Abstract
In 1899Reichenow described an african bushshrike in juvenile plumage as a new species. He named itLaniarius dubiosus. DNA from type material (feathers and skin) was extracted and DNA sequences from the mitochondrial Cyt-b gene were analysed. Comparisons of DNA-sequences from other bushshrikes (including the type-specimen from Luehder's bushshrikeLaniarius lühderi) support the judgement that “dubiosus” does not represent a full species rather than a representative of the western subspecies of the Luehder's bushshrikeLaniarius luehderi.
Zusammenfassung
Der vonReichenow (1899) als neue Art beschriebene, sich im Jugendkleid befindliche BuschwürgerLaniarius dubiosus ist nach DNA-Sequenzanalysen des mitochondrialen Cyt-b Genes mit hoher Wahrscheinlichkeit ein Jungvogel der westlichen Rasse des BraunscheitelwürgersLaniarius lühderi. Auf der Basis eines DNA-Stammbaumes von sieben verschiedenen Buschwürgern ist der 1991 neu beschriebeneLaniarius liberatus am wenigsten eng mitL. dubiosus verwandt.
