Systematics: Duplachionaspis distichliii is distinguishable from other North American species by the mixture of large and small dorsal ducts, mostly smaller than the marginal ducts of the pygidium and those of the 6th segment not in a row; perivulvar pores in much smaller groups; submarginal setae of the ventral side of the pygidium enlarged (Ferris, 1937).
Structure: Female scale narrow, about 1 mm long, 1st exuviae naked, 2nd covered with secretion. Male scale slightly shorter than that of female, non-carinate. Adult female .75 mm long, derm membranous throughout except for pygidium (Ferris, 1921).
Biology: Duplachionaspis distichlii occurs on the upperside of host leaves (Ferris, 1937).
