Meeting Abstract

P1-129  Thursday, Jan. 4 15:30 – 17:30  Two New Species of Sand-Burrowing Amphipods of the Genus Haustorius (Haustoriidae) from the Northwestern Gulf of Mexico HANCOCK, ZB; Texas A&M University, College Station zhancock@bio.tamu.edu

Many undescribed species of the genus Haustorius Muller 1775 have long been known to exist in the Gulf of Mexico. These sand-burrowing amphipods are abundant intertidal members of fine sand beaches. Two new species are here described, Haustorius galvezi sp. nov. and Haustorius allardi sp. nov. The range of H. jayneae is extended to Carrabelle Beach, FL. A review of the genera Haustorius and Lepidactylus is included, as well as notes on their ecology and biogeography. Additionally, a full key to all known Haustoriidae of the Gulf of Mexico is presented.
