and the sclerotized and setose posterior margin of the male seventh tergite, diagnostic characters of the tribe.
These two genera, however, have evenly curved ovipositors
. In Paraplangia, the fore femora are also unarmed [a character occasionally found within otherwise armed genera: e.g.

During the spawning season, females develop a long ovipositor
that they use to lay eggs in the gill cavities of mussels through the mussel's exhalant siphon.
