epibenthic (20 m).
Andronov (1985, p.1738-1739) points to: It has been shown that the abdomens of adult males and females of this and, probally, other species are made up of five and not, as was held earlier, four segments; the first abdominal (genital) segment in a female is separated from the second one; mobile articulation both in a female and in a male is between the first and second abdominal segments (in contradistinction to Gymnoplea and Podoplea). These and some other signs corroborate Lang's opinion (1948) that the family Platycopiidae is a valid suborder of the Copepoda, named Progymnoplea.
