Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 6; Rayons mous anaux: 22 - 25. Differs from all other species of the genus Gladioglanis by the following characters: absence of dorsal-fin spine and spinelet absent; first dorsal-fin ray (homologous to spine) flexible, unbranched, followed by five branched dorsal-fin rays; pectoral-fin spine 5.8-6.1% of SL; pectoral spine with 5 dentations on anterior side and 4 on posterior; anal fin with 22-25 rays; round profile of the head in dorsal view; first pterygiophore of dorsal fin in contact with neural spine of eighth vertebra; both caudal-fin lobes with 13 rays; and total vertebrae 60 (Ref. 79081).
Found in flooded forest on the border of the lake, in a shallow (up to 0.5 m) marginal area on a deep mat of leaf litter as substrate. Also collected on leaf litter along the shore of the lake (Ref. 79081).
