Statius Müller, 1776,
Recent molecular study found this species to form a monophyletic group with C. flavescens and C. lugubris#R. Dark-crowned, short-crested races jumanus and citreopygius sometimes considered to form a separate species, but some representatives of race hellmayri almost as dark on crown, and variations in size and crest length among subspecies render clear taxonomic evaluation of the “jumanus group” difficult; but molecular data#R indicate that jumanus group is sister to C. flavescens (rather than to other races of C. elegans), suggesting that treatment of jumanus and citreopygius as representing a separate species may be appropriate; further study required. Described form roosevelti (from W Mato Grosso) considered a hybrid probably between jumanus and C. lugubris#R. Birds from upper R Branco, in N Brazil, described as race approximans, but appear inseparable from nominate; proposed race saturatus (N Bolivia) indistinguishable from jumanus. Form named as C. immaculatus, known only from type specimen, supposedly from Panama, appears to be an aberrant form of nominate race of present species with erroneous locality data. Six subspecies recognized.
