The genus Disparella (D. fusiformis Fedorov, 1987, by original designation) was established in Fedorov and Pereladov for distinctive fossil spiculae of sponges from North-Eastern Siberia of Cambrian age. However, Hessler, a living isopod (Crustacea: Malacostraca: Isopoda: Asellota: Desmosomatidae), preceded fossil generic name, which becomes a preoccupied later homonym. The isopod Disparella is well recognized in modern zoology and in current use, and in this connection a new generic designation is necessary for later homonymic fossil genus. To resolve homonymy, in accordance with the International Code of Zoological Nomenclature, Kuonamia nom. nov. (Type species Disparella fusiformis Fedorov, 1987) is here proposed as a replacement name for Disparella Fedorov non Hessler.
