SYNONYMS: balae, bunguranensis, clarae, dictatorius, fremens, heptneri, herberti, insularum, lancavensis, lucas, luta, macrourus, mansalaris, masae, matthaeus, mayapahit, nasutus, revertens, salanga, stentor, strepitans, stridens, stridulus, tapanulius, tersus, tuancus, ululons, vociférons.

COMMENTS: Appreciable morphological variation exists between samples from north and south of Isthmus of Kra, and among insular samples from the Sunda Shelf; systematic revision is required to assess whether variation is characteristic of one or more than one species (Musser, 19816). The name macrourus has priority over sabanus, but is based on a specimen of uncertain origin (Musser, 19816).
