Remarks

• Systematics: This species is externally similar to C. decorata, but C. biloba can be distinguished from the latter by 1) presence of 5 or 6 plates lateral to L3 (C. decorata without plates lateral to L3); and dorsal ducts irregularly distributed along the margin and submargin, but distributed in C. decorata forming 2 rows, distributed along the submargin. (Wei & Feng, 2011)
• Structure: Color of the scale very variable, apparently changing with age. In some of the specimens above the surface of the ground the scale is white, in others it is almost straw colored, while in others beneath the surface and subjected to the staining action of the soil and perhaps to fungi, the scale is black. Scale of the female quite thick and with a thick ventral portion; quite convex, irregularly circular or slightly oval. Scale of the male slightly elongate, white or straw colored (Ferris, 1946).
• Biology: Occurring at the base of the leaves, on the rootstock and even on the roots (Ferris, 1946).
• General Remarks: Description and illustration of adult female by Ferris (1946) and by Chou (1985, 1986).
