. Nevertheless, the authors accommodated these specimens within the range of variability, mainly based on the measurements of avicularia and ovicells. In our opinion, observed differences, including the aspect of the frontal shield, are more relevant than the similarities, and we excluded them from the present species. Unfortunately, the poor preservation of the specimens prevents a complete description. The attribution of these specimens to the genus
