White-browed Shrike-babbler (Pteruthius aeralatus)


Taxonomy

French: Allotrie de Blyth German: Rostflügel-Würgervireo Spanish: Vireo alcaudón cejiblanco
Taxonomy:

Pteruthius æralatus

Blyth

, 1855,

mountainous interior of Tenasserim, Myanmar

.

Until recently considered conspecific with P. flaviscapis (which see). Molecular and vocal evidence invoked to reinstate and even elevate to species rank the form ripleyi#R#R, which was treated as a synonym of validirostris in HBW but here accepted as a race (recent recordings revealing situation to be far less clear-cut than claimed#R); similar criteria invoked to elevate annamensis to species rank#R#R, but more conclusive information on diagnostic characters is required in order to validate any further splitting of this species. Proposed race lingshuiensis (Hainan) included in ricketti. Populations in Peninsular Malaysia currently included in race cameranoi, but are in fact intermediate between that taxon and schauenseei. Eight subspecies recognized.
