摘要
用扫描电镜对越南血蜱（Ｈａｅｍａｐｈｙｓａｌｉｓｖｉｅｔｎａｍｅｎｓｉｓ）的成虫、若虫和幼虫进行了形态学观察。成虫、若虫、幼虫的哈氏器囊孔形似“逗点状”，与本属其他种的不同。若虫背部有１对环形感器（ｓｅｎｓｉｌｕｍｓａｇｉｔｔｉｆｏｒｍｅ），侧部有２对环形感器；足Ⅰ、Ⅱ、Ⅳ基节内外侧各有１个环形感器，足Ⅲ基节外侧有２个、内侧有１个环形感器。幼虫须肢第Ⅳ节基部偏向腹侧有１根粗而弯曲的感毛；虫体背面和侧面各有１对环形感器，腹面足各基节内外侧各有１个环形感器。
Detailed morphological studies of adults, nymphs and larvae of H.vietnamensis were carried out first under SEM by the authors. The capsule pore of Haller′s organ of all developmental stages of H.vietnamensis is comma shape, and differs from all the other species of Haemaphysalis in which it is a transverse slit.Morphological characters of nymph of H.vietnamensis were observed under scanning electron microscope. It was found that there are one pair of sensillum sagittiform on the dorsum and two pairs on lateral sides. There are one sensillum sagittiform in both inside and outside of coxa Ⅰ,Ⅱ,Ⅳ, and another two in lateral side and one in internal side of coxa Ⅲ. These features of site and number of the sensillum sagttiform are different from those described in other reports.There is a thick curved seta on the ventral basal part of segment Ⅳ of palp. It was found that there are one pair of sensillum sagittiform on the dorsum and another pair on the lateral position near the festorn. There is one sensillum sagittiform in both inside and outside of coxae.
