species and hosts, as well as the high values for rates of parasitism and infracommunities, suggests that this area of cerrado has good shelter conditions for these species. The abundance of species and high rates of parasitism detracts from the hypothesis that a higher mean intensity of ectoparasites results from lower competition among flies for hosts in areas with lower ectoparasite species richness. Biogeographical and historical factors of host populations, besides the number of host species and individuals sampled, may contribute to species number and intensity of parasitism.

A total of 71 bat flies belonging to families Nycteribiidae and Streblidae, and 37 mites were collected on 12 species of bats (Phyllostomidae and Vespertilionidae) from the Chapada do Abanador (Minas Gerais, Brazil), between July 2009 and April 2010. Two new occurrences of ectoparasites were recorded on Histiotus velatus (bat fly Basilia producta) and on Carollia perspicillata (mite Parichoronyssus bakeri). Five new occurrences were recorded for the state of Minas Gerais, increasing the range for bat flies Anatrichobius passosi, Paraeuctenodes similis, Basilia juquiensis, Basilia producta and for mite Periglischrus vargasi. Moreover, two new species of mites were recorded for Brazil (P. bakeri and Macronyssus aff. leislerianus). With regard to infracommunities, the most frequent association was between Anastrebla modestini and Exastinion clovisi on bat Anoura geoffroyi. This study contributed to characterize the fauna of bat ectoparasites in representative but poorly-sampled environments of the Atlantic Forest, the campos de altitude (high altitude grasslands) and cloud forests of southern Minas Gerais.

Two species and one subspecies are described as new: Trichobius machadoallisoni sp. n., from Pteronotus personatus, is a member of caecus group, and closely related to T. bilobus Wenzel, 1976; however, T. machadoallisoni has the syntergite 1+2 lightly convex and with more than 21 setae. Trichobius anducei sp. n., from Carollia perspicillata, a member of parasiticus complex, differs from all other species in having a strip of long lateral connexival setae, in the number and position of setae in tergite 7 and epiproct in females, in the shape of gonopods, the number of setae in syntergosternite 7+8 and tergite 9 in males. Trichobius dugesioides phyllostomus subsp. n., from Phyllostomus elongatus differs from T. d. dugesioides Wenzel, 1966 in having more denticles in male gonopods and longer posterior setae in the tergite 7 of females. Trichobius d. dugesioides is redescribed, showing sexual dimorphism in distribution of microtrichia in the presutural area of scutum. Some morphotypes of Trichobius joblingi Wenzel, 1966 are compared with Trichobius persimilis Wenzel, 1976, reducing geographical distribution of the latter to the North of Orinoco river.

The genus Xenotrichobius Wenzel, 1976 is revised using specimens collected in Venezuela and Peru. X. noctilionis Wenzel, 1976 is redescribed including the puparium. The new species, X. linaresi sp. n., differs from type species in size and shape of male genitalia, and longer setae on dorso-lateral connexivum. Xenotrichobius sp., a single female, has 1 pair of macrosetae in the epiproct and Xenotrichobius sp., a single male, characterized by longitudinal median and transverse mesonotal sutures joined, are described. Close relationships among Xenotrichobius, Paradyschiria Speiser, 1900 and Noctiliostrebla Wenzel, 1966 is supposed, due to the structure of male genitalia, the development of proctiger, and the shape of puparium. A key for the species is given.
