Review of Composetia Hartmann-Schröder, 1985 (Annelida: Nereididae), with the establishment of two new similar genera

Article

Oct 2021

Composetia Hartmann-Schröder, 1985 (Nereididae de Blainville, 1818), to which 51 species with broadly heterogeneous characteristics were previously assigned, is reviewed based upon the examination of the type material of the type species, C. costae (Grube, 1840), and seven other species. According to our designation of the lectotype of C. costae, a generic definition of Composetia is established, and taxonomic issues about C. costae are addressed. The current taxonomic status of several species similar to or previously synonymised with C. costae is re-evaluated. Based on the redefinition of Composetia, the taxonomic status of all species previously regarded as Composetia is reassessed. Consequently, three species are moved to two newly established genera based on their type material: Parasetia gen. nov., comprising the single species P. irritabilis (Webster, 1879) comb. nov.; and Potamonereis gen. nov., embracing P. kumensis (Sato, 2020) comb. nov. and P. tokashikiensis (Sato, 2020) comb. nov. Additionally, one species is redescribed and transferred to Leonnates, L. microcephala (Grube, 1878) comb. nov. Ten species currently remain in Composetia, and two of them, C. brasiliensis (McIntosh, 1885) and C. versipedata (Ehlers, 1887), are redescribed. Nereis articulata Ehlers, 1887, previously considered a member of Composetia, has a doubtful identity requiring further investigation. Although the generic placement of many of the remaining species is uncertain, we present our tentative re-evaluations for each of them. Keys are included for identifying all genera similar to Composetia, and for identifying all species within Composetia and Potamonereis gen. nov.

Redescriptions of Nereis Oligohalina (Rioja, 1946) and N. Garwoodi González-Escalante & Salazar-Vallejo, 2003 and description of N. confusa sp. n. (Annelida, Nereididae)

Article

Aug 2015

Type material of several polychaete species described by Enrique Rioja from Mexican coasts are lost, and the current status of some species is doubtful. Nereis oligohalina (Rioja, 1946) was described from the Gulf of Mexico, but it has been considered a junior synonym of Nereis occidentalis Hartman, 1945, or regarded as a distinct species with an amphiamerican distribution. On the other hand, Nereis garwoodi González-Escalante & Salazar-Vallejo, 2003, described from Chetumal Bay, Caribbean coasts, could be confused with Nereis oligohalina. In order to clarify these uncertainties, Nereis oligohalina is redescribed based on specimens from the Mexican Gulf of Mexico, including a proposed neotype; further, Nereis garwoodi is redescribed including the selection of lectotype and paralectotypes, and Nereis confusa sp. n. is described with material from the Gulf of California. A key for the identification of similar species and some comments about speciation in nereidid polychaetes are also included.

Currently, there are four recorded species of Ceratonereis Kinberg, 1865 in the Caribbean Sea; three of them are regarded as amphiamerican or widespread. This review intends to improve the current knowledge of these Ceratonereis species; descriptions and illustrations are presented based on type and additional material, including new records. After the examination of type material, the synonymy of Ceratonereis gracilis (Webster, 1884) with C. mirabilis Kinberg, 1865 is rejected, and C. gracilis is reinstated. Ceratonereis maya n. sp. is described based on records of C. excisa Grube Mller in Grube, 1873 and C. singularis Treadwell, 1929, and C. nancyae n. sp. is described based on records of C. mirabilis, from the Caribbean Sea. The examination of the type material of Nereis singularis Treadwell, 1943 showed it is not a species of Ceratonereis but belongs in Platynereis Kinberg, 1865, and the new combination Platynereis singularis is proposed. The epitokal morphology of the available specimens is described and discussed. Epitokes of Ceratonereis show more than one epitokal pattern, raising questions about the use of epitokal morphology to define genera or species. An annotated key for American Ceratonereis species is also included.

Revision of the species confused with "Nereis falsa" de Quatrefages, 1866 (Annelida, Nereididae)

Preprint

Nov 2021

Nereis falsa de Quatrefages, 1866 has been regarded as a cosmopolitan species, and several species described from different localities have been regarded as junior synonyms of N. falsa. The present study is an attempt to resolve the taxonomic confusion in N. falsa, which seems to contain several distinct species due to previous inappropriate synonymy, widely distributed in the Atlantic and eastern Pacific Oceans. For this purpose, the authors first propose the resurrection of the synonymy of N. falsa with Hediste diversicolor that was concluded during the 19th century but disregarded later. After the fixation of the identity of N. falsa sensu stricto, the authors re-evaluate the proper taxonomic status of species which have previously been confused with N. falsa. Type, topotype and non-type specimens were examined; most species are redescribed, and others are reinstated. Nereis splendida Grube, 1840 is a valid Mediterranean species, and a neotype is proposed; it includes the Mediterranean populations of what is currently regarded as N. falsa. Consequently, N. falsa is transferred to Hediste Malmgren, 1867, and some taxonomic comments are added for the latter genus and a key to species is also included. Nereis callaona Grube & Kröyer in Grube, 1857, N. marginata Grube & Örsted in Grube, 1857 and N. riisei Grube & Örsted in Grube, 1857 are restricted to tropical American shores and are all redescribed. Nereis pelagica lunulata Ehlers, 1901, formerly regarded as a junior synonym of N. falsa by Fauvel (1941), is redescribed and elevated in rank to species level. Nereis lucipeta Ehlers, 1908, formerly regarded as a junior synonym of N. splendida by Ehlers (1913) and of N. falsa by Fauvel (1919), is reinstated. Nereis occidentalis Hartman, 1945 is also redescribed. Furthermore, N. ambigua Treadwell, 1937, formerly regarded as a junior synonym of N. riisei by Monro (1933), deserves to be reinstated. Western Africa specimens recorded as N. falsa are newly described as N. mezianei sp. nov.

