In museum specimens, the thin bill is clear and there is a long exposed nasal groove along the bill. The rictal bristles are short and few and the feathering at the base of the beak is reduced giving a very pointed face profile. The lower mandible is not flesh coloured in tytleri as it is found in most trochiloides and it is not dark black as in Phylloscopus collybita tristis. They do not have any wing bars.
