New records of anchialine fauna from the Yucatan Peninsula, Mexico

Abstract

New records for 17 species of crustaceans from anchialine systems in the Yucatan Peninsula, Mexico, are presented. The records come from explorations in Dzilam de Bravo, Yucatan, and from Puerto Aventuras and the Nohoch Nah Chich and Ox Bel Ha cave systems near Tulum in Quintana Roo, Mexico. For five of the 17 species dealt with here, the records presented constitute the second time those species are reported after their original descriptions. For the alpheid shrimp Yagerocaris cozumel, we present the first record of the species for continental Yucatan and for the atyid shrimp Jonga serrei, the second record from Mexico. Depth data are provided for all species.
