Ematosilinae

Could you confirm the taxonomic scope for Ematosilinae? Specifically, which higher group does it belong to (for example, order and family), or is Ematosilinae intended as a fictional or placeholder name? Some taxonomic names with similar forms have varied meanings across classifications, and I want to ensure I draft a precise, neutral wiki-style article under 300 words. Once you specify the scope, I can generate the article accordingly.
