Obama carbayoi is a species of Brazilian land planarian in the subfamily Geoplaninae.
Description
Obama carbayoi has a broad, flat and foliaceous body. It can reach up to 141 mm in length. The dorsal color is homogeneously black, slightly paler at the anterior end. Under a stereo microscope, the background color is seen as light brown covered by dense black pigmentation. The ventral side is orange with a dark margin. The eyes surround the anterior end in a single row, and after about 2 mm from the tip the rows increase to two or three. At about 1.5 cm from the anterior end, the eyes spread onto the dorsum, forming a band of about 2.5 mm on each side and, after 5.5 cm from the anterior end, they start to become sparser.The copulatory apparatus includes a permanent penis papilla that occupies most of the male atrium.
