Dasineura investita
Joe, I described this gall midge from Laportea canadensis, as Dasineura investita Plakidas 2012. (Cecidomyiidae). This is the smooth,ovoid leaf gall. There are three other new species from Laportea canadensis: The hairy stem gall, Dasineura pilosa; the polythalamous leaf gall, Dasineura involuta; and a basal stem gall, Neolasioptera laporteae.
They occur here in Allegheny County, Pennsylvania. The new species descriptions are in "The Gall Midges Of Allegheny County PA". If your interested, reprints will be available in Spring 2013.

I can't find any reference to "The Gall Midges Of Allegheny County". Can you provide a complete citation? Is the name available now under ICZN rules?
