Fenops Grishin , new subgenus

Type species. Cabares enops Godman and Salvin, 1894 .

Definition. The genomic tree reveals that the genus Polyctor Evans, 1953 (type species Pirgus [sic!] polyctor Prittwitz, 1868 ) splits into two prominent clades at the tree level of subgenera ( Fig. 4 ). A subgenus represented by one of the clades does not have a name. Species of this new subgenus key to E.18.2a in Evans (1953) and are distinguished from the relatives by the following characters: absent white bands and spots on dorsal side of wings, hindwing outer margin strongly humped or angled in the middle, terminal projection of harpe on the right valva strongly upturned and reaches costa. In DNA, a combination of the following nuclear genomic base pairs is diagnostic: aly7032.3.4:A46C, aly798.5.3:T760G, aly798.5.3:A794C, aly16.3.1:T537A, aly16.3.1:T825C.

Etymology. The name is a masculine noun in the nominative singular, a fusion of the names of the two species placed in the genus: Fe [ra]+[e] nops.

Species included. Cabares enops Godman and Salvin, 1894 , Achlyodes fera Weeks, 1901 , and Polyctor tensa Evans, 1953 .

Parent taxon. Genus Polyctor Evans, 1953 .

Polyctor (Polyctor) dagua Evans, 1953 is a species distinct from Polyctor (Polyctor) polyctor (Prittwitz, 1868)

Sequencing of the holotype of Polyctor (Polyctor) polyctor (Prittwitz, 1868) (type locality in Brazil: Rio de Janeiro) and its comparison with present-day specimens reveals distinction of Polyctor polyctor dagua Evans, 1953 (type locality Colombia: Dagua), phenotypically unique taxon in its darker aspect and yellower white bands. E.g., the Z chromosome Fst / Gmin between them is 0.39/0.00. Therefore, we propose that Polyctor (Polyctor) dagua Evans, 1953 new status, is a species distinct from Polyctor (Polyctor) polyctor (Prittwitz, 1868) .
