In total, 57 ticks were collected from six white-tailed deer (Odocoileus virginianus) and three mule deer (O. hemionus) in northern Mexico during the 2017, 2018 and 2019 hunting seasons. Morphological features of adult male and female ticks were observed and photographed using a stereo-microscope and scanning electron micrography. The ticks were identified as Dermacentor albipictus based on taxonomic keys. Molecular analysis using DNA amplification of the 16S rDNA and cytochrome oxidase 1 (COI) genes was employed to resolve the phylogenetic relationships from 18 strains of Dermacentor species. Bayesian phylogenetic analysis was performed in order to obtain a phylogenetic tree based on the concatenated sequence in the D. albipictus clade. The geometric morphometric analysis compared the body shape of ticks collected from specimens of two deer species by analyzing nine dorsal and ventral landmarks from both males and females. The results suggest that body shape variation in dorsal structures might be related to the host.

在2017 年、2018 年和 2019 年的狩猎季节，从墨西哥北部的6 只白尾鹿 ( Odocoileus virginianus ) 和三只骡鹿 ( O. hemionus ) 中总共收集了 57 只蜱。使用立体显微镜和扫描电子显微术观察并拍摄成年雄性和雌性蜱的形态特征。基于分类学关键字，蜱被鉴定为白纹皮蜱。使用 16S rDNA 和细胞色素氧化酶 1 (COI) 基因的 DNA 扩增的分子分析被用来解决来自 18 株Dermacentor物种的系统发育关系。进行贝叶斯系统发育分析以获得基于连接序列的系统发育树D. albipictus进化枝。几何形态测量分析通过分析雄性和雌性的 9 个背侧和腹侧标志，比较了从两种鹿的标本中收集的蜱的体形。结果表明，背部结构的体型变化可能与宿主有关。
