Review of the Nearctic Salpinginae (Coleoptera: Salpingidae)

The Nearctic species of Salpinginae have not been reviewed for the last 92 years. Inconsistent worldwide treatments of salpingine genera and discordant classification schemes between Nearctic and Palearctic workers have created excessive taxonomic and nomenclatural confusion. We here revise the species from the Nearctic region by leveraging publicly available DNA barcoding data paired with examination of morphological features. We recognize three valid species and propose the following synonymies: Sphaeriestes virescens LeConte, 1850 (= Salpingus alternatus LeConte, 1859, Salpingus tibialis LeConte, 1866, Salpingus piscatorum Seidlitz, 1916, new synonyms); Salpingus viridiaeneus (Randall, 1838), restored combination (= Rhinomacer pallipes Boheman, 1858, synonym reinstated); and Salpingus elongatus Mannerheim, 1852, restored combination (= Rhinosimus (Cariderus) lecontei Blair, 1932, Rhinosimus (Cariderus) brachyrhynchus Hatch, 1965, new synonyms). Species treatments and an identification key are provided along with remarks on remaining worldwide classification issues.
