See Suda On Line, Pythagoras, π3124, and footnote 25: "This information suffers from a corruption in the text, arising from a misunderstanding of a source. Diogenes Laertius' passage actually reads, as the Suda does, Θεοκλείας ἀδελφῆς, but the whole remark is related to the legend of Pythagoras receiving his doctrine from a priestess in Delphi, whose name is Θεμιστόκλεια. Diogenes himself gives the correct information in a previous passage of the Life: cf. 8 παρὰ τῆς Θεμιστοκλείας τῆς ἐν Δελφοῖς."
