T. permutus nom. n. is proposed for preoccupied specific name, Trimerus lobatus Tomczykowa, 1975, Silurian trilobite of Poland. The name Homalonotus lobatus introduced by Prouty (1923) for trilobite from Silurian of Maryland, appeared to be a junior synonym of Trimerus delphinocephalus Green, 1832, as the name for juvenile stages.
