A new species of <i>Pachycordyle</i> (Hydrozoa, Clavidae) from Lake Biwa (Japan), with remarks on this and related Clavid genera

“…Pachycordyle has been found in shallow waters of the Bay of Naples and other parts of the Mediterranean (Adriatic and Aegean Seas); the western Atlantic (Wedler and Larson, 1986); Bermuda (Calder, 1988); possibly Nassau Harbour, Bahamas, as abortive medusoids (Mayer, 1910); and lakes of Japan (including the entirely freshwater Lake Biwa as well as the brackish Ono River -Lake Kahokugata, connected to the Sea of Japan). They occur mainly at salinities of 0-20 ‰, but in Bermuda, near Harrington Sound, Calder (1988) found a 2 mm high colony at 2 m depth in water with a salinity 35-36‰.…”
