, a new leafhopper genus from northern North America, with a review of Oman (Hemiptera, Cicadellidae, Deltocephalinae).

The poorly known leafhopper species described as Deltocephalus (Laevicephalus) concinnus var. incisurus DeLong, 1926 previously had no accepted generic placement. It is here redescribed and placed in in the tribe Paralimnini, as (DeLong) Hamilton, 1987 is a junior of .

The genus in the Nearctic region (Hemiptera, Cicadellidae, Deltocephalinae).

The leafhopper genus contains grass-feeding leafhoppers in the deltocephaline tribe Paralimnini. The taxonomy of the genus in the Nearctic region has long been confused, with one to three distinct species recognized by different authors. Some populations have also been suggested to be adventive from Europe.

Hemiptera of Canada.

The Canadian Hemiptera (Sternorrhyncha, Auchenorrhyncha, and Heteroptera) fauna is reviewed, which currently comprises 4011 species, including 405 non-native species. DNA barcodes available for Canadian specimens are represented by 3275 BINs. The analysis was based on the most recent checklist of Hemiptera in Canada (Maw et al.

A revision of Boreantrops Kits & Marshall (Diptera: Sphaeroceridae: Archiborborinae).

Boreantrops Kits & Marshall is a recently described genus of flies in the family Sphaeroceridae. Species occur from Brazil and Bolivia north to northern Mexico, mostly in humid montane environments. Two species were included in the genus when originally described, B.

New records of bee flies (Diptera, Bombyliidae) from Cuatro Ciénegas, Coahuila, Mexico.

Forty one new records of species of Bombyliidae are reported for Coahuila in northeastern Mexico. Nine of these species are reported for the first time for the country. The specimens were collected in the Cuatro Ciénegas Basin and Sierra La Madera mountains during 2007-2013.

Phylogeny of the Archiborborinae (Diptera: Sphaeroceridae) based on combined morphological and molecular analysis.

The Archiborborinae is a diverse Neotropical subfamily of Sphaeroceridae, with many undescribed species. The existing generic classification includes three genera consisting of brachypterous species, with all other species placed in the genus Archiborborus. We present the first phylogenetic hypothesis for the subfamily based on morphological, molecular, and combined datasets.

Generic classification of the Archiborborinae (Diptera: Sphaeroceridae), with a revision of Antrops Enderlein, Coloantrops gen. nov., Maculantrops gen. nov., Photoantrops gen. nov., and Poecilantrops gen. nov.

The Archiborborinae comprise a diverse clade of flies in the family Sphaeroceridae. We here revise the generic classification, redefining the genus Antrops Enderlein and naming 5 new genera: Boreantrops gen. nov.
