Description
Cratera ochra is a medium-sized land planarian with a lanceolate body, reaching up to in length. The dorsum is yellow-ochre in colour, covered with a dispersed greyish to greyish-brown pigmentation that forms two diffuse and irregular longitudinal bands, and two paramarginal longitudinal stripes that are slightly darker than the bands. The ventral side is pale-yellow.The several eyes of C. ochra are distributed marginally in the first few millimetres of the body and posteriorly become dorsal, occupying around 40% of the body width on each side at the meddle third of the body.
Aside from its colouration and dorsal eyes, C. ochra is distinguished from other members of Cratera by a glandular margin with four or more types of glands, a cylindrical pharynx, an extrabulbar prostatic vesicle with an ample, expanded proximal portion and a tubular distal portion, and ovovitelline ducts that emerge dorsally from the middle of the ovaries and ascend anterior to the gonopore.
