Etymology: Nemacheilus: Greek, nema, -atos = filament + Greek, cheilos = lip (Ref. 45335); stigmofasciatus: the specific name stigmofasciatus is a combination of the Greek words stigmo for blotch and fasciatus for band, due to the regularly sized blotches alternating with bands (Ref. 80640).

Short description Identification keys | Morphology | Morphometrics

Distinguished from the other two peninsular Indian species N. anguilla and N. monilis by its colouration and a set of morphometric characters. The species differs in having a lateral line that extends to the pelvic fin base below (vs. reaching up to anal fin in N. anguilla and complete in N. monilis), shorter snout length (35.9-39.4% HL vs 46.8% HL in N. anguilla and 40.5-48.1% HL in N. monilis), bigger eye (28.1-31.3% HL vs 23.0% HL in N. anguilla and 15.9-19.9% HL in N. monilis), caudal peduncle shorter than N. anguilla (12.4-13.1% SL vs 15.5% SL) and shallower than N. monilis (9.5-10.2% SL vs 12.0-14.5% SL). Vent to anal distance is reduced compared to N. anguilla (29.7-34.5% vs 40.6% Pelvic to anal distance) and greater than N. monilis (29.7-34.5% vs 16.9-25.9% Pelvic to anal distance). Notable colour variations are the lesser number of bands on dorsal (back) 11-13 (vs 19-20 in N. anguilla and N. monilis), 6-8 blotches evently spaced along the lateral line (vs. band formed of coalescing blotches extending to caudal base in N. anguilla and monoliform band in N. monilis (Ref. 80640).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00724 (0.00347 - 0.01512), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.8 ±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).
