Two of the species Dodds described in this paper have been lumped into Baetis tricaudatus. They are Baetis moffatti and Baetis intermedius.

Quote from page :"McCafferty et al. (1993) suggested the possibility that B. moffati and B. magnus represent the same species. However, neither the original description of B. moffati presented by Dodds (1923) nor Traver's (1935) redescription agree with our reared material of B. magnus. We have attempted to collect B. moffati from its type locality (South Boulder Creek near Tolland, Colorado), but to date, no Baetis species have been collected or reared from this locality that match these descriptions. Additionally, no larvae of B. magnus have been collected from South Boulder Creek, however, B. tricaudatus and B. bicaudatus are abundant in this stream."

Quote from page 256: "This species is known only from Colorado and has not been reconfirmed since 1935. This may be the result of of it not being known in the larval stage. However, there is some possibility that B. moffati and B. magnus are equivalent. The adults of both are essentially similar, but this is not enough evidence for proposing synonymy because the adults of all species of the rhodani group of Baetis, to which they belong are similar." They report this species from Gothic.
