Abstract
The family Caldisphaeraceae, represented by a sole genus Caldisphaera, is a member of the order Acidilobales, class Thermoprotei. The genus houses a single validated species C. lagunensis: however, a non-validated species “C. draconis” is also described. Both are extremely thermophilic, but not hyperthermophilic, acidophilic, heterotrophic, anaerobic, coccoid archaea. They dwell in acidic terrestrial hot springs. Phylogenetically, the family is distantly related to members of the neighbor family, Acidilobaceae, whose members are all hyperthermophilic.
