Anarsia nimbosa is a moth of the family Gelechiidae. It was described by Edward Meyrick in 1913. It is found in Namibia, South Africa and Zimbabwe.[1]
The wingspan is 11–14 mm. The forewings are dark grey irregularly sprinkled with white, and strewn with black scales tending to form streaks on the veins and sometimes a cloudy patch of dark suffusion on the fold at one-fourth. There is an elongate cloudy blackish spot on the middle of the costa and a shorter one preceding it, tending to coalesce and merge in a very undefined triangular patch of dark suffusion extending from the costa to the fold. The hindwings are grey.[2]
