Panov 2009. On the nomenclature of the so-called Isabelline Shrike. Sandgrouse 31(2): 163-170.
En Panov argues for the retention of the old nomenclature, contra Pearson (2000) who suggested that isabellinus be used for the taxon previously known as speculigerus, and arenarius for the taxon previously known as isabellinus.
But Pearson's arrangement has been very widely adopted - Dickinson 2003 (H&M3), Cornell/Clements, HBW, BOU, CSNA, most recent field guides etc etc - so a reversal now would be a major headache. :eek!:
Incidently, Panov supports a single split resulting in Lanius isabellinus Isabelline Shrike (with ssps tsaidamensis & speculigerus) and L phoenicuroides Turkestan Shrike (monotypic).
