Remarks
- Systematics: Protodiaspis didymus is very near P. agrifoliae, differing from it in the absence of perivulvar pores, these structures being present in P. agrifoliae (McKenzie & Nelson-Rees, 1962).
- Structure: Slide-mounted adult female 0.6 mm long, ovoid. Derm membranous. The margin of pygidium is quite regularly crenulate, without lobes, plates, or gland spines. Perivulvar pores absent. Minute tubular ducts abundant over entire dorsal and ventral surfaces, those on venter slightly smaller than on dorsum (McKenzie & Nelson-Rees, 1962).
- General Remarks: Detailed description and illustration by McKenzie & Nelson-Rees, (1962). Description and illustration of first instar by Howell & Tippins (1981a).
