摘　　要：记述了产于广西兴安早石炭世晚期大塘阶双切尾虫亚科的１新亚属—Ｐａｌａｄｉｎ（Ｓｉｎｏｐａｌａｄｉｎ）ｓｕｂｇｅｎ．ｎｏｖ．及其３新种：Ｐ．（Ｓ．）ｇｕｉｂｅｉｅｎｓｉｓｓｐ．ｎｏｖ，Ｐ．（Ｓ．）ｓｕｂｃｙｌｉｎｄｒｉｃｕｓｓｐ．ｎｏｖ，Ｐ．（Ｓ．）ｘｉｎｇａｎｅｎｓｉｓｓｐ．ｎｏｖ．。The trilobites described here come from the dark--grey thin to medium--bedded muddy limestone in the upper part of the Lower Carboniferous Datang Stage (Upper Visean)about 7' skin northeast of Xing'an County, Guangxi, South China, including I new subgenus and 3 new species, namely, Paladin Sinopaladin) xinganensis subgen. et sp. nov.,P.
