The mandible palp being 2–3 articulate in this species can have many reasons, one of them being that the inner article on the left mandible palp was not seen due to its small size. When this is not proposed as the reason it is because smaller characters were easily seen from the same specimen, and even from the same parts, and because of the small size the pieces were translucent, and such it would be even less likely that an article was hidden under the main part of the mandible. It has also been shown in
