Genus Grelliella	[Grel.li.el'la] N.L. fem. dim. n. Grelliella, named after Karl G. Grell who rediscovered the placozoans	Boscaro **et al., 2019: Ca. Bandiella numerosa proposed; 16S rRNA gene sequence provided (accession LR585349.1). Gruber-Vodicka et al., 2019: Ca. Grellia incantans proposed; raw reads provided. Note: assembled genome is not available in Genbank/EMBL/DDBJ (as of October 2026) and thus is ineligible to serve as a type genome under the SeqCode. Oren & Garrity, 2021: Ca.
