Etymology: Microglanis: Greek, mikros = small + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335); lundbergi: Named for the North American ichthyologist John G. Lundberg, coordinator of the Calhamazon project, who kindly provided specimens of the new species, and for his great contribution to the Systematics of Neotropical catfishes.

Dorsale stekels (totaal) : 1; Dorsale zachte stralen (totaal) : 6; Anale zachte stralen: 11; Wervels: 27. This species differs from all members of the genus Microglanis by having a forked caudal fin with a deep notch between upper and lower lobes, two pale juxtaposed and elliptical spots in the supraoccipital region, and length of the adipose-fin base 13.1-16.6% of SL. It can be separated from other species by the following morphometric characters: length of the head 27.4-30.0% of SL (vs. 24.7-26.4% in M. carlae; 23.9-25.1% in M. iheringi; 23.0-26.1% in M. parahybae; 23.0-25.4% in M. pataxo; 23.5-26.3% in M. robustus); eye diameter 8.0-9.9% of HL (vs. 12.4-17.6% in M. variegatus); interorbital distance 40.4-44.2% of HL (vs. 45.9-51.5% in M. cottoides; 46.5-49.8% in M. leptostriatus; 46.6-48.6% in M. malabarbai; 38.1-39.1% in M. pellopterygius; 50.9-53.1% in M. poecilus); mouth width 38.0-47.3% of HL (vs. 19.0-25.8% in M. cibelae; 17.5-21.9% in M. garavelloi; 20.1-22.6% in M. nigripinnis); predorsal length 35.5-38.6% of SL (vs. 38.9-46.2% in M. eurystoma); lateral line pores 6-8 (vs. 9 in M. ater and M. secundus); principal caudal rays 15 (vs. 14 in M. zonatus) (Ref. 94156).
Body shape (shape guide): elongated.
Found in the main channel of the rio Amazonas (white waters) with bottom rich in organic matter
and pieces of wood (Ref. 94156).
