Each cupule (small cup) comes in contact with the basal region of the corresponding coxa, specifically with its inflated supracondylar part, which shows a different texture and is covered by a very short, worn tomentum, mixed with longer setae along the margins. These cupules exist only in the female, while they are absent in the male, which shows similar P2-P4 coxae, with inflated and tomentose supra-condylar areas.

in the Homolidea remains unquestioned, this newly presented character does not permit to surely interpret it as a basal or advanced condition in this subsection. We will have to wait pending a more thorough investigation into the skeletal morphology and diversity in the Anomura, the Astacidea Latreille, 1802, and the Palinura Latreille, 1802. It is true that the relationships of the Archaeobrachyura (as a whole or partly) remain debatable.
