‘Retournement’ of the aedeagus in Curculionidae (Coleoptera, Curculionoidea) [PDF]
, 2013 Retournement or turning of the aedeagus about its longitudinal axis through about 180o during development is known in Chrysomeloidea (Coleoptera). This change in the orientation of the organ may be observed during the postembryonic development.

Insect Conservation and Diversity, EarlyView.In a given number of samples, grassland sward islets contain more species of arthropods than the surrounding sward. When corrected for abundance, there is no difference in species richness, suggesting that the effect of islets might purely be to concentrate arthropods. The community structure differences indicated by non‐metric multidimensional scaling

An interactive multi-entry key to the species of Megalostomis Chevrolat, with description of a new species from Paraguay (Chrysomelidae, Cryptocephalinae) [PDF]
, 2014 The main goal of this contribution is to release an interactive multi-entry key to all known species of the genus Megalostomis Chevrolat. This key constitutes a new tool created to aid the identification of the spe- cies of this diverse genus, which ...

Insect Molecular Biology, EarlyView.Comprehensive genome and stage‐specific transcriptomes reveal 14,637 genes in Listronotus oregonensis, advancing genetic insights into a key agricultural pest. Compared with related species, L. oregonensis exhibits reduced chemoreceptor gene families but expanded detoxification gene clusters, reflecting its narrow host range and adaptability.

Divergent defense strategies and niche partitioning in Cretaceous micro‐beetles
Journal of Systematics and Evolution, EarlyView.We report a new clambid beetle from mid‐Cretaceous Kachin amber, Scutacalyptus kolibaci gen. et sp. nov., characterized by a flattened body and explanate margins. Alongside spiny and conglobating clambid forms, this diversity reflects niche partitioning and varied antipredator strategies in the Cretaceous forest floor.

Oosagitta gen. nov. from tropical Africa, with revision of two species and description of four new species (Coleoptera: Chrysomelidae, Galerucinae) [PDF]
, 2013 After our taxonomic revision of Ootheca Chevrolat, 1837, and the description of Oothecoides Kortenhaus & Wagner, 2011 and Ootibia Kortenhaus & Wagner, 2012, it became clear that a further four galerucine species, closely related to the above named taxa ...
