Etymology: Microglanis: Greek, mikros = small + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335); robustus: The specific name 'robustus' is derived from the Greek adjective, in reference to the truncated body and high caudal peduncle, giving a strong format to this catfish.

背面の脊椎 (合計) : 1; 背鰭 (合計) : 6; 臀鰭: 9 - 11; 脊つい: 27 - 28. Distinguished from all its congeners by having a cordiform blotch in the nape (instead of a transverse light stripe), neuromasts of the superficial lines surrounded by melanophores on trunks, robust body with short snout, head and predorsal distance, and deep caudal peduncle. Further differs by the combination of the following characters: three wide brown blotches at lateral of body; light brown vermiculations on trunk and caudal peduncle; mouth width 11.4-13.2% SL; snout length 9.1-10.7% SL; interorbital width 44.4-49.1% HL; head length 25.5-27.8% SL; predorsal length 35.6-38.5% SL; body width 25.0-27.7% SL; adipose-fin base length 24.5-28.0% SL; caudal peduncle length 14.2-17.4% of SL; caudal-peduncle depth 13.5-14.7% SL; anal fin with 9-11 rays; pectoral-fin spine with 6-8 serrations on posterior margin; and 4-8 gill rakers. (Ref. 85327).
Found in rapids. This represents the first Microglanis species encountered in rapids as all other species occur among marginal submerged vegetation, depositional substrata of leaves, and/or trunks in calm water stretches of rivers (Ref. 85327).
