It looks as if the Glossy Swiftlet's I saw in Malaysia last year have now been split (along with 9 other new species), following MDNA analysis of this broad ranging species. The species found in Peninsula Malaysia (as well as Borneo, Sumatra, Natuna and the Andaman and Nicobar Islands) has been renamed Plume-toed Swiftlet Collocalia affinis according to findings published here by the ICO.
Unfortunately the differences between the new 'splits' are not obvious in the field. Such is the complexity of birding in modern times.
