What the name stands for

Which *Willowsia* species are the hobby cultures?
Identification Needs a specialist
Why it matters. Animals filed under Willowsia nigromaculata in North America may be Willowsia neonigromaculata, a species split off in 2021. Hobby lists name Willowsia buski and Willowsia neonigromaculata.
What would help. Slide-mounted adults compared with the 2021 description, in particular the inner appendages on the maxillary sublobal plate, and a COI barcode.

Which species is this culture, checked by a specialist?
Identification Needs a voucher specimen
Why it matters. Hobby cultures are mostly named from a seller's label or a photograph. A wrong name spreads from seller to keeper and then into care advice.
What would help. Preserved vouchers from the culture in 80 to 95 percent ethanol, mounted specimens examined by a springtail specialist, and a DNA barcode where a reference exists. Deposit the voucher with a museum or a university collection.
