2 NEW SPECIES OF HYALINECIA (POLYCHAETA, ONUPHIDAE) FROM DEEP ZONES OFF NEW-CALEDONIA (SOUTHWEST PACIFIC-OCEAN)

Two new species belonging to onuphid genus Hyalinoecia were collected from bathyal and abyssal zones off New Caledonia in the southwest part of Pacific Ocean. Hyalinoecia abranchiata n. sp. is characterized by the lack of branchiae, a character seldom seen in the genus, and with a brown elongated ring on each posterior lateral antennae. H. bathyali s n. sp. with ovoid frontal palps, bifid acicular setae without hoods, branchiae from setigers 21-28 chiefly differs from H. tubicola longib ranchiata McIntosh, 1885 in the lack of dark pigment spots, and from H . tubicola (Muller, 1788) and H. artifex Verrill, 1880 in the shape of the acicular setae. Morphological differences and geographic and bath ymetric distributions are shown by a comparison between the eight othe r known species of Hyalinoecia around the world and these two new spec ies.
