The present study reports anomalies in Hyalomma dromedarii and Hyalomma rufipes adults collected from dromedary camels (Camelus dromedarius) in Aswan, Egypt, between January and June 2022. A total of 52 adult ticks displayed one or several local and/or general anomalies. A wide variety of local anomalies was observed including atrophy of one or multiple legs, ectromely, absence of accessory adanal and subanal plates, fusion of adanal and accessory plates, and presence of sclerotized formation in the ventral plate, as well as abnormalities of the spiracle, anal groove, festoon, parma, and posteromedian groove. General anomalies comprised of asymmetries and gynandromorphism. Local anomalies were documented among H. dromedarii and H. rufipes, whereas general anomalies were documented only from H. dromedarii. The present work represents the first report of deuterogynander intrigue gynandromorphism in H. dromedarii, as well as the first report of morphological abnormalities in H. dromedarii and H. rufipes from Egypt.
本研究报告了 2022 年 1 月至 6 月在埃及阿斯旺的单峰驼（Camelus dromedarius）身上采集的成年钝缘蜱（Hyalomma dromedarii）和红缘蜱（Hyalomma rufipes）的异常情况。总共 52 只成年蜱显示出一种或多种局部和/或全身异常。观察到各种各样的局部异常，包括一条或多条腿的萎缩、ectromely、无副肛和亚肛板、肛和副肛板融合，以及腹板上出现硬化形成，以及气门、肛门沟、褶边、parma 和后正中沟的异常。全身异常包括不对称和雌雄同体。局部异常在 H. dromedarii 和 H. rufipes 中均有记录，而全身异常仅在 H. dromedarii 中记录。本研究报告了 H. dromedarii 中首次发现的第二性征雌雄同体性反转雌雄同体现象，以及 H. dromedarii 和 H. rufipes 在埃及首次报道的形态异常。
