Abstract
Fiji is an archipelago in the South Pacific Ocean from which only four species in four genera of Tetrigidae had previously been reported. We report the results of our examination of the Fijian Tetrigidae from the Queensland Museum, Brisbane, and additionally the Nederlands Centrum voor Biodiversiteit (Naturalis Biodiversity Center, formerly Nationaal Natuurhistorisch Museum Naturalis), Leiden. The Fijian fauna is found to be similar to, and therefore likely derived from, the New Guinean fauna. The validity of Asian Metrodorinae is called into question. The following new taxa are described: tribe Exanimini trib. nov. including genera Exanimus gen. nov. (including E. somniator sp. nov. and E. torviscriba sp. nov.) and Fijixistra gen. nov. (including F. abbreviata (Bolívar, 1887) comb. nov. of Amphinotus abbreviatus, F. drobnaki sp. nov., F. teo sp. nov., and F. tvrtkovici sp. nov.); tribe Fijitettigini trib. nov. including genera Fijitettix gen. nov. (including F. godeffroyi (Günther, 1939), comb. nov. of Salomonotettix godeffroyi) and Salomonotettix Günther, 1939 (including S. vincekae sp. nov.); genus Gammonotus gen. nov. including Gammonotus draudrau sp. nov. Exanimini trib. nov. and Fijitettigini trib. nov. are of uncertain taxonomic placement, Gammonotus gen. nov. is assigned to Cladonotini Bolívar, 1887, and Thyrsus tiaratus Bolívar, 1887 is transferred from Cleostratini Bolívar, 1887 to Clinophaestini Storozhenko, 2013.
