In a recent study, we relegated the taxon Ixodes aragaoi Fonseca, 1935 to a junior synonym of Ixodes fuscipes Koch, 1844, and reinstated Ixodes spinosus Neumann, 1899 (a former synonym of I. fuscipes) to a valid species. We examined all lots of ticks formerly identified as I. fuscipes or I. aragaoi in three tick collections of Brazil. Through morphological analysis, some of the examined specimens could not be assigned to either I. fuscipes or I. spinosus based on the examination of the type specimens of these two species. Herein, we report these ticks to represent three different species: Ixodes catarinensis n. sp. Onofrio & Labruna, Ixodes lasallei Méndez Arocha and Ortiz, 1958, and Ixodes bocatorensis Apanaskevich and Bermúdez, 2017. The latter two species are reported for the first time in Brazil. Phylogenetic analysis inferred from the tick 16S rRNA gene partial sequences corroborated our morphological analysis, indicating that I. spinosus, I. lasallei, I. bocatorensis, and I. catarinensis n. sp. form a natural group of neotropical ticks. With the present study, the number of Ixodes species in Brazil increases from 9 to 12. We propose a new identification key for females and males of Ixodes species currently recognized in Brazil.

说明了巴西新虫科(Acari:Ixodidae)以及拉索虫(Ixodes lasallei)和博克托虫(Ixodes bocatorensis)的首次报道。

在最近的研究中,我们退居类群硬蜱aragaoi丰塞卡,1935年同物异名的硬蜱蝽科赫,1844年,并恢复硬蜱刺诺伊曼1899年(曾任代名词I.蝽)为有效的物种。我们检查了巴西三个tick子集合中以前被标识为I. fuscipesI. aragaoi的所有lots子。通过形态分析,根据对这两个物种的类型标本的检查,某些被检标本无法归类为脓疱棘突。在这里,我们报告这些壁虱代表三种不同的物种:氧化卡德克斯犬。sp。Onofrio&LabrunaIxodes lasalleiMéndezArocha和Ortiz,1958年以及Ixodes bocatorensis Apanaskevich和Bermúdez,2017年。后两个物种在巴西首次报道。从蜱16S rRNA基因的部分序列推断系统发生分析证实了我们的形态分析,表明一刺,I. lasallei,I. bocatorensis,I. catarinensis ñ。sp。形成一组自然的新热带tick。通过本研究,巴西的鳞动物种类从9种增加到12种。我们为目前在巴西公认的鳞动物的雌性和雄性提出了新的识别密钥。
