Description
Specimen of C. nigrimarginata showing both dorsal and ventral sides.

Cratera nigrimarginata is a medium-sized land planarian with an elongate and flat body, with parallel margins, reaching about 60 millimetres (2.4 in) in length. The dorsum has a light-brownish color forming a broad band and is bordered by greyish or black margins. The venter is pale yellow.[1]

The several eyes of C. nigrimarginata are distributed marginally in the first millimeters of the body and posteriorly become dorsal, occupying almost the whole dorsal surface on the anterior third of the body, becoming less numerous towards the anterior tip.[1]

Etymology

The specific epithet nigrimarginata comes from Latin niger, black + marginata, bordered, thus meaning "black-bordered" and refers to the black margins of the body.[1]

Distribution

Cratera nigrimarginata is known only a private reserve, the Araucaria Natural Heritage Private Reserve, in the municipality of General Carneiro, Paraná, Brazil.[1]
