Byers 1962
Diagnosis (Adapted from Webb et al., 1975): Wings with clear background color, crossveins not margined. Apical band dark brown, usually continuous but sometimes with clear spots on posterior part. Pterostigmal band brown, continuous. Marginal spots absent. Male terminalia dark yellow to brown. Ninth tergum deeply truncate. Hypovalve broad and divergent apically reaching to distal quarter of basistyle. Ventral paramere broad, unbranched, barbed, reaching between dististyles. Dististyle with large broad lobe.
P. galerita has been collected from June to July. This species can be confused with P. subfurcata because of the large accessory lobes on the dististyle. However, these species can be separated on the basis of the thickness and orientation of the hypovalves. In P. galerita they are thick and divergent and in P. subfurcata they are thin and elongate.
This northeastern species was previously known from Quebec and Vermont west to Ohio, with an apparently disjunct population in Wisconsin. The Ontario collections reported here narrow that apparent disjunction. Thornhill and Johnson (1974) did not record P. galerita from Michigan, nor is it recorded from Michigan on a current web list of Michigan Mecoptera (O’Brian, 2006).
