Short description Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 6; Anal soft rays: 9 - 11. A member of the Microglanis parahybae species complex on the basis of color pattern which differs from other species of the genus by having the following combination of characters: paired and anal fins mottled or with thin faint bands, trunk with dark-brown saddles, anterior margin of pectoral spine with serrations retrorse proximally and antrorse distally, tip of pectoral spine as a distinct bony point, continuous portion of lateral line reaching vertical through last dorsal-fin ray, caudal peduncle with irregularly shaped, faint to dark blotch, maxillary barbel surpassing vertical through dorsal-spine origin, and dark bar on posterior flank continuous from base of adipose fin to that of anal fin (Ref. 79079).

Biology     Glossary (e.g. epibenthic)

Occurs in moderately flowing sections of streams with dark brown water and bottom of sand and mud. Collected using a dip net under floating vegetation at a depth of 1.5 to 2 m (Ref. 79079). Two specimens have stomach contents consisting of algae and insect larvae (Ref. 79079).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months ().
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
