Juxta

Phallus and juxta in ventro-lateral view of the moth Antispila oinophylla

In insect anatomy, the juxta is an organ in the males of most Lepidoptera (i.e. moths and butterflies) that supports the aedeagus, the organ used for reproduction in insects. The juxta is located between the two valvae.[1]

The term comes from the Latin iuxta, meaning alongside. The biological use of the term should not be confused with the more general use of juxta- as a prefix.
