Early Ludlow (Late Silurian) pachyporids of tabulate corals are recognized from limestone of the lowest Suberidani Group in the Katuura area, Tokushima Prefecture. This assemblage is composed of five species including two new taxa, namely Hillaepora gionensis Niko and Adachi, 1999, Striatopora sp. cf. S. sugiyamai Niko and Adachi, 1999, Thamnopora senzaii sp. nov., T. suberidaniensis sp. nov., and pachyporid, gen. et sp. indet. Thamnopora senzaii differs from other species of the genus in having the exceptionally slender branches, the numerous mural pores, and very rare occurrence of the tabulae. Thamnopora suberidaniensis is distinctive in its thin intercorallite walls for the genus. The Suberidani coral fauna indicates close faunal relationship with that in the G3 Member of the Gionyama Formation, Miyazaki Prefecture. The comparable forms were also reported from the Kawauchi Formation, Iwate Prefecture in Japan, and southern Siberia.
