雌雄同形现象是指在一个正常的两性异形物种的单个个体中同时发生雄性和雌性的基因型和形态特征，在蜱中是罕见的。这种现象以前在代表几个蜱属的自由生活标本中有记录，特别是Amblyomma和Hyalomma，但在硬蜱中很少。在这里，我们描述了前两个已知的gynandromorphs的黑腿蜱，肩突硬蜱说，收集，而在日常蜱监测期间，在哈德逊谷地区的纽约州的植被标记。独特的是，这两个标本显示出一些典型的形态特征，除了男性和女性。
Gynandromorphism, the simultaneous occurrence of both male and female genotypic and morphological characteristics in a single individual of a normally sexually dimorphic species, is rare in ticks. The phenomenon is documented previously for free-living specimens representing several tick genera, particularly Amblyomma and Hyalomma, but only rarely in Ixodes. Here we describe the first two known gynandromorphs of the blacklegged tick, Ixodes scapularis Say, collected while flagging vegetation during routine tick surveillance in the Hudson Valley region of New York State. Uniquely, both specimens display some morphological features typical of nymphs, in addition to those of both males and females.
