| Abstract: | A new species of Asterozoa, i.e., Devonaster guangxiensis sp. nov., is described from the Middle Devonian Tungkangling Formation in Xiangzhou, Guangxi. It is characterized by a very large central disk with long and straight arms, a developed inframarginal and a fat but a little sharpened mouth angle plate. By these features, it differs from the known species Devonaster eucharis (Hall) of America. |
