Abstract
In oribatid mites, porose organs (dermal glands) are expressed as two, mostly mutually exclusive, phenotypes: porose areas and saccules, both representing the cuticular components of these dermal glands. Patterns of expression of these phenotypes in abnormal individuals and rare species suggest that this may be a complex, non-Mendelian character, encoded by several genes (i.e., a polygenic trait). The evolution of porose areas and saccules, regarding the various modifications of their properties, such shape and position, appear to have greatly influenced the evolution and diversification of the megadiverse soil oribatid mite lineage, Poronota. We investigate the evolutionary dynamics of gain and loss of notogastral porose areas/saccules using a nearly complete phylogeny of the poronotic superfamily Galumnoidea (2 families, 56 genera and subgenera, 438 species, 459 terminals) in Maximum Parsimony and Maximum Likelihood frameworks. We note that the evolution of this trait is unidirectional, from porose areas to saccules. Based on this observation, we propose that the loss of porose areas is not likely to be down regulated by a third gene as suggested by the ?genetic switch? hypothesis. Furthermore, the presence of porose area (not saccules) is likely to be the ancestral condition. Overall, 16 characters associated with porose organs (18%) have evolved significantly more rapidly as compared to 73 other traits, indicating that they are under strong selection.
