Abstract

The DNA of Trigonopterus specimens from the Sundaland region stored between ten and 32 years in museums could be used for next-generation sequencing. The availability of their cox1 sequence allowed the description of the following nine new species: Trigonopterus grimmisp. nov., T. johorensissp. nov., T. lambirensissp. nov., T. linauensissp. nov., T. microreticulatus Riedel, Trnka & Wahab sp. nov., T. mulensissp. nov., T. sarawakensissp. nov., T. siamensissp. nov., and T. singaporensissp. nov. The alternative original spelling of the name T. tounensis Narakusumo & Riedel is chosen to prevail over T. tounaensis Narakusumo & Riedel. The new species represent the first country records of Trigonopterus for Brunei, Singapore, and Thailand. Thus, the genus´ known area of distribution in the Sundaland region is significantly extended. A key and a catalogue are provided to the Trigonopterus species from Borneo, W-Malaysia, Singapore, and Thailand.
