Established by Farran upon specimens from the north temperate and 
tropical Atlantic and not found in any of the plankton lists. In 
Steuer’s revision of the genus Plewromamma (1982, p. 84), P. piseki is 
not admitted as a separate species but is made a variety of gracilis. 
However, the genital segment is indented on the left side, there is a 
large pigmented area around the genital pore, and the fifth legs show 
differences in both sexes.
