Abstract

A capitellid species, Heteromastus filiformis ($Clapar\grave{e}de$, 1864) is newly reported from Korean waters with the description and illustrations. Korean materials of the present study show several characteristics generally agreed well with the previous descriptions of H. filiformis as follows: the thorax is composed of the first achaetigerous peristomium and following 11 thoracic chaetigers; the capillary chaetae are present on the thoracic chaetigers 1-5 and narrowly bilimbate; the thoracic hooded hooks are appeared on the chaetigers 6-11 and have indistinct nodes on the shaft and several teeth above the main fang; the abdominal hooded hooks possess distinct nodes on the shaft and a few teeth above the main fang; the branchiae appearing on the posterior abdominal segments are the broadly-based and rounded lamellae projecting posteriorly. The authors reviewed the taxonomy of Heteromastus with a comparison of morphological characteristics among worldwide species, and provided a key of them.
