• Systematics: Unachionaspis multiglandularis. is similar to U. signata in body shape and pygidial margin, but can be distinguished by the following characteristics of the adult female (character states of U. signata in brackets): (i) submarginal gland spines only present on abd. I–IV, absent from mesothorax and metathorax (submarginal gland spines present on mesothorax and metathorax); (ii) dorsal macroducts numbering about 150 on each side (about 80 on each side); (iii) posterior spiracles not associated with disc pores (posterior spiracles each associated with a few pores); (iv) perivulvar pores numbering more than 65 on each side (about 30 on each side). (Tian & Xing, 2022a)

Exposed body of adult female yellow, asymmetric; anterior end narrow; body gradually expanding posteriorly, widest at abd. I, with a wide, pocket-shaped lateral expansion; distal half tapering posteriorly, pygidium rounded. Scale cover of immature male white, elongate, 1.2– 1.5 mm long, about 0.5 mm wide, without longitudinal ridges, slightly dilated on each side, not parallel sided.
