Systematics: This species is probably related to Chionaspis usambarica (=Voraspis usambarica), but differs in the shape of the median trullae and in other minor respects. The pygidial fringe also resembles that found in Chionaspis dentilobis (=Inchoaspis dentilobis), but apart from the obvious difference of the absence of perivulvar pores in the latter, C. ritchiei has but a single arch of dorsal pores in each series, C. dentilobis (=Inchoaspis dentilobis) has each arch composed of several rows (Laing, 1929a).
Structure: Scale of adult female snowy white, slightly waxy in appearance, long, narrow, broadening posteriorly; larval pellicle pale honey brown, second pellicle a darker brown, overlaid in front with white. Puparium of male snow-white, woolly in appearance, not much longer than pellicle, rather broad posteriorly, uncarinate; larval pellicle very pale yellow-brown, dusted in places with white powder, oval, with a narrow elongate median elevation. Adult female long and narrow, length from three to three and one half times the breadth, widest across penultimate abdominal segment; dorsum with transverse bead-like striae rather widely separated, ventral surface minutely spinulose and closely striated (Laing, 1929a).
General Remarks: Detailed description and illustration by Laing (1929a).
