Etymology: hardenbergi: Named for J.D.F. Hardenberg who recognized this species as new, as well as for his insightful contributions to the Indo-Australian ichthyology in the mid-twentieth century (Ref. 40908).
Issue
This species is placed in the genus Hemiarius in Eschmeyer (CofF ver. Jul. 2011: Ref. 87661) following Marceniuk & Menezes (2007: Ref. 58022). It is treated here under the genus Aspistor following Ferraris (2007: Ref. 58032). Please send references, or more studies are needed.
