Some closeups of facial images to aid in identification:
Misumessus:
ALEs larger than AMEs.
Misumena:
All four anterior (front) eyes are about the same size. When viewed from the front, and a little above, it seems all eight eyes are visible and form a crescent shape. The lateral eyes are on tubercles, but the posterior laterals are visible. See
Misumenoides:
All four anterior (front) eyes are about the same size. When viewed from the front, and a little above, only six eyes are visible. The posterior laterals are facing sideways and are on the ends of a long horizontal transverse ridge across the face. Eric says "Misumena has essentially no black markings (while Misumenoides may have some), which is how you can tell them apart in the field most easily." See
Mecaphesa:
The anterior lateral eyes are a little larger than the anterior median eyes. When viewed from the front, and a little above, only six eyes are visible. The posterior laterals are facing sideways and backwards on tubercles that include the anterior laterals. Mecaphesa is also often (always?) hairy. See
