Gymnotus pantanal further differs from other members of the G. pantherinus species-group in possessing a wider head (72–77 vs. 52–69% head length). Gymnotus pantanal further differs from G. anguillaris in possessing more narrowly set eyes (37–41 vs. 43–56% head length), a deeper head (66–74 vs. 60–65% head length), larger branchial openings (38–43 vs. 29–36% head length), longer pectoral fins (51–56 vs.42–50% head length), more pectoral-fin rays (mode 17 vs. 16), and fewer pored posteriorlateral-line scales (to first ventral ramus: 47–58 vs. 58–62; total: 102–114 vs. 124–130).
