Hosoishi and Ogata (2015) - Examination of syntype queens in MHNG and NHMB reveals that C. popohana amia Forel, 1913 is quite different from Crematogaster popohana Forel, 1912. In the original description, Forel (1913) also suggested that the males of C. popohana amia Forel, 1913 are distinctly larger than the ones of C. popohana Forel, 1912. The taxonomic status of this subspecies remains uncertain.

Type Material
Hosoishi and Ogata (2015) - Three syntype queens and three syntype males from TAIWAN: Taihorin and one syntype queen  [examined].
