| Phagocata maculata (Stankovic, 1938) | 1935-1937 | 18-30 m | shell zone | 20 specimens dredged. |
| Phagocata undulata (Stankovic, 1960) | Aug 1937 | 16-26 m | shell zone | 32 specimens dredged in Ohrid Bay at depths between 16 and 26 m in the shell zone of the sublittoral. |
| Dendrocoelum maculatum (Stankovic & Komarek, 1927) | prior to 1931 | 0-10 m | | occasionally found in the lower littoral (Chara zone) in Ohrid Bay. |
| Phagocata ochridana (Stankovic & Komarek 1927) | 1935-1937 | | | in Ohrid Bay. |
| Dendrocoelum magnum (Stankovic, 1969) | 1935-1937 | 16-26 m | shell zone | specimens collected in summer in the shell zone of Ohrid Bay (at depth from 16 to 26 m) were sexually mature. |
| Dendrocoelum decoratum Kenk, 1978 | 1935-1937 | 16-36 m | | lives in the sublittoral (shell zone) and profundal zones of Lake Ohrid. A total of about 25 specimens were collected in the summers of 1935 and 1937, all in Ohrid Bay. |
| Dendrocoelum decoratum Kenk, 1978 | 1935-1937 | 37-90 m | | lives in the sublittoral (shell zone) and profundal zones of Lake Ohrid. A total of about 25 specimens were collected in the summers of 1935 and 1937, all in Ohrid Bay. |
| Dendrocoelum dorsivittatum Kenk, 1978 | Sep 1935 | 47-55 m | | two individuals of Dendrocoelum dorsivittatum were dredged in the profundal zone of Lake Ohrid, in Ohrid Bay, on a bottom consisting of soft and hardened mud with few empty Dreissena shells. |
| Dendrocoelum lychnidicum (Stankovic, 1969) | Aug 1937 | 16-26 m | shell zone | about 10 specimens collected in the Ohrid Bay by dredging in the shell zone of the sublittoral. The animals are comparitively rare and can easily be overlooked because of their small size and slow movements,. |
| Dendrocoelum ochridense (Stankovic & Komarek, 1927) | 1935-1937 | 10-36 m | | summer months in Ohrid Bay on Chara (10-15 m depth) and in the shell zone (15-36 m) by dredging and using meat bait. |
| Dendrocoelum minimum Kenk, 1978 | 1935-1937 | 30-52 m | | uncommon species, though it may easily be overlooked on account of its size. Only four mature specimens were taken, all in Ohrid Bay, below the shell zone. |
| Dendrocoelum albidum Kenk, 1978 | 1935-1937 | 16-30 m | | dredged in the shell zone. Both mature and young individuals were taken. This species seems to be rather common in the shell zone but is easily overlooked on account of its small size. |
| Dendrocoelum translucidum Kenk, 1978 | Sep 1935 | 40-90 m | | lives in the profundal zone of Lake Ohrid. A total of about 60 specimens, the majority of them sexually mature, were dredged in September 1935 in Ohrid Bay. |
| Dendrocoelum cruciferum (Stankovic, 1969) | 1935-1937 | 16-29 m | | Only 11 specimens (9 immature and 2 mature) were collected in Ohrid Bay by dredging from 16 to 29 m, on on bait (meat and dead fish) at 28 m. This species is rapaceous and presumably preys on other triclads that abound in the sublittoral zone. |
| Dendrocoelum lacteum (Müller, 1773) | prior to 1938 | | | found an individual of this species on a specimen of a sponge, Ochridaspongia rotunda, dredged in Ohrid Bay. |
| Dendrocoelum lacteum (Müller, 1773) | 1935-1937 | 16-30 m | | collected in Ohrid Bay at depths ranging from 16-30 m. |
| Dendrocoelum lacteum (Müller, 1773) | 1935-1937 | 47-90 m | | occurs in the profundal zone. |
