Bulbuls (Pycnonotidae)

Appert's Tetraka (Xanthomixis apperti) - HBW 10, p. 249

French: Bulbul d’Appert German: Appertbülbül Spanish: Bulbul de Appert
Other common names: Appert’s Greenbul

Taxonomy: Phyllastrephus apperti Colston, 1972, 40 km south-east of Ankazoabo, south-western Madagascar.
Relationships of genus with rest of family uncertain. Genus previously merged with Bernieria, but recent mitochondrial DNA sequence data indicate that the five species then involved are not a monophyletic group. Hence, this species and its relatives better placed in present genus. Recent molecular data indicate that present species is sister of X. cinereiceps. Monotypic.

Distribution: Zombitse and Vohibasia forests (near Sakaraha) and Analavelona forest, in SW Madagascar.
