Moved from Orthonevra.
I guess these will have to go to the species group page, at least for now. Thanks John.

pictipennis group
All these with a single, horizontal line across the eye are in the Orthonevra pictipennis group. Apparently the species are all easily distinguished from each other by general appearance -- wing and fore tibiae. Unfortunately the revision of the group (Sedman 1966) contradicts itself on at least one essential point so you'll need to see reliably identified specimens to figure which is which. This is probably one of pictipennis or pulchella; these are the two the revision says have darkened fore tibiae.
