Geobenazzia
Geobenazzia is a genus of land planarians that currently contains a single species, Geobenazzia tyrrhenica, found in Elba, Italy. Description. The anatomy of "Geobenazzia tyrrhenica" is very similar to that of "Othelosoma" species, the main difference being the presence of an adenodactyl, a finger-like glandular projection, in the copulatory apparatus. The male copulatory apparatus has a large seminal vesicle and a penis papilla, while the female organ has a seminal bursa (or bursa copulatrix) connected to the vagina by one duct. There is also a duct connecting the female genital atrium to the intestine.
