Armandia cf. bipapillata Hartmann-Schröder, 1974

Material

Numerous specimens from site D, back of the cave, one specimen from site A at the cave mouth, Fan Tsang Chau (Conic Island) Cave .

This material is generally indistinguishable from the description of Hartmann- Schröder (1974), but is smaller, and the prostomial triad of eyes was not visible in live specimens. The holotype, from Mozambique, was 21 mm long with 32 chaetigers. Six specimens from Conic Island Cave ranged between 7 and 12.5 mm long for 30 to 31 chaetigers. Gills are present on all but the first chaetiger, lateral eyes are present on chaetigers 7 to 17 or 18; the pygidium bears six threadlike cirri and eight round papillae (eight and ten respectively in the type material) .

Al-Hakim and Glasby (2004) were the first to record Armandia bipapillata from the South China Sea, from the Natuna Islands, east of Singapore.

The only opheliid recorded from Hong Kong waters by Shin (1998) was Ophelina acuminata Örsted, 1843 (see also Mak [1982] as Ammotrypane aulogaster ), to which Ong Che et al. (1999) added O. grandis (Pillai, 1961) . Huang (2001) lists Armandia intermedia Fauvel, 1902 , A. leptocirrus Grube, 1878 and A. lanceolata Willey, 1905 from Chinese waters, the first two from the South China Sea.
