Nineteen species of the rare polychaete genus Heterospio are reported, 15 of which are new to science. The status of H. longissima Ehlers, 1874, the type-species, is reviewed. The specimens examined are from several locations in the North Atlantic Ocean, Gulf of Mexico, Caribbean Sea, off Br azil, the Indian Ocean, the Pacific Ocean off California, New Zealand, Australia, and the South China Sea. Deep-water samples from the western North Atlantic Ocean collected by the late Drs. H.L. Sanders and R.R. Hessler that were reported by Hartman as H. longissima were re-examined and referred to two new species, H. hartmanae n. sp. (abyssal depths, New England to Bermuda transect) and H. guiana n. sp. (bathyal depths off Suriname). Other materials from the Sanders/Hessler North Atlantic collections were also examined and referred to two additional species, H. canariensis n. sp. (deep water off Canary Islands) and H. southwardorum n. sp. (Bay of Biscay) as well as H. cf. reducta from off SW Ireland in bathyal depths. New collections from the North Atlantic region include additional materials of H. hartmanae n. sp. (deep water off the Mid-Atlantic and SE USA), H. aruba n. sp. (Caribbean Sea), H. bathyala n. sp. (deep water off SE USA), and H. dibranchiata n. sp. (deep water, Gulf of Mexico). Heterospio paulolanai n. sp. is from shelf depths off southeastern Brazil. Heterospio knoxi n. sp. is from the North Island of New Zealand, H. ehlersi n. sp. is from the Gulf of Thailand, in the South China Sea, H. bidentata n. sp. is described from deep water in the Coral Sea off eastern Australia, and H. alata n. sp. and H. brunei n. sp. are described from deep water off the Island of Borneo in the South China Sea. Heterospio africana n. sp. and H. antonbruunae n. sp. are described from off east Africa in the Mozambique Channel. New records and descriptions of H. catalinensis, H. indica, and H. peruana are presented. The 15 new species reported here nearly triple the number of previously known species of Heterospio, with 23 species now recognized. All known species are tabulated and compared.
报告了 19 种罕见的多毛类异齿虫属物种，其中 15 种为新物种。对模式种异齿虫长须（Ehlers，1874）的地位进行了审查。检查的标本来自北大西洋、墨西哥湾、加勒比海、巴西沿海、印度洋、加利福尼亚太平洋、新西兰、澳大利亚和中国南海的多个地点。已故的 H.L.桑德斯博士和 R.R.赫斯勒博士在北大西洋西部采集的深海样本曾被哈特曼报告为异齿虫长须，但后来被重新检查并归入两个新种，即哈特曼异齿虫（深海，新英格兰至百慕大断面）和圭亚那异齿虫（苏里南近海的浅海深度）。桑德斯/赫斯勒北大西洋采集的其他材料也被检查并归入另外两个种，即加那利群岛异齿虫（加那利群岛附近的深海）和南行异齿虫（比斯开湾），以及来自爱尔兰西南部浅海深度的异齿虫 cf. reducta。来自北大西洋地区的新采集物包括更多的哈特曼异齿虫（中大西洋和美国东南部的深海）、阿鲁巴异齿虫（加勒比海）、深海异齿虫（美国东南部的深海）和双叉异齿虫（墨西哥湾的深海）的新标本。保罗拉诺阿里异齿虫来自巴西东南沿海的大陆架深度。新西兰北岛的诺克斯异齿虫、泰国湾的埃利尔异齿虫、东澳大利亚珊瑚海的双齿异齿虫、巴布亚新几内亚的布伦海的阿拉塔异齿虫和布鲁内异齿虫都是从深海中描述的。莫桑比克海峡东非的非洲异齿虫和安东布鲁纳异齿虫是从那里采集的。还介绍了新记录和描述的异齿虫 catalinensis、H. indica 和 H. peruana。这里报告的 15 个新种使异齿虫属已知物种的数量增加了近两倍，目前共有 23 个种被识别。所有已知的物种都被制成表格并进行比较。
