RICCARDO PITTINO
Abstract - A revision of the genus Psammoporus Thomson, 1859 in Europe - carried out on 602 specimens - is hereby presented. The identification of the species is based on the correlation between external morphology and internal structures, i.e. male genitalia (parameres and sclerites of the endophallus) and female genital plate (styli of the ovipositor and spermatheca). The genus is present in Europe with four closely allied species: 1) Psammoporus sabuleti (Panzer, 1797), whose lectotype is hereby designated, widespread throughout North Europe; 2) P. latipunctus (Gredler, 1866), with a restricted range: N. Italy, Switzerland, Austria and S. Germany; 3) P. mimicus n. sp. (Type loc.: Switzerland, Luzern: Hasle), widespread throughout central Europe; 4) P. insularis n. sp. (Type loc.: England, Cumberland, Baron's Wood), apparently endemic to Great Britain. Bibliographic references, description, verified localities, range, illustrations of both male and female genitalia are given for each species. A key to species is included.
