Haemaphysalis qinghaiensis Teng (Acta Zootaxon Sin 5:144-149, 1980) is an endemic species in China. This tick species was first described based on engorged or semi-engorged specimens, and the drawings and description in words of morphological characteristics were poor. Therefore, the present study aims to redescribe morphological characteristics of all active stages of this tick species in detail by scanning electron microscopy. Additionally, a comparison between H. qinghaiensis and other sympatric Haemaphysalis species was also analyzed. Males of H. qinghaiensis can be distinguished from sympatric Haemaphysalis species by the following characters: palpi less salient laterally and curved in contour; ventrointernal setae of palpal segment II thin, number <7; the tips of palpal segment III not so strongly recurved inward to become "pincerlike" and lacking dorsal spur; dental formula 5/5; lateral grooves enclose first festoon; coxa IV with a short, broadly triangular spur; tarsi somewhat humped; and spiracular plates long comma-shaped. Females of H. qinghaiensis can be distinguished by palpi less salient laterally and curved in contour; ventrointernal setae of palpal segment II thin, number <7; segment III of palpi lacking dorsal spur; dental formula 4/4; scutum subcircula; and tarsi somewhat humped. Nymphs of H. qinghaiensis can be distinguished from those of other species by palpi less salient laterally and curved in contour; dental formula 2/2; basis capituli rectangular, with distinct dorsal cornua, without ventral cornua; and spiracular plates with short and narrow dorsal prolongation. Larvae of H. qinghaiensis can be distinguished by palpi less salient laterally and curved in contour; basis capituli rectangular, without distinct cornua.
青海血蜱（Teng，《动物分类学报》5:144 - 149，1980年）是中国的特有物种。该蜱种最初是根据饱血或半饱血标本描述的，其形态特征的绘图和文字描述都很不完善。因此，本研究旨在通过扫描电子显微镜详细重新描述该蜱种各活动阶段的形态特征。此外，还分析了青海血蜱与其他同域分布的血蜱属物种之间的差异。青海血蜱雄蜱可通过以下特征与同域分布的血蜱属物种区分开来：须肢侧面不太突出且轮廓弯曲；须肢第二节腹内侧刚毛细，数量<7根；须肢第三节末端向内弯曲不强烈，不成“钳状”且无背距；齿式5/5；侧沟包围第一缘垛；第四对足基节有一个短而宽的三角形距；跗节稍隆起；气门板长逗号形。青海血蜱雌蜱可通过以下特征区分：须肢侧面不太突出且轮廓弯曲；须肢第二节腹内侧刚毛细，数量<7根；须肢第三节无背距；齿式4/4；盾板近圆形；跗节稍隆起。青海血蜱若蜱可通过以下特征与其他物种的若蜱区分开来：须肢侧面不太突出且轮廓弯曲；齿式2/2；假头基部矩形，有明显的背角，无腹角；气门板有短而窄的背延长部分。青海血蜱幼虫可通过以下特征区分：须肢侧面不太突出且轮廓弯曲；假头基部矩形，无明显角。
