Galagocheles Fain, 1979 (Acari: Cheyletidae), comprising permanent parasites of African prosimian primates (Galagonidae), is revised. An amended diagnosis of the genus based on characters of adults and immatures is given. The type-species, G. lemuricola (Lawrence, 1948), from Otolemur garnetti (Ogilby) (type-host) and O. crassicaudatus Geoffroy, is redescribed, and G. lawrencei n. sp. is described from Galago senegalensis Geoffroy (type-host) and G. moholi Smith. The new species differs from G. lemuricola by its smaller body size, the obtuse posterior end of the opisthosoma in males, and by fine, nude setae ps3 in females. The systematics of the cheyletid tribe Niheliini and host-parasite associations of its species are briefly discussed. The tribe Criokerontini is included to the tribe Niheliini. It is suggested that the ancestors of the tribe Niheliini were predaceous cheyletids associated with the nests of arboreal mammals, and the association of Nihelia spp. on mongooses (Herpestidae) is the result of the host-switching from some ancient arboreal mammal.
加拉戈螯螨属（Galagocheles）由法因于1979年建立（蜱螨亚纲：螯螨科），包含非洲原猴亚目灵长类动物（婴猴科）的永久性寄生虫，现对其进行修订。基于成螨和幼螨的特征给出了该属的修订诊断。对模式种，即来自加纳婴猴（奥吉尔比）（模式宿主）和粗尾婴猴（杰弗里）的狐猴加拉戈螯螨（劳伦斯，1948）进行了重新描述，并描述了来自塞内加尔婴猴（杰弗里）（模式宿主）和莫霍利婴猴（史密斯）的劳伦斯加拉戈螯螨新种。新种与狐猴加拉戈螯螨的区别在于体型较小、雄螨后体后端钝圆以及雌螨有细小的裸毛ps3。简要讨论了螯螨科尼赫利尼族的系统分类及其物种的宿主 - 寄生虫关联。克里奥克罗恩蒂尼族被归入尼赫利尼族。有人认为，尼赫利尼族的祖先为与树栖哺乳动物巢穴相关的捕食性螯螨，而尼赫利亚属在獴（獴科）上的寄生是从某些古代树栖哺乳动物宿主转换的结果。
