Both amphipods inhabit freshwater environments above tidal influence. However, Paracorophium chelatum has the following characters (Karaman 1979): 1) its maxilliped lacks the distinctive rows of long setae on the basal segment (present in Paracorophium angsupanichae), 2) its male gnathopod 2 palm is smooth (palm is obtuse with subrectangular distomedial elevation bearing 4 robust setae), and 3) its urosomites 1-2 are fused (urosomites 1-3 are free in Paracorophium angsupanichae).</p></div>	https://treatment.plazi.org/id/88C863BD27FEEB9FFA4B978DB3AF751F	Public Domain	No known copyright restrictions apply.
