A New Species of Scaleworm, Grubeulepis malayensis (Annelida : Polychaeta : Eulepethidae), from Morib Beach, Malaysia, Living in Chaetopterid Tubes

Abstract

A new species of eulepethid polychaete, Grubeulepis malayensis, is described. It lives in empty tubes of the chaetopterid polychaete Mesochaetopterus selangolus (Rullier, 1976) collected from a sandy beach at Morib Beach, near Kuala Lumpur, Malaysia. The species is distinguished by the lack of papillae on the first pair of elytra, possession of spinous notopodial hooks, and the presence of acicular neurochaetae on segments 2 to 5. It is unique in its genus in possessing a single pair of prostomial eyes and in having a short anal cirrus on the right side.
