Systematics: The unusual number of rows of dorsal ducts make this species quite easily recognizable (Ferris, 1955d).
Structure: Female scale 2.75 mm long, 1.75 mm white, snow white, broad, flat; exuviae clear orange. Male scale small, white, with no distinct keel, not fluffy, exuviae orange. Adult female with brown median lobes which are wide apart, even at the base, diverging, low, little produced, the longer inner margin crenate. 2nd and 3rd lobes each represented by a pair of rounded lobules, of which the mesad is the larger (Craw, 1896).
General Remarks: Detailed description and illustration by Ferris (1955d). Cheo (1935) reported this species from the United States in California but this distribution record has not been confirmed by any other author and apparently is an error.
