Two new genera of flea beetles are described and illustrated: Brasilplatus Oliveira, Linzmeier Konstantinov new genus, monotypic, type species B. bahianus Oliveira, Linzmeier Konstantinov new species, and Tupiniquim Linzmeier, Oliveira Konstantinov new genus, containing two species, T. pronotalis Linzmeier, Oliveira Konstantinov new species and T. confusa Linzmeier, Oliveira Konstantinov new species and type species of the genus. These are the first described genera of flea beetles inhabiting leaf litter in Brazil. Brasilplatus belongs to the subtribe Monoplatina and is compared to other Monoplatina genera known to occur in leaf litter or moss cushions: Andersonaltica Linzmeier Konstantinov, 2012, Apleuraltica Bechyn, 1956 and Ulrica Scherer, 1962. Tupiniquim is unique among New World flea beetles, it allies cannot be immediately identified. Here it is compared to several New World and Old World genera.

Background: The univoltine leaf beetle (Curtis, 1837b) is native to the Palaearctic Region from Japan to western Europe.This species was previously evaluated as a potential biological control agent against invasive populations of the woodland weed (Bieb.) Cavara & Grande (Brassicaceae) in North America, but rejected because it could harm native and at-risk populations of Brassicaceae.

- The study focuses on the labrum, or upper lip, of adult flea beetles in the Chaetocnema genus, highlighting its under-researched role in classification and evolutionary relationships.
- Researchers aim to analyze the morphology of the labrum to create a standardized terminology and identify key features that could help distinguish different species and groups.
- The findings could contribute to better understanding species delimitation and the evolutionary history of leaf beetles within the Chrysomelidae family.

Background: RNA interference (RNAi) technology has emerged as a promising strategy for species-specific management of agricultural pests. However, the application of this technology has been significantly hindered by the instability of the interfering RNA molecules in the insect body after ingestion leading to variations in the susceptibility to the RNA triggers across different taxonomic groups of insects. Therefore, it is necessary to develop new approaches that will overcome these challenges associated with the use of RNAi-based insect pest management strategies.
