retstra fu'ivla

x1 is a tuatara [reptile genus Sphenodon] of species/variety x2.

For disambiguation purposes, strictly, this word should only apply to members of genus Sphenodon; however, all extant members of reptile order Rhynchocephalia belong to this genus and some semantic broadening is probable. See also: respa, reksamata.

x1 is a squamate (reptile of order Squamata), of subtaxon/type/variety/species x2
