This epithet is based on the Greek prefix pseudo- (false) and the name of Trigonopterus allotopus Riedel, a sibling species. A noun in apposition.
Trigonopterus pseudallotopus Riedel, sp. n. was coded as “Trigonopterus sp. 945”. This species is closely related to Trigonopterus allotopus Riedel, from which it differs by ca. 5.8–6.4% p-distance of cox1 and morphologically by the weakly impressed striae 7–9 of the elytral humeri.
