All stages of Amblyomma hadanii n. sp. (Acari: Ixodidae) are described from northwestern Argentina. The diagnostic characters for males are a combination of the pattern of scutal ornamentation, basis capituli dorsally rectangular with cornua, coxa I with two subequal spurs (the internal wider, the external longer), coxae II-III with a single spur, coxa IV with a single spur not reaching level of anus, ventral plates irregular in shape (larger and sometimes with a small incision on festoons 4, 5 and 6) and hypostome spatulate with dental formula 3/3 in 7-8 rows. The diagnostic characters for the females are a combination of scutal ornamentation, postero-lateral margins of scutum slightly convex, coxa I with two subequal spurs (the internal wider, the external longer), basis capituli dorsally rectangular, porose areas rounded, genital aperture U-shaped, and hypostome spatulate with dental formula 3/3 in 7-8 rows. Diagnosis of nymphs can be performed by a combination of basis capituli rectangular, scutum with large punctations in the lateral fields and small punctations in the central field, and cervical groove short and ending as a small shallow depression at the eye level. Larvae are diagnosed by the shape of basis capituli, scutum with with posterior margin slightly convex, and legs with coxa I with 2 triangular spur (the external longer than the internal), and with coxae II and III each with 1 triangular spur. The hosts recorded for this new tick species are Tapirus terrestris (Linnaeus), horse, cattle, dog and humans. Analyses of a 410 bp fragment of the mitochondrial 16S rRNA gene and the complete sequence of the nuclear 18S rRNA gene supported the description of A. hadanii as a new species.
阿根廷西北部描述了哈氏花蜱新种（蜱螨目：硬蜱科）的各个阶段。雄性的诊断特征包括盾板纹饰模式、背甲基部呈矩形且有角、第一对足基节有两个近乎等长的距（内侧的较宽，外侧的较长）、第二至三对足基节各有一个距、第四对足基节有一个距且未达肛门水平、腹板形状不规则（较大，有时在第4、5和6节缘垛处有一个小切口）以及口下板呈铲形，齿式为7 - 8排3/3。雌性的诊断特征包括盾板纹饰、盾板后外侧边缘稍凸、第一对足基节有两个近乎等长的距（内侧的较宽，外侧的较长）、背甲基部呈矩形、多孔区圆形、生殖孔呈U形以及口下板呈铲形，齿式为7 - 8排3/3。若虫的诊断可依据以下特征组合：基节矩形、盾板侧区有大的刻点而中区有小刻点、颈沟短且在眼水平处结束为一个小的浅凹陷。幼虫的诊断依据为基节形状、盾板后缘稍凸、腿部第一对足基节有2个三角形距（外侧的比内侧的长），第二和三对足基节各有1个三角形距。记录的该新蜱种的宿主有南美貘（林奈）、马、牛、狗和人类。对线粒体16S rRNA基因410 bp片段和核18S rRNA基因完整序列的分析支持将哈氏花蜱描述为一个新物种。
