Head with appressed scales. Ocellus posterior. Proboscis developed. 
Antenna moderately ciliated in male, ciliations under 1. Palpus moderate, 
porrect, slender, median segment with appressed scales, slightly roughish 
above and beneath at apex, terminal segment moderate, obtuse. Thorax 
without crest? (damaged). Fore wing without costal fold in male, without 
raised scale-tufts, lb furcate, 2 from 2 / 3 , 3 from angle, 3—5 separate, 
5 parallel, 7 and 8 stalked, 7 to termen, 9 closely approximated, 11 from 
middle. Hind wing without cubital pecten, 2 from 3 / 4 , 3 and 4 stalked, 
from angle, 5 approximated, 6 and 7 stalked. 
Typus generis Cleptacaca tryphera spec, nov., male. 
Closely allied to preceding, superficially differing only by absence of 
costal fold in fore wing, but with the male genitalia of a quite different 
type, much like those in Cnephasia Curtis (approaching the “ Nephodesme ” 
type of Pierce).
