Trigonopterus allotopus is a species of flightless weevil in the genus Trigonopterus from Indonesia.[1]
The specific name is derived in Latinized form from the Greek words allos, meaning "foreign", and topos, meaning "place". The name was chosen because T. allotopus is most south-western of the T. politus species group.
The species has an ovate body measuring 2.4 mm long. General coloration is black with rust-colored antennae.
The species is found at an elevation of 1305m (4,281feet) on the island of Sumbawa in the Indonesian province of West Nusa Tenggara.
T. allotopus has been found in leaf litter, but is believed to live in foliage.
