Systematics: Rolaspis monile comes closest to P. procera, but differs in having many fewer dorsal ducts and also in the character of the marginal pygidial ducts which are normal instead of possessing microducts on the capitate heads (Williams, 1960c).
Structure: Female scale shiny white, elongate, about 2.5 mm long, exuviae pale brown. Male scale white, 1.0 mm long. Adult female elongate-oval, 1.75 mm long. Dorsum at maturity becoming sclerotized in a characteristic fashion. Pygidium with a small ring situated towards base. With two pairs of lobes; median lobes very short and wide, slightly divergent with a distinct U-shaped notch between and yoked at the base by a narrow sclerotized band, posterior edges straight and divergent; 2nd lobes bilobed, inner lobule about as long as wide and projecting further than median lobes, apex rounded, outer lobule similar in shape but much smaller (Williams, 1960c).
