Study of the apron in 9 species of the genus Dermacentor from the fauna of the USSR has revealed differencies in its structure. The subgenus Dermacentor (s. str.) differs from two other subgenera both in the shape of the apron itself and in the shape of the postgenital sclerite and setae of perigenital area. Close species within each of two other subgenera differ in apron proportion, shape and size of denticles along its hind edge, and sometimes in their number. Inspite of the statistically reliable interspecific differences in apron structure a wide range of individual variability of some details and geographical specificity of samples from various places of the area were observed in species with a vast area.
对苏联动物区系中9种革蜱属蜱类盾板的研究揭示了其结构上的差异。革蜱亚属（狭义）在盾板本身的形状以及生殖后骨片和围生殖区刚毛的形状上与其他两个亚属均有所不同。其他两个亚属中各自的近缘种在盾板比例、后缘齿突的形状和大小上存在差异，有时在数量上也有差异。尽管盾板结构存在统计学上可靠的种间差异，但在分布区域广阔的物种中，观察到某些细节存在广泛的个体变异性以及来自该地区不同地点样本的地理特异性。
