Systematics: Protodiapis emoryi is most closely related to P. colimae (Ferris, 1937). It is readily recognized by the pygidium being short and broad and with only dorsal longitudinal furrows. These furrows divide the pygidium into 5 rather weakly defined areas which are not indicated on the ventral side (McDaniel, 1973).
Structure: Female scale in cracks of host bark, but not usually deeply hidden, quite well formed, shape depending on environment. Male scale definitely formed, minute. Adult female turbinate, derm of head and thoracic region becoming quite heavily sclerotic, both dorsally and ventrally at maturity and the pygidium likewise heavily sclerotic. Dorsum and margins of the venter with numerous minute ducts. Pygidium somewhat elongate, marked with heavy furrows both dorsally and ventrally. Vulva well forward of the anus. Perivulvar pores lacking (Ferris, 1937).
General Remarks: Detailed description and illustration by Ferris (1937).
