Remarks

• Systematics: The ventral tubular ducts of this species, each with a very short, swollen inner ductule, form a submarginal band, a characteristic typically found in the C. floridensis-group. It closely resembles C. planus due to the absence of multilocular disc-pores on the thorax and abdomen anterior to segment VI, but differs from the latter (character states for C. planus given in parentheses) in having the following character combination: (i) stigmatic clefts each with 26–29 bullet-shaped setae (5–14); (ii) microducts along the body margin absent (present). (Li & Wang, 2025)
• Structure: In life: Wax test of adult female oval or subcircular in outline, flat or slightly convex in pre-reproductive female, and strongly convex in post-reproductive female, 2–3 mm in diameter, and 1.3–1.7 mm high. Dry wax filaments as follows: cephalic filament appearing trifurcate; anterolateral and mediolateral filaments simple; posterolateral and caudal filaments bifurcate. In the first- and second-instar female stages, the dorsal dry wax forms a small, forward-inclined cap.
  Dorsal derm membranous in pre-reproductive female adult except for heavily sclerotized caudal process. Number of clear areas variable, 9 or 11 in pre-reproductive individuals, 7 in reproductive or post-reproductive ones, mediodorsal area absent. Marginal setae each setose, all curved and with sharp apex. Ventral derm entirely membranous. Antennae each 218–256 μm long, with 6 segments. (Li & Wang, 2025)
