Abstract
In this work, several species of Eumolpinae from Vanuatu and the Solomon Islands arerevised, most belonging to the tribe Typophorini, and patterns of shared species between
these archipelagos and Fiji are highlighted. The analysis of these species results in the
proposition of several taxonomic acts, including the description of Eurydemus trispilus sp.
nov., the synonymy of Dematochroma antipodumoides Jolivet, Verma and Mille, 2010 = D.
soldatii Jolivet, Verma and Mille, 2010 syn. nov., the new combination Rhyparidella
buxtoni (Bryant, 1936) comb. nov. from Rhyparida Baly, 1861, and the proposition of
transferring Fijian and Vanuatuan Demotina Baly, 1863 to the genus Parademotina
Gressitt, 1957 comb. nov., and this genus from Adoxini to Typophorini. The male
genitalia and the spermatheca of eleven species are described, in most cases, for the first
time, and a provisional generic key of the Eumolpinae from the Solomon Islands and
Vanuatu is presented.
