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 .
