The speciose Brazilian Elateridae fauna is characterized by high karyotypic diversity, including one species (Chalcolepidius zonatus Eschscholtz, 1829) with the lowest diploid number within any Coleoptera order. Cytogenetic analysis of Conoderus dimidiatus Germar, 1839, C. scalaris (Germar, 1824,) C. ternarius Germar, 1839, and C. stigmosus Germar, 1839 by standard and differential staining was performed with the aim of establishing mechanisms of karyotypic differentiation in these species…

Cytogenetic Analysis of 3 Populations of Diabrotica speciosa (Chrysomelidae, Galerucinae): Constitutive Heterochromatin and Nucleolus Organizer Regions
TLDR
The diploid chromosome number, the morphology of chromosomes, the type of sex determination, the pattern of constitutive heterochromatin distribution and the chromosomes bearing the nucleolus organizer regions (NORs) were studied in specimens from 3 different Brazilian populations of D. speciosa.
C-bands on chromosomes of 32 beetle species (Coleoptera: Elateridae, Cantharidae, Oedemeridae, Cerambycidae, Anthicidae, Chrysomelidae, Attelabidae and Curculionidae).
TLDR
C-banding patterns of 32 beetle species from the families Elateridae, Cantharidae, Oedemeridae, Cerambycidae, Anthicidae, Chrysomelidae, Attelabidae and Curculionidae confirmed that most of the beetle species possess a small amount of heterochromatin and C-positive segments are weakly visible in pachytene stages and weakly or imperceptible in mitotic and meiotic metaphases.
Evidence for male XO sex-chromosome system in Pentodon bidens punctatum (Coleoptera Scarabaeoidea: Scarabaeidae) with X-linked 18S-28S rDNA clusters.
TLDR
The results obtained showed that a XO male/XX female sex determining mechanism - quite unusual among Scarabaeoidea - operates in the species investigated here, which suggests that heterochromatic DNA of P. punctatum is peculiar as compared with other types ofheterochromatin studied so far in other invertebrate taxa.
Cytogenetic analysis of Epicauta atomaria (Meloidae) and Palembus dermestoides (Tenebrionidae) with Xyp sex determination system using standard staining, C-bands, NOR and synaptonemal complex microspreading techniques.
TLDR
The mitotic and meiotic chromosomes of the beetles Epicauta atomaria and Palembus dermestoides were analysed using standard staining, C- banding and silver impregnation techniques and the chromosomal morphology, the C-banding pattern and the chromosome(s) bearing NORs (nucleolar organizer regions) were described.
Localization and activity of rDNA genes in tiger beetles (Coleoptera: Cicindelinae)
TLDR
The nucleolus does not seem to play a major role in the pairing and association of the multiple sex chromosomes during first meiotic prophase and metaphase and changes of location of NORs from the heterosomes to the autosomes have occurred within species of this genus, at least in species showing extensive karyotypic repatterning.
A study of the constitutive heterochromatin and nucleolus organizer regions of Isocopris inhiata and Diabroctis mimas (Coleoptera: Scarabaeidae, Scarabaeinae) using C-banding, AgNO3 staining and FISH techniques
TLDR
Analysis of constitutive heterochromatin revealed similar C-banding patterns for both species, showing pericentromeric and telomeric bands and diphasic chromosomes, and the X chromosomes of these species were found to be almost completely heterochromaatic.
C-bands and NORs on chromosomes in four species of the genus Trechus Clairv. (Coleoptera, Carabidae)
TLDR
Males of the examined species have the same pattern of silver precipitation during spermatogenesis and one silver dot on the end of two autosomes is visible in the mitotic stages, from the prophase to the prometaphase stage.

TLDR
No concordance between the pattern of r DNA sites and the phylogenetic relationships as based on morphological characters has been found, and changes altering the number of rDNA clusters seem to be uncoupled from the variation found in the chromosome number.
