Relationships with congeners poorly known. W & N populations have been separated out as a full species, H. splendidus with subspecies pyropus#R#R, but not all claimed distinctions substantiated, and differences in any case very slight and apparently only in continuously varying traits, so that validity of taxa not certain; moreover, supposed sympatry of splendidus and viola undermined by possibility of migrant individuals being involved. Monotypic.
