Subspecies
Often treated as forming a superspecies with, or conspecific with, Western Mountain Greenbul (Arizelocichla tephrolaema), but differs in plumage and, especially, voice. Recent studies indicate that Western Mountain Greenbul (Arizelocichla tephrolaema) is more closely allied with subspecies kungwensis of Shelley's Greenbul (Arizelocichla masukuensis) of which was originally described under Western Mountain Greenbul (Arizelocichla tephrolaema) (then considered conspecific with present species). Subspecies chlorigula sometimes considered a separate species. Phylogenetic analysis suggests that northern subspecies (nominate, kikuyuensis, usambarae) form a clade only rather distantly related to southern forms (chlorigula, neumanni, fusciceps) and, further, that relationships within latter group may not be very close. Additionally of the forms tested, the northern subspecies appeared to be more closely related to Stripe-cheeked Bulbul (Arizelocichla milanjensis) (of subspecies striifacies) than to southern subspecies of present species, although support for this relationship was not statistically significant. These findings, different from those inferred from morphological studies, have resulted in proposals for elevation of some or, indeed, all subspecies to species level.
The following 7 subspecies are recognised:
kikuyuensis (Shelley, 1890) - Eastern DRCongo (Ruwenzoris south to Mt Kabobo), south-western and south-eastern Uganda, Rwanda, Burundi, and Mt Elgon and central Kenya Highlands. Considered by some authors to be a distinct species, Olive-breasted Greenbul (Arizelocichla kikuyuensis).
nigriceps (Shelley, 1890) - Southern Kenya (Nguruman) and adjacent northern Tanzania (Mt Kilimanjaro and Crater Highlands south to Mbulu and Mt Hanang).
usambarae (Grote, 1919) - South-eastern Kenya (Taita Hills) and north-eastern Tanzania (southern Pare and western Usambara Mts).
chlorigula (Reichenow, 1899) - Esst-central and southern Tanzania. Considered by some authors to be a distinct species, Yellow-throated Mountain Greenbul (Arizelocichla chlorigula).
neumanni (Hartert, 1922) - Eastern Tanzania (Uluguru Mts). Considered by some authors to be a distinct species, Uluguru Mountain Greenbul (Arizelocichla neumanni).
fusciceps (Shelley, 1893) - South-western Tanzania to north-eastern Zambia, Malawi and west-central Mozambique. Considered by some authors to be a distinct species, Black-browed Mountain Greenbul (Arizelocichla fusciceps).
kungwensis (Moreau, 1941) - Kungwe-Mahari Mts, in western Tanzania. Considered by some authors to be a subspecies of Kakamega Greenbul (Andropadus kakamegae). Considered by some authors to be a subspecies of Shelley's Greenbul (Arizelocichla masukuensis).
