Systematics: The strongly sclerotic points representing the 2nd and 3rd lobes distinguish this species immediately from others in the genus (Ferris, 1937).
Structure: Female scale circular, about 0.75 mm wide, slightly convex and of a distinctly yellowish color; exuviae subcentral, the 1st naked, the 2nd covered with secretion; ventral scale quite thick. Male scale white, elongate with an obscure median carina and with the exuviae at one end. Adult female 1.0 mm long, turbinate, thorax not separated from the abdomen by a constriction, the abdominal segments projecting but little at the margins. Pygidium rather acute at apex. Median lobes quite large, prominent, straight and with their apices nearly truncate. 2nd and 3rd pairs consisting merely of an acute prominence (Ferris, 1921).
