| Remarks | Mature males of M. pankilopteryx are easily recognised by the presence of bony hooks on all fin rays. Males and females also differ slightly with regard to pectoral and pelvic-fin lengths (Ref. 56145). |

| Diagnosis |
Moenkhausia pankilopteryx is distinguished from its congeners primarily by the putative autapomorphic presence of bony hooks on all fins of mature males. It is further distinguished from nearly all other members of the genus by the combination of 37–41 pored scales in the lateral line; a caudal-peduncle spot; a deep body, 43.3–51.0 % SL; two humeral spots, of which the first is black, larger and vertically elongate, and the second is dark, very diffuse, and not always visible; two to three maxillary teeth, and analfin rays ii–iv, 24–27 (Ref. 56145). |
