 Posts: 2604 | The head markings better match up with A. carolinensis (pronounced unbroken W, thick tapering occipital band). Another clue is the femora maculation. A. abnormis usually has either dark brown legs without obvious maculation or longitudinal dark stripes as opposed to the pale bands or blotches evidenced on this specimen. While a dark dorsal habitus is usually associated with abnormis, it is not a very dependable character. The other common species (lycorias) has head and leg markings that can look quite similar, but it has anal gills and usually a pale center with dark margins on the terga.
