Systematics: Duplachionaspis albicus is close to D. humilis, but D. albicus differ in having the gland spines shorter than the median lobes and arranged in pairs on some of the segments; the median lobes are not so divergent and the submedian ducts are always scattered (Williams, 1962a).
Structure: Female scale white, elongate, broadening considerably posteriorly, smooth, not transversely striate; about 1.8 mm long. Male scale white with a faint to well developed median keel, parallel-sided, exuviae golden-yellow, about 1 mm long. Adult female broadly oval, typically broadest across mesothorax. Second instar exuviae with submedian dorsopygidial ducts present. First instar exuviae with 5-segmented antennae, apical segment non-annulate. Cephalic margin notched between antennae. Paired dorsocephalic present (Munting, 1977).Female scale white, smooth, elongate, broadened posteriorly, exuviae terminal, 1.8 mm long. Exuviae of second stage brown, but covered in whitish wax. Exuviae of first stage brown. Male scale elongate with a median carina, white; terminal exuviae brown, about 1 mm long. Adult female elongate oval, about 1.2 mm long, membranous except for pygidium (Williams, 1962a).
