Until recently treated as conspecific with L. poensis, but differs from L. p. camerunensis in its deep brown or reddish-brown vs grey iris (based on multiple labels in NHMUK, contra published description#R) (2); slightly less glossy black plumage at least on breast (constant in NHMUK series) (1); shorter bill (effect size for males −2.39, score 2); long pure whistles as typical call vs short single or double notes or rapid repetitions (3). Molecular evidence#R supports this split. Monotypic.
