Etymology: Microglanis: Greek, mikros = small + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335); minutus: Named from the Latin 'minutus', meaning small, in reference to its smaller size compared with all other congeners.

Morphology | Morphometrics
soft rays: 12 - 14;
Vertebrae: 28. Distinguished from all members of the Microglanis parahybae species complex by the following combination of characters: pectoral and anal fins mottled or with relatively faint bands; caudal fin emarginate; dark brown saddles on trunk; caudal peduncle with faint to dark blotch irregularly shaped; caudal fin lightly mottled with narrow vertical dark brown band across central portions of lobes; dark saddle beneath adipose fin not extending ventrally to anal fin as continuous bar; continuous portion of lateral line not reaching vertical through origin of adipose fin; tip of pectoral spine as distinct bony point; wider head; a dark blotch beneath adipose fin not extending to anal fin; distal portion of anal fin without dark band; dark saddle beneath adipose fin extending ventrally to more than the half of trunk and a light oval spot located below dorsal-fin spine (Ref. 86273).

Phylogenetic diversity index (Ref. 82805
= 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), in cm total length, 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. 120179
): High, minimum population doubling time less than 15 months ().
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
