New Information on the Hosts and Distribution of the Marine Fish Leeches Trachelobdella Lubrica and Pontobdella Muricata (Clitellata, Hirudinida)

Fish leeches collected in the Aegean Sea, the Sea of Marmara and the Black Sea were examined. Trachelobdella lubrica (Grube, 1840) was recorded for the first time from the ballan wrasse Labrus bergylta (Osteichthyes, Labridae), marine bream Diplodus vulgaris (Osteichthyes, Sparidae) and the grouper Epinephelus aeneus (Osteichthyes, Serranidae) from aquiculture. The leeches of this species were found in the Aegean Sea and the Sea of Marmara on the body surface, in the mouth and gill cavities of their hosts. Leeches identified as Pontobdella muricata (Linnaeus, 1758) were collected from the thornback ray Raja clavata (Chondrichthyes, Rajidae) in the Black Sea.

The aim of this research was to test the ability of hybridizing Hirudo orientalis S. Utevsky et Trontelj, 2005 and Hirudo verbana Carena, 1820. We obtained offspring from both species. The color pattern of all the hybrids was uniform and quite different from both the parents. The venter was similar to H. verbana. The dorsum was very similar to the color pattern of Hirudo medicinalis Linnaeus, 1758 that was not involved to the experiment. The coloration pattern of the hybrids, which is very similar to that of H. medicinalis suggests the hybrid origin of this species.
