“…The phylogenetic relationships of subgenus Nebriola have not been thoroughly examined, although some biogeographic hypotheses have been generated based on the species present distributions. Ledoux and Roux (2005) indicated the Nebriola clade is sister to the Boreonebria-Pseudonebria clade, and populated the Alps and Pyrenees from a Boreonebria ancestor. Pseudonebria exhibited similar geographic isolation in Asia.…”

“…It is hypothesised that Nebriola diverged from an ancient lineage of taxa related to Boreonebria and Pseudonebria. Species migrated into the Western Palearctic through a variety of dispersal mechanisms, such as to establish at higher altitudes, occasionally use caves, and as environmental temperatures raised, some species exhibited concurrent latitudinal (northwards) and elevational range increases (Ledoux and Roux, 2005).…”

“…Currently, the most widely accepted ground beetle subgenus Nebriola Daniel, 1903 (Coleoptera, Carabidae, Nebriinae, Nebria) (sensu Lorenz, 2005) nomenclature includes seven species (Daniel, 1903;Löbl and Smetana, 2003;Ledoux and Roux, 2005;Lorenz, 2005;Huber et al, 2010), plus an eighth species (Nebria praegensis Huber and Molenda, 2004, with an equivocal taxonomic status (Huber and Molenda, 2004;Huber et al, 2010).…”

“…The Nebria species of the subgenus Nebriola are restricted to extreme wet and cold habitat types. Nebria morula Daniel and Daniel, 1891, N. gosteliae Huber, 2010, and N. pictiventris Fauvel, 1888 show a very small, and probably relict geographic distribution, while the other four species of the subgenus (N. cordicollis Chaudoir, 1837, N. fontinalis Daniel and Daniel, 1890, N. lariollei Germiny, 1865, and N. laticollis Dejean, 1826 are more widely distributed in the central western Alps and Pyrenees, but are polytypic and exhibit high intra-specific variability (Ledoux and Roux, 2005).…”

“…Nebriola species are characterised by fairly homogeneous external morphology, which to date has resulted in a high level of uncertainty in taxonomic classification (Jeannel, 1941;Bänninger 1949-50;Bari, 1971;Focarile, 1976;Focarile and Casale, 1978;Casale and Vigna Taglianti, 1993;Bisio, 1998;Löbl and Smetana, 2003;Vigna Taglianti, 2005;Lorenz, 2005;Ledoux andRoux, 2005, Huber et al, 2010). Species identification is often difficult; therefore it has been hypothesised that several distinct entities remain unrecognised in Nebriola, i.e.…”

The European Alps support several ground beetle Nebria (Nebriola) species, which are morphologically similar. A study conducted on a Nebriola population located between the Eastern Pennine and Western Lepontine Italian Alps revealed the presence of two species, Nebria (Nebriola) cordicollis and N. (Nebriola) gosteliae, and some individuals that possibly represented an unknown taxonomic unit (UTU). Therefore, to further elucidate and characterise the morphological units at the site, we completed a comparative analysis using geometric morphometrics applying the semilandmarks approach. We examined the pronotum, the right elytron, and the median lobe of aedeagus. The quantitative analysis evaluated the overall variation in shape and size of the three structures. Results supported the hypothesised presence of three distinct groups of individuals, with different morphologies for the anatomical traits examined. The pronotum and median lobe of aedeagus exhibited more marked differences among the groups, while the right elytron showed reduced differentiation. These results confirmed that the three groups were separate taxa, and were therefore correctly classified. Based on our findings, we considered the UTU a new species, which is here described as Nebria (Nebriola) casalei sp. nov.

Phylogeny of the supertribe Nebriitae (Coleoptera, Carabidae) based on analyses of DNA sequence data

The phylogeny of the carabid beetle supertribe Nebriitae is inferred from analyses of DNA sequence data from eight gene fragments including one nuclear ribosomal gene (28S), four nuclear-protein coding genes (CAD, topoisomerase 1, PEPCK, and wingless), and three mitochondrial gene fragments (16S + tRNA-Leu + ND1, COI (“barcode” region) and COI (“Pat/Jer” region)). Our taxon sample included 264 exemplars representing 241 species and subspecies (25% of the known nebriite fauna), 39 of 41 currently accepted genera and subgenera (all except Notiokasis and Archileistobrius), and eight outgroup taxa. Separate maximum likelihood (ML) analyses of individual genes, combined ML analyses of nuclear, nuclear protein-coding, and mitochondrial genes, and combined ML and Bayesian analyses of the eight-gene-fragment matrix resulted in a well-resolved phylogeny of the supertribe, with most nodes in the tree strongly supported. Within Nebriitae, 167 internal nodes of the tree (out of the maximum possible 255) are supported by maximum-likelihood bootstrap values of 90% or more. The tribes Notiophilini, Opisthiini, Pelophilini, and Nebriini are well supported as monophyletic but relationships among these are not well resolved. Nippononebria is a distinct genus more closely related to Leistus than Nebria. Archastes, Oreonebria, Spelaeonebria, and Eurynebria, previously treated as distinct genera by some authors, are all nested within a monophyletic genus Nebria. Within Nebria, four major clades are recognized: (1) the Oreonebria Series, including eight subgenera arrayed in two subgeneric complexes (the Eonebria and Oreonebria Complexes); (2) the Nebriola Series, including only subgenus Nebriola; (3) the Nebria Series, including ten subgenera arrayed in two subgeneric complexes, the Boreonebria and Nebria Complexes, with the latter further subdivided into three subgeneric subcomplexes (the Nebria, Epinebriola, and Eunebria Subcomplexes)); and (4) the Catonebria Series, including seven subgenera arrayed in two subgeneric complexes (the Reductonebria and Catonebria Complexes). A strong concordance of biogeography with the inferred phylogeny is noted and some evident vicariance patterns are highlighted. A revised classification, mainly within the Nebriini, is proposed to reflect the inferred phylogeny. Three genus-group taxa (Nippononebria, Vancouveria and Archastes) are given revised status and seven are recognized as new synonymies (Nebriorites Jeannel, 1941 and Marggia Huber, 2014 = Oreonebria Daniel, 1903; Pseudonebriola Ledoux & Roux, 1989 = Boreonebria Jeannel, 1937; Patrobonebria Bänninger, 1923, Paranebria Jeannel, 1937 and Barbonebriola Huber & Schmidt, 2017 = Epinebriola Daniel & Daniel, 1904; and Asionebria Shilenkov, 1982 = Psilonebria Andrewes, 1923). Six new subgenera are proposed and described for newly recognized clades: Parepinebriola Kavanaugh subgen. nov. (type species: Nebria delicata Huber & Schmidt, 2017), Insulanebria Kavanaugh subgen. nov. (type species: Nebria carbonaria Eschscholtz, 1829), Erwinebria Kavanaugh subgen. nov. (type species Nebria sahlbergii Fischer von Waldheim, 1828), Nivalonebria Kavanaugh subgen. nov. (type species: Nebria paradisi Darlington, 1931), Neaptenonebria Kavanaugh subgen. nov. (type species: Nebria ovipennis LeConte, 1878), and Palaptenonebria Kavanaugh subgen. nov. (type species: Nebria mellyi Gebler, 1847). Future efforts to better understand relationships within the supertribe should aim to expand the taxon sampling of DNA sequence data, particularly within subgenera Leistus and Evanoleistus of genus Leistus and the Nebria Complex of genus Nebria.
