what are the differences between these two species? the a.bicoloratum seems to be a little duller or tanner in coloration but it varies from picture to picture. i feel like there is some difference in the carapace, not in color (per se), but in shape. am i imagining things? and i know you're not supposed to base identification solely on coloration as that has little to do with the scientific identification. what would you say is the secret to telling these 2 species apart?
