Dorsale zachte stralen (totaal) : 8 - 10; Anale stekels: 1; Anale zachte stralen: 8 - 10; Wervels: 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).
Body shape (shape guide): fusiform / normal.

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).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00977 (0.00444 - 0.02153), b=3.04 (2.85 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.2 ±0.5 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100). 🛈
