Ixodes brevisetosus n. sp. from Papua New Guinea, Ixodes contrarius n. sp. from Costa Rica, Ixodes guglielmonei n. sp. from Argentina and Chile, Ixodes insulae n. sp. from Australia, Ixodes moralesi n. sp. from Guatemala and Panama, Ixodes rio n. sp. from Brazil, Ixodes robbinsi n. sp. from Canada and the United States and Ixodes tinamou n. sp. from Peru (Acari: Ixodidae) are described based on females, nymphs and larvae from various avian hosts (Charadriiformes: Charadriidae; Falconiformes: Falconidae; Galliformes: Cracidae, Odontophoridae, Phasianidae; Passeriformes: Acanthizidae, Cardinalidae, Emberizidae, Fringillidae, Furnariidae, Melanocharitidae, Orthonychidae, Paridae, Passeridae, Petroicidae, Thamnophilidae, Troglodytidae, Turdidae; Strigiformes: Strigidae; Tinamiformes: Tinamidae) and a rodent (Rodentia: Muridae). Females, nymphs and larvae of all new species are similar to those of Ixodes auritulus Neumann, 1904, but can be distinguished by the shape of the scutum and basis capituli, relative length of idiosomal setae, auriculae and internal projection on palpal segment I, degree of development of dorsoapical and mesodorsal spurs on palpal segment I, and measurements and proportions of various structures. Females, nymphs and larvae of I. auritulus s. str. are redescribed based on specimens from passerine birds (Furnariidae, Troglodytidae, Turdidae) in Chile. The subspecies I. auritulus zealandicus Dumbleton, 1961 is elevated to species status, Ixodes zealandicus Dumbleton, 1961. Based on our extensive survey and morphological analyses, we evaluate the actual species richness in the I. auritulus species group and discuss future directions in the systematics of this group of ticks.
新几内亚的短角血蜱、哥斯达黎加的相反血蜱、阿根廷和智利的古氏血蜱、澳大利亚的岛屿血蜱、危地马拉和巴拿马的莫拉莱斯血蜱、巴西的里奥血蜱、加拿大和美国的罗宾斯血蜱以及秘鲁的塔那鸟血蜱（蜱螨目：血蜱科）是根据来自各种鸟类宿主（鸻形目：鸻科；隼形目：隼科；鸡形目：雉科、齿鹑科、凤冠雉科；雀形目：刺嘴莺科、唐纳雀科、灶鸟科、雉科、雀科、蚋科、霸鹟科、梅花雀科、寡妇鸟科、山雀科、鹟科、灶鸟科、吸蜜鸟科、翠鸟科、琴鸟科）和一种啮齿动物（啮齿目：鼠科）的雌性、若虫和幼虫描述的。所有新种的雌性、若虫和幼虫都与 1904 年由诺依曼命名的奥蒂图斯血蜱相似，但可以通过盾板和头胸部基础的形状、体节上刚毛、耳状突和第一跗节内突的相对长度、第一跗节背侧和背中线刺的发育程度以及各种结构的测量和比例来区分。基于智利雀形目鸟类（灶鸟科、吸蜜鸟科、翠鸟科、唐纳雀科、山雀科、鹟科、琴鸟科）的标本，重新描述了奥蒂图斯血蜱的雌性、若虫和幼虫。亚种奥蒂图斯血蜱新西兰亚种降为种级地位，即新西兰血蜱。基于我们广泛的调查和形态学分析，我们评估了奥蒂图斯血蜱种组的实际物种丰富度，并讨论了该蜱种组系统学的未来方向。
