New State Stonefly (Plecoptera) Records For Pennsylvania, With Additional Records And Information On Rare Species Author Earle, Jane I. text Illiesia 2009 5 16 169 181 journal article 6786 10.5281/zenodo.4759416 07c83cbb-d592-43c1-894e-9fbcd0f48339 1854-0392 4759416 Allocapnia aurora Ricker is limited to small, mostly forested or rural coldwater creeks in the lower Susquehanna River basin and the extreme eastern portion of the Potomac River basin in southcentral Pennsylvania . Allocapnia aurora was previously confirmed from only 10 Pennsylvania creeks ( Masteller 1996 ). Although not as rare as certain other Pennsylvania Allocapnia , it is included here to correct earlier misidentifications. Males can be difficult to separate from A. pygmaea and A. nivicola . Male Allocapnia from Indian Creek in Westmoreland County and French Creek in Chester County that were identified as A. aurora ( Earle 1994 and 2003) were actually A. nivicola . The A. aurora records from Muddy Creek in York County ( Masteller 1996 ) were also misidentified and were actually A. pygmaea .
