New records of Cassidinae and Cerambycidae (Coleoptera: Chrysomeloidea) from Baturité Massif, Brazil, with the description of a new species of Charidotis (Coleoptera: Chrysomelidae: Cassidinae).

The Baturité massif, situated in Ceará state's central hinterland, is one of the largest humid mountain ranges in the Brazilian semi-arid region. Flora and vertebrate surveys have been conducted in the region, revealing endemic species, as well as a combination of fauna and flora from neighboring biomes, the Atlantic and Amazon rainforests. However, invertebrate inventories have been scarce, leaving a significant portion of the region's biodiversity unexplored.

A new species in the tortoise-beetle genus Dorynota s. str. Chevrolat (Coleoptera: Chrysomelidae: Cassidinae: Dorynotini) from Brazil.

A new species Dorynota phoenix Simões and Sekerka, new species is described and figured from Mato Grosso state of Brazil. The new species belongs to the D. monoceros species-group and is compared to morphologically similar taxa.

The First Eight Mitogenomes of Leaf-Mining Beetles (Coleoptera: Chrysomelidae: Cassidinae) Shed New Light on Subgenus Relationships.

The taxonomic classification of , a large genus of leaf-mining beetles, is problematic because it is currently based on morphology alone. Here, the first eight mitochondrial genomes of species, which were used to construct the first molecular phylogenies of this genus, are reported. The lengths of the eight mitogenomes range from 17,189 bp to 20,363 bp.

Climate shapes the spatiotemporal variation in color morph diversity and composition across the distribution range of Chrysomela lapponica leaf beetle.

Color polymorphism offers rich opportunities for studying the eco-evolutionary mechanisms that drive the adaptations of local populations to heterogeneous and changing environments. We explored the color morph diversity and composition in a Chrysomela lapponica leaf beetle across its entire distribution range to test the hypothesis that environmental and climatic variables shape spatiotemporal variation in the phenotypic structure of a polymorphic species. We obtained information on 13 617 specimens of this beetle from museums, private collections, and websites.

Studies on the genus Chrysodema (Coleoptera: Buprestidae: Chrysochroinae) part I.

Subgeneric classification of Chrysodema Laporte de Castelnau Gory, 1835 is revised and following synonymy is established: Chrysodema=Cyalithoides Fisher, 1922 syn. nov.; Pseudochrysodema Saunders, 1874=Leganya Hołyński, 1994 syn.

Revision of the tribe Cryptonychini (Coleoptera: Chrysomelidae: Cassidinae) of New Caledonia.

New Caledonian members of the tribe Cryptonychini are revised. The tribe is represented by eigth genera and 23 species, all but one endemic to New Caledonia. A new genera Paratorquispa gen.

An annotated checklist of the leaf beetles (Coleoptera, Chrysomelidae) from El Salvador, with additions from the Bechyné collection in the Royal Belgian Institute of Natural Sciences.

A checklist of the species of leaf beetles (Coleoptera: Chrysomelidae) of El Salvador is presented based on data from literature and a digitization project of the Bechyné collection of the Royal Belgian Institute of Natural Sciences (RBINS). The RBINS collections contain a total of 2797 individual chrysomelid specimens from El Salvador, sorted into 89 species and 132 genera. In total, the current checklist contains 420 species, of which 33 are new records for El Slavador from the Bechyné collection.
