Elasmopalpus lignosellus has been considered a synonym of E. lignosellus.{{cite journal |last=Heinrich |first=Carl |author-link=Carl Heinrich |date=1956 |title=American moths of the subfamily Phycitinae |journal=Bulletin of the United States National Museum |volume=207 |pages=i–viii, 1–581 |url=https://repository.si.edu/bitstream/handle/10088/30425/1956_Bulletin_1-581.pdf }} Clarke (1965), however, re-investigated the two species and found E. angustellus to be a separate species that is confined to Chile and the Juan Fernández Islands, with material from Brazil, Argentina, Mexico and North America correctly assigned to E. lignosellus.{{cite journal |last=Clarke |first=John Frederick Gates |author-link=J.
