Nomina significantia

[Anthony Appleyard]

Sometimes (in Latin and Greek authors of fiction, and in modern fiction literature), an author gives a character a name that describes or hints at the character's mentality or deeds. I thought that such a name is called a nomen significans; but earlier today a Google search found no uses of "nomen significans" with that meaning. Please, what is such a name correctly called?

Nomen loquens is certainly well attested.
