Redescription and designation of lectotypes of the North American Cambarincola okadai Yamaguchi, 1933 (Annelida : Clitellata : Branchiobdellidae)

Unlabelled specimens found in the slide collection of Prof. Hideji Yamaguch i were identified as the North American species, Cambarincola okadai Yamagu chi, 1933. As no type specimens had been designated, a detailed redescripti on was made and the specimens were designated as lectotypes for the species . Specimens of this species were named Triannulata montanus Goodnight, 1940 , then subsequently redescribed and transferred to Cambarincola montanus. T he latter two names now become junior synonyms of C.okadai.
