Described from the unique type male. This species has no known 

 near relatives. 



Eudolichura, new genus 



Type-species: Eudolichura exuta, new species, by monotypy and 

 present designation. 



Antenna slightly more than half the length of forewing, simple 

 (male not known) ; scape without pecten. Labial palpus only slightly 

 curved, more than three times as long as head; second and third 

 segments about equal in length and both somewhat roughened 

 beneath but second segment without any brush. Head roughened 

 with dense scales above; ocellus present, very small, posterior; 

 tongue well developed; maxillary palpus moderate, slender, ascending. 

 Hindtibia moderately stout, smooth dorsally, roughened beneath. 

 Forewing with 12 veins, all veins separate; 2 well before angle of cell, 

 three times as far from 3 as 3 is from 4; other veins well separated; 

 accessory cell present. Hindwing with 8 veins; 2 remote from 3; 

 3 and 4 well separated; 5 and 6 stalked; 6 and 7 nearly parallel; 

 hair pencil present on base of wing. 



Female genitalia without signum. 



Eudolichura appears to have its affinities with the New Zealand 

 genera Orthenches Meyrick and Protosynaema Meyrick. Eudolichura 

 can be distinguished from Orthenches by the rough-scaled head, 

 absence of antennal pecten and the stalked condition of veins 5 and 

 6 of the hindwing. The only significant differences between Eudoli- 

 chura and Protosynaema are the stalking of veins 5 and 6 of the hind- 

 wing of Eudolichura, absent in Protosynaema, and the presence of 

 a dense clothing of scales on the basal portion of the antenna of 

 Protosynaema, absent in Eudolichura. The most nearly allied South 

 American genus appears to be Calliathla Meyrick, described from 

 Lake Nahuel Huapi, Territory Rio Negro, Argentina. This genus 

 exhibits the same venation as Eudolichura (5 and 6 of hindwing 

 stalked; not separate as characterized by Meyrick), but differs from 

 it by the presence of a well-developed antennal pecten, approximate 

 veins 9 and 10 of forewing and the very oblique discocellulars of 

 hindwing. Calliathla is also a much narrower winged genus.
