Type locality: “Africa”. Restricted by lectotype designation at “ Niger River drainage in west Africa” by Webb (1975) . Cyclanorbis elegans ( Gray, 1869 ) : Boulenger 1889: 272 . Cyclanorbis oligotylus Siebenrock, 1902: 465 . Type locality: “ Ägypten ”. Distribution . It has a wide but patchy distribution and is currently known from Ghana , Togo , Nigeria , Cameroon , Chad , Central African Republic , Sudan , South Sudan and Ethiopia ( Mazuch et al. 2016 ; Rhodin et al. 2017 ). The presence of this species in Equatorial Guinea has been overlooked ( Map 3A ). Comments. The examined specimen (EBD 31388) stands out by its large size, exhibiting a carapace length of 51 cm . There are no previous records of this genus in Equatorial Guinea ( Mazuch et al. 2016 ; Rhodin et al. 2017 ). This newly recorded population of C. elegans in Río Campo (North of Río Muni ) represents the southernmost record for the genus. The label of the examined specimen indicates that it contained in its stomach dates of nipa palm ( Nypa fruticans ) with unidentified crabs, snails, and mud. Specimens examined. One specimen. Río Muni : Yengüe , Ntem River , 21 February 1988 ( EBD 31388) .
