Callibaetis
This male imago is a perfect match for Daggy's excellent 1945 description of
C. brevicostatus
(the type was a male imago). Mayfly Central lists
brevicostatus
as a junior synonym of
skokianus
Needham, but the current taxonomy seems a little muddy. In his 1982 U. Minn. doctoral thesis, Gary Check argued that
brevicostatus
Daggy,
skokianus
Needham, and
semicostatus
Banks should all be considered as junior synonyms of
pallidus
Banks. Given the confusing history of the original descriptions and the similarities between them, he could be right. However, the conservative placement would be
C. skokianus
. And, after all, this is an Illinois specimen. :)
