C. rastricornis based on Patrick's comments under this shot?

Could very well be. Do you think I should submit it as that? I have no experience with fishflies. Maybe it is something I should have collected (Actually, I probably should have, as I have a taxonomy class coming up).

Yes, male C. rastricornis
Black marks on head and pronotum distinctive for this species, especially visible here:



Date is also distinctive, I believe. Guide to the Megaloptera and Aquatic Neuroptera of Florida quoted in the guide page says:

Larval collections of Chauliodes from Florida are scant compared to the numerous adult collections. Chauliodes rastricornis is the more common of the 2 species and adults have been collected year-round in Florida, whereas adults of C. pectinicornis have been collected primarily during Spring and Summer months....

The pectinate (comb-like) antennae show this is a male.

A nice addition, showing the winter occurrence in Florida.
