Cosmocerca bengalensis sp. nov. (Ascaridida, Cosmocercidae) recovered from the rectum of an Indian bullfrog, Hoplobatrachus tigerinus (Daudin, 1803), collected from Hetampur town in Birbhum district of West Bengal, India, is described and illustrated. This species is similar to C. acanthurum, C. banyulensis, C. cruzi, C. japonica, C. kalesari, C. microhylae, C. novaeguineae, C. ornata, C. paraguayensis, C. parva, C. podicipinus and C. travassosi in having 5 pairs of plectanes supporting preanal papillae but differs from these species by general morphometry, absence of somatic papillae in females, absence of gubernaculum and having only one pair of adanal papillae in males and one pair postanal papillae in females except C. microhylae. Present parasites differ from C. microhylae by absence of gubernaculum and general morphometry. Cosmocerca bengalensis sp. nov. represents the thirtheith species assigned to the genus, seventh from Oriental region and fifth species from India.
本文描述并图示了从印度西孟加拉邦比尔布姆区赫坦布尔镇采集的一只印度牛蛙（虎纹蛙，达丁，1803年）直肠中分离出的孟加拉宇宙线虫新种（蛔目，宇宙线虫科）。该物种与棘尾宇宙线虫、巴纽勒宇宙线虫、克氏宇宙线虫、日本宇宙线虫、卡莱萨里宇宙线虫、微蹼蛙宇宙线虫、新几内亚宇宙线虫、华丽宇宙线虫、巴拉圭宇宙线虫、微小宇宙线虫、鸊鷉宇宙线虫和特拉瓦索斯宇宙线虫相似，均有5对支持肛前乳突的翼膜，但在一般形态测量、雌虫无体乳突、无引带、雄虫仅有一对肛侧乳突且雌虫仅有一对肛后乳突（微蹼蛙宇宙线虫除外）方面与这些物种不同。当前的寄生虫与微蹼蛙宇宙线虫的区别在于无引带和一般形态测量。孟加拉宇宙线虫新种是该属的第33个物种，是东方地区的第7个物种，也是印度的第5个物种。
