Vagina of Lipeurus lawrensis tropicalis, an ischnoceran Phthiraptera.
The vagina in poultry lice, Lipeurus lawrensis tropicalis PETERS, is a simple cup-shaped structure but is complex in its internal organization. It is divisible into anterior, central and posterior part. The anterior tubular part is deeply sunk into the posterior cup-shaped one due to the invagination of the central part. The space thus formed probably serves as sperm storage, as the spermatheca is absent.
