The analysis is based on
morphological characters for 27 genera. Fourteen equally parsimonious trees were found. The
monophyly of the Mycetophilinae and the two tribes, Exechiini and Mycetophilini, is well
supported. Within the Exechiini, good support for the sister-group relationship of Exechia and
Exechiopsis was found, as was support for the inclusion of Cordyla in the tribe. The analysis
provides good resolution within the Mycetophilini, with Trichonta as the sister group of the
remaining taxa.1 aRindal, Eirik1 aSoli, Geir, E.

Recent studies have not shed much light on the intergeneric relationship within the tribe. Here the first attempt to resolve the phylogeny of the tribe Exechiini using molecular markers is presented. The nuclear 18S and the mitochondrial 16S, and cytochrome oxidase subunit I (COI) genes were successfully sequenced for 20 species representing 15 Exechiini genera and five outgroup genera. Bayesian, maximum parsimony and maximum likelihood analyses revealed basically congruent tree topologies and the monophyly of Exechiini, including the genus Cordyla, is confirmed. The molecular data corroborate previous morphological studies in several aspects. Cordyla is found in a basal clade together with Brachypeza, Pseudorymosia and Stigmatomeria. The splitting of the genera Allodiopsis s.l. and Brevicornu s.l. as well as the sistergroup relationship of Exechia and Exechiopsis is also supported. The limited phylogenetic information provided by morphological characters is mirrored in the limited resolution of the molecular markers used in this study. Short internal and long-terminal branches obtained may indicate a rapid radiation of the Exechiini genera during a short evolutionary period.1 aRindal, Eirik1 aSøli, Geir, E.
