Type species. Antigonus obliqua Plötz, 1884 .

Definition. A likely sister genus to Potamanaxas Lindsey, 1925 , and thus not monophyletic with Anastrus Hübner, [1824] (type species Anastrus obscurus Hübner, [1824] ), where these species were formerly placed ( Fig. 6 ). The need for this genus has been suggested previously ( Austin 1998). Keys to F.6.3. in Evans (1953). Genitalia illustrated by Grishin in his fig. 30–39 ( Grishin 2012). Morphologically, distinguished from Anastrus and Echelatus by having processes on sacculus of the valva and a second pair of uncus arms, from the ventral side of uncus, similar to some species of its sister Potamanaxas , but uncus itself is essentially undivided with arms reduced to small knobs. Primary uncus arms are well-developed in Potamanaxas . In facies, characterized by brown wings above with several dark-brown stripes and often with some bluish scaling between the stripes. Below, wings plain brown and some species with slate overscaling on the posterior third of hindwing. In DNA, a combination of the following base pairs is diagnostic: aly3570.7.4:A85T, aly3570.7.4:G86C, aly9673.2.5:T298A, aly 1735.8.1:C820C (not T), aly16.28.2:C88C (not A), aly16.28.2:A89A (not T).

Etymology. The name is a masculine noun in the nominative singular, a group of species that were formerly placed in Ana [strus], but are phylogenetically closer to [Potamana] xas.

Species included. The type species, its sister Anastrus isidro Grishin, 2012 and Pellicia petius Möschler, 1877 .

Parent taxon. Subtribe Erynnina Brues and Carpenter, 1932.
