Same entry, according to Adler, in the Ambrosian Lexicon. In other lexica the plural beidioi is registered as a Laconian dialect word, for officials of some kind. Not in LSJ as that form, but see the LSJ entry on bidiai=oi (other forms bi/deoi and bi/duoi), glossed as "officers at Sparta, whose duties were connected with the charge of the the ephebi"; five in Pausanias, six in inscriptions. This is derived from *widuios, with beta representing w-. Perhaps the Suda's adjective is from the same root, with the meaning "conspicuous."
