Type species. Eutychide lycortas Godman, 1900

Definition. With species previously placed in Orthos Evans, 1955 (type species Eutychide orthos Godman, 1900 ), this genus is not monophyletic with it ( Fig. 17 ). Keys to L. 15.2 in Evans (1955). Distinguished from its relatives by the following combination of characters: antennae longer than half of costal margin; palpi flattened with the last segment short and stout, conical in shape; mid-tibiae with spines; males with short brand over vein 2 and long and wide brand over vein 1 (~1/3 of anal wing margin length); tegumen with a long distal apophysis reaching the end of uncus; uncus narrowing distad, rounded at the tip; gnathos close to uncus in lateral view, arms divergent, protruding on uncus sides in lateral view; penis widens distally, as wide as tegumen in lateral view; valva with expanded ampulla, harpe separated from it by a gap, upturned, serrated at its distal margin. In DNA, a combination of the following base pairs is diagnostic: aly235.16.1:A601T, aly235.16.1:A602C, aly208.50.8:G914C, aly1405.22.5:G41A, and aly86.14.2:T4498G.

Etymology. The name is a feminine noun in the nominative singular formed from the type species name: [ly] Corta [s]. Also, it is phylogenetically near the genus Orthos and sounds similar to it.

Species included. Only the type species.

Parent taxon. Subtribe Carystina Mabille, 1878 .

Comments. Unusually patterned, Corta lycortas reminds of a small Talides sergestus (Cramer, 1775) , a more distant relative from the same subtribe, and maybe to some extent others from two different subtribes: Lerema accius (J. E. Smith, 1797) (Moncina A. Warren, 2008) and female Lon zabulon (Boisduval and Le Conte, [1837]) or Lon taxiles (W. H. Edwards, 1881) (Hesperiina Latreille, 1809). However, there is no reason to expect that this pattern would be present in yet undiscovered members of the genus Corta , new genus, therefore the wing pattern characters were not included in the diagnosis of this genus.
