Abstract: The New Zealand endemic genus Euglyptus Broun, 1893 (Staphylinidae: Pselaphi-
nae: Euplectitae) is revised. Eight new species are described: Euglyptus
bifurcatus sp. nov., E. boreus sp. nov., E. dunedinensis sp. nov., E.
latefossatus sp. nov., E. parvus sp. nov., E. punctatosimilis sp. nov., E.
robertensis sp. nov., and E. waimatensis sp. nov. The following new synonyms are
proposed: Euglyptus elegans Broun, 1893 = E. costifer Broun, 1893, syn. nov.;
and E. punctatus Broun, 1893 = E. iracundus (Broun, 1893), syn. nov. Lectotypes
are designated for E. abnormis Broun, 1921, E. punctatus Broun, 1893, and E.
costifer Broun, 1893. Euglyptus now comprises 15 species; all taxa are
(re)described, habitus and diagnostic characters are illustrated, and their
distribution maps are provided. We also provide an identification key for the
Euglyptus species.
