A paradox indeed: description of genitalia and clarification of the subtribal classification of Pachyonychis paradoxus Clark and Pachyonychus paradoxus Melsheimer (Coleoptera: Chrysomelidae: Galerucinae: Alticini).

Pachyonychis paradoxus Clark, 1860 and Pachyonychus paradoxus Melsheimer, 1847 are two species of Alticini whose strikingly similar names have led to significant confusion in the past. Recent study of American Oedionychina Chapuis, 1875 raised doubts about the validity of the subtribal placement of Pachyonychis Clark. Although general characteristics put this genus in Oedionychina, other features, especially the unusual shape of the pronotum, suggested that this monotypic genus would belong in Monoplatina Chapuis, 1875 instead.

Discovery of the first leaf litter inhabiting flea beetles in Brazil (Coleoptera: Chrysomelidae: Galerucinae) with description of two new genera and three new species.

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.

High turnover of Chrysomelidae (Coleoptera) species in semideciduous forest remnants in an agricultural landscape.

Differences in species composition between sites (β diversity) may be the result of spatial species replacement (turnover) or nestedness (subgroups of species from a more diverse site). In fragmented landscapes, the environmental factors that lead to these differences may be spatially structured. Herein, our objective is to determine if the β diversity of Chrysomelidae (Coleoptera) is due to turnover or nestedness and whether the observed pattern is due to loss of forest cover or spatial processes in forest remnants immersed in a matrix dominated by intense agricultural practice.

Chemical Composition and Food Potential of Pachymerus nucleorum Larvae Parasitizing Acrocomia aculeata Kernels.

Insect consumption as food is culturally practiced in various regions of the world. In Brazil, there are more than 130 species of edible insects registered, from nine orders, among which stands out the Coleoptera. The larva of the beetle Pachymerus nucleorum Fabricius, 1792, grows into the bocaiuva fruit (Acrocomia aculeata (Jacq.

Food Value of Mealworm Grown on Acrocomia aculeata Pulp Flour.

Insects have played an important role as human food throughout history, especially in Africa, Asia and Latin America. A good example of edible insects is the mealworm, Tenebrio molitor Linnaeus, 1758 (Coleoptera, Tenebrionidae), which are eaten in Africa, Asia, the Americas and Australia. This species is easily bred in captivity, requiring simple management.

Review of the West Indian genus Monotalla Bechyné (Coleoptera, Chrysomelidae, Galerucinae, Alticini) with description of five new species.

The West Indian genus Monotalla Bechyné is reviewed, redescribed and illustrated. Five new species are added: Monotalladominica sp. n.

Body size of Chrysomelidae (Coleoptera, Insecta) in areas with different levels of conservation in South Brazil.

Body size is correlated with many species traits such as morphology, physiology, life history and abundance as well; it is one of the most discussed topics in macroecological studies. The aim of this paper was to analyze the body size distribution of Chrysomelidae, caught with Malaise traps during two years in four areas with different levels of conservation in the Araucaria Forest, Paraná, Brazil, determining if body size is a good predictor of abundance, and if body size could be used to indicate environmental quality. Body size was considered the total length of the specimen from the anterior region of head to the apex of abdomen/elytron.
