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

[1] Luteostriata ernesti is a medium to small land planarian, reaching up to 70 millimetres (2.8 in) in length when crawling.

The dorsal color is light-yellow with five dark longitudinal stripes: one median, two paramedian and two lateral.

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

[1] The specific epithet ernesti honors the zoologist Ernst Marcus, who first described the species, but misidentified it as Geoplana marginata Schultze & Müller, 1858.
