Salmonflies
Pteronarcys californica

The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

This wild-looking little thing completely puzzled me. At first I was thinking beetle or month larva, until I got a look at the pictures on the computer screen. I made a couple of incorrect guesses before entomologist Greg Courtney pointed me in the right direction with Psychodidae. He suggested a possible genus of Thornburghiella, but could not rule out some other members of the tribe Pericomini.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

This topic is about the Mayfly Genus Caudatella

This Western genus is unimportant, but Caudatella heterocaudata and Caudatella hystrix are said to sometimes produce fishable hatches.

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

Luke-

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
