Nesemann, H.: Investigations on two Glossiphonia species (Hirudinea) from running waters of Central Europe with a redescription of Glossiphonia concolor (Apáthy, 1888)

Two Glossiphonia species 73 (

G. verrucata

, G. complanata

, G

. paludosa ) were found in the river Kinzig and in the upper reach of the river Rhine (

G

. verrucata

, G. complanata

, G. concolor

; leg. NEUBERT et EPPLER). These faunistical data clearly indicate the original status of the Danubian fauna, which did not really change during the glacial periods. LEECH COMMUNITIES IN BROOKS

, STREAMS AND SMALL RIVULETS Rhine- A total number of 43 localities in streams of the plain of the Upper Rhine was detected. G. complanata was found at 18 localities (42%), while G. concolor (from 3 collectings) and G. verrucata (from 2 collectings) became rare. In the rhitral reach, 121 localities in the streams of mountainous regions, inhabited by leeches, were controlled (Odenwald, Spessart, Vogelsberg, Taunus, Westerwald). G. complanata occurs often with high abundances at 60 localities (50%), but also G. verrucata is common (41 localities, 34%). Both, living together, were found at 19 localities (18%). Danube- In the western parts of the Hungarian Great Plain (Austria) the distribution of Glossiphonia species was investigated in the tributaries of the river Danube (streams and smaller rivers, total number of 32 localities excluding the river March) G. concolor lives at 5 localities (16%), G. verrucata at 19 localities (59%), G. complanata at 13 localities (41%) and G. paludosa at 8 localities (25%). Sympatric occurrences of G. com- plana

ta and G. verrucata were observed at 28% of the controlled localities. In the mountainous regions (Wienerwald, Leithagebirge

, total number of 38 localities) - G. verrucata (21%), G. complanata (34%) - nowhere could I find both species living together. Only G. complanata enters two of the small brooks in the Leithagebirge

. G. concolor and G. verrucata were found living together in an output of an artificial lake. REFERENCES APATHY, I. (1888): Süsswasser-Hirudineen
