(2015): Exploring patterns of variation within the central-European Tephroseris longifolia agg.: karyological and morphological study. – Preslia 87: 163–194. Tephroseris longifolia agg. is an intricate complex of perennial outcrossing herbaceous plants. Recently, five subspecies with rather separate distributions and different geographic patterns were assigned to the aggregate: T. longifolia subsp. longifolia, subsp. pseudocrispa and subsp. gaudinii predominate in the Eastern Alps; the distribution of subsp. brachychaeta is confined to the northern and central Apennines and subsp. moravica is endemic in the Western Carpathians. Carpathian taxon T. l. subsp. moravica is known only from nine localities in Slovakia and the Czech Republic and is treated as an endangered taxon of European importance (according to Natura 2000 network). As the taxonomy of this aggregate is not comprehensively elaborated the aim of this study was to detect variability within the Tephroseris longifolia agg.

ZooKeys 441: 291–303. doi: 10.3897/zookeys.441.7586 Abstract A checklist of the Agromyzidae (Diptera) recorded from Finland is presented. 279 (or 280) species are currently known from the country. Phytomyza linguae Lundqvist, 1947 is recorded as new to Finland. Keywords Checklist, Finland, Diptera, biodiversity, faunistics Introduction The Agromyzidae are called the leaf-miner or leaf-mining flies and not without reason, although a substantial fraction of the species feed as larvae on other parts of living plants. While Agromyzidae is traditionally placed in the superfamily Opomyzoidea, its exact relationships with other acalyptrate Diptera are poorly understood (see for example Winkler et al. 2010). Two subfamilies are recognised within the leaf-mining flies: Agromyzinae and Phytomyzinae. Both are now recognised as natural groups (Dempewolf 2005, Scheffer et al. 2007). Unfortunately the genera are not as well defined: at least Ophiomyia, Phy- toliriomyza and Aulagromyza are paraphyletic in DNA sequence analyses (see Scheffer et al.
