Unveiling of a cryptic Dicranomyia (Idiopyga) from northern Finland using integrative approach (Diptera, Limoniidae)
The subgenus Idiopyga Savchenko, 1987 is a northern hemisphere group of short-palped crane flies (Diptera, Limoniidae). In the current article we describe a new species, Dicranomyia (I.) boreobaltica Salmela sp.n., and redescribe the male and female post-abdomen of a closely related species, D. (I.)...

| Summary: | The subgenus Idiopyga Savchenko, 1987 is a northern hemisphere group of short-palped crane flies (Diptera, Limoniidae). In the current article we describe a new species, Dicranomyia (I.) boreobaltica Salmela sp.n., and redescribe the male and female post-abdomen of a closely related species, D. (I.) intricata Alexander. A standard DNA barcoding fragment of 5′ region of the cytochrome c oxidase I (COI) gene of the new species is presented, whilst the K2P minimum distances between the new species and 10 other species of the subgenus were found to range from 5.1 to 15.7 % (mean 11.2 %). Phylogenetic analyses (parsimony and maximum likelihood) based on COI sequences support the identity of the new species and its close relationship with D. (I.) intricata and D. (I.) esbeni (Nielsen). The new species is known from the northern Baltic area of Finland. The new species has been mostly collected from Baltic coastal meadows but an additional relict population is known from a calcareous rich fen that was estimated to have been at sea level circa 600-700 years ago. Dicranomyia (I.) intricata (syn. D. suecica Nielsen) is a Holarctic species, occurring in the north boreal and subarctic vegetation zones in Fennoscandia. |
