When details matter: Integrative revision of Holarctic Coelophthinia Edwards (Diptera, Mycetophilidae), including mapping of its mitogenome, leads to the description of four new pseudocryptic species

The small genus Coelophthinia Edwards, 1941 of the subfamily Gnoristinae (Diptera, Mycetophilidae) is so far known to harbour four species from Palaearctic, Nearctic and Neotropical Regions. Extensive DNA barcoding fungus gnats family Mycetophilidae through International Barcode Life project (iBOL) have initiated integrative studies resulting in taxonomic upgrades a better understanding many their delimitation. opportunity was also taken describe mitogenome member for first time. give evidence splitting European C. thoracica into three different species.
