We present information on Nycteribiidae flies parasitizing the bat families Pteropodidae, Miniopteridae and Vespertilionidae from the Malagasy Region, contributing insight into their diversity and host preference.
Our phylogenetic analysis identified nine clusters of nycteribiid bat flies on Madagascar and the neighbouring Comoros Archipelago. Bat flies sampled from frugivorous bats of the family Pteropodidae are monoxenous: Eucampsipoda madagascariensis, E. theodori and Cyclopodia dubia appear wholly restricted to Rousettus madagascariensis, R. obliviosus and Eidolon dupreanum, respectively. Two different host preference patterns occurred in nycteribiids infecting insectivorous bats. Flies parasitizing bats of the genera Miniopterus (Miniopteridae) and Myotis (Vespertilionidae), namely Penicillidia leptothrinax, Penicillidia sp. and Nycteribia stylidiopsis, are polyxenous and showed little host preference, while those parasitizing the genera Pipistrellus and Scotophilus (both Vespertilionidae) and referable to Basilia spp., are monoxenous. Lastly, the inferred Bayesian phylogeny revealed that the genus Basilia, as currently configured, is paraphyletic.
This study provides new information on the differentiation of nycteribiid taxa, including undescribed species. Host preference is either strict as exemplified by flies parasitizing fruit bats, or more relaxed as found on some insectivorous bat species, possibly because of roost site sharing. Detailed taxonomic work is needed to address three undescribed nycteribiid taxa found on Pipistrellus and Scotophilus, tentatively allocated to the genus Basilia, but possibly warranting different generic allocation.
我们介绍了马达加斯加地区翼手目蝙蝠科、蝙蝠科和蝙蝠科寄生蝇科的信息，为了解其多样性和宿主偏好提供了依据。
我们的系统发育分析确定了在马达加斯加和邻近的科摩罗群岛的 9 个翼手目蝙蝠蝇群。从翼手目蝙蝠科的果蝠中采集的蝙蝠蝇是单宿主的：Eucampsipoda madagascariensis、E. theodori 和 Cyclopodia dubia 似乎完全局限于 Rousettus madagascariensis、R. obliviosus 和 Eidolon dupreanum。感染食虫蝙蝠的翼手目寄生蝇有两种不同的宿主偏好模式。寄生在 Miniopterus（蝙蝠科）和 Myotis（蝙蝠科）属蝙蝠的蝇类，即 Penicillidia leptothrinax、Penicillidia sp. 和 Nycteribia stylidiopsis，是多宿主的，没有明显的宿主偏好，而寄生在 Pipistrellus 和 Scotophilus（均为蝙蝠科）属的蝇类，即 Basilia spp.，是单宿主的。最后，推断的贝叶斯系统发育表明，目前配置的 Basilia 属是并系的。
本研究提供了关于翼手目寄生蝇类分类分化的新信息，包括未描述的物种。宿主偏好要么像寄生果蝠的蝇类那样严格，要么像一些食虫蝙蝠物种那样更宽松，这可能是因为栖息地共享。需要进行详细的分类学工作来解决在 Pipistrellus 和 Scotophilus 上发现的三种未描述的翼手目寄生蝇类，这些蝇类暂定为 Basilia 属，但可能需要不同的属分配。
