Type species. Cobalus gabina Godman, 1900 .

Definition. Previously included in Orthos Evans, 1955 (type species Eutychide orthos Godman, 1900 ) this taxon is in a different clade and is sister to Neoxeniades Hayward, 1938 (type species Neoxeniades musarion Hayward, 1938 ) ( Fig. 17 ). Due to its close relationship with Neoxeniades and monotypic composition, it is proposed as a subgenus. Keys to L. 15.4 in Evans (1955). Distinguished from its relatives by the following combination of characters: antennae longer than costal margin, forewing with short brands on both sides of vein CuA 2 and over vein 1A+2A; hindwing with convex outer margin, only moderately produced at tornus, but forewing in males narrower apically than in Neoxeniades ; uncus distally notched, gnathos shorter than uncus, valva twice as long as wide, terminally rounded, harpe separated from flattened ampulla by a small notch, serrated at the dorsal margin. In DNA, a combination of the following base pairs is diagnostic: aly956.3.2:G153A, aly103.11.2:A2076G, aly 1841.5.6:C285G, aly 1341.12.28:A1324G, and aly1146.51.1:A1222T.

Etymology. The name is a feminine noun in the nominative singular, last two syllables of the type species name.

Species included. Only the type species.

Parent taxon. Genus Neoxeniades Hayward, 1938 .
