Luteostriata graffi is a species of Brazilian land planarian in the subfamily Geoplaninae.

[1] Luteostriata graffi is a relatively small land planarian, reaching up to 50 millimetres (2.0 in) in length when crawling.

The anterior end has a slight orange tinge and the ventral side is yellowish white.

[1] The specific epithet graffi honors the zoologist Ludwig von Graff, who first described the species, but misidentified it as Geoplana marginata Schultze & Müller, 1858.

[1] Luteostrata graffi is known to occur in areas of Araucaria moist forest and Seasonal forests in the northeastern region of Rio Grande do Sul, Brazil.
