was established based on very few characters. The diagnostic characters provided by Rafinesque (1815) were concise and focused only on the antennae (Rafinesque 1815: 98). Additional characters that could be diagnostic of this family are: the rostrum is often prominent, possibly toothed, and the first and second pereopods chelated, the second larger, without subdivisions of the carpus (Williams 1984; Wicksten 2005). Although the antennae and the chela of the first pereiopod are not discernible on the material, the other characters cited above are shared by
