Nereididae (Annelida: Polychaeta) from intertidal habitats in the Gulf of Oman, Iran

Abstract

The species composition and distribution patterns of Nereididae (Annelida: Polychaeta) from the north coast of Gulf of Oman were investigated. Specimens were collected from ten intertidal sites along the Iranian coast, including mangrove, muddy, boulder and rocky, coral and sandy-rocky shore habitats. Eight species of Nereididae were identified: Leonnates decipiens Fauvel, Nereis coutieri Gravier, Neanthes deplanata Mohammad, Perinereis nuntia (Savigny), Perinereis heterodonta Gravier, Perinereis cultrifera (Grube), Perinereis horsti Gravier and Pseudonereis trimaculata Horst. The eight species are redescribed and two Perinereis species, P. heterodonta and P. horsti, currently junior synonyms of P. nuntia and P. vancaurica (Ehlers) respectively, are raised from synonymy. All reported species are new records for the Gulf of Oman, bringing the known total number of species in the family to twelve; P. trimaculata is also a new record for the Arabian Sea–Arabian Gulf region. Nereidid diversity within the region is comparable to other Indo-Pacific coastal regions, and higher than other parts of the world.

Review of some Perinereis Kinberg, 1865 (Annelida: Nereididae) species of Group 2 sensu Hutchings, Reid & Wilson, 1991 from the Eastern and South-eastern Asian seas

“…Two additional species need to be included in Perinereis S2A due to having this subgroup's characteristic features: Perinereis horsti Gravier, 1902 from Djibouti was previously considered a junior synonym of P. vancaurica , but it was re-established and treated as a valid species (Yousefi et al ., 2011); whereas P. linea (Treadwell, 1936) from China was recognized as different to his previous senior synonym P. aibuhitensis (Arias et al ., 2013) and is confirmed as a valid species in this study. The five species formerly considered in Neanthes but here transferred to Perinereis also have characteristic features of G2 species: Perinereis babuzai comb.…”

Intertidal polychaetes from Abu Musa Island, Persian Gulf, with a new species from thePerinereis cultriferaspecies complex (Annelida: Nereididae)

“…Yousefi et al . (2011) recorded P . cultrifera from the Persian Gulf and Gulf of Oman, their material matches exactly with the syntypes as re-described by Hutchings et al .…”

“…Reexamination of Yousefi's material and the material obtained from Abu Musa shows that the latter differs in the number of paragnaths in areas I, III, IV with more cones than recorded by Yousefi et al . (2011). Also they differ from the re-description of the syntypes by Hutchings et al .…”

“…Of the 10 Perinereis species recorded from the Persian Gulf only one, P. cultrifera (Grube, 1840), belongs to the P. cultrifera species complex. The species has also been reported in the Red Sea, Suez Canal, Gulf of Aden, the Persian Gulf, Gulf of Oman (Wehe & Fiege, 2002; Yousefi et al ., 2011) Hong Kong (Muir & Bamber, 2008) and northern Bay of Bengal (Muir & Maruf Hossain, 2014). Perinereis cultrifera floridana was recorded by Mohammad (1971) from the Persian Gulf.…”

The intertidal polychaete (Annelida) fauna of the Sitakunda coast (Chittagong, Bangladesh), with notes on the Capitellidae, Glyceridae, Lumbrineridae, Nephtyidae, Nereididae and Phyllodocidae of the “Northern Bay of Bengal Ecoregion”

“… Perinereis nuntia has been studied by Glasby and Hsieh (2006) , Wilson and Glasby (1993) and Yousefi et al (2011) , and as Alam et al (1996) did not give a full description of their specimens, it would be better to refer them to the Perinereis nuntia (Savigny, 1818) species group. The specimen 1937.1.4.43-44 from Maungmagaun, Myanmar, has been studied and identified as Perinereis nuntia as defined by Glasby and Hsieh (2006) .…”
