Abstract：
Mites of the family Syringophilidae (Acariformes: Prostigmata: Cheyletoidea) are permanent and obligatory parasites of birds. This study presents an analysis of mite material collected from 22 avian species belonging to the family Paradisaeidae (Passeriformes), revealing the presence of four mite species belonging to four genera: Syringophiloidus attenboroughi n. sp., Peristerophila regiusi n. comb., Picobia frankei, and Gunabopicobia garylarsoni. In the present work, the genus Neoperisterophila is synonymized with the genus Peristerophila. While the genera Syringophiloidus and Picobia were expectedly found on paradisaeid birds, given their prevalence in passerines, the presence of Peristerophila and Gunabopicobia was intriguing, suggesting potential host-switching events. The specificity of these mites varies, with some showing occurrence on hosts of closely related genera and others infesting phylogenetically distant hosts. Notably, the distribution of specific mite species on the Birds-of-Paradise appears to be influenced by both long coevolutionary histories and incidental contacts between often unrelated or intergeneric hybrid species of paradisaeid birds. Furthermore, our research of 104 specimens from 22 Birds-of-Paradise species shows generally low infestation rates across the studied species, suggesting a nuanced interaction between these mites and their avian hosts. Additionally, our network analysis provides a deeper understanding of these host-parasite interactions, revealing a high level of specialization and complexity in these ecological relationships.
摘要：
嗜Syringilidae家族的螨（A虫：Prostigmata：Cheyletoidea）是鸟类的永久性和强制性寄生虫。这项研究分析了从属于Paradisaeidae（Passeriformes）的22种鸟类中收集的螨材料，揭示了属于四个属的四个螨物种的存在：Syringophiloidusattenboroughin.sp.,Peristerophilaregiusin.comb.,Picobiafrankei,还有GunabopicobiaGarylarsoni.在目前的工作中,新风菌属与Peristerophila属同义。虽然预期在paradisaid鸟类上发现了Syringophiodus和Picobia属，鉴于它们在雀形目中的流行，Peristerophila和Gunabopicobia的存在很有趣，提示潜在的主机切换事件。这些螨虫的特异性各不相同，其中一些显示在密切相关属的宿主上发生，另一些显示在系统发育远亲宿主上。值得注意的是,天堂鸟上特定螨物种的分布似乎受到长期的共同进化历史以及通常不相关或属间杂种之间的偶然接触的影响。此外，我们对来自22个天堂鸟物种的104个标本的研究表明，在所研究的物种中，侵染率普遍较低，表明这些螨虫和它们的禽类宿主之间有微妙的相互作用。此外,我们的网络分析提供了对这些宿主-寄生虫相互作用的更深入的理解，揭示了这些生态关系的高度专业化和复杂性。
