Distribution (Fig. 178). Brazil (Amapá orig. New records: Goiás, Piauí and Roraima).
Discussion. Molineri & Emmerich (2010) described and diagnosed the species based only on males. We here give the first description of the female adult, but nymphs remain unknown. The female morphology of C. amapaensis coincides with that of the major species group proposed by Molineri & Emmerich (2010), but it may be separated from the other known females of this group (C. argentinus Esben-Petersen 1912 and C. major Needham & Murphy 1924) by the smaller size and darker coloration of C. amapaensis and also by details of the female sockets (Fig. 145).
