Description
editCratera paraitinga is a flatworm that can reach up to 76 mm in length and 7 mm in width. The body is slightly lanceolate, with a rounded front tip. The body is widest at the pharynx, narrowing gradually towards the front and abruptly towards the back tip. The dorsal side of the body has a melon yellow median stripe that's bordered on either side by a jet black stripe; the stripes have a white band on the outside. The body margins are jet black. The front margins of the body fade into a carmine red color. The ventral side is a grey white color that fades into orange brown at the front of the body.[2]
Aside from its coloration and length, it is distinguished from other members of Cratera by having marginal eyes, a cylindrical to bell-shaped pharynx, a pharyngeal pouch 2 mm anterior to the prostatic vesicle, relatively large distal dilation of the ejaculatory duct, a penis papilla as long as the male atrium, a female atrium that is 2.4 times longer than the male, and the presence of a long common glandular ovovitelline duct.[2]
Etymology
editThe specific epithet is derived from the former name of Salesópolis, São José do Paraitinga, the type locality of the species.[2]
