Holospondyli is a proposed clade of lepospondyls from the Early Carboniferous to the Late Permian[1] that includes the aistopods, the paraphyletic nectrideans, and possibly also Adelospondyli.

[2] However, aistopods have since been recovered as stem-tetrapods more primitive than temnospondyls or other groups of lepospondyls.
