Three species of Chilean leaf beetles were chromosomally analyzed. The endemic Araucanomela wellingtonensis displays a male meioformula of 13 + Xyp with 2n = 28 chromosomes and an asymmetric karyotype with two large autosome pairs and 12 medium/small pairs of autosomes and sex-chromosomes, a diploid number which had not been found among the other species of the subtribe Paropsina sensu lato studied to date. Strichosa eburata presents a meioformula of 11 + Xyp, 2n = 24 chromosomes, as occurs in…

A chromosomal analysis of four species of Chilean Chrysomelinae (Coleoptera, Chrysomelidae)
TLDR
Four species of Chilean leaf beetles in the subfamily Chrysomelinae have been cytogenetically analyzed and the karyotype of Henicotherus porteri is made of mostly small meta/submetacentric chromosomes, and that of Jolivetia obscura displays striking procentric blocks of heterochromatin at pachytene autosomic bivalents using conventional staining.
Cytogenetics, cytotaxonomy and chromosomal evolution of Chrysomelinae revisited (Coleoptera, Chrysomelidae) *
TLDR
A significant negative correlation between the haploid numbers and the asymmetry in size of karyotypes has been found from a large sample of 63 checked species of ten different genera, therefore the increases in haploid number are generally associated with a higher karyotype symmetry.

A Cytogenetic Study of the Leaf Beetle Genus Cyrtonus (Coleoptera, Chrysomelidae)
TLDR
The chromosomes of ten species of Cyrtonus and the genome sizes of six are surveyed and some possible factors implied in the rough chromosomal evolution are discussed in relation to a few other genera of the subfamily Chrysomelinae.
Karyology and Cytotaxonomy of the Genus Chrysolina Motschulsky (Coleoptera, Chrysomelidae)
TLDR
The taxonomic implications of these findings are discussed in relation with the current subgeneric classification of Chrysolina and principally that of the subgenera Colaphoptera, Sphaerochrysolina, Pleurosticha, Chalcoidea and Threnosoma.
The Cytogenetics and Cytotaxonomy of Clrrysolina Mots. and Oreina Chevr. (Coleoptera, Chrysomelidae, Chrysomelinae)
TLDR
The proposed chromosomal evolution of Chrysolina, mainly due to centric fissions and coupled to their host-plant shifts, is not contradicted by the molecular phylogeny even though the latter provides a better resolution.

Chromosome Numbers and Meioformulae of Chrysomelidae
TLDR
A large number of papers dedicated to the chromosomes of chrysomelids have been published in the last eleven years, increasing substantially the authors' karvological knowledge on this family of beetles, of which more than 70% belong to only three subfamilies.
Chromosomal analysis of Leptinotarsa and Labidomera species (Coleoptera: Chrysomelidae)
TLDR
No distinct correlation was evident when chromosome numbers and chiasma frequencies were compared with host plant association and geographic distribution patterns of Leptinotarsa species.

Distribution of Toxins in Chrysomeline Leaf Beetles: Possible Taxonimic Inferences
TLDR
A restricted number of genera are proposed based on a survey of the toxins produced by the pronotal and elytral defensive secretions in 114 chrysomeline species that may be useful in the building of a new and more natural classification of chrysOMeline leaf beetles.
