根据在蜥蜴和狐狸身上采集的标本，描述了伊蠓的所有寄生阶段。这一新物种取代了西班牙、葡萄牙、摩洛哥、阿尔及利亚和突尼斯等地中海地区干旱地区的蓖麻蠓。它也在德国西部与蓖麻I. ricinus同属的地区被收集到，远离其已知的分布范围，并且在一个不寻常的宿主上。该新种的雌虫可通过其鳞片的相对尺寸和点状、独特体刚毛的长度、耳廓的大小和孔区的形状来与蓖麻属的雌虫区分开来。根据果皮尺寸、果皮和异果皮刚毛的相对大小以及尾椎上刺的相对大小，可以很容易地与蓖麻虫区分开来。新种幼虫的果皮较宽，且特有体的Md1 ~ Md3刚毛较长。该新种与西班牙和葡萄牙的蓖麻属属异域分布。据推测，至少在北非、西班牙南部和葡萄牙西南部的部分地区，它在历史上被忽视，并被报道为蓖麻属。蓖麻虫复合体中新物种的存在使得有必要对其完整分布、非生物偏好和季节性活动以及其宿主和对病原体传播的影响进行批判性评估。(C) 2014 Elsevier GmbH版权所有。
All of the parasitic stages of Ixodes inopinatus n. sp. are described from specimens collected by flagging and on lizards and foxes. The new species replaces I. ricinus in dry areas of the Mediterranean region in Spain, Portugal, Morocco, Algeria and Tunisia. It has also been collected in areas of western Germany in sympatry with I. ricinus, far of its known distribution range and on an unusual host. The females of the new species can be separated from I. ricinus by the relative dimensions and punctations of the scutum, the length of the idiosomal setae, the size of the auriculae, and the aspect of the porose areas. Nymphs of L inopinatus can be easily separated from I. ricinus by a combination of scutal dimensions, the relative size of scutal and alloscutal setae, and the relative size of the spurs on coxa I. The larvae of the new species have a broader than long scutum and unusually long Md1 to Md3 idiosomal setae. The new species is allopatric with I. ricinus in Spain and Portugal. It is hypothesized that it has been historically overlooked and reported as I. ricinus at least in northern Africa, southern Spain and parts of south-western Portugal. The existence of a new species in the I. ricinus complex makes necessary the critical assessment of its complete distribution, its abiotic preferences and seasonal activity, as well as its hosts and implications for the transmission of pathogens.
