What do the published descriptions say about species that only have a hobby name here?
Identification Open
Why it matters. Several pages are stubs because no description was read for this site. Their identification traits, size and range are therefore blank.
What would help. The original and modern descriptions of each species, with measured lengths and diagnostic characters, added with proper citations.
-
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.
