I hope we located first Russian passport of the Zvolaneks issued to them after their arrival in the Kiev gubernia. The 1885 registry of foreigners who received passports as residents of the Russian Empire does not list your ancestors (State archive of Kiev oblast: f.2, оp.145, file №867). For the first time, they were listed on the 1886 registry of foreigners (State archive of Kiev oblast: f.2, оp.145, file №906, p.83v). According to this registry, their passport was issued on 26 October 1886.
We succeeded in finding it (State archive of Kiev oblast: f.2, оp.115, file №347, p.70). Their Russian passport under # 3328 was issued on the basis of their Austrian passport issued in Khotebork (Russian spelling) on 30 July 1886 under #40. It lists Iogan Tsvolanek, his wife and three children (Iosiph, Eduard and Frantsishka). The passport also describes Iogan Tsvolanek's appearance.
