Cratera boja is a species of land planarian belonging to the subfamily Geoplaninae. [1] It is known from specimens found in Serra da Bocaina National Park in Brazil. [2]
Cratera boja is a flatworm around 34 mm in length and 4–4.5 mm in width. The body is elongate, with parallel margins, a rounded front tip, and a pointed back tip. The dorsal side of the body is an olive gray base color, spotted with black patches. The patches concentrate in a median band that may be divided by a thin midline. The ventral side of the body is olive gray, turning gray at the front end. [2]
Aside from its coloration and length, it is distinguished from other members of Cratera by having marginal eyes, a bell-shaped pharynx, the distal portion of the ejaculatory duct being widened to occupy around half of the penis papilla, a narrowing that separates the male and female atria, a postero-dorsally oriented penis papilla that is shorter than the male atrium, a prostatic vesicle with an inverted-U shape in a lateral view, several cyanophil cell necks that pierce the male atrium roof, a female atrium that is half the length of the male, and the lack of a common glandular ovovitelline duct. [2]
The specific epithet is derived from the Tupi language word boja, "intermediate, middle", in reference to the intermediate size of the ejaculatory duct's distal dilation. [2]
Obama is a genus of land planarians from South America. It contains several species adapted to human-disturbed environments, including the only invasive land planarian native to the Neotropical realm, Obama nungara, which has been accidentally introduced in Europe.
The reproductive system of planarians is broadly similar among different families, although the associated structures can vary in complexity.
