摘要
Thalassaphorura houtanensis sp. nov. from Shanghai, East China is described. It is similar to T. encarpata （Denis, 1931） in having labial palp of type A and the same pseudocelli formula on the body. It can be distinguished by the shape of unguis, chaetotaxy of labium, maxillary out lobe and ventral tube. It was confirmed as an absolutely parthenogenetic species after a reproduction test in the lab. In addition, the DNA barcoding sequences of this new species were sequenced and analyzed. The intraspecific genetic divergence is 0.18% on average and ranges from zero to 0.46%.
记述中国华东地区上海市的滨棘属1新种：后滩滨棘蚓Thalassaphorurahoutanensissp．nov．。该种与zencarpata（Denis，1931）近似，二者均具有A型下唇和相同的假眼式，但可通过爪的形状、下唇毛序、下颚须和腹管加以区分；实验室内的繁殖实验证明该种为严格孤雌生殖种类；同时，对该新种的DNA条形码序列进行了测定分析，发现该新种的种内遗传变异平均为0．18％，介于0～0．46％之间。
