Type species. Pyrgus georgina Reakirt, 1868 .

Definition. A sister genus to Gorgythion Godman and Salvin, [1896] . Formerly placed in Chiomara Godman and Salvin, 1899 (type species Achlyodes mithrax Möschler, 1879 ), but are not monophyletic with the type species ( Fig. 6 ). Keys to F.13.1a or F. 13.4 in Evans (1953). Morphologically, characterized by asymmetry in male and female genitalia and distinguished from all other Erynnini general by a likely synapomorphy: corpus bursae in female genitalia with an additional sack-like compartment stemming from its distal end, separated from the corpus by a narrow neck and folded inside the abdomen to point caudad. In wing patterns, distinguished from Chiomara and Crenda gen. n. by a discal dark bar in the cell of dorsal forewing, also present in its sister Gorgythion . In DNA, a combination of the following base pairs is diagnostic: aly1264.13.9:G91T, aly595.7.8:A121C, aly525.18.1:T1397A, aly536.219.9:C2312G, aly260.4.1:G877C.

Etymology. The name is a masculine noun in the nominative singular, a fusion of Chio [mara], where these species were formerly placed, and [Gorgy] thion, near where they ended up.

Species included. The type species, Papilio asychis Stoll, [1780] , Achlyodes basigutta Plötz, 1884 , and Chiomara khalili Riley, 1934 .

Parent taxon. Subtribe Erynnina Brues and Carpenter, 1932.
