This paper identifies the Exogoninae (Syllidae) from the Mexican Caribbean coasts and includes a key to identify all the species recorded from the Grand Caribbean Sea. The classification of the family and the composition of Exogoninae are briefly examined; the correct names of the subfamilies are Syllinae Grube, 1850, Eusyllinae Malaquin, 1893, Autolytinae Malaquin, 1893 and Exogoninae Langerhans, 1879. Exogoninae includes Anguillosyllis Day, 1963, Brania de Quatrefages, 1866, Braniella Hartman, 1963, Exogone Ørsted, 1845, Exogonella Hartman, 1961, Exogonoides Day, 1963, Parapionosyllis Fauvel, 1923, Psammosyllis Westheide, 1990, Spermosyllis Claparède, 1864, and Sphaerosyllis Claparède, 1863. Pseudexogone Augener, 1922, formerly included in the group, is not a syllid; it belongs to Pilargidae. We collected 814 specimens belonging to 3 genera, 3 subgenera and 13 species as Brania (4), Exogone (4) and Sphaerosyllis (5); five new species are described: Brania russelli n. sp, Brania uebelackerae n. sp, Brania westheidei n. sp., Exogone (Exogone) bondi n. sp. and Exogone (Parexogone) sanmartini n. sp. For each species, selected references, diagnostic features, observations on morphological variability, distribution and illustrations are provided; new species also have an english diagnosis. Most abundant species were B. uebelackerae n. sp. (295), S. taylori Perkins (169), E. (E.) dispar Webster (76), and E. (E.) bondi n sp. (72).
本文鉴定了墨西哥加勒比海岸的外钩沙蚕亚科(叶须虫科),并给出了一个用于鉴定大加勒比海记录的所有物种的检索表。简要研究了叶须虫科的分类和外钩沙蚕亚科的组成;亚科的正确名称为1850年的叶须虫亚科、1893年的真叶须虫亚科、1893年的自裂虫亚科和1879年的外钩沙蚕亚科。外钩沙蚕亚科包括1963年的鳗叶须虫、1866年的布兰叶须虫、1963年的布兰叶须虫属、1845年的外钩沙蚕、1961年的外钩沙蚕属、1963年的似外钩沙蚕、1923年的副刺叶须虫、1990年的沙叶须虫、1864年的精叶须虫和1863年的球叶须虫。1922年的假外钩沙蚕以前被归入该类群,但它不是叶须虫科的;它属于毛刺虫科。我们采集了属于3个属、3个亚属和13个物种的814个标本,分别为布兰叶须虫属(4种)、外钩沙蚕属(4种)和球叶须虫属(5种);描述了5个新物种:拉塞尔布兰叶须虫新种、于贝拉克布兰叶须虫新种、韦斯特海德布兰叶须虫新种、邦迪外钩沙蚕(外钩沙蚕亚属)新种和圣马丁外钩沙蚕(副外钩沙蚕亚属)新种。为每个物种提供了选定的参考文献、诊断特征、形态变异性观察、分布和插图;新物种也有英文诊断。最丰富的物种是于贝拉克布兰叶须虫新种(295个)、泰勒球叶须虫(169个)、不等外钩沙蚕(169个)和邦迪外钩沙蚕新种(72个)。
