Bryconamericus ichoensis can be distinguished by ilS small size, absence of a spot on the caudal peduncle, and generally 27 to 30 anal fin rays. B. ichoensis may be closely related to B. multiradiatlls, but can be distinguished by the number of unbranched rays in the dorsal, pectoral and pelvic fins, the number of predorsal scales, body depth, etc. Bryconamericus galvisi, can be distinguished from other species ol' Bryconamericus by its single peduncle spot, high branched anal fin ray, ¡he lateral line scales count, and elongated body.
