Bats provide essential ecosystem services and some are cave dependent. Caves favour the association of bats with ectoparasite Diptera, however, they are poorly sampled in the Amazon biome. Here we present the first description of a community of bats and bat flies from the largest sandstone cave in Brazil, the Planaltina cave, located in the municipality of Brasil Novo, state of Pará. Diptera were removed from captured bats and taken to the laboratory for identification. From nine species of bats belonging to four families we recorded 17 species of Diptera, 13 were monoxenous. A possible explanation for the monoxenous parasites collected is that flies have poor survival in unusual hosts. These results are an indicator that the Streblid species are host-specific since even if the hosts take refuge in the same cave, they will not share their parasites. Therefore, the present study provides important information on the parasite-host dynamics in a cave, thus highlighting the importance of cave as are essential shelters for bat species and, despite reported cases of cohabitation, mixed colonies are unlikely to form.

First multi-instar descriptions of cave-dwelling Whartonia Ewing, 1944 (Parasitengona, Leeuwenhoekiidae) from Brazil through integrative taxonomy

For the first time deutonymphs and adults (females and males) of species belonging to Whartonia, a genus with post-larval stages commonly found in caves and larvae as ectoparasites of bats, are described. Two species from new localities in states of Pará (Eastern Amazon) and Minas Gerais (southeastern Brazil) are reported. Post-larval cave dwelling mites could be unambiguously associated with W. (W). pachywhartoni and W. (W.) nudosetosa larvae using mitochondrial COI and nuclear ribosomal 28S sequence data, despite apparent oversplitting by species delimitation methods. They are distinguished from closely related Albeckia senase, a species with described deutonymphs, by having eyes and by the shape of idiosomal setae. They are very similar to each other, being distinguished mainly by the distribution of special setae on legs, and shape of idiosomal setae. Detailed redescriptions of the two larvae are presented based on individuals found on bats belonging to nine species, with six new host species association: Anoura caudifer, Diphylla ecaudata, Mimon bennettii, Platyrrhinus lineatus, Sturnira lilium (Phyllostomidae) and Peropteryx trinitatis (Emballonuridae).
