Abundant and well-preserved tabulate corals of Lochkovian to Emsian (Early Devonian) age were recovered from the Fukuji Formation at the Fukuji area, Gifu Prefecture. Among them, six auloporid species are described herein : Aulopora sorayamaensis sp. nov., A.? sp. indet., Romingeria cristata sp. nov., Kanashiropora kozui gen. et sp. nov., Multithecopora? sp. indet., and Syringoporella sp. indet. Kanashiropora is proposed for a palaeofavosiporid as the second representative of the family, which was previously restricted in Wenlock (Early Silurian) of Baltica. This new genus and another genus Palaeofavosipora are distinguishable in that the septal spine may be absent, tabulae are fewer and the most mural pores situate on mid-faces of the corallites in Kanashiropora. Closely related forms with the Fukuji fauna were reported from the Hitoegane Formation, Gifu Prefecture in Japan, and Germany, Baltica and Laurentia.
