Remarks

• Systematics: Among the five known species of the genus, Chionandaspis glutae is the most derivative in having fused median trullae in the adult and second-instar females, which are highly adapted to burrowing. (Takagi, 2008a) This species is very similar to the other two leaf-associated species, C. foliicola and C. Palawanensis, but differs from them in the following characters (C. foliicola and C. palawanensis in brackets): Pygidium with lateral margins straight [concave subapically]; median trullae fused together apically [set close together, but not fused], notched once on lateral margin [minutely serrate]; sclerosis occurring between bases of median trullae oblong [shaped like an inverted U]; both abd III and IV with submedian and submarginal series of dorsal macroducts [abd IV without submedian dorsal macroducts]; lateral macroducts occurring only on abd I and II [occurring also on meso- and metathorax]; no gland spines on thorax [with gland spines on meso and metathorax]. Furthermore it differs from C. foliicola in having the anus situated at the center of the pygidium [in C. foliicola", the anus is situated much posteriorly to the level of the vulva]. (Takagi, 2008a)
• Biology: Females occurring on the lower surface of the leaf, burrowing into the leaf blade just beside the midrib or other veins. The burrow is visible through a tranparent upper epidermal layer of the leaf, showing a white patch within, which should be secreted wax or the test. (Takagi, 2008a)
