As far as I know, Fusinus luteopictus (Dall, 1877) is a valid species, fairly common in the SW United States. There is another genus (subgenus?) name that I have seen used, but I can't recall it right now. If I remember correctly, the species is covered in Abbott's American seashells, and also in the smaller Field Guide to Seashells of North America, which I believe is also by Abbott. Regards, Paul M.
