Description
Species of Amaga have a large and broad, flat body with a well-developed glandular margin, i.e., several glands discharge along the margins of the body, which can be observed in histological sections. The testes are located at the dorsum, above the parenchymal transverse muscles, while most species in the subfamily Geoplaninae have dorsal testes beneath the parenchymal transverse muscles. The copulatory apparatus lacks a permanent penis and the ovovitelline ducts enter the female atrium at the same time, without joining to form a common duct.
Etymology
The name Amaga comes from the specific epithet, amagensis, of the type-species, originally described as Geoplana amagensis due to its occurrence in the proximities of Amagá, Colombia.
