TypesSyntype: MCZ 6430, USNM 15508 (alcoholic female, CL 203 mm); USNM 15509 (alcoholic female, CL 181 mm); USNM 15510 (adult female, skeleton, CL 206 mm, see “Reynolds et al. 2007); USNM 15511 (alcoholic female, CL 167 mm); all from Mandeville, St. Tammany Parish, Louisiana, collected by Gustave Kohn, Jun 1889.
 
CommentGraptemys oculifera flavimaculata CAGLE 1954 has been raised to full species status. However, G. flavimaculata is very closely related to F. oculifera, with G. flavimaculata having more yellow pigmentation than G. oculifera.

Diet: carnivore. 
EtymologyThe name oculifera is from the Latin oculus, eye, and the Greek phero, to bear; refers to the well-developed ocellated pattern on the pleural scutes.
