Race olivaceiceps was split from A. milanjensis in 1990#R but it belongs with nominate striifacies. Although iris colour apparently variable and thus no clear taxonomic indicator, species differs from A. milanjensis in its olive-green vs dark grey crown (3); lack of white crescent above eye (2); little or no greyish-white on throat (1); black vs grey lores (ns[1]); slightly brighter green underparts (ns[1]); and larger size, albeit bill same size (effect size for tail 3.29; score 2). Moreover, song without final trill apparently heard only from A. milanjensis (no score until sample larger [2]), but song of presumed striifacies in Taita Hills on current evidence different from that of others and rather closer to A. milanjensis song, suggesting need for further work at that site#R. Two subspecies recognized.
