This species was first collected off Beaufort, North Carolina, by Day (1973: page 122, figure 16m-p).
I just noticed you put this under identification resources, probably because you are referencing a key. If you could mention in the text that it is included in a key (and include a link to where that key might be found online that would be great. It looks like it might be helpful to have a more detailed "Distribution" article because the one we have just says "Gulf of Mexico" which contradicts this! As always, a brief summary would be quite useful, too!
