The genus currently includes a single species, Desulfurispira natronophila, including the type strain AHT11T and a second strain AHT19 (Sorokin and Muyzer, 2010a). DNA G+C content (mol%): 49.2–51.8 (Tm). Type species: Desulfurispiria natronophila Sorokin and Muyzer 2010b, 2509VP (Effectively published: Sorokin and Muyzer, 2010a, 354).
