The type species of the pseudoscorpion genus Geogarypus Chamberlin, 1930, Geogarypus minor (L. Koch, 1873), is redescribed from the newly designated female lectotype and numerous specimens from southern France, Corsica and Italy. Geogarypus nigrimanus (Simon, 1879) is newly designated as a junior subjective synonym of G. minor, and a new species, G. italicus sp. nov. (type locality Bergeggi, Western Liguria, Italy), is described from specimens from mainland Italy, Sicily and Sardinia. A key to the Mediterraneo-Macaronesian species of the genus is proposed.

Protura are known all over the world with more than 800 described species belonging to three different orders (Acerentomata, Sinentomata, and Eosentomata) and seven families (Hesperentomidae, Protentomidae, Acerentomidae, Fujientomidae, Sinentomidae, Eosentomidae, and Antelientomidae). At present 76 genera are known worldwide. In this paper a description of the diagnostic characters of these genera and an updated key for their identification are reported.

A new species of Protura, Acerentulus tortii sp. nov., from the island of Euboea, central Greece, is described and illustrated. The new species belongs to the A. cunhai species group, based on a short foretarsal sensillum a not reaching seta γ3, and sensilla b and c subequal in length. The most similar species are A. christensoni (Ewing, 1940) and A. rafalskii Szeptycki, 1979), from which A. tortii sp. nov. differs by the porotaxy of sternite III and the lengths of various foretarsal sensilla.
