First record of the fissurellid mollusc Diodora funiculata (Reeve, 1850) (Mollusca: Gastropoda) in Libyan waters (central Mediterranean Sea)

The Tripoli Harbour, with its cosmopolitan shipping traffic, is a well-known hub for alien molluscs. This is confirmed here by the first report of the Indo-Pacific fissurellid mollusc Diodora funiculata from Libya. While its arrival pathway remains unknown, shipping or natural dispersal from other populations in the Mediterranean Sea may constitute a possible vector. The high number of specimens and shells found suggest an establishment in the area. However, this should be confirmed by additional field work.
