Neanthes willeyi ( Day, 1934) View in CoL , new record

Material examined. Ramin Jetty ( 25° 16' 31.00" N, 60° 44' 59.00" E), ZUTC 7074 , intertidal zone, rocky, collected by Bonyadi-Naeini A., 16 January 2015 GoogleMaps .

Remarks. Fauvel (1911) mentioned Neanthes willeyi under the original name Neanthes capensis Willey, 1904 , but it is now accepted as Neanthes willeyi ( Day, 1934) ( Read & Fauchald 2024) . Mohammad (1971) reported Neanthes willeyi as Nereis (Neanthes) willeyi from the Persian Gulf; Wehe & Fiege (2002) regarded it as an endemic species in the Red Sea. We report this species from the Gulf of Oman as a new record. Two specimens were examined. They differ from specimens of Neanthes deplanata Mohammad, 1971 in the numbers of paragnaths: they have more conical paragnaths in Area III (20 vs 14–15) and fewer paragnaths in Area V (0 vs 2). The specimens we recorded from Gulf of Oman have fewer paragnaths in Area V (0 vs 1–3) than Neanthes biparagnatha Bonyadi-Naeini et al., 2017 . Also, they have no superior neuropodial lobes (SupLo), which are present in Neanthes biparagnatha .
