TypesSyntypes, Museum of Comparative Zoology, Harvard University, Cambridge, Massachusetts 188 (2 male I, 2 ovigerous female.) The "paratypes" of Faxon (1914), Museum of Comparative Zoology, Harvard University, Cambridge, Massachusetts 3355 (1 male I), are dubious "types" because this number was not listed by Hagen (1870:73). Douglas G. Smith examined Museum of Comparative Zoology, Harvard University, Cambridge, Massachusetts lots 3355, listed as paratypes by Faxon (1914:421), and 1841, listed as such by Hagen (1870:73), and found the former to contain a first form male of O. immunis from Belleville, Illinois, the latter, a marine crustacean from Society Island. Probably Hagen erred in recording the specimen from Belleville as having been catalogued under number 1841. The "paratype" said to be in Museum National d'Histoire Naturelle, Paris, France could not be located.
RangeMaine and Connecticut to eastern Colorado and Wyoming, and from Alabama to southern Manitoba, Ontario and Quebec. Its presence in New England probably resulted from introductions (Douglas G. Smith, in litt.).
