本文对发现于厦门大学海滩潮间带泥基质区两种联体线虫科(Comesomatidae Filipjev,1918)的虫种进行了描述.异毛联体线虫新种(Paracomesoma xiamenense sp.nov.)由于其第二圈感觉毛的长度相同,并且比第三圈头感觉毛短;交合刺两根不等长并有两列、每列28~30个肛前乳突以及肛后的柄状乳突等特征使得该种成为一个新种.变异毛咽线虫(Dorylaimopsis variabilis Vincx,1997)的侧边分化的纵列刻痕;弓形的交合刺、突出的背尾侧骨突和14个肛前乳突等特征同Vincx(1997)的描述相近,但某些测量的数值有差别.本文并给出了异毛联体线虫属新的双歧式检索表.
本文對髮現于廈門大學海灘潮間帶泥基質區兩種聯體線蟲科(Comesomatidae Filipjev,1918)的蟲種進行瞭描述.異毛聯體線蟲新種(Paracomesoma xiamenense sp.nov.)由于其第二圈感覺毛的長度相同,併且比第三圈頭感覺毛短;交閤刺兩根不等長併有兩列、每列28~30箇肛前乳突以及肛後的柄狀乳突等特徵使得該種成為一箇新種.變異毛嚥線蟲(Dorylaimopsis variabilis Vincx,1997)的側邊分化的縱列刻痕;弓形的交閤刺、突齣的揹尾側骨突和14箇肛前乳突等特徵同Vincx(1997)的描述相近,但某些測量的數值有差彆.本文併給齣瞭異毛聯體線蟲屬新的雙歧式檢索錶.

Two species of famlily Comesomatidae from the intertidal muddy flat of the Xiamen University were described. Dorylaimopsis variabilis is the same to which M.Vincx described in its lateral punctation, bow-like spicules, dorsal-tail directed apophyses and 14 precloacal supplements. Paracomesoma xiamenense sp. nov. is identified as a new one which characters are as follows:cuticle punctuation with no lateral region difference;6 short labial setae,6 short and 4 long cephalic setae are in three separate crown;spiral amphid is about 3 circles;long oral cavity with 3 small teeth on the anterior region; cardial and its opening is obvious;2 outstretched testes in the male,slightness spicules not equal in length with obvious velum;2 lines of precloacal supplements; each about 28~30 in the form of small dilations, 2 columns, each with 3 small dilations in the post-cloacal region;2 outstretched ovaries in the female; tail conical-round.Key to the genus Paracomesoma is given.
