Species delimitation, classical taxonomy & genome skimming: a review of the ground beetle genus Lionepha (Coleoptera: Carabidae)By Maddison, DR & JS Sproul
Zoological Journal of the Linnean Society, XX, 1 - 46, 2020
The western North American genus Lionepha
is shown to contain at least 11 species through a combination of eight-gene species delimitation analyses and morphological study. In order to confirm the names of several species, we sequence DNA of primary types of several names, including a LeConte lectotype collected in the 1850s, using next-generation sequencing. We examine chromosomes of eight species, and show that all have 12 pairs of autosomesand an X0/XX sex-chromosome system. The following species are described as new: Lionepha australerasa, L. kavanaughi, L. lindrothi
and L. tuulukwa
. The name Lionepha erasa
is shown to belong to a relatively rare, western species ranging from Oregon through Alaska; the common, widespread species previously known as Lionepha erasa
now takes the name L. probata
. Bembidion chintimini, B. lindrothellus
and B. lummi
are synonymized with L. erasa
. We provide tools to identify specimens to species, including illustrations, diagnoses and distribution maps. DOI: 10.1093/zoolinnean/z1z167
Unifying systematics & taxonomy: Nomenclatural changes to Nearctic tiger beetles based on phylogenetics/morphology/life historyBy Duran, DP & HM Gough

Full title: Unifying systematics and taxonomy: Nomenclatural changes to Nearctic tiger beetles (Coleoptera: Carabidae: Cicindelinae) based on phylogenetics, morphology and life history.
Abstract: The taxonomy of Nearctic tiger beetles (Coleoptera: Carabidae: Cicindelinae) is reviewed in light of modern systematics research. Despite decades of published molecular phylogenies, the taxonomic nomenclature has not been formally updated since the 1950s. We generated a maximum likelihood phylogenetic tree based on three mitochondrial gene fragments (16S, COX3 and CytB) to address the placement of Nearctic taxa that were not included in recent studies; these species were historically contained within Cylindera Westwood, 1831, a polyphyletic genus. Here we describe Parvindela Duran and Gough, new genus, and propose 20 new combinations based on a plurality of data, including our topology, prior molecular phylogenetic studies, morphology and ecology: Apterodela unipunctata (Fabricius, 1775) new combination; Brasiella praecisa (Bates, 1890) new combination; Brasiella viridisticta (Bates, 1881) new combination; Cicindela amargosae (Dahl, 1939) new combination; Cicindela senilis (G.Horn, 1866) new combination; Cicindela willistoni (LeConte, 1879) new combination; Eunota californica (Menetries, 1883) new combination; Eunota circumpicta (LaFerte, 1841) new combination; Eunota fulgoris (Casey, 1913) new combination; Eunota gabbii (G. Horn, 1866) new combination; Eunota pamphila (LeConte, 1873) new combination; Eunota praetextata (LeConte, 1854) new combination; Eunota severa (LaFerte, 1841) new combination; Eunota striga (LeConte, 1875) new combination; Parvindela debilis (Bates, 1890) new combination; Parvindela celeripes (LeConte, 1848) new combination; Parvindela cursitans (LeConte, 1860) new combination; Parvindela terricola (Say, 1824) new combination; Parvindela nephelota (Bates, 1882) new combination; Parvindela lunalonga (Schaupp, 1884) new combination.
Range update for eight species of the subfamily Elaphrinae (Coleoptera: Carabidae) in Ontario's Far North & Nunavut, CanadaBy Fleming, KJ & Beresford, DV
The Coleopterists Bulletin 73(2): 433 - 439, 2019
ABSTRACT: Adults of eight species of beetles in the subfamily Elaphrinae (Coleoptera: Carabidae: Elaphrinae) were collected in the Far North of Ontario and on Akimiski Island, Nunavut, Canada. We found first records for Nunavut (territory) of seven species: Blethisa julii LeConte, 1863; Blethisa quadricollis Haldeman, 1847; Diacheila arctica (Gyllenhal, 1810); Elaphrus americanus Dejean, 1831; Elaphrus lecontei Crotch, 1876; Elaphrus clairvillei Kirby, 1837; and Elaphrus fuliginosus Say, 1830. Our record of one species, Elaphrus californicus Mannerheim, 1843, is a new range record for the province of Ontario.
