New Gastropods from the Gulf of Mexico (Northwestern Florida, the Yucatan Peninsula, and the Flower Garden Reefs of Texas)

Abstract

Three new species of gastropods are described from the Gulf of Mexico. These include: Fasciolaria ixchel n.sp. (Fasciolariidae) from near Isla Mujeres on the eastern side of the Yucatan Peninsula of Mexico; Jaspidiconus forticostatus n.sp. (Conidae) from the Big Bend area of northwestern Florida; and Jaspidiconus hortusensis n.sp. (Conidae) from the West Flower Garden Reef southeast of Galveston, Texas. The eastern Yucatan fasciolariid is the newest member of a previously-overlooked complex that contains four closely-related Fasciolaria s.s. species that are endemic to the Gulf of Mexico. The two new cones are members of a complex containing ten species of Jaspidiconus that are now known to be inhabit shallow water areas around the Gulf of Mexico.
