Systematics: Protodiaspis lagunae differs from P. lobata and P. parvula in the presence of the circumgenital pores and from P. agrifoliae in the presence of well developed lobes (Ferris, 1921b).
Structure: Female scale more or less circular, less than 1.0 mm in diameter, variable in size and form in conformity with its environment, quite highly convex, normally well formed, but in certain cases where the insect is deeply buried in a crack the scale is composed merely of loose threads. Male scale elongate, white, non-carinate, with exuviae at one end. Adult female 0.5-0.6 mm long, broadly oval; derm membranous throughout except for a slight chitinization of the pygidium and sometimes of the anterior portion of the body. Pygidium with 2 pairs of weakly chitinized lobes which are frequently very obscure; with a few very minute and scattered dorsal ducts and with the circumgenital pores present in 5 groups which in some specimens are nearly confluent. Adult male apterous, body terminating in a long style, the head with a dorsal and a ventral pair of ocelli, the body entirely hairless, the antennae 9-segmented, very slightly clavate (Ferris, 1921b).
