摘要

Junior homonyms of extant species, fossil Styrax laevigatus Miki 1941 (Styracaceae; non Aiton 1789) and fossil Styrax rugosus Miki 1941 (non Kurz1871), are replaced with new names respectively, S. mikii Doweld and S. plionipponicus Doweld. Lectotype specimens (based on fruits) for S. mikii Doweld and neotype (based on seeds) for S. plionipponicus Doweld are designated for the first time for fossil species.
