Trigonopterus binodulus is a species of flightless weevil in the genus Trigonopterus from Indonesia.[1]
The specific name is derived from the Latin words bi- (meaning "two") and nodulus (meaning "small swelling"). The name refers to the shape of the apex of the elytra.
Individuals measure 2.78–4.20 mm in length. General coloration is black, with rust-colored tarsi and antennae. In an example of sexual dimorphism, females carapaces are shiny, while males are dull.
The species is found around 156m–990mm (512feet–3,250feetm) in Pangandaran and on Mount Sawal, in the Indonesian province of West Java.
T. binodulus is part of the T. dimorphus species group.
