At this stage we have to be satisfied with the recognition of the genus as a monophyletic group. The general structure displayed by all 14 species suggests that this group is not only monophyletic but forms one single genus. The 14 species form two distinct groups

At this stage we have to be satisfied with the recognition of the genus as a monophyletic group. The general structure displayed by all 14 species suggests that this group is not only monophyletic but forms one single genus. The 14 species form two distinct groups indicated by the symmetry of the aedeagus and the single correlated character found, the level of the clypeal margin (see p. 385). However, separate genera could not be allocated to these species groups, as one of them—comprising the plesiomorph species— apparently does not possess any apomorphic character states among the numerous characters studied. The two species groups are interpreted as two distinct evolutionary lineages within the genus. The first group, comprising the plesiomorph species, is a result. <- B Fig. 5. Lineage characters in the genus Colophon. A. Symmetrical aedeagus in the plesiomor- phic lineage, as in C. haughtoni Barnard. B. Asymmetrical aedeagus in the apomorphic lineage, as in C. primosi Barnard. C. Apical portion of penis with the non-rectractable inner sack as in C. primosi Barnard. D. Asymmetrical anal sternite in C. montisatris sp. nov., typical for the males of the apomorphic Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
