Syllis oligochaeta Bobretzky, 1870: 229 –230, figs 51–52

Type material. Black Sea.

Remarks. The species was considered as a synonymy of Haplosyllis spongicola (Licher 1999) . There is a single report, the description it not accurate enough as required to characterize the species, and the type material is not available.

Haplosyllis violaceo-flava (Grube, 1878)

Syllis violaceo –flava Grube, 1878: 115 –116 T. VII, fig. 3.

Type material. Philippines, Bohol.

Remarks. Licher (1999) considered Haplosyllis violaceoflava as a synonymy of Haplosyllis spongicola, It has not been possible to assess the validity of the species, as the type material is probably lost. The chaetae were not well described in the original description, as being simple bifid chaetae apparently very similar to those of H. uncinigera . Additionally, the dark spots on the anterior segments, which were mentioned by Grube (1878), are also present in some specimens of H. uncinigera .
