Comments. The holotype of Archiborborus edwardsi (examined in BMNH by S.A.M., 1989) is in poor shape, with only a wing and part of the thorax remaining. The original description is not detailed, but the characters in the description and what remains of the holotype only match A. hirtus among the known species of Chilean Archiborborinae . Richards (1931) describes the two species as very similar, while the differences he ascribes to them do not appear to have any significance.

The unique pattern on the frons, the simple 5 th sternite in males, and the discs on the abdominal pleuron in females separate this species from others in the genus.
