| Summary: | Paramononchus arcticus n.gen., n.sp., Coomansus fletcherensis n.sp., and Mononchus superbus n.sp. from the Mackenzie and Porcupine river systems and Somerset Island are described and illustrated. Paramononchus n.gen. is closest to Mononchus Bastian, differing in having the dorsal tooth opposed by a denticulated rib with two small basal teeth and a transverse rib at the level of the dorsal tooth. Other mononchids from the river and lake samples are described and illustrated including Coomansus gerlachei and Mononchus maduei which are reported for the first time in Canada.A new genus Parahadronchus is defined with Parahadronchus adamanicus (Jairajpuri, 1969) n.comb. as its type species, and generic diagnoses and a key to the 23 recognized genera of Mononchidae are included. |
