Etymology
. The name
planicauda
is a noun in apposition that combines the Latin words planus and cauda, meaning flat and tail, respectively. The name refers to the dorsoventrally flattened female cerci.
Life history.
This species forms large, hemispheroid galls up to
1 cm
in diameter that show on both sides of the leaves of
Faramea occidentalis
(
Fig. 1
). Individual galls may coalesce. Galls are inhabited by one to several larvae, each in its separate chamber. Pupation takes place in the gall. When the adult is fully formed, the pupa exits partway out of the gall from the underside of the leaf, and the adult then emerges from the pupa. Several generations occur per year.
