Type locality.

Gulf of Naples (western Mediterranean Sea).

Distribution.

Circumtropical. Mediterranean Sea: WB, CB, AD, AS, LB. New record for the Israeli coast.

Habitat.

From infralitoral depths to 760 m, on hard substrates, among algae, corals, hydrozoans, sponges and Posidonia oceanica rhizomes, in vermetid reefs, in coarse sand.

Remarks.

Specimens from Greece have a faint or no visible trepan. Individuals without trepan but otherwise identical to Trypanosyllis coeliaca have in the past been identified as Pseudosyllis brevipennis Grube, 1863, but according to San Martín (2003) the absence of the trepan can be attributed to a number of reasons, including loss, and Pseudosyllis brevipennis is regarded as a synonym of Trypanosyllis coeliaca .
