The family Streblidae consists of obligate hematophagous ectoparasites of bats. The richness of Streblidae may be affected by environmental and host-related variables, collection methods, and sampling effort. The purposes of this study were to list the Streblidae species recorded in Brazil, verify their distribution in the Brazilian biomes and states, and pinpoint the parameters that favored the greatest richness. Through queries in online databases and libraries, 86 publications were found containing records of 83 species in 24 genera. The state with the largest number of publications was São Paulo and Federal District presented the highest richness of Streblidae. The largest number of records of Streblidae species was in Cerrado biome. The meta-analyses utilizing 26 Brazilian inventories showed that the richness of Streblidae was positively correlated with the number of flies and richness and abundance of Phyllostomidae. We hope that the results of this study will contribute to a better understanding of the distribution of research on Streblidae in Brazil and confirming the specificity between Streblidae and Phyllostomidae.

In Mexico, few studies have explored how environmental conditions in tropical dry forests (TDF) influence bat fly load even though, according to climate change scenarios, this ecosystem will experience a drier and warmer climate. Such an extension of the dry season in these ecosystems could have dramatic consequences for biodiversity, particularly in regions with plains where animals do not have elevational climate shifts. The present study therefore evaluates the effect of prevailing environmental conditions during 2015-2019, as well as host body conditions, on the infestation and abundance of bat-specific ectoparasites and the composition and bat fly load in the dry season of a TDF in Yucatan.

Ecological interactions between parasites and their hosts play a fundamental role in evolutionary processes. Selection pressures are exerted on parasites and their hosts, usually resulting in high levels of specificity. Such is the case of ectoparasitic bat-flies, but how large-scale spatial gradients affect the dynamics of their interactions with their bat hosts is still unknown.

Bat flies (Nycteribiidae and Streblidae) have been used to study co-evolutionary patterns between ectoparasites and bats. In the world, Nycteribiidae and Streblidae are represented by approximately 276 and 237 species, respectively. In regions such as the Orinoquia located in the north of South America (Colombia and Venezuela), the richness of bats is high (more than 100 documented species), but studies on Nycteribiidae and Streblidae are scarce and discontinuous.

As part of a widespread ecological study on the ectoparasites of bats in Western Mexico, we report new information on the specificity, and distribution of bat flies in a geographical transition zone between the neartic and neotropical zones. Fifteen (15) species of bats representing three families (Mormoopidae, Phyllostomidae, and Vespertilionidae) were collected in 10 locations throughout western Mexico. A total of 276 bat flies, representing 6 genera and 25 species, were identified four species of the bat flies are new records for the region indicating an expansion of the distribution for (Cockerll, 1910), (Guerrero & Morales-Malacara, 1996), (Peterson & Hürka, 1974) and (Wenzel, 1966).

Background: Understanding the interactions between bat flies and host bats offer us fundamental insights into the coevolutionary and ecological processes in host-parasite relationships. Here, we investigated the identities, host specificity, and patterns of host association of bat flies in a subtropical region in East Asia, which is an understudied region for bat fly research.
Methods: We used both morphological characteristics and DNA barcoding to identify the bat fly species found on 11 cavernicolous bat species from five bat families inhabiting Hong Kong.
