Currently valid species include:[1]

Limulus polyphemus (Linnaeus, 1758)
Limulus coffini† Reeside & Harris, 1952- Pierre Shale, United States, Late Cretaceous (Maastrichtian)

Doubtful species include:[2]

Limulus nathorsti† Jackson, 1906- Jurassic, Sweden

Tentative species:[2]

"Limulus" decheni† Zinken, 1862- Paleogene, Germany (considered by some intermediate between Limulus and Tachypleus)[2]
