Subspecies
Close to the superspecies formed by Dark-necked Tailorbird (Orthotomus atrogularis), Chestnut-crowned Tailorbird (Orthotomus castaneiceps) and Rufous-fronted Tailorbird (Orthotomus frontalis). Meets subspecies chloronotus of Chestnut-crowned Tailorbird (Orthotomus castaneiceps) but, despite superficial similarities in plumage and vocalizations, the two behave as separate species. Supposed "intermediate" specimens have been shown to be juvenile or immature of present species.

The following 2 subspecies are recognised:

derbianus Moore, 1855 - Southern Luzon (southern from Pangasinan and Nueva Vizcaya Provinces), in north-central Philippines.
nilesi Parkes, 1988 - Catanduanes, off south-eastern Luzon.
