Geoplana mogi is a species of land planarian belonging to the subfamily Geoplaninae. It is found in areas within the Atlantic Forest in the municipalities of São Paulo and Mogi das Cruzes, Brazil.
Description.
"Geoplana mogi" is a flatworm around in length and in width. The body has parallel margins; the front tip is rounded and the back tip is pointed. The dorsal side has a medium orange-ochre band running down the middle, flanked on each side by a thin whitish stripe; the whitish stripe is bordered on the outside by a black line, which is flanked by a grey band mottled with white. A marginal black line borders the grey band. The marginal band is often hidden from plain dorsal view due to the shape of the body. The ventral side is a whitish color with blackish margins.
Aside from its coloration, it is distinguished from other members of "Geoplana" by having parenchymal muscle fibres that form a loose tube around the intestine, and the diameter of the muscular cylinder surrounding the ejaculatory duct being 1.3 times that of the duct.
Etymology.
The specific epithet, "mogi", is derived from the type locality of Mogi das Cruzes, specifically the Tupi language name of the municipality.
