Aquatic oligochaetes were collected from the fine sediments of eight cave streams in Illinois and Missouri from June 1998 through January 2000. Five families, 9 genera, and 15 taxa are reported. Rhyacodrilus subterraneus (Tubificidae) represents a new state record for Illinois, and 10 species-Dero digitata, D. nivea, and Pristina leidyi (Naididae) and Limnodrilus cervix, L. hoffmeisteri, L. udekemianus, Rhyacodrilus falciformis, R. sodalis, R. subterraneus, and Varichaetadrilus angustipenis (Tubificidae)- represent new state records for Missouri. Of the species collected, Haplotaxis cf. gordioides (Haplotaxidae), P. leidyi, and L. hoffmeisteri, R. falciformis, R. subterraneus, and Tubifex tubifex (Tubificidae) have previously been reported from caves in North America. These are the first published records of freshwater oligochaetes in caves of Illinois and Missouri.
