Bulbuls (Pycnonotidae)

Sassi's Olive Greenbul (Phyllastrephus lorenzi) - HBW 10, p. 215

French: Bulbul de Lorenz German: Lorenzbülbül Spanish: Bulbul de Lorenz
Other common names: Sassi’s/Lorenz’s Greenbul

Taxonomy: Phyllastrephus lorenzi Sassi, 1914, Moera, near Beni, eastern DRCongo.
Taxonomic status unclear; vocal and molecular data needed. Has been suggested that it forms a superspecies with P. baumanni, P. hypochloris and P. poensis, but affinities with these seem remote. Relationship with P. icterinus requires analysis; the two are almost entirely sympatric, closely similar in structure, overlap in dimensions, and appear also to intergrade in crown colour; possibly a melanistic form of that species. Monotypic.

Distribution: Scattered localities in NE & E DRCongo; one record from extreme W Uganda (Bwamba).
