It has been proved on Mallophaga that the notion "hostal subspecies" can be applied at the level of intraspecies categories to constant parasites possessing, distinct specificity. The notion should be applied in those cases when there are but small differences between groups of parasites from different hosts (e. g. in sizes) and when hosts belong to different species of the same genus.
在食毛目昆虫方面已经证实，“宿主亚种”这一概念可在种内分类层面应用于具有明显特异性的固定寄生虫。当来自不同宿主的寄生虫群体之间差异很小（例如在大小方面）且宿主属于同一属的不同物种时，就应应用这一概念。
