Background The islands and islets of Bahía de Chamela, in the Eastern Tropical Pacific, were declared as the first marine sanctuary in Mexico and has been protected since 2002. Their marine biodiversity has been documented in a series of papers in the last decade, but only three species of polychaete worms have been reported. New information Sixteen species of sedentary polychaete worms belonging to the families Maldanidae, Oweniidae, Sabellariidae, Sabellidae and Serpulidae are reported to the Bahía de Chamela Islands Sanctuary, 15 of these species constituting the first records in the area. Isocirrus tropicus (Monro, 1928) (Monro 1928) and Notaulax californica (Treadwell, 1906) (Treadwell 1906) constitute new records to Mexico; Idanthyrsus mexicanus Kirtley, 1904 (Kirtley 1994) is first recorded since its description and one species of bamboo worm (Maldanidae) is described as new to science. The new species belongs to the genus Clymenura Verril, 1900 (Verrill 1900) and its characterised by the presence of a glandular shield on chaetiger 8; a cephalic plaque oval with smooth margins and a rounded palpode; nuchal organs straight, parallel, almost full length of plaque; manubriavicular uncini present from chaetiger 1 with 3–4 teeth above the main fang without hairs or bristles; two pre-anal achaetous segments with tori; an anal funnel with alternating triangular cirri, being the longest that are located mid-ventrally.

来自墨西哥 Bahíade Chamela 群岛保护区的管状多毛类蠕虫（Annelida），并描述了一种新的竹虫

背景 东热带太平洋的巴伊亚德查梅拉岛和小岛被宣布为墨西哥第一个海洋保护区，自 2002 年以来一直受到保护。在过去十年中，它们的海洋生物多样性已记录在一系列论文中，但仅已报道了三种多毛类蠕虫。新信息 Bahíade Chamela 群岛保护区报告了属于 Maldanidae、Oweniidae、Sabellariidae、Sabellidae 和 Serpulidae 家族的 16 种久坐不动的多毛类蠕虫，其中 15 种是该地区的第一个记录。Isocirrus tropicus (Monro, 1928) (Monro 1928) 和 Notaulax californica (Treadwell, 1906) (Treadwell 1906) 构成了墨西哥的新记录；Idanthyrsus mexicanus Kirtley, 1904 (Kirtley 1994) 自其描述以来首次被记录，一种竹虫 (Maldanidae) 被描述为科学新物种。新物种属于 Clymenura Verril 属，1900 (Verrill 1900)，其特征是在 chaetiger 8 上存在腺体；头部椭圆形斑块，边缘光滑，触角圆形；颈部器官直、平行，几乎全长斑块；从chaetiger 1 长出的爪状钩突，在主尖牙上方有3-4 颗牙齿，没有毛或刚毛；两个带花托的肛门前无节段；具有交替三角形卷曲的肛漏斗，最长，位于腹中部。1900 年（Verrill 1900），其特点是在 chaetiger 8 上存在腺体；头部椭圆形斑块，边缘光滑，触角圆形；颈部器官直、平行，几乎全长斑块；从chaetiger 1 长出的爪状钩突，在主尖牙上方有3-4 颗牙齿，没有毛或刚毛；两个带花托的肛门前无节段；具有交替三角形卷曲的肛漏斗，最长，位于腹中部。1900 年（Verrill 1900），其特点是在 chaetiger 8 上存在腺体；头部椭圆形斑块，边缘光滑，触角圆形；颈部器官直、平行，几乎全长斑块；从chaetiger 1 长出的爪状钩突，在主尖牙上方有3-4 颗牙齿，没有毛或刚毛；两个带花托的肛门前无节段；具有交替三角形卷曲的肛漏斗，最长，位于腹中部。
