Abstract:
Thaumaleidae (seepage or madicolous midges) are a small family of aquatic Diptera. The common name refers to the larval habitat, which is always a thin film of vertical flowing water (i.e., madicolous). These habitats include waterfalls, rock-face seepages, splash zones around waterfalls and along cascading mountain streams. Thaumaleids are poorly known and rarely collected as a result of their habitat specificity. There are currently 8 recognized genera found worldwide except Antarctica. The monophyly of the family is well supported, however, generic concepts and relationships have never been rigorously tested. No phylogenies have been produced and the validity of several genera are questioned. The goal of this research is to produce the first comprehensive phylogeny for Thaumaleidae to ascertain generic relationships and test current generic concepts. Nucleotide sequences from three nuclear genes (Big Zinc Finger, Molybdenum Cofactor Sulfurase and Elongation Complex Protein 1) were acquired from at least one representative of each genus and several outgroup taxa, then analyzed phylogenetically using maximum parsimony, maximum likelihood and Bayesian analysis methods. Results support the recognition of 6 genera within two clades: a Northern Hemisphere clade and a Southern Hemisphere clade. Within the Northern clade, Trichothaumalea Edwards is sister to Thaumalea Ruthe (including Androprosopa Mik and Protothaumalea Vaillant). The Southern clade includes Afrothaumalea Stuckenberg as sister to Austrothaumalea Tonnoir (including Oterere McLellan) + [Neothaumalea Pivar, Moulton & Sinclair + Niphta Theischinger]. This is the first comprehensive phylogeny for Thaumaleidae and will act as a stable framework on which to base future studies upon.
