The family Parastenocarididae Chappuis, 1940, formerly Parastenocaridae Chappuis, 1933, is still in a confused taxonomic state (Reid, 1994). At present, the family inludes five valid genera: Parastenocaris Kessler, 1913; Forficatocaris Jakobi, 1969; Paraforficatocaris Jakobi, 1972; Potamocaris Dussart, 1979 emend. Reid, 1991; Murunducaris Reid, 1994. Parastenocaris is the most prolific and widespread genus, the other genera including few species, limited to the neotropical region.
