Sigambra constricta (Southern, 1921)

Material

One specimen, Telegraph Bay, sample no. 7, Cape d’Aguilar, Hong Kong. 22 ° 129200 N 114 ° 159100E; sediment 6% gravel, 63% sand, 31% silt/clay, depth 9 m, water temperature 26 ° C (NHM. 2003.1080) .

This is one of two species of Sigambra which have already been recorded from Hong Kong waters (e.g. Shin and Thompson 1982). It has 14 pharyngeal papillae, a notopodial capillary seta on mid-body to posterior chaetigers and is without notopodial hooks on the anterior 29 or so chaetigers. The substratum in Telegraph Bay was sandier than that in Conic Island Cave.
