Choeradoplana abaiba is a species of land planarian belonging to the subfamily Geoplaninae. [1] It is known from specimens found in Serra do Tabuleiro State Park in Brazil.
Choeradoplana abaiba is a small flatworm that generally, when unmoving, does not reach past 4 cm in length and 4.5 mm in width. It has a slender, flattened body. The base color of its body is an ochre yellow. There are two separate populations of C. abaiba that observe slight differences in their markings. The Eastern population, within Paulo Lopes, has densely distributed brown pigment aside from irregular, round, clear areas and a slight midline. The Western population, within São Bonifácio, is covered with brown speckles on the dorsal side that form a reticulated ornament; the speckles are denser in the center of the body and looser on the margins. The ventral side is a sand-yellow color. [2]
It is distinguished from other members of Choeradoplana by its mottled brown speckles, sperm ducts that penetrate the lower-front or side-front wall of the penis bulb, a prostatic vesicle within the penis bulb with a dorsally-oriented proximal half, and no permanent penis papilla. [2]
The specific epithet of abaiba is derived from the Tupi language word abaíba, meaning "difficult, arduous". This is in reference to the reported difficulty of delimiting the species' taxonomy both morphologically and molecularly. [2]
Geoplaninae is a subfamily of land planarians endemic to the Neotropical region. Members of this family are sometimes referred to as the Neotropical land planarians. However, one species, Obama nungara has been introduced in Europe.
Luteostriata is a genus of land planarians from Brazil characterized by a yellow body with dark longitudinal stripes.
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.
