N.B.: described as tribe Heptatheleae, elevated to family rank by Petrunkevitch, 1939a: 149, status confirmed by Haupt, 1983: 289, synonymized with Liphistiidae by Raven, 1985a: 16; revalidated by Li, 2022: 72 (Heptathelidae include all former liphistiid genera, with exception of Liphistius) and confirmed by Kulkarni, Wood & Hormiga, 2023: 485, f. 5; Breitling, 2022a: 3 re-united both families, but this is not followed here, as he omitted younger splittings of other families (e.g. Selden & Penney, 2010: 184) and the age of splitting is no sufficient reason to re-unite the families.
