[1] It is found in areas of Atlantic Forest within Blumenau and Serra do Tabuleiro State Park in Brazil.

The head, or cephalic region, is distinguished by a rolled up and dilated "neck" with the ventral surface facing outwards, with glandular cushions.

The dorsal side of the body is a yellow-green base color with three thin, irregular longitudinal lines made up of small black spots.

[2] It is distinguished from other members of Choeradoplana by its yellow-green color and irregular black lines, its zinc-yellow ventral side, a compact copulatory apparatus lacking a penis papilla, and a funnel-shaped female atrium.

[2] The specific epithet is presumably taken from the prefix tri- and the Latin striatus, meaning "striated", likely in reference to the three irregular lines on the species' body.
