Ruddy ID

Male Ruddy Darter at Banks on Saturday. Tick off those features that distinguish it from a male Common Darter.
Deep red abdomen with a clubbed base not orangy and parallel as Common
Yellow patch at base of hindwing
All black legs not black with yellow stripes.
Plain thorax not yellow streaked
and if you want to count the cells below the radial supplemental vein (Rspl) on the wing there should be four or five
