New records for chewing lice of the genus Dennyus Neumann, 1906 (Phthiraptera: Amblycera) on two swifts from Saudi Arabia

Very little information was known for the chewing lice fauna of Saudi Arabia especially from hosts of Apodiformes. Swifts (Apodiformes) are common resident and migratory passerine birds through Saudi Arabia. Through the world there are two chewing lice genera that are known to infest swifts: Dennyus Neumann, 1906 and Eureum Nitzsch, 1818. None of them were recorded from the kingdom before.Two species of resident wild swifts were examined for chewing lice for the first time in Saudi Arabia. Two rare lice species were identified: Dennyus (Dennyus) cypsiurus Thompson, 1948 and D. (Dennyus) hirundinis (Linnaeus, 1761) (Phthiraptera: Amblycera: Menoponidae) infesting African palm swift Cypsiurus parvus (Lichtenstein, 1823) and common swift Apus apus (Linnaeus, 1758), respectively. The described species are considered as new country records. They will be added to the Saudi Arabia parasitic fauna. Taxonomical and ecological remarks were provided for the identified chewing lice through this work, along with notes on swift/chewing lice interaction.

关于沙特阿拉伯咀嚼虱类群落的资料极为匮乏，尤其是在Apodiformes宿主方面。在沙特阿拉伯，隼科鸟类（Apodiformes）作为常见的留鸟和候鸟广泛分布。全球范围内，已知有两种咀嚼虱属类群寄生隼类：Dennyus Neumann, 1906和Eureum Nitzsch, 1818。然而，这些种类在此之前均未被记录于该国境内。本研究首次对沙特阿拉伯两种留鸟野生隼进行了咀嚼虱的调查。鉴定出两种罕见的虱类物种：Dennyus (Dennyus) cypsiurus Thompson, 1948和D. (Dennyus) hirundinis (Linnaeus, 1761)（Phthiraptera: Amblycera: Menoponidae），分别寄生在非洲棕榈隼Cypsiurus parvus (Lichtenstein, 1823)和普通隼Apus apus (Linnaeus, 1758)身上。所描述的物种均被视为该国的新记录，并将被纳入沙特阿拉伯的寄生动物群落中。本研究提供了所鉴定咀嚼虱的分类学和生态学评论，以及关于隼与咀嚼虱相互作用的笔记。
