Systematics: Pseudodiaspis larreae is distinguishable from any known species by the turbinate body, of which the thoracic region is quite heavily sclerotized both dorsally and ventrally (Ferris, 1937).
Structure: Female scale 2.0 mm in diameter, flat, irregular, round to suboval, dull white with a slightly creamy tint; exuviae not visible in mature scale, but in younger scales the elongate-oval, pale straw 1st exuviae is exposed, sublateral or even lateral. Male scale small, elongate, mytiliform, white. Adult female about 2.0 mm long, turbinate, cephalothorax heavily chitinized. Pygidium quite large, median lobes alone developed, these broad, low, rounded at apex (Ferris, 1921).
General Remarks: Detailed description and illustration by Ferris (1921 & 1937).
