Obama anthropophila is a species of Brazilian land planarian in the subfamily Geoplaninae. It is a very common land planarian in human-disturbed environments in southern and southeastern Brazil.[1]
Obama anthropophila is a medium-sized land planarian with a lanceolate body. The largest specimens have a length of about 70 millimetres (2.8 in) or more. The dorsum varies from dark to light brown, becoming lighter towards the body margins. In some cases, the dorsum may be a greenish-brown. The ventral side is pale grey or brown and has a darker margin that is a continuation of the color of the dorsum.[1] It is very similar in appearance to the closely related Obama decidualis and Obama ladislavii, the main difference with the latter being the color.
The numerous of eyes of O. anthropophila are distributed marginally on the first millimeters of the body and posteriorly become dorsal, occupying almost the entire body width at the median third. Posteriorly they become less numerous. The dorsal eyes are surrounded by a region without pigmentation (halo), which can be visible on darker individuals through fine inspection as a set of small light dots.[1]
On fully mature specimens, two irregular rows of spots with a darker tinge may be seen on the first half of the body. Those rows are the many dorsal testicles visible through the body.
The sensory pits are simple invaginations arranged in a single row on the side of the body. The glandular margin composes two types of secretory cells, containing coarse erythrophil granules, or those that easily stain red, and xanthophil secretions, or those that easily stain yellow. Some cyanophil glands and fine granules are present as well. The pharynx is cylindrical.[1]
Etymology
The specific epithet is derived from the Greek language words άνθρωπος (ánthropos), "man", and φίλος (fílos), "loved", in reference to the man-disturbed habitats where the type specimens were discovered.
