A. splendens has dark wings, dark legs, except the foreleg which is reddish-yellow. Reddish on the mouth parts. Hair on hind legs is deep golden and not too long, but quite thick. Watch out for the abdomen, it can sometimes look like sericeus, but the bands in between the segments are dark, in sericeus they are white.
A. texanus is the hairiest of them all, unmistakeable, especially on thorax sides, the hair is yellowish-white. Top of thorax is quite shiny. Legs hairs are a little darker, but quite short.
A. virescens female is unmistakeable as it is striped like the male."
