Systematics: The adult females are most readily distinguished from those of closely related Tachardiella species found in the southwest USA by having prominent dorsal ducts that are nearly as broad as long. (Kondo & Gullan, 2011)
Structure: Solitary or lightly massed on stem of host; solitary individuals show distinct lobations; lac somewhat variable in color, between a burnt sienna and brown ochre. (Kondo & Gullan, 2011)
General Remarks: Good description and illustration of the adult female given by Chamberlin (1923).