Reproductive morphology and redescriptions of some Neanthes Kinberg, 1865 (Annelida: Nereididae) species from the southeastern Asian seas, with comparative synoptic tables of accepted species

Article

Apr 2021

Neanthes Kinberg, 1865 is a speciose nereidid genus with some species exhibiting epitoky during the timing of reproduction. The epitokal morphology of males and females has long been agreed to be diagnostic to distinguish species. In the present study, we provide redescriptions of the type material and reassess the current taxonomic status of four Neanthes species originally described based on the reproductive forms of specimens collected from Southeast Asia: Neanthes augeneri (Gravier & Dantan, 1934), N. gisserana (Horst, 1924), N. trifasciata (Grube, 1878) and N. trifasciata vandersandei (Horst, 1924). The non-metamorphosed and epitokous diagnostic features, including new characters found in this study, were used to redescribe and distinguish these species from other congeners. The four species are here recognised in Neanthes, whereby N. vandersandei is elevated to species level. Neanthes gisserana is considered distinct from its previous senior synonym N. rubicunda (Ehlers, 1868). Morphology of both N. trifasciata and N. vandersandei, originally described based on mixed species, is restricted. Additionally, some remarks on the status of N. thysanota (Ehlers, 1908) are given. Distributional and reproductive data of the reviewed species are provided. An updated checklist of 80 valid species in Neanthes and synoptic tables of diagnostic features including the atokous and epitokous morphology are also presented.

Associated fauna in a mesophotic rhodolith bed in the Campos Basin, Brazil, southwestern Atlantic

Article

Apr 2024

Rhodolith beds are predominantly formed by calcareous red algae with a rich benthic fauna. Nonetheless, little is known about the biota relationships with their structural variability. Rhodolith shape, size and vitality were examined from 22 sampling stations in dense and sparse areas of a mesophotic rhodolith bed in the Campos Basin, Brazil located within a major oil production area. Nine taxonomic benthic faunal groups were identified: Mollusca (58 taxa), Polychaeta (51), Echinodermata (27), Crustacea (24), Bryozoa (20), Porifera (19), Cnidaria (6), Ascidiacea (2) and Brachiopoda (1). Cnidaria, Mollusca, Bryozoa and Brachiopoda were abundant in areas with gravelly/rhodolith bottoms, while Polychaeta were associated with sandy/muddy bottoms. The faunal composition in the Peregrino oil field showed greater species richness than observed in other rhodolith beds worldwide. The present study contributes to the knowledge of the structural, taxonomical and functional characteristics of a rhodolith bed present along the Brazilian continental shelf.

Macrobenthic fauna and the ecological status of a shellfish farm in the Mediterranean Sea (Algeria)

Article

Mar 2024

A faunistic and ecological study on the benthic macrofauna was carried out in the shellfish farm in Ain Chorb (Ain Taya), central Algeria. This study aims to characterise the composition, structure, and functioning of the benthic community to establish the reference state and ecological quality of the shellfish farm and to monitor its evolution through an adapted sampling and observation methodology adapted and used by the scientific community at the international level. Benthic fauna samples were collected in two different periods (warm and cold season) between February 2020 and June 2021; six grab samples were carried out at three sampling stations. Different indices were evaluated based on the benthic community characteristics (species richness, abundance, density, ecological and trophic groups, and the biotic index) and indicator species. An inventory of the macrobenthic fauna of the farm allowed us to identify 6 phyla, 10 classes, 48 families, 106 genera, and 138 species, with a total of 45960 ind/m2. The benthic assemblage is characterised by the dominance of the species Abra alba, Salvatoria clavata, Caecum spp., and Bittium spp. The results of the four benthic indices (the Shannon-Weaver diversity index [H′], the AZTI Marine Biotic Index [AMBI], the multivariate AZTI Marine Biotic Index [M-AMBI], and the BENTIX) indicated that that the sampling stations have a moderate and good ecological status. These results were confirmed by the abundance/biomass comparison curves and geometric abundance class methods. This study provides the first inventory and represents the reference state of the soft-bottom communities of the aquaculture farm. The findings also indicate that the macrobenthic assemblage is excellent indicator of the ecological status.

