Nomenclature edit

The species was originally described as Stygothelphusa lopezformenti in 1991, but the genus name Stygothelphusa was discovered to be a junior homonym of Stygothelphusa Ng, 1989, and a replacement name, Villalobosus, was created in 2000.[1][3] This was also found to be a junior homonym, of the subgenus Villalobosus Holthuis, 1972 in the crayfish genus Procambarus, and so it, too, was replaced.[4] The genus is therefore currently known as Villalobosius.[4]
