confrater group

As a group, the members of these species show minimal interspecific variation of external structures. One must examine and correlate variations of the aedeagus with those of the antennal club to fully appreciate the taxonomic significance of subtle integumental differences. In confrater group specimens the eighth antennomere is subquadrate (fig. 145); the aedeagus is slender (fig. 173) or flared at the base (fig. 112); the female pygidium is trigonal­scutiform (fig. 91) or broad­scutiform (fig. 88); and the tripartite humeral macula (fig. 56) is well developed. This group of South American species has been recorded from Guyana, Ecuador, Peru, Bolivia, and Brazil.
