Diagnosis

The frons sparsely punctate, with variable interspaces among coarse punctures, is a distinctive character for this species; on other examined Austrosphecodes the frons is densely punctate, except near antennal alveoli. 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.
