Cratera cryptolineata is a species of land planarian found in Brazil.
Description
Cratera cryptolineata is a medium-sized land planarian with a lanceolate body, reaching about 50 millimetres (2.0 in) in length. The color of the dorsum is homogeneously dark brown with a thin median stripe occurring along the body that is only visible under the stereomicroscope. The ventral side is light brown.[1]
The several eyes of C. cryptolineata are distributed marginally in the first millimeters of the body and posteriorly become dorsal, occupying around one third of the body width.[1]
Aside from coloration, C. cryptolineata can be distinguished from other members of Cratera by the clear halos of its eyes, a cylindrical pharynx, an almost horizontal prostatic vesicle, and a conical, symmetrical penis papilla that occupies the distal portion of the female atrium.[1]
Etymology
The specific epithet cryptolineata comes from Greek κρυπτός (kryptos), hidden + Latin lineata, striped, and refers to the thin media stripe visible under the stereomicroscope.[1]
Distribution
Cratera cryptolineata is known only from the Três Barras National Forest, Santa Catarina, Brazil.[1]
