Pachyonomastus is a monotypic genus of East African jumping spiders containing the single species, Pachyonomastus kittenbergeri.

It was first described by Lodovico di Caporiacco in 1947,[2] and is only found in Africa.

[1] The name is a combination of the Ancient Greek παχύς ("pachys"), meaning "thick", and the related genus Onomastus.

The species is named in honor of Kálmán Kittenberger, who collected the species.
