Different readings are attested for the headword in Photius (dusba/rkanos, obelized by Theodoridis) and the Etymologicum Magnum (dusba/rnakos), probably by corruption in the manuscript transmission.
Nonetheless it seems that the gloss stems from Photius, Lexicon delta799. (The Suda compiler either had an uncorrupted manuscript or was able to identify the error.) Hesychius delta2539 has a similar (not identical) gloss; and see further, next note.
1In Hesychius this synonym is recorded in the final part of the gloss and related to the comic poet Cratinus (fr. 404 Kock, now 442 K.-A.).↩
