NCBI taxonID: 480729 [catenifer]
RDB speciesID: 12784 [catenifer]

Etymology (catenifer): From the Latin catena (chain) plus the suffix -ifer (bearing), in reference to the color pattern, and also an alliterative echo of the meaning with the type locality (Cheyne Beach). (G. Shea, pers. comm., 9 Feb 2024) 
EtymologyNamed after Dr. John Dell, former herpetologist at the Western Australian Museum, Perth, who collected the holotype of this skink.
