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.

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 1; Dorsal soft rays (total): 7; Anal spines: 0; Anal soft rays: 16 - 18; Vertebrae: 50 - 52. Four patches of conical teeth across front of palate; rounded vomerine patches well-separated; outer patches oval or crescentic, 2-3 times larger than inner patches. Snout fleshy, overhanging mouth. Low papillae on palate and posterior face of gill arches; rakers rarely on posterior face of first two gill arches. Barbels thick proximally, thin distally. Head shield very granular, extensive posteriorly; triangular supraoccipital process short, broad. Eye small, dorsolateral. 8-12% HL. Adipose fin large, base longer than anal fin base. Dark grey in color; inner, dorsal aspect of paired fins charcoal blue (Ref. 40908).
Inhabits muddy, shallow coastal waters and tidal rivers (Ref. 40908).
