This species is generally characterised by the parallel cubital and discal vein, but these veins are often somewhat convergent, as also Strobl states. The species is not easily distinguished from pallidiventris (see below under this species). is common in Denmark; Ermelund, 0rholm, Tisvilde, Nordskoven at Jaegerspris; in Jutland at Aalborg; my dates are ^"-;5—-^'v.
