Helbig & Seibold's paper, mentioned above, also addresses the taxonomic position of A. (scirpaceus) fuscus and A. (s.) avicenniae, and concludes that under the BSC these two forms are best considered subspecies of scirpaceus.

"Common" Golden-spectacled Warbler     Seicercus burkii
(Burton)   1836
n India; Nepal; Bhutan; e Burma
 

A complete explosion of the Seicercus burkii group has taken place, unfortunately, without the authors proposing vernacular names.  For the time being, I have picked from trip reports, lacking suggestions.  But these proposals are premature, to say the least.

As if it is not enough, two genuinely new taxa in this group have also been described.   References to these can be found here.
