Mysidopsis gemina n. sp. is described from protected and exposed beach
habitats in the provinces of Puntarenas and Guanacaste on the northern
Pacifc coast of Costa Rica. Morphologically, M. gemina most closely
resembles M. furca Bowman, 1957 known from the Atlantic and Gulf Coasts
of North America. Both these species are unique within the genus by their
distinctively sexually dimorphic telsons. Te new Costa Rican species
can be distinguished from M. furca and other species of Mysidopsis by a
combination of having a male with biarticulated endopods on the frst
pleopods and pleopods 2–5 with large plate-like pseudopodia (exites).
Te occurrence of these characters and morphological features within the
subfamily Leptomysinae is discussed
