Hind wing without cubital pecten, smoothly scaled below, veins finely 
fringed with appressed rows of scales; elongate-semiovate, somewhat

Genotype: Metachorista Ursula Meyrick, 1938, female. 
A development of Schoenotenes Meyrick, characterised by neuration, 
narrow wings and small size. Mistaken by Meyrick for an Eucosmid 
genus (and placed by him in the vicinity of Herpystis).
