Morphology | Morphometrics
soft rays: 9 - 10;
Vertebrae: 27 - 29. Pseudolaguvia magna is diagnosed from all species of the genus Pseudolaguvia by the possession of the following unique characters: larger body (up to 4.7 cm SL vs. a maximum of 3.56 cm SL); mid-dorsal region with two pale-brown to cream patches (one rectangular to elliptical patch on mid-interdorsal region, and another indistinct elliptical patch in between the adipose and caudal fins); broader rhomboidal thoracic adhesive apparatus; small pale-brown to cream round spot on the ventrolateral side of the head, almost perpendicular to the eye; and absence of pale-brown to cream-colored cross-bands on the body (which it shares with P. inornata, P. austrina, P. virgulata and P. assula) (Ref. 98400).
Found in stream with clear, moderately flowing water. Occurs syntopically with Pseudolaguvia jiyaensis. Both Pseudolaguvia jiyaensis and Pseudolaguvia magna were collected along with species of Psilorhynchus, Barilius, and Danio from the same collection locality in a microhabitat consisting of small to medium-sized stones, pebbles, cobbles with light green algae, and deposits of sand particles near banks (Ref. 98400).

= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00252 - 0.01200), b=3.04 (2.85 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.5 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.).
Vulnerability (Ref. 59153
