“…Small size, frequent reproduction by sexual and asexual means, and a relatively short generation time lead to large numbers of P. heterocirrata in offshore sandy habitats. This study and work Hartmann-Schroder, 1965 Both species are small, tubicolous worms bearing a crown of branching radioles. Specimens of Euchone sp.…”

A comparison of benthic polychaete communities off the Sand Island Wastewater Outfall was undertaken to recognize organic enrichment indicator species for Hawaiian waters. Primary-treatment sewage is discharged off the south shore of O'ahu at 70 m depth. A historical data set spanning 9 yr for seven sites at 70 m and two recent studies at 20, 50, and 100 m depths were analyzed. Geochemical data did not support the assumption that the outfall is an important source of organic enrichment in nutrient-poor sandy sediments within oligotrophic tropical waters. Five polychaete species, however, appeared particularly sensitive, positively or negatively, to environmental conditions near the outfall. Neanthes arenaceodentata (Nereididae) and Ophryotrocha adherens (Dorvilleidae) have been dominant at sites within the outfall's zone of initial dilution (ZID). Since 1993, N arenaceodentata has virtually disappeared, and 0. adherens concurrently became abundant and continued to flourish at ZID sites. Wellknown indicators within the Capitella capitata complex (Capitellidae) were present at ZID and control (far field) sites though their ZID abundance was greater. Two sabellids, Euchone sp. Band Augeneriella dubia were inversely distributed, the smaller Euchone sp. B at far field sites and larger A. dubia within ZID stations. The former was most likely restricted to a greater proportion of fine sediment particles at two far field sites. The most abundant and widespread polychaete off O'ahu's south shore was Pionosyllis heterocirrata (Syllidae), which does not seem to represent a sensitive indicator species. Ophryotrocha adherens was the most abundant indicator species within the ZIDj P. heterocirrata was the most ubiquitous species at all sites and should always be expected in these sediments. Traditional measurements of numerical abundance, species richness, and diversity (H') have not shown a clear distinction between ZID and far field sites in annual analyses. An examination of composited data over an 11-yr period does support such a distinction. Multidimensional scaling (MDS) analyses clearly delineate different assemblages. We suggest that MDS analyses are sensitive to the community differences present near the outfall. The ZID community is clearly contained within the Environmental Protection Agency-approved ZID boundary. Because each ZID and far field site supports a diverse and coarsely similar polychaete fauna, no pollution level effects seem to be present.

“…Pettibone (1971:14) concluded that there was a single species, L. culveri distributed from North Carolina to Uruguay and in El Salvador along the Pacific coast, and this concept was followed in a key to Grand Caribbean species (Salazar-Vallejo & Jimé-nez-Cueto, 1997). Pettibone (1971) followed Hartman (1938Hartman ( , 1945 and included as junior synonyms three other species: L. pandoensis (Monro, 1937) from a freshwater stream in Uruguay, L. nota (Treadwell, 1941) from an inner brackish water lagoon in Texas, and L. brunnea (Hartmann-Schröder, 1959) from estuaries in El Salvador. Further, Pettibone (1971) provided some illustrations for her specimens and showed some differences regarding the size and development of body features such as tentacular cirri, parapodia and pharynx.…”

Abstract:The family Nereididae includes more than 500 polychaete species described worldwide, and includes species common in many benthic environments, but some other species may tolerate freshwater or can even thrive in humid substrates in tropical forests. In estuarine environments, nereidid polychaetes can be abundant and relevant as a food source for resident or migratory birds. Laeonereis culveri (Webster, 1879) is a common estuarine species found in tropical and subtropical Atlantic American shores and was described from New Jersey; its median and posterior parapodia have upper notopodial ligules usually longer than the lower ones, and the latter are parallel to the notaciculae throughout the body. L. culveri distribution is from Connecticut to central Argentina; however, this wide distribution might be due to the inclusion of several other species as junior synonyms, despite that some morphological differences were found between them. One of such species is L. nota (Treadwell, 1941), that was described from Texas; its parapodia have notopodial ligules of about the same size, and the lower ones are oblique to the notaciculae. In order to clarify the differences between these two species, and to define which inhabits the Northwestern Caribbean region, topotype materials from these two species and specimens from Chetumal Bay were collected, and their morphological features were compared. Our results indicated that L. culveri and L. nota are different species and that the latter is found in Chetumal Bay. On the basis of mature specimens, L. culveri is hereby restricted to the Northern Gulf of Mexico and Northwestern Atlantic Ocean, and L. nota is reinstated and its distribution extends from Texas, in the Gulf of Mexico to Chetumal Bay, in the Northwestern Caribbean Sea. A key to identify all species in Laeonereis Hartman (1945) is also included. Rev. Biol. Trop. 64 (1): 189-201. Epub 2016 March 01.Key words: taxonomy, Polychaeta, parapodial variations, Gulf of Mexico, Caribbean Sea, Annelida, shorebirds.The polychaete family Nereididae de Blainville, 1818 includes species common in many benthic environments and has over 700 species in 45 genera worldwide (Read, 2015;Santos, Pleijel, Lana, & Rouse, 2005) Because they have been known since Linneaus and are frequently included in invertebrate zoology texts, this family is probably one of the best known among the polychaetes. Some nereidid species occur in estuarine or freshwater environments (Glasby & Timm, 2008), usually having more species than any other polychaete family in freshwater reservoirs (Foster, 1972); some species can even thrive in humid substrates in tropical forest trees (Glasby, Kitching, & Ryan, 1990;Glasby, Mogi, & Takahashi, 2003).The morphological diagnostic features are well known for distinguishing genera among nereidids including prostomial, parapodial, chaetal and pharynx features, despite the fact that many undergo an impressive transformation of the body for reproduction (eyes become larger, and parapodia are transformed by a widening ...
