Type species: Chelonia olivacea ESCHSCHOLTZ 1829: 3 is the type species of the genus Lepidochelys FITZINGER 1843: 30.

History. Eschscholtz’s paper in Quatember contains the first description of Chelonia olivacea and thus has precedence over Eschscholtz's better known Zoologischer Atlas, and therefore is the earliest description of C. olivacea. However, Plate III of the Atlas remains the earliest illustration for what is today called Lepidochelys olivacea (Flores-Villela et al. 2016). 
EtymologyThe name Lepidochelys is formed from the Greek word lepidos (scale) and chelys (tortoise, turtle), and probably refers to the scutes covering the shell.

The name olivacea is formed from the Latin word oliva (olive tree) and refers to the characteristic olive color of this species.
