      Vladykov VD, Kott E. () A new nonparasitic species of the Holarctic lamprey genus Lethenteron Creaser and Hubbs, , (Petromyzonidae) from northwestern North America with notes on other species of the same genus. There are 38 species of living lampreys, 18 parasitic and 20 nonparasitic. The parasitic species feed as adults, while the nonparasitic do not. The taxonomy and systematics of the living lampreys is based primarily on dentition characters. Since the number of oral fimbriae and oral papillae have never been systematically investigated in lampreys, we compared them in 17 of the 18 parasitic.

      The Northern Hemisphere lamprey genus Lethenteron was originally erected as a sub-genus of Entosphenus by Creaser and Hubbs () and elevated to generic rank by Jordan et al. (), without justification. Vladykov and Follett () accepted this action and defined members of Lethenteron as possessing posterial teeth in a single. A non-parasitic lamprey. At about 4 years of age transforms from ammocoete in fall, moves downstream into lakes over winter; spawns the following spring and summer in shallow of lakes and rivers (Ref. ). Spawning period between 11 June and 25 September in Naknek River Basin, Alaska. Fecundity, 2,, eggs/female.

      Arctic lamprey has high quality flesh rich in fat (Ref. ). Around it was of great importance for native peoples along the Yukon River at Russian Mission and Anvik, Alaska, where they would catch upstream spawning migrants by the dozens through the ice using long multi-forked poles or dipnets (Turner, , Nelson, ). Abstract.—There are 11 lamprey species in Canada: Vancouver lamprey En-tosphenus macrostomus Alaskan brook lamprey Lethenteron alaskense, American brook lamprey Lethenteron appendix include unequivocal evidence as to whether parasitic and nonparasitic members of a paired species should be considered distinct species and information on the.
