"Elachista" cataptila is a moth with an unclear taxonomic position. It was described by Edward Meyrick in 1897. It is found in Australia, where it has been recorded from Western Australia.[1]
The wingspan is 7–8 mm. The forewings are grey whitish, irrorated (sprinkled) with black or dark grey. There is an ill-defined blackish discal streak from the base to near the middle. The plical and second discal stigmata are black. The hindwings are grey.[2]
The species was described in the family Elachistidae, but was excluded from this family in a later study.[3]
