Many Oligochaeta were collected during recent investigations in Southern-European caves. This is the first contribution in which some data concerning the Tubificidae are summarized. Three new species of Rhyacodrilinae, including a new genus, are described: Rhyacodrilus omodeoi n. sp., Rhyacodrilus dolcei n. sp., Rhyacodrilus gasparoi n. sp. and Stochidrilus glandulosus n. gen., n. sp. The poorly known species Frearidrilus pescei (Dumnicka 1981, augm. 1987) is redescribed on the basis of new material collected in Slovenian caves; this revision allowed the proposal to ascribe it to the genus Tubifex, considering the monospecific genus Frearidrilus as a junior synonym of Tubifex.Une importante collection d'Oligoch?tes a ?t? r?colt?e lors de prospections r?centes de nombreuses grottes d'Europe m?ridionale. Dans cette premi?re contribution ? l'?tude de ce mat?riel, trois esp?ces nouvelles de Rhyacodrilinae, dont l'une appartient ? un genre nouveau, sont d?crites : Rhyacodrilus omodeoi n. sp., Rhyacodrilus dolcei n. sp., Rhyacodrilus gasparoi n. sp. and Stochidrilus glandulosus n. gen., n. sp. Frearidrilus pescei (Dumnicka 1981, augm. 1987), esp?ce peu connue, est red?crite ? partir de mat?riel nouveau r?colt? dans des grottes de Slov?nie; cette r?vision a permis de proposer l'inclusion de cette esp?ce dans le genre Tubifex; le genre Frearidrilus, monosp?cifique, est donc consid?r? comme synonyme de Tubifex. |
