An alternative Latin plural form of acalyptrata, referring to the same taxonomic group of insects without calypters.
This is the feminine plural form in scientific Latin, used in taxonomic nomenclature for groups of organisms. The '-ae' ending is standard for Latin feminine plurals in biological nomenclature.
Scientific Latin can be confusing because it uses different plural endings like '-a' and '-ae' depending on grammatical gender—it's a remnant of when all scientific names had to follow classical Latin rules.
