Abstract

A new genus and species of an interstitial priapulid is described from a coarse sand beach at Korolevu on Viti Levu, Fiji. This is the first interstitial priapulid described from the South Pacific Islands and it occurs in both intertidal and shallow subtidal sands. It is characterized by a bulbous introvert with numerous scalids, an elongate trunk with anterior scalids and a posterior circle of hooks, lack of a tail, pectinate pharyngeal teeth, a polythyridium, and separate sexes. It differs from the Caribbean species, Tubiluchus corallicola, in lacking a posterior appendage, showing no sexual dimorphism and having different types of cuticular scalids.
