Determining what this headword means is even harder than it needed to be because the gloss appears to be faulty, or at least uninformative. The grammatical form of the rare *zugiano/s (authentically upper case? Adler's practice of capitalizing all headwords makes it impossible to say) is not that of a word equivalent with zugo/s; rather, it should be in some way connected with or defined by it. If -- and it is a big if -- zugo/s here is the constellation Libra (see LSJ s.v. zugo/n IV.b), a *Zugiano/s could be a person born under it. For this astrological sense see e.g. Basil of Caesarea, Homilies on the hexaemeron 6.6 (and ps.-Caesarius, Quaestiones et responsiones 110, quoting Basil). But note also that the epitome of the Ethnica of Stephanus of Byzantium several times, chiefly s.v. Zugoi, identifies Zugianos as an ethnic term for the Zygoi (or Zygii), an ethnic group that Strabo 11.2.1-14 (cited by Stephanus) locates in the eastern Black Sea region. [DW: to be identified, presumably, with the 'Zichoi' of the Barrington Atlas's map 84 grid E4; and the name has survived to the present day as that of the city of Sochi, Russia's largest resort city and venue of the 2014 Winter Olympics.]
