Revision of the Griburius posticatus (Suffrian, 1866) species group (Coleoptera: Chrysomelidae: Cryptocephalinae).

Nine species of Griburius Haldeman, 1849 have been revised and critically discussed. One additional species, formerly included in Metallactus Suffrian, 1852, has been transferred to Griburius: Griburius tredecimpunctatus (Suffrian, 1866) comb. nov.

Revision of the Griburius scutellaris (Fabricius, 1801) species group (Coleoptera: Chrysomelidae: Cryptocephalinae).

Ten species of Griburius Haldeman, 1849, morphologically similar to each other, and some of their synonyms are revised, figured and discussed. Among them is G. scutellaris (Fabricius, 1801), the type species of Griburius.

Revision of the Metallactus taeniatellus species group (Coleoptera: Chrysomelidae: Cryptocephalinae).

The taeniatellus species group of Neotropical Metallactus Suffrian, 1866 of the subtribe Pachybrachina is defined and 10 species are revised and assigned to the group. Four of them already belonged to Metallactus. They are: Metallactus taeniatellus, Suffrian, 1866, M.

Revision of the Metallactus generosus species-group with a preliminary evaluation of the effectiveness of the endophallus morphology in distinguishing critical sibling species (Coleoptera: Chrysomelidae: Cryptocephalinae).

A taxonomic revision of the Metallactus generosus species-group is given in the present study. The complex is made up of three Neotropical species, two redescribed here and one new: Metallactus generosus Suffrian, 1866, M. argentinensis Jacoby, 1907 and M.

Revision of the Metallactus hamifer species-group (Coleoptera: Chrysomelidae: Cryptocephalinae).

The taxonomic revision of a group of Metallactus species, morphologically and chromatically close to M. hamifer Suffrian, 1866, is presented here. Before this revision, catalogues had been reporting 12 species attributable to this group.

Revision of the Metallactus kollari species-group with a new diagnosis of the genus (Coleoptera: Chrysomelidae: Cryptocephalinae).

The genus Metallactus has been controversial since its introduction due to the ambiguous nature of the original diagnosis. This has caused some confusion in the taxonomy of Neotropical Pachybrachina. In this work the morphology of endophallus, which is useful for the characterization of species groups in several groups of Coleoptera, including Cryptocephalinae, has been analyzed.

A comprehensive guide to the Argentinian case-bearer beetle fauna (Coleoptera, Chrysomelidae, Camptosomata).

Knowledge of Argentinian Camptosomata has largely remained static for the last 60 years since the last publication by Francisco de Asis Monrós in the 1950's. One hundred and ninety Camptosomata species (182 Cryptocephalinae and 8 Lamprosomatinae) in 31 genera are recorded herein from Argentina. Illustrated diagnostic keys to the subfamilies, tribes, subtribes and genera of Argentinian Camptosomata, plus species checklists and illustrations for all genera of camptosomatan beetles cited for each political region of Argentina are provided.

Barcoding Chrysomelidae: a resource for taxonomy and biodiversity conservation in the Mediterranean Region.

The Mediterranean Region is one of the world's biodiversity hot-spots, which is also characterized by high level of endemism. Approximately 2100 species of leaf beetle (Coleoptera; Chrysomelidae) are known from this area, a number that increases year after year and represents 5/6% of the known species. These features, associated with the urgent need to develop a DNA-based species identification approach for a broad spectrum of leaf beetle species, prompted us to develop a database of nucleotide sequences, with a solid taxonomic background, for all the Chrysomelidae Latreille, 1802 sensu latu inhabiting the Mediterranean region.

Colasposoma dauricum Mannerheim, 1849 an Asian species adventive to Piedmont, Italy (Coleoptera: Chrysomelidae: Eumolpinae).

Colasposoma dauricum Mannerheim, 1849, a species native to the Eastern Asia, is newly found in Piedmont-Italy. This discovery constitutes the first report of the species from Europe, as well as its first report from outside the original area. The general habitus of the species, the distribution in Italy based on the current knowledge, ecological notes and a reference cox1 gene sequences are reported in the present note.

Taxonomic remarks, phylogeny and evolutionary notes on the leaf beetle species belonging to the Cryptocephalus sericeus complex (Coleoptera: Chrysomelidae: Cryptocephalinae).

A cladistic analysis was carried out for a complex of 33 species of the genus Cryptocephalus that has been recognized for some time as monophyletic. 55 morphological adult characters have been used, with 119 character states. Analyses were performed using parsimony procedures as well as Bayesian inference.

Systematics of the weevil genus Mecinus Germar, 1821 (Coleoptera: Curculionidae). II. Phylogenetic analysis based on adult morphological characters and host plant information.

A phylogenetic analysis of all species belonging to the weevil genus Mecinus Germar, 1821 (Coleoptera: Curculionidae: Curculioninae: Mecinini) was carried out. Mecinus are exclusively Palaearctic and feed on Plantaginaceae belonging to the tribes Plantagineae and Antirrhineae. Based on a cladistic analysis of six outgroup and 47 ingroup taxa, and 31 adult morphological and three ecological characters, the monophyly of Mecinus appears strongly supported.

Pachybrachis holerorum (Coleoptera: Chrysomelidae: Cryptocephalinae), a new species from the Apennines, Italy, identified by integration of morphological and molecular data.

Pachybrachis holerorum n. sp. is described from the northern Apennines, Italy.

Immunocytochemical increased evidence of inducible nitric oxide synthase, tumor necrosis factor-alpha, and adrenocorticotropic hormone in human peritumoral lymph nodes.

In the current study, mesenteric and peritumoral lymph nodes surgically removed from patients with colon-rectum cancer were studied. Morphologic and immunocytochemical investigations demonstrated that mesenteric (control) and peritumoral lymph nodes of a same patient showed the same morphologic structure, but a different immunocytochemical pattern. Indeed, an increased immunoreactivity to anti-inducible nitric oxide synthase, anti-tumor necrosis factor-alpha, and anti-adrenocorticotropic hormone antibodies in the lymphatic tissue of peritumoral lymph nodes compared with mesenteric lymph nodes was observed.
