Remarks. This species-group is characterized by the presence of one or two apophyses on palpal tibia, a variable tegular apophysis, and a small U-shaped embolus arising from the tegulum at the central to sub-central position ( Jäger 2020). The two newly described species, Olios biprocessus Hu, Zhang & Liu , sp. nov. and O. uniprocessus Hu, Zhang & Liu , sp. nov., exhibit all the diagnostic characteristics of this species-group. Therefore, they clearly belong to this species-group.
