The two known females have only two submarginal cells, with a vestige of 1 r-m in the holotype left fore wing. Its females have the T1 mostly impunctate and the anterior surface of the mesoscutum rugulose by crowded punctures, a combination only otherwise found in A . brasiliensis . The body length of more than 7 mm , the mesoscutum disc sparsely punctate and polished, and the scutellum homogeneously rugose easily separate A . balrog sp. nov. from A . brasiliensis . Males not known. Etymology A tall and menacing being who can shroud itself in fire, darkness, and shadow, created by J.R.R. Tolkien. The name is used as a proper noun in apposition.
