Cratera ochra is a species of land planarian in the subfamily Geoplaninae. It is found in Brazil

Description

[edit]

Cratera ochra is a medium-sized land planarian with a lanceolate body, reaching up to 85 millimetres (3.3 in) in length. The color of the dorsum is yellow-ochre covered with a dispersed greyish to greyish-brown pigmentation forming two diffuse and irregular longitudinal bands and two paramarginal longitudinal stripes slightly darker than the bands. The ventral side is pale-yellow.[1]

The several eyes of C. ochra are distributed marginally in the first millimeters of the body and posteriorly become dorsal, occupying around 40% of the body width on each side at the median third of the body.[1]

Aside from its coloration 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.[1]

Etymology

[edit]

The specific epithet ochra refers to the yellow-ochre color of the animal's dorsum.[1]

Distribution

[edit]

The habitat of C. ochra includes moist forests in northeast Rio Grande do Sul, southern Brazil, as well as plantations of Araucaria angustifolia and Pinus spp.[1]
