Ameroculodes miltoni, a new species of estuarine amphipod (Crustacea: Malacostraca: Peracarida: Oedicerotidae) from the southeastern United States Author Foster, John M.

Gnathopod 1 , carpal lobe of medium length and width, reaching palmar angle. Pereopods 2­3 , carpus longer than propodus; propodus broad, subovate, narrowing distally; dactyl short, one third or less length of propodus. Pereopods 4­5 , merus relatively short, strongly expanded distally; dactyl short, one half or less length of propodus. Pereopod 7 , carpus slightly longer than merus, subequal to propodus in length; dactyl, posterior margin strongly setose, bearing long natatory setae. Uropods 1­3 , tips of rami not extending subequally, those of uropod 3 shorter than those of uropod 1­2 . Telson subquadrate or rounded apically. Remarks .– Because the new euryhaline species here described from southeastern U. S. estuaries appears to have its closest affinities with Ameroculodes , we here emend this genus to receive it. As species within the genus Monoculodes sensu Bousfield and Chevrier ( 1996 ) also have rounded or subquadrate epimeral plates, we consider this a specific, rather than a generic, character within the genus Ameroculodes , as well. The short dactyls of pereopods 3­6 , especially those of pereopods 3 and 4 , appear to be the best diagnostic character for the genus Ameroculodes .
