Key to the species of Mysidae in fresh and oligohaline waters of the Mediterranean

All species indicated below belong to the subfamily Mysinae Haworth, 1825 . Twelve species plus two nonnominotypical subspecies are so far known from fresh and oligohaline waters of the Mediterranean. In order to cover potential future invaders, this key includes three additional species that were previously encountered as invaders of warm temperate fresh-waters in any parts of Europe but so far not in the Mediterranean.

1a. Antennal scale setose all around........................................................................ 6

1b. Antennal scale with setose margins except for a large proximal bare portion of the outer margin (and except for a thorn in certain genera)......................................................................................... 2

2a. Outer margin of antennal scale with smooth portion ending in setae. Telson rhombohedral, terminally truncate............................................................................
