originally named ''pygmaeus'', (i.e. a small size) by the English
entomologist

found in
Chelsea, at that time in the
county of Middlesex, England. As this name was already in use it was renamed by Henry Doubleday in 1859 with the specific name ''perpygmaeella''. Haworth originally placed the moth in the
genus,
''Tinea'' – a gnawing worm. Doubleday moved ''pygmaeus'' to the genus ''Nepticula'' – a grand daughter, the smallest member of a family (i.e. the small size of the moth) when he renamed it ''perpygmaeella''. The genus ''Stigmella'' – ″stigma″, refers to the conspicuous (or occasionally metallic) small dot or a brand
