Etymology: Phractura: Greek, phraktos = fence (Ref. 45335).
Eponymy: Claus Herluf Stenholt Clausen (1921–2002) was a California-born Danish ichthyologist and biologist. He collected in Liberia (1965). He wrote: Tropical Old World Cyprinodonts (1967). He collected the holotype. (Ref. 128868), visit book page.
