We report the first occurrence of Phragmatopoma caudata Krøyer in Mörch, 1863 in Piauí state, Brazil. This is the first record of this species in the APA Delta do Parnaíba, a national environmental protection area that comprises areas from 3 Brazilian states, Maranhão, Piauí and Ceará. This is also the northernmost and westernmost record of this species in Brazil to date, further extending by 415 km its known distribution in Brazil, and helping to fill a gap on the knowledge of its distribution in South America.

“…A single species occurs from El Salvador to Costa Rica on the Pacific Coast of Central America, while another one was described occurring on the Gulf of California, Mexico ( Jesús-Flores, Salazar-Gonzáles & Salazar-Vallejo, 2016 ; De León-González, Méndez & Navedo, 2018 ). The monospecificity of Laeonereis proposed by Pettibone (1971) has been questioned, resulting in the validation of six species that occur along the Atlantic and Pacific American coasts, namely Laeonereis culveri ( Webster, 1879 ) (North America coast; Orensanz & Gianuca, 1974 ), L. nota (Treadwell, 1941) (Central America coast; Jesús-Flores, Salazar-Gonzáles & Salazar-Vallejo, 2016 ), L. acuta (Treadwell, 1923) (South America coast; Orensanz & Gianuca, 1974 ; Santos & Lana, 2001 ; Liñero-Arana & Díaz-Díaz, 2007 ; Pamplin, Almeida & Silva-Filho, 2007 ), L. pandoensis (Monro, 1937), L. watsoni De León-González, Méndez & Navedo, 2018 (Gulf of California; De León-González, Méndez & Navedo, 2018 ), and L. brunnea (Central America Pacific coast; Dean, 2001 ; Dean, Sibaja-Cordero & Cortés, 2012 ).…”

“…To this end, soft-bottom samples were taken with shovels or sediment corers in the intertidal zone during syzygy tide. All specimens were identified morphologically and confirmed as belonging to the Laeonereis genus, according to a set of morphological characters available in the literature (Hartman, 1938;1945;Pettibone, 1971;Orensanz & Gianuca, 1974;Dean, 2001;Santos & Lana, 2001;Liñero-Arana & Díaz-Díaz, 2007;Pamplin, Almeida & Silva-Filho, 2007;Oliveira et al, 2010;Dean, Sibaja-Cordero & Cortés, 2012;Jesús-Flores, Salazar-Gonzáles & Salazar-Vallejo, 2016), as follow: sub-pyriform prostomium; pair of frontal antennae; four pairs of frontal tentacular cirri; eversible pharynx with a pair of mandibles and tufts of soft papillae within proximal and distal rings; biramous parapodia with small ventral and dorsal cirri; and pygidium with a pair of cirri. Figure S1 presents photomicrographs and illustrations of the main characters used for the genus identification.…”

The polychaete genus Laeonereis (Annelida, Nereididae) occurs over a broad geographic range and extends nearly across the entire Atlantic coast of America, from the USA to Uruguay. Despite the research efforts to clarify its diversity and systematics, mostly by morphological and ecological evidence, there is still uncertainty, mainly concerning the species Laeonereis culveri, which constitutes an old and notorious case of taxonomic ambiguity. Here, we revised the molecular diversity and distribution of Laeonereis species based on a multi-locus approach, including DNA sequence analyses of partial segments of the cytochrome c oxidase subunit I (COI), 16S rRNA, and 28S rRNA genes. We examined Laeonereis specimens collected from 26 sites along the American Atlantic coast from Massachusetts (USA) to Mar del Plata (Argentina). Although no comprehensive morphological examination was performed between different populations, the COI barcodes revealed seven highly divergent MOTUs, with a mean K2P genetic distance of 16.9% (from 6.8% to 21.9%), which was confirmed through four clustering algorithms. All MOTUs were geographically segregated, except for MOTUs 6 and 7 from southeastern Brazil, which presented partially overlapping ranges between Rio de Janeiro and São Paulo coast. Sequence data obtained from 16S rRNA and 28S rRNA markers supported the same MOTU delimitation and geographic segregation as those of COI, providing further evidence for the existence of seven deeply divergent lineages within the genus. The extent of genetic divergence between MOTUs observed in our study fits comfortably within the range reported for species of polychaetes, including Nereididae, thus providing a strong indication that they might constitute separate species. These results may therefore pave the way for integrative taxonomic studies, aiming to clarify the taxonomic status of the Laeonereis MOTUs herein reported.

“…Orensanz and Gianuca (1974) concluded that there were morphological differences between L. culveri and L. acuta, and restricted their distribution with the former extending from North Carolina to the Gulf of Mexico, and the latter from Northern Brazil to the Valdés peninsula in Argentina. Pamplin, de Almeida andda Silva-Filho (2007) recorded L. acuta in Northern Brazil, andLiñero-Arana andDíaz-Díaz (2007) recorded it for the Southern Caribbean region. Likewise, L. brunnea was recently reinstated, and its distribution restricted to Pacific estuaries along Central America (Dean, 2001).…”

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 ...
