Probably closest to O. enganensis and O. umbra. Original specimen, collected in 1966, initially listed as race nicobaricus (= modestus) of O. sunia, though long wings unlike all forms of that species; second specimen collected in 1977, and the two suspected of belonging to an undescribed taxon, tentatively placed with an “expanded” O. magicus. Subsequently treated again as race nicobaricus (= modestus) of O. sunia, or as a form of O. magicus without subspecific allocation, but in one case listed as “Otus sp”. Recent examination of both specimens, along with comparisons with all other Otus taxa of non-mainland SE Asia (N to Philippines), led to conclusion that they were sufficiently distinct in plumage and morphology to warrant recognition as a separate species. Monotypic.

Distribution:

Great Nicobar I, in extreme S Nicobar Is.
