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. 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.

“…Seven species of Notaulax have been previously reported to Tropical America and Mexico: N. bahamensis Perkins, 1984 ( Perkins 1984 ), N. californica (Treadwell, 1906) ( Treadwell 1906 ), N. circumspiciens (Ehlers, 1887) ( Ehlers 1887 ), N. midoculi (Hoagland, 1919) ( Hoagland 1919 ), N. nudicollis (Krøyer, 1856) ( Krøyer 1856 ), N. occidentalis (Baird, 1865) ( Baird 1865 ) and N. paucoculata Perkins, 1984 ( Perkins 1984 ; Tovar-Hernández and Salazar-Vallejo 2006 ; Tovar-Hernández and Salazar-Silva 2008 ; Tovar-Hernández 2009 ; Miranda Salinas et al 2016 ; Yáñez-Rivera et al 2020 ).…”

The sabellid genera Anamobaea Krøyer, 1856 and Notaulax Tauber, 1879 are two of the most attractive polychaete worms in coral reefs. Anamobaea is represented by two Caribbean species and Notaulax with 24 species from around the world, six of them previously known to tropical America. During examination of fouling biota and sclerozoans from Mexico, Anamobaea orstedii Krøyer, 1856 was found in coral reefs from the southern Gulf of Mexico and three species of Notaulax were identified to the Mexican Pacific, two of them being new species to science. Anamobaea orstedii Krøyer, 1856 is first reported as sclerozoan of dead coral from the southern Gulf of Mexico. An amendment to the generic diagnosis of Anamobaea is provided, based on the presence of a higher number of skeletal cells than previously recorded; height, shape and exposition of the anterior peristomial ring; the non-fusion of dorsal collar margins to faecal groove; shape of collar chaetiger and abdominal chaetae and distribution and shape of radiolar ocelli. Notaulax californica (Treadwell, 1906) is reported as fouling in buoys and docks from the Gulf of California. Two new species of Notaulax are described: the former was found in hull and dock fouling from La Paz (Gulf of California) and the second one as sclerozoan of oysters from a dock fouling in Acapulco (south Mexican Pacific). In addition, reproductive features are described for the first time for A. orstedii which is a simultaneous hermaphrodite with female and males gametes found within the same segments of abdominal region. Oocytes develop synchronously and sperm morphology (spherical nucleus and rounded acrosome, four spherical mitochondria and a long free flagellum) suggest an adaptation to broadcast spawning and external fertilisation. Species of Notaulax here examined were gonochoric, with gametes distributed in abdominal segments.

“…Ese reconocimiento tiene su sustento en las 94,412 especies que han sido registradas en el territorio nacional (Martínez-Meyer et al, 2014). De ellas, 1,500 especies corresponden a un grupo de invertebrados: los anélidos poliquetos, gusanos que se distribuyen prácticamente en todos los ecosistemas bénticos marinos, donde a menudo son el componente dominante en términos de número de individuos y especies (Tovar-Hernández et al, 2014a). No obstante, los poliquetos han logrado invadir con éxito el ambiente pelágico, cuerpos de agua dulce e inclusive el medio terrestre: en el plancton 9 familias son consideradas holopláncticas exclusivas de ecosistemas pelágicos de mar abierto (Suárez-Morales et al, 2005); aproximadamente 168 de las 15,000 especies de poliquetos conocidas en el mundo son dulceacuícolas o semiterrestres y arbóreas, propias de los bosques húmedos tropicales (Glasby y Timm, 2008;Glasby et al, 2009).…”

Resumen La bahía de La Paz (golfo de California) es un sitio prioritario para su conservación, por lo que contar con una obra que documente la biodiversidad que alberga es una necesidad apremiante. El propósito de este trabajo es proporcionar un inventario actualizado de anélidos poliquetos de la bahía de La Paz, validado taxonómica y geográficamente. Se realizó una búsqueda y recopilación de literatura existente hasta el 2019 y se incluyen nuevos registros. En esta bahía se han registrado 287 especies, 156 géneros y 37 familias.
