J. BROMLEY HEATHER

Eleven species of leeches are recorded from Israel, and their diagnosis, distribution, and biology are given. In addition, notes are given on five species identified from Israel in the past, but not recorded in this survey. These latter include one species inquirenda; thus the number of confirmed leech records now stands at fifteen. Three species belong to the family Hirudinidae, three to Erpobdellidae, and nine to Glossiphoniidae. Information is also given on leeches from other Levantine countries (Jordan, Lebanon, and Syria), as well as from Egypt, Saudi Arabia, and Turkey.

HEATHER J. BROMLEY

Dendrocoelum dani n. sp. is recorded from two sites in northern Israel, Dan and Baniass. D. dani is characterised by the presence of several pairs of eyes; a large and well differentiated adenodactyl, much larger than the short conical penis; and the absence of a bursa copulatrix which is replaced by bursal-intestinal communications. D. dani is diploid with 16 pairs of mitotic chromosomes. Sexual reproduction occurs throughout the year at temperatures lower than 18°C. Asexual reproduction is unknown.

Atrioplanaria aquaebellae n. sp. is recorded from 12 spring-fed habitats in northern Israel. Its morphology is described from asexual and almost fully mature, laboratory cultured specimens. Asexual reproduction involves the degeneration of the pharynx and, where present, the reproductive system.

Freshwater nemertines of the genus Prostoma Dugès are recorded for the first time from Israel. Specimens were collected from the Jordan Valley and the Jerusalem area which represent two different drainage systems.

HEATHER J. BROMLEY and MARIO BENAZZI

Two new species of freshwater triclads belonging to the Dugesia gonocephala species group are described, D. golanica n.sp. from northern Israel and D. libanica n.sp. from Bécharré in northern Lebanon. D. golanica is characterized by a large, solid, bilobed adenodactyl positioned dorsally and to the right of the pointed penis papilla, while D. libanica has a large, solid, conical-shaped adenodactyl situated dorsally and to the right of the asymmetrical, finger-shaped penis papilla. These two species are clearly related to each other and to D. iranica (Livanov) from Iran and Turkey.
