Etymology: Microglanis: Greek, mikros = small + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335); leptostriatus: Derived from the Greek lepto (slender) and striatus (stripe), in reference to the distinct light transverse stripe in the nuchal region.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 6; Anal soft rays: 9 - 12. Distinguished from its congeners by the following combination of characters: light transverse stripe, situated in occipital region between the opercular openings, thin and sinuous, sometimes discontinuous; pale region below dorsal and adipose fins mottled with brown spots; dark stripe in the axis of gill filaments in alcohol preserved specimens. Differs further from Microglanis parahybae and Microglanis garavelloi, the closest species geographically, by the following combination of characters: longer head length (28.3-32.1% SL vs. 25.5-28.5% and 25.2-30.2, respectively), shorter dorsal spine length (11.7-14.9% SL vs. 14.1-18.1% and 11.3-19.0), shorter pectoral spine length (12.5-19.7% SL vs. 19.4-22.7% and 18.5-26.2) (Ref. 58766).

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=0.01023 (0.00525 - 0.01996), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
