Four New Species of Zosimeidae (Copepoda: Harpacticoida) from the Southwestern Gulf of Mexico

As a part of ongoing efforts for monitoring benthic ecosystem in the Gulf Mexico, Harpacticoid copepods were collected from southwestern Mexico. Among them we report three new species Zosime, and Peresime study area. Zosime is most specious-rich genus family. Three morphologically similar to Z. paratypica Becker Schriever, 1979, atlantica Bodin, 1968, destituta Kim J.G., Jung Yoon, 2016, respectively. However, all have unique characteristics that distinguish such as setal formulae shape female P5 caudal rami. The has morphological characters with P. reducta (Becker 1979). These two can be distinguished by differences mouth parts length setae on P2. This first genera We also discuss global diversity distribution Zosimeidae provide key family each genus, including four
