Etymology: The name noronhensis is a Latinized word meaning ‘from Archipelago Fernando de Noronha’, where this species has been collected.

Remarks: Among the Neotropical species of Deinodryinus , D. noronhensis sp. nov. is close to D. diaphanus Olmi (1984) by the body totally testaceous, at most with petiole black, head granulated, without areolae or carina, notauli almost reaching posterior margin of mesoscutum. However, the new species differs from it by the following characters: head with face with little pilosity; vertex granulate, except ocellar triangle smooth (in D. diaphanus , head with vertex punctate, unsculptured among punctures); fore wing with two dark tranversal bands (in D. diaphanus fore wing hyaline); stigmal vein of fore wing with 2r-rs shorter than 3Rs&4Rs (in D. diaphanus with 2r-rs longer than 3Rs&4Rs).

Following the description of D. noronhensis sp. nov., the key to the females of the Neotropical Deinodryinus published by Olmi & Virla (2014) should be modified by replacing couplet 9 as follows:
