Full title: Are Miquihuana rhadiniformis Barr, 1982 and Pseudamara arenaria (LeConte, 1847) (Coleoptera, Carabidae) sphodrines? Phylogenetic analysis of data from next-generation sequencing of museum specimens resolves the tribal-group relationships of these enigmatic taxa.

Relevant to the N. American fauna, molecular and morphological data are presented to support the placement of Pseudamara in Zabrini, not Sphodrini.

An annotated checklist of ground beetles (Carabidae) in the state of Sonora, Mexico with new species & collection localities
By Spheley, D & T.R. Van Devender
Dugesiana 29(1): 41-137, 2021
Complete title: An annotated checklist of ground beetles (Insecta: Coleoptera: Carabidae) occurring in the state of Sonora, Mexico with descriptions of new species and notes about some collection localities.

ABSTRACT
An annotated checklist of ground beetles in the family Carabidae from the state of Sonora in Mexico is presented with notes including number of specimens examined, municipios, habitat, vegetation, elevation, and collection dates. The checklist includes 388 taxa, of which 270 are described taxa (included are 19 subspecies and 1 hybrid) and 118 are unnamed morphospecies, in 92 genera representing 35 tribes. Dot maps display where specimens were collected. Three new species are described, with corrected keys and images: Calathus mcclevei, new species (type locality: Mexico, Sonora, Municipality of Yécora, 10 km south of Yécora, ca. 28.278° N 108.926° W); Calathus tigrinus, new species (type locality: Mexico, Sonora, Municipality of Nacozari de García, Rancho El Tigre, 28.3 km (by air) WNW Bavispe, Sierra El Tigre, 30.58988° N 109.20811° W); and Amblygnathus balli, new species (type locality: Mexico, Sonora, Municipality of Fronteras, Rancho Capulín, 23.5 km (by air) WSW Fronteras, Sierra Buenos Aires, 30.76167° N 109.82361° W).

Western Hemisphere Zuphiini: descriptions of Coarazuphium whiteheadi (new species), Zuphioides (new genus), and classification

The article's main impact on BugGuide is that North American species previously belonging to Zuphium would be moved to genus Zuphioides. The latter Latinized name is treated as neuter and so the previous epithets under Zuphium remain unaffected.

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
ABSTRACT: 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.
