First described in 2013 by German coleopterologist Alexander Riedel ; Museum of Natural History Karlsruhe, Karlsruhe , Germany ), together with entomologists Katayo Sagata; Papua New Guinea Institute for Biological research (PNG-IBR), Goroka, Papua New Guinea ), Suriani Surbakti ( Suriani Surbakti ; Jurusan Biology, FMIPA-Universitas Cendrawasih, Kampus Baru, Jayapura , Papua , Indonesia ), Rene Tänzler ; Zoological State Collection , Munich ) and Michael Balke ( Michael Balke ; Michael Balke ; Maximilians-University , Munich, Germany ), which carried out an audit of the fauna of beetles of the genus Trigonopterus on the island of New Guinea [1] .
The species name T. lineatus is given on the basis of a ribbed-linear elytra sculpture (from the Latin word lineatus - linear) [1] .
