Nomenclature Sanamyan et al. (2023) proposed to synonymize the family Baeriidae Borojevic, Boury-Esnault & Vacelet, 2000 to Leuconiidae Breitfuss, 1897. However, we understand that the Zoological Code values, above all, stability and Baeriidae has been used since its proposal in 2000, while Leuconiidae is a family that has had little acceptance and use. Besides, the family names Leuconidae Sars (Crustacea) and Leuconi(i)dae Haeckel/Vosmaer/Breitfuss (Porifera, Calcarea) are in fact homonyms because the one letter difference (Zoological Code - Art. 55.4) is caused by the suffix (-idae or -iidae), whereas the genus part is nomenclaturally the same (Leucon vs. Leuconia) with the possibility to choose the stem in different ways. Family names in the early taxonomic literature often do not have the prescribed stem+idae for names published before 1900 (see Art. 11). Consequently, the WPD prefers to retain the family name Baeriidae. [details]
