Abstract
Paradella garsonorum sp. nov., from the high intertidal of Baja California, Mexico, is described and figured, the fourth species from the East Pacific region, the third species from the Gulf of California. It is distinguished from other species of the genus by both uropodal rami having sinuate lateral and mesial margins that provide a notably attenuated appearance to the male uropodal rami, and the pleon with upturned lateral margins. The generic diagnosis is revised, known species in the genus are listed and a key to the eastern Pacific species provided.References
