Unveiling of a cryptic Dicranomyia (Idiopyga) from northern Finland using integrative approach (Diptera, Limoniidae)

Abstract

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.

A molecular‐based identification resource for the arthropods of Finland

“…Despite initial skepticism from national funding agencies, FinBOL has delivered primary research results of the very type traditionally supported by them. Deliverables to date include insights into the protein structure of the barcode region (Pentinsaari et al, 2016), species interactions (Kaartinen et al, 2010; Mutanen, Ovaskainen, et al, 2020; Nyman et al, 2015; Rytkönen et al, 2019; Vesterinen et al, 2013, 2016), taxonomy (Boonstra et al, 2018; Haarto & Ståhls, 2014; Hausmann et al, 2013; Huemer et al, 2020; Huemer & Mutanen, 2015; Ivanov et al, 2018; Kirichenko et al, 2016; Kozlov et al, 2017; Landry et al, 2013; Landvik et al, 2013; Lee et al, 2020; Liston et al, 2019; Mutanen, Aarvik, Huemer, et al, 2012; Mutanen et al, 2012, 2013, 2015, 2016, 2020; Nieminen et al, 2018; Pentinsaari et al, 2014; Pentinsaari et al, 2014; Pilipenko et al, 2012; Pohjoismäki & Haarto, 2015; Pohjoismäki et al, 2016; Prous et al, 2016, 2020; Pykälä & Myllys, 2016; Salmela et al, 2014; Sihvonen et al, 2020; Ståhls et al, 2015; Tabell et al, 2019; van Nieukerken et al, 2012; Wikström et al, 2020; Wilson et al, 2011), phylogenetics (Heikkilä et al, 2014; Kaila et al, 2020; Karsholt et al, 2013), faunistics (Korpelainen & Pietiläinen, 2017; Paukkunen & Kozlov, 2015), biogeography (Huemer et al, 2014, 2018; Mutanen, Hausmann, et al, 2012; Salmela, 2012), methodology (Kekkonen et al, 2015; Korpelainen & Pietiläinen, 2...…”

Remarkable fly (Diptera) diversity in a patch of Costa Rican cloud forest: Why inventory is a vital science

“…Morphological studies are far more informative in understanding diversity than a species known only as a number. Barcoding, of course, is a powerful and useful tool in aiding species identity (including for inventories) and association of sexes and poorly known immatures with adults but we see it as just one useful instrument in a much larger toolbox (e.g., Dénes et al 2016;Germann et al 2010;Heller & Rulik 2016;Jürgenstein et al 2015;Kehlmaier & Assmann 2008;Petersen et al 2007;Salmela et al 2014;Ståhls & Haarto 2014;Stur & Borkent 2014;Stur & Ekrem 2015;Willassen 2005). Barcode clusters are hypotheses of species identity that need to be confirmed by taxonomists working with more complete sets of evidence.…”

Wing interference patterns are consistent and sexually dimorphic in the four families of crane flies (Diptera, Tipuloidea)

“…Crane flies vary in wing length from 3 to 36 mm and occupy a diverse set of habitats (Gelhaus and Podenine 2019) and act as a major food source in aquatic and riparian ecosystems (Baxter et al 2005;Gelhaus and Podeniene 2019). Furthermore, there is evidence of cryptic species within the superfamily (Ujvárosi et al 2010;Salmela et al 2014) and a lack of monophyly within the families (Petersen et al 2010). Tipuloidea is represented in the WIP literature from a single male specimen of Tipula (Savtshenkia) confusa van der Wulp, 1883 presented in .…”
