Genus Neoproxius (Usinger &Matsuda, 1959)

Neoproxius was described as a subgenus of Proxius Stål, 1873 and later given generic rank by Kormilev & Froeschner, 1987. To date it comprises 13 species, all but one (schwarzii Heidemann, 1904) of Neotropical distribution. A key for 11 species was given by Kormilev, 1982 who also described 9 of the 13 taxa. Important characters for the separation of species are primarily the presence of a deep intraocular longitudinal groove to accommodate the antennae at rest, the position of the abdominal spiracles, and the conspicuous elevated dorsal structures on the pronotum and scutellum.

Based on these characters, the following amber inclusion described below represents a new species.
