This new genus is named Laevispinereis. Its brief characters are as follows: oral ring of proboscis has papillae, maxillary ring has conical paragnaths; the peristomium greatly expands into a collar; notosetaes are homogomph spinigers, neurosetaes are homogomph spinigers and homogomph falcigers; tip of spinigers setae with minute serratures and smooth on side. The type of genus is Laevispinereis fujianensis sp. nov., it has conical paragnaths on maxillary ring of proboscis: I has Ⅰ; Ⅱ has 6-7: Ⅲ has 12;Ⅳ has 6-7.展开更多