Jul 2021

Background: This study investigates the marine macroinvertebrate fauna of rhodolith beds (non-geniculated red corallinaceaous algae) in northeast Brazilian. A total of 57 species were identified, belonging to six phyla (Platyhelminthes, Annelida, Sipuncula, Mollusca, Arthropoda and Echinodermata), of which 50 are considered here as new records for the Paraíba State. Annelids (Class Polychaeta) were the most representative taxa in Miramar and Seixas Beaches, while molluscs were dominant in Maceió Beach. New information: This is the first study that includes an identification key, diagnostic features and distribution patterns worldwide and local (including new records) of the marine invertebrate fauna associated with rhodolith beds in northeast Brazil (State of Paraíba). Sampling events were performed in 2018, at low tide in the intertidal to shallow subtidal zones (1.5 and 4.0 m depth), in Miramar, Seixas and Maceió Beaches. A total of 17 species were found for the first time on Seixas Beach, as well as all identified species for Miramar and Maceió. This study tries to contribute to the knowledge of marine invertebrates in northeast Brazilian shallow habitats, providing a baseline for future environmental studies.

Is tourism affecting polychaete assemblages associated with rhodolith beds in Northeastern Brazil?

Article

Full-text available

Sep 2019

Introduction: Rhodoliths are biogenic structures distributed worldwide, formed by several types of calcareous algae. They may host a great diversity of marine invertebrates, among which polychaetes are conspicuous and diversified representatives. Rhodolith beds are notwithstanding vulnerable to several human activities (e.g. exploitation of commercial species associated with rhodoliths, petroleum exploration, fishing activities, effluent discharges, and tourism), which may compromise that diversity. Tourism is presently increasing its impact on rhodolith beds. Global warming and ocean acidification are also determinant factors in faunal change. Objective: to analyse the polychaete assemblages associated with rhodolith beds subject to different intensities of touristic pressure at Seixas Beach (NE Brazil), where tourism is gradually increasing over time. Methods: Effects were evaluated at two depths, 1.5 m and 4.0 m. Sampling was done every two months during 2015, encompassing the two marked seasons of the year in the region (rainy and dry). Quadrats of 15 x 15 cm were placed in each depth during sampling. All rhodoliths present within the quadrat were collected (usually four to five rhodoliths). Our hypothesis was that the deeper depth and the samples from the dry season months would be increasingly subject to the impact of tourism. Results: Overall, 49 species were found (from 21 different families), and a total of 733 individuals were collected. The most abundant species was Eunice wasinensis (280 individuals, 38.2% of total abundance). The species Eurythoe complanata, Eunice biannulata, E. wasinensis, Lysidice ninetta, Oxydromus pugettensis and Ceratonereis (Ceratonereis) singularis appeared in all months. The study detected a tendency for higher diversity to occur at the depth of 1.5 m for all indices, but only the Shannon-Wiener values were significantly higher there (p < 0.05). No clear differences were found regarding months or season. Conclusions: These results suggest that a higher potential pressure due to tourism may occur at 4.0 m due to more intense craft shipping activities (traffic of catamaran boats transporting tourists to and from the reefs) in that area.

Population dynamics and secondary production of Nereis oligohalina (Nereididae : Polychaeta) from a subtropical marsh in Southeast Brazil

Conference Paper

B MAR SCI

The population dynamics and production of Nereis oligohalina Rioja, one of the numerically dominant macrofaunal species in salt marshes of SE Brazil, were studied from May 1987 to June 1988 in Paranagua Bay. Despite large fluctuations in population density (490 ind 0.45 m(-2) in June 1987 to 15 ind 0.45 m(-2) in February 1988), N. oligohalina was present throughout the year. Biomass peaks up to 8.23 g m(-2) were evident in June and September 1987, and January 1988. N; oligohalina undergoes at least two annual reproductive peaks, superimposed upon a background of continuous low-level recruitment. Separation of monthly modal components and the later subjective linkage of modal progressions of average sizes allowed for the identification of four annual cohorts which grossly corresponded to autumn, winter, spring, and summer periods. Instantaneous rates of total mortality were lower for the autumn and winter cohorts. Life spans varied from 5.74 (autumn cohort) to 6.42 mo (spring cohort). Increased rates of total mortality and increased life span in the summer cohort were significantly correlated to higher precipitation rates during this period. The annual production was estimated as 17.94 g m(-2) yr(-1) (Crisp's method) and the P:(B) over bar ratio as 4.5, for formalin fixed wet weight. Temporal variations in population density and biomass of N. oligohalina are strongly correlated to seasonal variations in below ground biomass of Spartina alterniflora. This suggests that the reproductive strategies of the polychaete and the seasonal allocation of energy to below ground tissues of the marsh plant are synchronized.
