Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 6 - 7; Radios blandos dorsales (total) : 7 - 9; Espinas anales: 1; Radios blandos anales: 6 - 8; Vértebra: 27. This species is most similar to Rhinogobius wuyanlingensis in number of vertebrae (27) and preopercular canal pores (2 or 0 vs. 2); differs by having fewer pectoral-fin rays 14-15 (vs. 17-18 in R. wuyanlingensis), fewer anal-fin rays I, 6-7 (vs. I, 8), fewer transverse scales 7-9, modally 8 (vs. 9-10); in males, anterior part of first dorsal fin without a black blotch (vs. present) and with branchiostegal membrane mostly reddish-orange, with irregular blotches posteriorly (vs. with red stripes) (Ref. 119419).

Occurs usually in shallow (10-50 cm deep) low-gradient streams (Ref. 119419).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00724 (0.00338 - 0.01553), b=3.05 (2.87 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

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