Eumenodora

Eumenodora Meyrick, 1906 


Eumenodora Meyrick, E. 1906. [Elachistidae]. Descriptions of Australian Tineina. Transactions of the Royal Society of South Australia 30: 33-66 [55]. Type species: Eumenodora encrypta Meyrick, 1906 by monotypy. Holotype BMNH.

Original description, Meyrick 1906
EUMENODORA n. g.
Head smooth, sidetufts spreading behind; tongue developed. Antennae ⅔, in male simple, basal joint moderate. Labial palpi moderate, curved, ascending, with appressed scales, terminal joint shorter than second, acute·. Posterior tibiae clothed with long hairs. Forewings with 2-6 parallel, 7 and 8 stalked, 7 to costa, 11 from beyond middle. Hindwings ⅔, narrow-lanceolate, cilia 2, veins 2-7 parallel.  
This would seem to be an early unspecialized type.
 Remarks: Eumenodora was found to be a member of the Xyloryctidae by Kaila, 2013 by genetic analysis.
This species has no morphological features that might be associated with the Xyloryctidae, but this is to be expected in very primitive early branches of any Gelechioid clade, which are more likely to share traits with each other that to exhibit the developed characteristics of the group.
