Bembidion (Ocydromus) terryerwini sp. nov. from Iran (Coleoptera, Carabidae, Bembidiina).

Bembidion (Ocydromus) terryerwinisp. nov. from Central Iran (Kerman and Yazd Provinces), described here, belongs to the decorum species group (Ocydromus Clairville, 1806). The new species is compared with the other taxa of this species group occurring in Iran and neighboring regions (Georgia, Armenia, Azerbaijan, Turkey, Iraq, Iran, South Pakistan, Afghanistan, and Turkmenistan).

Geographic and taxonomic notes, addenda and corrigenda on the subtribe Bembidiina Stephens, 1827 of the 2017 'Catalogue of Palaearctic Coleoptera' (Coleoptera, Carabidae, Bembidiina).

Some corrections to the section of subtribe Bembidiina of the Catalogue of Palaearctic Coleoptera, Vol. 1, together with geographic, systematic, and synonymic updates are reported and commented upon. The following five new synonymies are proposed (with junior synonym listed first): Bembidion (Peryphanes) dostali Kirschenhofer, 1984 = Bembidion (Peryphanes) sanatum Bates, 1883 syn. nov.; Bembidion (Terminophanes) pseudoconsumatum Kirschenhofer, 1984 = Bembidion (Terminophanes) sjoelanderi Jedlicka, 1965 syn. nov.; Bembidion (Asioperyphus) sapporense Jedlicka, 1951 = Bembidion (Politophanes) chloreum Bates, 1873 syn. nov.; Bembidion (Peryphus) torosiense Jedlicka, 1961 = Bembidion (Peryphus) subcostatum vau Netolitzky, 1913 syn. nov.; Sinechostictus (Sinechostictus) multisulcatus cariniger Korge, 1971 = Sinechostictus (Sinechostictus) multisulcatus (Reitter, 1890) syn. nov. Furthermore we confirm the following synonimies: Asaphidion weiratheri Netolitzky, 1935 = Asaphidion ganglbaueri J.Müller, 1921; Sinechostictus (Sinechostictus) effluviorum (Peyron, 1858) = Sinechostictus (Sinechostictus) tarsicus (Peyron, 1858). The following nine new combinations are proposed: Bembidion (Euperyphus) dimidiatum Ménétriés, 1832 comb. nov.; Bembidion (Peryphus) psuchrum Andrewes, 1922 comb. nov.; Bembidion (Plataphus) pseudolucillum Netolitzky, 1938 comb. nov.; Bembidion (Politophanes) chloreum Bates, 1873 comb. nov.; Bembidion (Politophanes) gotoense Habu, 1973 comb. nov.; Bembidion (Politophanes) shunichii Habu, 1973 comb. nov.; Bembidion (Politophanes) umeyai Habu, 1959 comb. nov.; Bembidion (Politophanes) yoshidai Morita, 2009 comb. nov.; Bembidion (Terminophanes) sjoelanderi Jedlicka, 1965 comb. nov. The species Bembidion psuchrum Andrewes, 1922 and Bembidion sanatum Bates, 1883 are here redescribed.

Phylogenetic relationships of the South American ground beetle subgenus Chilioperyphus Jeannel (Coleoptera: Carabidae: Trechinae: Bembidiini: Bembidion Latreille).

The boundaries and relationships of the ground beetle group Chilioperyphus Jeannel (a subgenus of the cosmopolitan genus Bembidion Latreille) are examined using DNA and morphological data. DNA sequence data from seven genes (six nuclear and one mitochondrial) indicates that Chiliopeiyphus (as newly defined) is monophyletic, and is related to the subgenera Antipetyphanes Jeannel and Plocanoperyphus Jeannel, within the South American Antiperyphanes Complex. Chilioperyphus includes two described species, B. iendocinum Jensen-Haarup and B. orregoi Germain. Beinbidion cassinense Roig-Juñent and Gianuca as well as Bembidion cuyanum Roig-Juñent and Scheibler, formerly placed in subgenus Chilioperyphus, are transferred to subgenus Antipetyphanes. Bembidion cuyanum is considered a junior synonym of B. hirtipes Jeannel. The male genitalia of Chilioperyphus is unique in having a very long flagellum that is folded twice, allowing it to fit much of its length within the walls of the median lobe. However, the brush sclerite and basal part of the flagellum are not contained within the median lobe, as they extend anterior to its base.

A new species of Bembidion ( Ecuadion) from Ecuador (Coleoptera, Carabidae, Bembidiini), with a key to members of the georgeballi species group.

A new species of ground beetle, Bembidion ricei, is described from the Andes mountains of Ecuador east of Quito. It belongs to the georgeballi species group of subgenus Ecuadion, and is most similar to Bembidion georgeballi. A key to the species of the group is provided.
