Remarks

• Systematics: The species is closely similar to Himalaspis caroli (=Chionaspis caroli Green). H. clerodendri may be recognizable most easily in having a number of macroducts on the meso- and metathorax whereas H. caroli has macroducts on the thorax only occasionally. Another conspicuous character of H. clerodendri is the occurrence of dense spicules on the median ventral surface of the meso- and metathorax and the base of the abdomen, whereas Green's description has no mention of such spicules. In H. clerodendri the anus overlaps with the median perivulvar disc pores, whereas in H. caroli it is situated a little anteriorly to the level of these disc pores. The female tests of H. clerodendri occur irregularly on the leaf blade, whereas those of H. caroli are disposed on the recurved edge of the leaf. (Takagi, 2007a)
• Structure: Adult female body fusiform with free abdominal segments moderately lobed laterally; when full grown with pygidial margin set back on ventral surface, median and second trullae scarcely projecting and orifices of marginal macroducts distorted. Medial trullae notched once or twice on each side. Second instar female similar to adult female in pygidial margin, outer lobule of second trulla conical. First instar female head with a pair of enlarged dorsal ducts. Antennae 6 segmented, terminal segment not annulate, as long as preceding segments combined. Second-instar male, Heteromorphic, with small ducts strewn on abdomen. With small gland spines marginally on pygidium, otherwise with no marginal appendages. (Takagi, 2007a)
• Biology: Female and male tests occurring on the leaves; female tests more abundant on the upper surface and male tests on the lower surface. Female test elongate, convex dorsally, irregularly incised laterally and variously curved owing to dense hairs of the leaves, thite, with exuvial casts brown. Male test non-carinate, erect. The body of the adult female is usually distorted often badly, in accordance with the irregularly shaped test. (Takagi, 2007a)
