The total alignment included 58 taxa and 1704 bp. The family was recovered as monophyletic in parsimony and Bayesian analyses. In the Bayesian analysis, Mycetophilinae and its two tribes, Mycetophilini and Exechiini, were monophyletic with good statistical support. The subfamily Mycomyinae was found consistently in a sister-group relationship to Mycetophilinae. Gnoristinae was rendered paraphyletic, subtending Mycomyinae and Mycetophilinae. Within Gnoristinae, the genera Coelosia Winnertz, Boletina Staeger, Gnoriste Meigen group with Docosia Winnertz, usually considered to be a member of Leiinae. No support was found for the monophyly of the subfamilies Sciophilinae and Leiinae.1 aRindal, Eirik1 aSøli, Geir, E.

Eratomyia n. gen. is described based on a new species from Ecuador. Colonomyia brasiliana sp.n. and Colonomyia freemani sp.n. are described respectively from southern Brazil and Chile. The male of Cabamofa mira Jaschhof is described for the first time. A total of 64 terminal taxa and 137 transformation series (with 202 characters) were included in the data matrix, with a number of new features from thoracic morphology. Willi Hennig’s 1973 system for the higher Bibionomorpha was adopted using the name Mycetophiliformia for the Sciaroidea. The Mycetophiliformia are monophyletic. The family Cecidomyiidae appears as the sister group of the remaining Mycetophiliformia, followed by the Sciaridae. In the preferred topology, the Rangomaramidae appear as the group sister of a clade consisting of (Ditomyiidae + Bolitophilidae + Diadocidiidae + Keroplatidae) and of
(Lygistorrhinidae + Mycetophilidae). The topology within the Rangomaramidae is (Chiletrichinae subfam. n. (Heterotrichinae subfam. n. ((Rangomaraminae + Ohakuneinae subfam. n.))). Te Chiletrichinae include the genera Kenyatricha, Rhynchoheterotricha, Insulatricha, Chiletricha, and Eratomyia n. gen. Heterotrichinae and Rangomaraminae are monotypic. The subfamily Ohakuneinae includes Ohakunea, Colonomyia, Cabamofa, and Rogambara. The positions of Freemanomyia, Loicia, Taxicnemis, Sciaropota, Starkomyia, Anisotricha, Nepaletricha, and Sciarosoma are considered. Afrotricha might belong to the Sciaridae. The similarities used by many authors to gather the Sciaridae and Mycetophilidae in a clade are shown to be a combination of plesiomorphies and homoplasies.1 aAmorim, Dalton, de Sousa1 aRindal, Eirik  uhttp://www.online-keys.net/sciaroidea/2000_/Amorim&Rindal2007_Zootaxa_1535.pdf
