Possibly part of a clade which includes also C. verreauxi and C. caerulea#R#R. Hitherto considered conspecific with C. pyropyga. Subspecies maxima known from a single specimen, being “notably larger and with plumage strikingly different” (throat cold bluish-grey vs grey, breast dark tawny-brown vs purplish-grey, lower breast to belly tawny-brown vs whitish; back greyish-blue vs greenish-grey; innermost secondaries blue vs green; uppertail intense violet-blue vs subdued green-tinged blue) such that it “probably merits treatment as a distinct species”; indeed, with separation of C. pyropyga, which isolates maxima from remaining forms of cristata, recognition of maxima as a species appears compelling, but possibility raised that it represents a hybrid with C. caerulea or C. reynaudii#R (latter patently unlikely owing to smaller size of reynaudii, but former conceivable given larger size and blue coloration), although likelihood reduced by report of birds similar to maxima being seen at time and site of collection of type#R. Three subspecies recognized.
