Etymology: Mystus: Greek, mystax = whiskered, used by Belon in 1553 to describe all fishes with whiskers (Ref. 45335);  impluviatus: From the Latin impluvium, referring to a skylight, in allusion to the second posterior fontanel on the supraoccipital of this species..

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 6 - 7; Anal soft rays: 11 - 13; Vertebrae: 37 - 39. Differs from both Mystus castaneus and Mystus nigriceps in having a second posterior fontanel on the supraoccipital. It further differs from Mystus castaneus in having a shallower adipose fin (4.7-6.0% SL vs. 6.1-7.0), smaller serrations on the posterior edge of the pectoral spine (maximum height of serrations 3.6-4.8% of spine length vs 6.9-8.0) and a more deeply forked caudal fin with a more slender upper lobe. Further differs from Mystus nigriceps in having a longer adipose fin base (31.6-36.1% SL vs 26.3-31.4), longer second and third dorsal fin rays, causing the dorsal fin to appear less rounded, and a brown body with a distinct darl triangular patch on the base of the caudal peduncle (vs. greenish gray body with a diffuse dark triangular patch on the base of the caudal peduncle).

Biology     Glossary (e.g. epibenthic)

Facultative air-breathing in the genus (Ref. 126274); Oviparous, distinct pairing possibly like other members of the same family (Ref. 205).

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=0.00832 (0.00384 - 0.01800), b=2.95 (2.77 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec < 10,000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
