Aristophanes, Acharnians 273 (web address 1), with scholion. Adler also cites the lexicon of Codex Laurentianus 59.16. The headword is the Attic form of the feminine ethnic term for a person from Thrace, so an alternative translation would be "Strymodoros's Thracian woman".
cf. phi 189, where the same passage is quoted, and translated in this way. See also omicron 130, for reference to a play called *qra=|ttai ('Thracian Girls), and pi 2720, for another instance in Aristophanes (Wasps 828) where the same term/name is applied to a slave woman. Slaves were often given names reflecting their ethnic origins (for parallel instances see Wasps 433 ('Phryx': male) and 1371 ('Dardanis': female)), so deciding which translation is more appropriate is usually impossible.
