Abstract
A new find of the rare lichid trilobite Holoubkovia klouceki (Růžička, 1926) brings the first unambigous evidence of the presence of this species in the Mílina Formation (Tremadocian). So far, the species has been known from the older Třenice Formation and two lichid hypostomes formerly established from the Mílina Formation could not been well compared with specimens from the Třenice Formation. The incomplete pygidium probably belongs to early holaspid specimen.
