Kuwaita sp.

( Fig. 2 F-I)

Lumbrineris ? notocirrata – Gallardo 1968: 86, pl. 35, figs 1-4.

MATERIAL EXAMINED. — Vietnam. Nha Trang, South Vietnam, stn 51, 2 specimens ( LACM-AHF 11448).

DISTRIBUTION. — South Vietnam.

DESCRIPTION

The specimens are incomplete and broken in several pieces (c. 100 setigers maximum), in poor condition. One anterior end with 24 setigers, length through setiger 10 = 4.1 mm, width at setiger 10 without parapodia = 1.2 mm. Prostomium conical; antennae not discernible because of the bad condition of the material. All parapodia well-developed, but setigers 1-7 smaller than following. Notopodia in anterior parapodia button-like, then elongated in middle and posterior region, small and unilobed, each with several notoaciculae ( Fig. 2F ). Simple multidentate hooded hooks with long hoods start on setiger 1; in middle and posterior setigers hoods become proportionally shorter ( Fig. 2G, H ). Maxillary carriers of similar length to maxillae I, slender towards posterior end; maxillae I with welldeveloped bridles; maxillae II with four teeth on both plates, shorter than maxillae I (half their length) and connected to it by well-developed connecting plates; maxillae III bidentate, with the distal tooth the largest; maxillae IV unidentate; maxillae V free, rounded ( Fig. 2I ). It was impossible to determine the characters of the posterior end.

REMARKS

These specimens represent an undescribed species, but the condition of the materials precludes its description.
