Abstract
SummaryThe phylogeny of Phytosciara Frey, Prosciara Frey, Dolichosciara Tuomikoski (together forming Phytosciara sensu Tuomikoski), Lobosciara Steffan and Bradysia Winnertz was studied by parsimony analysis using the computer programs Pee‐Wee and NONA. The analysis was based on sixty‐four morphological characters from adult males, coded for thirty‐nine ingroup and two outgroup terminals. Three cladograms of the maximum fit (Pee‐Wee) and one of the minimum length (NONA) were obtained, some of them with polytomies. Many characters showed much homoplasy in the cladograms. The solution by the fittest cladograms was chosen as the main hypothesis of the phylogeny. Of the groups studied, only Lobosciara appeared monophyletic. The relationships of the taxa in their now revised monophyletic sense are: Dolichosciara + (Lobosciara + ((‘Prosciara’ fuscina group + ‘P’. vulcanata) + (‘P’. mima group + ((‘P’. perfida + (Bradysia + Phytosciara)) + Prosciara)))). Phytosciara Frey, Prosciara, Dolichosciara and Lobosciara in their revised concepts are regarded as genera.
