| 摘 要： | 根据在中国近海采集到的标本,描述多毛类环节动物一新种——中华竹节虫（Sabaco sinicus sp.nov.）。该物种标本在乌沙科夫等（1962）报道后一直被错误鉴定为钩齿短脊虫（Asychis gangeticus Fauvel,1932）。我们基于以下性状将该种描述为一新物种：项沟和前三个刚节具深棕色色素点;刚节4–6的腺体分布特征;肛前节无刚毛;肛漏斗喇叭状,背侧小叶呈扁盘状;具膝状的背刚毛、表面有或无螺旋刺毛带的细毛状背刚毛;腹刚毛为排成一列的鸟嘴状齿片刚毛。钩齿短脊虫和该新种的区别在于前者身体无色素点,肛板背侧小叶呈三角形。自1950s以来,该物种的分布区已经从长江口以南海区明显向北扩展。

| Abstract: | Sabaco sinicus sp. nov. is described based on material collected from Chinese coast. It has been misidentified as Asychis gangeticus Fauvel, 1932 since Uschakov and Wu (1962). Here, we recognized it as a new species based on combination of the following characters: dark-brown pigmentation spots on nuchal grooves and first three chaetigers; glandular pattern on chaetigers 4–6; preanal achaetigerous segments absent; anal plaque trumpetshaped with a disc-shaped dorsal lobe; notochaetae consisting of geniculate capillaries and fine capillaries with or without spinose spiral bands; neurochaetae presented as a single row of rostrate uncini. Asychis gangeticus differ from the new species in having no pigmentations on body and a triangular dorsal lobe of anal plaque. Distribution region of this species have moved northward significantly from sea area south of Changjiang Estuary since the 1950s. |
