Notes on some enigmatic taxa of limnoterrestrial rhabdocoels, with the description of two new species.

Six taxa of limnoterrestrial rhabdocoels are discussed, two of them, both belonging to Typhloplanidae Graff, 1905, are new to science. Adenoplea reisingeri n. sp. can be distinguished from its congeners by the absence of a separate seminal receptacle, the presence of a copulatory bursa and the fact that it has an unarmed copulatory organ. Carcharodopharynx schlitzensis n. sp. can be distinguished from C. arcanus (Reisinger, 1924) Poche, 1926, the only other species within the genus, by the fact that the cirrus bears spines. For four other taxa: Adenoplea perigraptopera Reisinger, 1924, A. meridionalis Kolasa, 1981, C. arcanus (Reisinger, 1924) Poche, 1926 and Archivortex silvestris Reisinger, 1924, new data on morphology and distribution are provided. Neotypes are designated for A. perigraptopera and C. arcanus.

Contribution to the freshwater gastrotrich fauna of wetland areas of southwestern Ontario (Canada) with redescriptions of seven species and a check-list for North America.

This study gives additional, detailed information on the freshwater gastrotrich species described and reported from the southwestern regions of Ontario and New Brunswick, Canada by Schwank (1990). Aspidiophorus ontarioniensis, Chaetonotus (Chaetonotus) furculatus, Chaetonotus (Chaetonotus) ontariensis, Chaetonotus (Primochaetus) annae, Ichthydium malleum, Lepidodermella forficulata and Setopus lemnicola are all redescribed. In addition, a complete list of freshwater species currently known from North America is given.
