With 1 to 4 unkeeled and irregular scutes without vertical arms; pelvic scute with vertical arms (not W-shaped, cf. Spratelloides, Dussumieria); no post-pelvic scutes. Snout pointed, lower jaw a little prominent, small but distinct teeth in each jaw; second supra-maxilla long; gill rakers on hind face of third epibranchial (cf. absent in Ehirava fluviatilis).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00871 (0.00366 - 0.02072), b=3.03 (2.83 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.3 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.).

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

Price category (Ref. 80766): Low.
