601387C3FFAD2555FD41FBCEFE44E66A.taxon	description	Scheloribates tubuaiensis Sellnick, 1959: location 4 (1 ex.). Distribution: Australian region, Caucasus. Galumnidae Galumna fordi (Jacot, 1934): location 2 (1 ex.). Distribution: Tropical region. New record of the species in New Caledonia. The list includes eight species, belonging to six genera and five families. Tyrphonothrus maior, Scheloribates fimbriatus whitteni, and Galumna fordi are reported in New Caledonia for the first time. Scheloribates fimbriatus whitteni is known only in the Marquesas Islands, the other species (except one new species) have broad distributions (more than one geographical region), including two semicosmopolitan species.	en	Ermilov, Sergey G., Mary, Nathalie J.
