Chromosome numbers and sex chromosome systems of 154 previously unstudied Bembidion species are described. The genus is nearly uniform: males of 176 of 205 species are 2n=22+XY. Karyotypes are presented for 30 species. There is some variation among species in size of Y and size of autosomes. Within most species autosomes are subequal in size, and metacentric or submetacentric. Subterminal secondary constrictions and B chromosomes are reported from several species.The supertribe Trechitae… 
Species delimitation, classical taxonomy and genome skimming: a review of the ground beetle genus Lionepha (Coleoptera: Carabidae)
TLDR
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, and DNA of primary types of several names is sequence using next-generation sequencing.
Systematics of the North American beetle subgenus Pseudoperyphus (Coleoptera: Carabidae: Bembidion) based upon morphological, chromosomal, and molecular data
TLDR
Evidence for nuclear copies of cytochrome oxidase I (COI) in several species makes inference of the COI gene tree difficult, and is one reason that COI is not the gene of choice to identify Pseudoperyphus specimens, contrary to standard DNA barcoding protocols.
Absence asymmetry: The evolution of monorchid beetles (Insecta: Coleoptera: Carabidae)
TLDR
No function conclusively explains the ontogenetic loss of one testis in these carabid beetles, but it is tentatively suggested that testis loss is driven wholly by an interaction among the internal organs of these beetles, possibly due to selective pressure to maximize the comparatively large accessory glands found in these taxa.
Shards, sequences, and shorelines: two new species of Bembidion from North America (Coleoptera, Carabidae)
TLDR
This is the first known trio of species within Bembidion for which those genes provide no clear signal of species boundaries, and a coalescent species delimitation analysis reveals no notable structure within the complex.
A chromosome study of twenty species of Spanish carabid beetles (Coleoptera)
TLDR
Results corroborate that many tribes of Carabidae have a peculiar pattern of karyotypic evolution, causing a great diversity of chromosome number and/or chromosome morphology.
Characteristics of B‐chromosomes in Galetucella nymphaeae species complex (Coleoptera, Chrysomelidae)
TLDR
It seems that the shape of the distribution of B’s is created by their mitotic and meiotic properties, while the frequency of B-chromosomes in a population is determined by external factors, selection or random processes.
Chromosomal polymorphisms in Galerucella nymphaeae (L.) (Chrysomelidae, Coleoptera) in Finland
TLDR
B-chromosome and sex chromosome polymorphisms in 11 populations of Galerucella nymphaeae in Finland and one population in Sweden were studied and both seemed to be adaptively neutral.
MULTIPLE ORIGINS OF SEX CHROMOSOME FUSIONS CORRELATED WITH CHIASMA LOCALIZATION IN HABRONATTUS JUMPING SPIDERS (ARANEAE: SALTICIDAE)
TLDR
Origins of neo‐Y are correlated significantly with distal localization of chiasmata, supporting White's hypothesis that evolution of neo-Y systems is facilitated by looser pairing at meiosis, but an alternative (or contributing) explanation for the correlation is that X‐autosome fusions were selected to permit isolation of male‐favored alleles to the neo‐y chromosome, aided by distal chiasma limiting recombination.
Evidence of B-chromosomes in the karyotype of Barypeithes pellucidus Boheman 1834 (Coleoptera, Curculionidae, Entiminae) from Central Europe.
TLDR
B-chromosomes were observed in spermatogonial mitotic metaphases, meiotic metaphases I and II of Barpeithes pellucidus from one population in Slovakia and their staining intensity seems to be similar to that of the autosomes and sex chromosomes, respectively.

TLDR
The thirty-three chromosome numbers of Caraboidea reveal that these Coleoptera have a remarkable karyotypical heterogeneity, with species of ten genera show a neo-XY bivalent due to an X-autosome fusion.

TLDR
The karyotypes of fifty-three Spanish Caraboidea species belonging to the following families were studied, finding differences in the shape of the largest pair of autosomes (A pair) and the Y-chromosome are frequent among closely related species.
Natural hybridization in the coccinellid genus chilocorus
TLDR
A population of lady-bird beetles at the head of the Crowsnest River valley on the immediate east side of the Rocky Mountains has been sampled regularly over the years 1961 to 1964, finding meiotic pairing was virtually perfect but the trivalents in heterozygotes were frequently linearly aligned.

The North Island population of maorinum is distinct from the typical South Island form in having reduced microscrulpture on the elytra, and is here separated as levatum n.ssp.
Chromosome numbers of Coleoptera from Argentina

A list is presented containing data on chromosome numbers and sex determining mechanisms of 90 species of Argentina beetles, belonging to the families Staphylinidae, Meloidae, Elateridae, Tenebrionidae, Scarabaeidae, and Chrysomelidae.
Rates of karyotype evolution in placental mammals.
TLDR
The correlations between size, taxonomic diversity and rates of karyotype evolution are discussed in the light of results from theoretical models describing the spread of chromosome mutations in populations and particular attention is given to the role reproductive biology may play in influencing the rate of kARYotype evolution.
Chromosome numbers of Coleoptera1
TLDR
A complete revision of Makino's list of chromosome numbers of Coleoptera is warranted, since it is only through a logical grouping based on current concepts of taxonomic relationships that the full import of the cytological findings becomes evident.
The taxon pulse: a general pattern of lineage radiation and extinction among carabid beetles
TLDR
The realization that changes occur along ordered pathways and are repeated lineage after lineage in the history of major groups leads to the conclusion that evolution has boundaries in which it operates, and that perhaps there are some rules.

TLDR
In females only early prophase stages were observed, that are similar to those of the males, and the characteristics of this abnormal meiosis and its evolutionary and cytotaxonomic significance are discussed.
