Paralysis of Angora goat kids caused by adult ticks, which most probably belong to an undescribed species of the Rhipicephalus pravus group, is described. Confirmed cases of paralysis occurred in the south-western Orange Free State between the second half of September and the first half of November as well as during the first half of February. The mean female tick burdens (mean = 21.4) of paralysed Angora kids were significantly higher than those of healthy kids (mean = 4.4). The predilection attachment site of the adult ticks was the ears of the goats. The elephant shrew Elephantulus myurus is a preferred host of the immature stages whereas the scrub hare Lepus saxatilis serves as an important host for the adult ticks.
描述了由成年蜱引起的安哥拉山羊幼崽麻痹症，这些蜱很可能属于尚未描述的草原硬蜱（Rhipicephalus pravus）类群的一个物种。确诊的麻痹症病例发生在奥兰治自由邦西南部，时间为9月下半月至11月上半月以及2月上半月。麻痹的安哥拉山羊幼崽身上雌蜱的平均数量（平均 = 21.4）显著高于健康幼崽（平均 = 4.4）。成年蜱的偏好附着部位是山羊的耳朵。象鼩（Elephantulus myurus）是未成熟阶段蜱的首选宿主，而灌丛兔（Lepus saxatilis）是成年蜱的重要宿主。
