The present report describes morphological anomalies in Rhipicephalus sanguineus s.s. collected from dogs between February 2017 and May 2019 in the steppic region of Djelfa and high plateau area of Bordj-Bou-Arreridj in Algeria. Out of 1043 ticks from 147 infested dogs, four adult ticks (0.38%), collected from four dogs, exhibited local morphological abnormalities. One male displayed ectromely of leg I left, and the other three specimens exhibited multiple associated anomalies in idiosomas and exoskeletons, festoons, stigmas (spiracles), as well as in adanal and accessory plates. This report provides additional exemplars of morphological abnormalities in tick populations of Africa, particularly North Africa.

本报告描述了2017年2月至2019年5月之间在Djelfa草原地区和阿尔及利亚Bordj-Bou-Arreridj高高原地区从狗身上收集的Rhipicephalus sanguineus s的形态异常。在147只受感染的狗的1043只tick中，从四只狗收集的四个成年tick（0.38％）表现出局部形态异常。一只雄性显示出我的左腿的直肠，而其他三个标本则在成骨瘤和外骨骼，胎儿，柱头（气门），以及肛门和附件板中表现出多个相关的异常。该报告提供了非洲，特别是北非的壁虱种群形态异常的其他示例。
