Type species. Cobalus rastaca Schaus, 1902 .

Definition. A diverse clade without obvious affinities, a weakly supported sister of the clade consisting of Moeris Godman, 1900 (type species Talides striga Geyer, 1832 ) with Viridina Grishin, 2019 (type species Lerema (?) viridis Bell, 1942 ) ( Fig. 13 ) and therefore a genus of its own. Keys to J.50.8, or J.48.8, or L. 11.9 in Evans (1955). Distinguished from its relatives by the following combination of characters: harpe narrower than valva, typically upturned as a broad hook, ampulla expanded and bulging out, uncus broad and short, arms far apart, nearly at a distance equal to their length, tegumen short, about the same as uncus in length, saccus shorter than half of vinculum, aedeagus about the same length as valva; triangular brand at the base of forewing cell CuA 1 -CuA 2 in some species; frequently with a hyaline narrow spot between forewing veins CuA 2 and CuA 1 near the base of this cell just distad from triangular brand; forewing discal cell may be with a doublet of dash-like spots; hindwing below typically with pale spot in discal cell and postdiscal semi-circle of spots in several cells near the middle of the wing, these spots may be framed with black. Due to phenotypic diversity, best diagnosed by DNA characters and a combination of the following base pairs is diagnostic: aly 2582.9.2:C40A, aly957.1.1:T3340C, aly7480.1.19:T466A, aly7480.1.19:C467G, and aly7480.1.19:G468C.

Etymology. The name is a masculine noun in the nominative singular, formed from the first syllable of Eutychide , the genus where the type species was formerly placed.

Species included. The type species, Thoon yesta Evans, 1955 , and Cobalus mubevensis Bell, 1932 .

Parent taxon. Subtribe Moncina A. Warren, 2008 .
