| Description | A hypothesis of phylogenetic relationships of mainly Holarctic Anthomyzidae based on multigene analysis of combined mitochondrial + nuclear gene markers is compared with those of previously published cladistic analyses of morphological characters with the aim to elucidate affinities of phylogenetically unsettled taxa. The placement of Fungomyza Roháček, 1999, Amygdalops Lamb, 1914 + Typhamyza Roháček, 1992 and Quametopia Roháček & Barber, 2011 + Paranthomyza Czerny, 1902 proved to be well supported by molecular data but are inconsistent with those suggested by morphological data analyses, therefore demanding further phylogenetic study. In other groups, the relationships recognized by multigene molecular analysis are in agreement with previous or subsequent morphological examination: the Mumetopia nigrimana group is postulated as the closest ally of Stiphrosoma Czerny, 1928 and hence needs to be excluded from Mumetopia Melander, 1913; intrageneric relationships of Arganthomyza Roháček, 2009 and allies revealed that Ischnomyia spinosa Hendel, 1918 is, in fact, a species of Arganthomyza and that the concept of the genus Ischnomyia Loew, 1863 has to be redefined; Epischnomyia Roháček, 2006 proved to be closest to Anthomyza Fallén, 1810. The placement of the genera Anagnota Becker, 1902, Carexomyza Roháček, 2009, Cercagnota Roháček & Freidberg, 1993 and Santhomyza Roháček, 1984 have not been resolved either by molecular or morphological analyses and their sister groups remain unknown. The new molecular evidence provides new insight into the phylogeny of Anthomyzidae, but like morphology, fails to resolve some key nodes, suggesting that new studies using both sources of information will be necessary to fully reconstruct the history of the family. |
