Zealeuctra fraxina Ricker and Ross

New record: MONTGOMERY (D): on the PA Rte. 29/73 bridge over Mine Run, Schwenksville, PA, near the confluence of Perkiomen Creek , 4 March 2006, 1♂ (CL). The reported range of Z. fraxina is from West Virginia west to Illinois and south to Tennessee. Zealeuctra fraxina was collected in southeastern Pennsylvania and is the farthest eastern known record for this Nearctic genus. The closest reported occurrence is in the Potomac River basin in the eastern panhandle of West Virginia, the only West Virginia record ( Tarter and Nelson 2006), over 250 km away. The genus Zealeuctra is most common in the midwestern United States south to Alabama and Texas, where several additional species are present and where the nymphs are most often associated with low order intermittent streams ( Ricker and Ross 1969, Kondratieff and Zuellig 2004, Grubbs 2005). In the Ozarks, Zealeuctra are restricted to limestonebased intermittent streams ( Poulton and Stewart 1991).
