Systematics: Chionaspis brachycephalon Vea differs from other Chionaspis by the following combination of characters : small head, gland spine formula variable from 1-1-1 to 2-2-2 (median: 2-2-2), microduct formula also variable from 2-2-2 to 3-3-4 (median: 3-2-2); numerous marginal gland spines on abdominal segments 3 to 5, absent from abdominal segment 1 and 2; variable number of notches present on all pygidial lobes. (Vea et al. 2012)
Structure: All pine-feeding Chionaspis discussed in Vea et al (2012), including C. heterophyllae and C. pinifoliae, are indistinguishable by eye in the field. The adult female for all species possesses a white oystershell-shaped and slightly convex cover, with the amount of posterior expansion varying according to the diameter of host needles. Body elongate, color varying from yellow when immature to reddish brownish in specimens containing eggs, with lateral protrusion on the anterior abdominal segments. Found on needles. (Vea et al.2012)
