New records of sclerozoan fan worms in Acropora sp. from the Gulf of Mannar, south-eastern coast of India (Annelida: Sabellidae)

Two species, of the sabellid annelid genera Acromegalomma Gil and Nishi, 2017 and Notaulax Tauber, 1879, are reported associated with dead coral (Acropora sp.) in the Gulf of Mannar, south-eastern coast of India. The record for Acromegalomma quadrioculatum (Willey, 1905) constitutes the first report of this species from the Gulf of Mannar, whereas Notaulax pyrrhogaster (Grube, 1878) constitutes the first record of this species in India.
