Suchentrunk and D. Willner, D. In this study we assess the phylogenetic position of the Mexican species relative to other forms within the genus and evaluate evolutionary affinities among the Mexican forms. Also of significance is the evidence found that morphologically divergent species in this region represent previously unrecognized adaptive radiations.

This research project produced the first molecular phylogeny for one of the largest Andean butterfly radiations, the genus Catasticta Butler,and employed that phylogeny to investigate critical questions about how evolution has proceeded in this important but poorly studied group. This phylogeny was then used to test several hypotheses about the timing of diversification, ancestral area of origin and wing pattern evolution in the genus.

The genus Catasticta was not recovered as monophyletic since C. Therefore, based on these results, I propose changes in the taxonomy to conserve Catasticta as monophyletic, including the synonymy of Archonias n. The time calibrated phylogenetic tree indicates that the most-recent whar ancestor occurred around Most of the speciation events at the species level have occurred between 5 to 12 Ma, and this period of time corresponds to the most important period of uplift of the Andes.

Complexity of ventral wing pattern, possibly used in camouflage of males feeding on river banks, increased significantly with elevation, while sexual importancs showed no clear pattern with elevation. The origin and uplift of the Andes have therefore played an important role in the speciation and diversification of these butterflies. Locality data points were compiled for all species of Catasticta and used to estimate the distributions of all species.

By overlaying species maps, the richness of Catasticta was also estimated, and this showed a clear pattern of high species richness in the Andes and in particular on the eastern slope, where as why do i get along better with guys reddit as 37 species can be found in some areas.

An important factor that limits the distribution of many of the species is elevation. This research sheds mopecular light on the origin and diversification of Catasticta, and suggests that revision of the species-level taxonomy thr a number of cases is still required, using molecular methods.
