Abstract:The genus Trigonopterus Fauvel, 1862 is highly diverse in Melanesia. Only one species, Trigonopterusamphoralis Marshall, 1925 was so far recorded West of Wallace’s Line (Eastern Sumatra). Based on focused field-work the fauna from Sundaland (Sumatra, Java, Bali, Palawan) and the Lesser Sunda Islands (Lombok, Sumbawa, Flores) is here revised. We redescribe Trigonopterusamphoralis Marshall and describe an additional 98 new species: Trigonopterusacuminatussp. n., Trigonopterusaeneomicanssp. n., Trigonopterusalaspurwensissp. n., Trigonopterusallopatricussp. n., Trigonopterusallotopussp. n., Trigonopterusangulicollissp. n., Trigonopterusargopurensissp. n., Trigonopterusarjunensissp. n., Trigonopterusaspersp. n., Trigonopterusattenboroughisp. n., Trigonopterusbaliensissp. n., Trigonopterusbatukarensissp. n., Trigonopterusbawangensissp. n., Trigonopterusbinodulussp. n., Trigonopterusbornensissp. n., Trigonopteruscahyoisp. n., Trigonopteruscostipennissp. n., Trigonopteruscuprescenssp. n., Trigonopteruscupreussp. n., Trigonopterusdacrycarpisp. n., Trigonopterusdelapansp. n., Trigonopterusdentipessp. n., Trigonopterusdiengensissp. n., Trigonopterusdimorphussp. n., Trigonopterusdisruptussp. n., Trigonopterusduasp. n., Trigonopterusduabelassp. n., Trigonopterusechinatussp. n., Trigonopterusempatsp. n., Trigonopterusenamsp. n., Trigonopterusfissitarsissp. n., Trigonopterusflorensissp. n., Trigonopterusfoveatussp. n., Trigonopterusfulgidussp. n., Trigonopterusgedensissp. n., Trigonopterushalimunensissp. n., Trigonopterushonjensissp. n., Trigonopterusijensissp. n., Trigonopterusjavensissp. n., Trigonopteruskalimantanensissp. n., Trigonopteruskintamanensissp. n., Trigonopterusklatakanensissp. n., Trigonopteruslampungensissp. n., Trigonopteruslatipessp. n., Trigonopteruslimasp. n., Trigonopteruslombokensissp. n., Trigonopterusmerubetirensissp. n., Trigonopterusmesehensissp. n., Trigonopterusmicanssp. n., Trigonopterusmisellussp. n., Trigonopteruspalawanensissp. n., Trigonopteruspangandaranensissp. n., Trigonopterusparaflorensissp. n., Trigonopteruspararugosussp. n., Trigonopterusparasumbawensissp. n., Trigonopteruspauxillussp. n., Trigonopteruspayungensissp. n., Trigonopterusporcatussp. n., Trigonopteruspseudoflorensissp. n., Trigonopteruspseudosumbawensissp. n., Trigonopteruspunctatoseriatussp. n., Trigonopterusranakensissp. n., Trigonopterusrelictussp. n., Trigonopterusrinjaniensissp. n., Trigonopterusroensissp. n., Trigonopterusrugosostriatussp. n., Trigonopterusrugosussp. n., Trigonopterusrutengensissp. n., Trigonopterussaltatorsp. n., Trigonopterussantubongensissp. n., Trigonopterussasaksp. n., Trigonopterussatusp. n., Trigonopterusschulzisp. n., Trigonopterussebelassp. n., Trigonopterussembilansp. n., Trigonopterussepuluhsp. n., Trigonopterusseriatussp. n., Trigonopterusserratifemursp. n., Trigonopterussetifersp. n., Trigonopterussilvestrissp. n., Trigonopterussingkawangensissp. n., Trigonopterussingularissp. n., Trigonopterussinuatussp. n., Trigonopterussqualidussp. n., Trigonopterussumatrensissp. n., Trigonopterussumbawensissp. n., Trigonopterussundaicussp. n., Trigonopterussuturalissp. n., Trigonopterussyarbissp. n., Trigonopterustelagensissp. n., Trigonopterustepalensissp. n., Trigonopterustigasp. n., Trigonopterustrigonopterussp. n., Trigonopterustujuhsp. n., Trigonopterusujungkulonensissp. n., Trigonopterusvariolosussp. n., Trigonopterusvulcanicussp. n., Trigonopteruswallaceisp. n.. All new species are authored by the taxonomist-in-charge, Alexander Riedel. Most species belong to the litter fauna of primary wet evergreen forests. This habitat has become highly fragmented in the study area and many of its remnants harbor endemic species. Conservation measures should be intensified, especially in smaller and less famous sites to minimize the number of species threatened by extinction.
