Major taxonomic references list the species as Lampropeltis triangulum (Lacépède, 1789), not 1788. ITIS explicitly notes that 1788 is a common miscitation and explains why: Lacepède's snakes were published in volume 2 (1789), not in the 1788 volume. The Reptile Database also uses 1789 for both the species name and the original combination Coluber triangulum.

Because the article gives "Lacépède, 1788" for this taxon, that date is incorrect.

The infobox presents "24 subspecies" as the current subspecies count, but current authoritative taxonomic sources do not support that.

• The U.S. Fish & Wildlife Service taxonomic tree for Lampropeltis triangulum shows Subspecies: 0 under the species.
• The Reptile Database lists only two subspecies under Lampropeltis triangulum: L. t. syspila and L. t. triangulum.

Taxonomic treatments differ on the exact modern arrangement, but these current references agree that 24 is not the accepted present-day count. So presenting the species as having 24 subspecies is outdated and misleading.
