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.
6 species of the five families were found in the Świętokrzyski Region; they included one species of the family Gasterophilidae. two species of the family Hypodermatidae. one species of the family Oestridae, one species of the family Hippoboscidae and one of the family Nycteribiidae. which account for 25%, 50%, 17%. 9% and 10% respectively, of their numbers recorded from Poland. Most of them are widely distributed and some of them are specific ectoparasites of numerous birds and mammals. Larvae of the others are specific endoparasites of several mammalian species. One of the species in this group is new to the region studied.
