The paper is in press now, so I can share an updated taxonomic synopsis of the "unimportant" genus Caudatella. Have fun.

Caudatella edmundsi (Allen, 1959)

Caudatella columbiella (McDunnough, 1935), comb. n.
= Ephemerella californica Allen and Edmunds, 1961, stat. n., syn. n.

Caudatella heterocaudata (McDunnough, 1929)
= Ephemerella circia Allen and Edmunds, 1961, stat. n., syn. n.

Caudatella hystrix (Traver, 1934)
= Ephemerella spinosa Mayo, 1952
= Ephemerella cascadia Allen and Edmunds, 1961

Caudatella jacobi (McDunnough, 1939)
= Ephemerella orestes Allen and Edmunds, 1961

From your posting, it appears that what was previously Caudatella heterocaudata and its (3) subspecies are now Caudatella heterocaudata (with no subspecies), and (new species), Caudatella columbiella. Is that correct?

columbiella was an old species that was synonymized with heterocaudata; i think it is a separate species

circia, californica and heterocaudata were all subspecies of heterocaudata

it turns out that californica is the same thing as columbiella

circia does not hold up as a nominal entity under most current philosophies. at the time it was described, the authors acknowledged that it probably interbred with other variants of heterocaudata, and the defining characters varied even in the population at the type locale. so, it should be considered the same species as heterocaudata
