The Silurian of Podolia, Ukraine, is renowned for its arthropod fauna, including eurypterids and the synziphosurine Pasternakevia. Here, we describe one of several new arthropods recently discovered in the vicinity of the Smotrych River. Smotrychaspis kurtopleurae gen. et sp. nov. is a synziphosurine euchelicerate with semicircular carapace lacking eyes, an unfused opisthosoma with 11 visible segments, the posterior tergites wide and bearing falcate epimera and a relatively long and stout telson. Smotrychaspis resembles pseudoniscid and bunodid synziphosurines but cannot be placed in either of these families.
