Obama ladislavii is a species of Brazilian land planarian in the subfamily Geoplaninae. It is one of the most common land planarians in human-disturbed environments in southern Brazil and is easily identifiable by the green color of its dorsum.[1]
Obama ladislavii is a medium-sized land planarian with a lanceolate body. The larger specimens have a length of about 100 millimeters or more. The dorsum is green, varying from luminous green to brownish green without stripes. The ventral side is yellowish.[2]
The numerous eyes, about 800, are distributed marginally on the first millimeters of the body, being visible as a group of very small black dots, and posteriorly become dorsal, occupying up to 30% of the body width on each side. The dorsal eyes themselves are not easily visible to the naked eye, but are surrounded by a zone without pigmentation, called halo, which may be perceived as small whitish dots.[2]
On fully mature specimens, two irregular rows of spots with a darker green tinge may be seen on the first half of the body. Those rows are the many dorsal testicles visible through the body.
Distribution
Obama ladislavii is known to occur in the two southernmost Brazilian states, Santa Catarina and Rio Grande do Sul. It is found in both native and disturbed environments, including seasonal and moist forests, as well as in human-disturbed areas, such as gardens, parks and plantations.[1] Among the forest formations in which it was recorded are Araucaria moist forest, Atlantic rainforest, and deciduous and semideciduous seasonal forests.[1][3]
