2C0387DCFFCFFFA6C1C35080FE01297B.taxon	diagnosis	is easily differentiated from O. ferreirai by its lower dorsal (42 to 50 vs. 52 to 57 in O. ferrerai) and anal-fin rays (49 to 58 vs. 61 to 66 in O. ferrerai) counts. In addition, O. bicirrhosum possess fewer lateral-line scales (30 to 37), while O. ferreirai possess 37 to 40 (Escobar et al. 2013). The specimen CICCAA 03485 (fig. 4) was identified as O. bicirrhosum since its counts are within this species range: this specimen has 44 dorsal-fin rays, 50 anal-fin rays, and 35 lateral-line scales (right side; scales from left side are damaged near caudal fin). Specimen MPEG 020719 was identified by the MPEG staff (A. Ferreira).	en	Oliveira, Rafael Ferreira de, Vieira, Lucas de Oliveira, Guimarães, Erick Cristofore, Brito, Pâmella Silva de, Ottoni, Felipe Polivanov (2021): First record of Osteoglossum bicirrhosum (Cuvier 1829) (Osteoglossiformes: Osteoglossidae) for the state of Maranhão, Brazil.
