Etymology: Stenogobius: Greek, stenos = narrow + Latin, gobius = gudgeon (Ref. 45335); caudimaculosus: The name is derived from the Latin words cauda meaning tail and maculosus meaning spotting. This is in reference to the spot or spots that exist on the caudal peduncle of this species.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00444 - 0.02358), b=3.05 (2.86 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (17 of 100) .
