Etymology: Luciogobius: Latin, lucius = pike + Latin, gobius = gudgeon (Ref. 45335); fluvialis: The specific name, 'fluvialis', is a Latin adjective, meaning flowing or riverine. This is in refence to the habitat of this species..

Morphology | Morphometrics
soft rays: 8 - 10;
Vertebrae: 31 - 33. Diagnosed from all other species of Luciogobius by having the following combination of characters: eye small and degenerated, embedded beneath skin, obscured after fixation; body naked, without scales; dermal ridge on cheek lacking barbels; second dorsal-fin origin slightly anterior to anal fin; pelvic fin present; no free soft rays on upper and lower ends of pectoral fin; second dorsal-fin rays modally I,9; anal-fin rays modally I,9; branched caudal-fin rays modally 8+7; vertebrae modally 16+16=32; interorbit region flat; maximum width of head at cheek 11.5% in SL; upper jaw length 8.5% in SL; 37.4% in head length; predorsal length 307.4% in head length; and preanal length 315.8% in head length (Ref. 86963).
Found in the middle reaches of river on a gravel substrate composed of pebbles of 3-5 cm in diameter and containing less than 5% of sand, where freshwater springs flow from between the pebbles (Ref. 86963).
