Until this study, Sennius Bridwell, 1946 included 60 species. As part of an ongoing revision of this genus, nomenclatural changes, synonymies, lectotype designations and corrections of misspelled names are presented, updating to a total of 68 species for this genus. One species is transferred from Sennius Bridwell, 1946 to Acanthoscelides Schilsky 1905, megacornis group: A. infractus (Johnson & Kingsolver, 1973) comb. n.. Eight species are transferred from Acanthoscelides Schilsky 1905 to Sennius Bridwell, 1946: S. aequinoctialis (Fåhraeus, 1839) comb. n., S. amazonicus (Pic, 1929) comb. n., S. batesii (Jekel, 1855) comb. n., S. diosanus (Pic, 1930) comb. n., S. notatopygus (Pic, 1930) comb. n., S. reductus (Pic, 1930) comb. n., S. transversesignatus (Fåhraeus, 1839) comb. n. and S. ventralis (Fåhraeus, 1839) comb. n.. One species is transferred from Megasennius Whitehead & Kingsolver 1975 to Sennius: S. muricatus (Sharp, 1885) comb. n.. One variety is elevated to species rank and transferred to Sennius: Sennius rufopygus (Pic, 1934) stat. n. comb. n. from Acanthoscelides carneofasciatus v. rufopygus Pic, 1934. New synonymies are proposed: The monotypic genus Megasennius Whitehead & Kingsolver 1975 is synonymized with Sennius as its type species is transferred to Sennius. Sennius batesii (Jekel, 1855) comb. n. = Bruchus subaenescens Pic, 1931 syn. n.; Sennius bicoloripes (Pic, 1930) = Bruchus bicoloripes var. jatayensis Pic, 1930 syn. n. and Bruchus bicoloripes var. indiversipes Pic, 1930 syn. n.; Sennius subdiversicolor (Pic, 1931) = Bruchus subdiversicolor var. innigripes Pic, 1931 syn. n.; Sennius transversesignatus (Fåhraeus, 1839) comb. n. = Bruchus carneofasciatus Pic, 1927 syn. n. and Bruchus carneofasciatus var. subapicalis Pic, 1930 syn. n.; and Sennius trinotaticollis (Pic, 1930) = Bruchus diversicollis Pic, 1930 syn. n. Lectotypes are designated for B. diversicollis, B. subdiversicolor var. innigripes, Sennius aequinoctialis, S. amazonicus, S. diosanus, S. reductus, S. rufopygus and S. subdiversicolor. Correct original spellings are noted for Bruchus batesii and B. lebasii Fåhraeus, 1839 in place of the incorrect subsequent spellings of Sennius batesi and Sennius lebasi.

The tribes Goniaderini Lacordaire, 1859 and Lupropini Lesne, 1926 within the tenebrionid subfamily Lagriinae Latreille, 1825 have previously been shown to be non-monophyletic by molecular phylogenetic analyses. The tribes and constituent genera are here reviewed and redefined morphologically. As part of tribal redefinitions, we establish Prateini with type genus LeConte, 1862.

Physciolagria Pic, 1930, a monotypic genus erroneously attributed to Tenebrionidae incertae sedis was found to be congeneric with the eurypine genus Lacconotopedilus Pic, 1935 (Mycteridae Blanchard, 1845). The taxonomic position and comparative morphology of Physciolagria are reassessed and discussed. A new genus-rank synonym (Physciolagria Pic, 1930 = Lacconotopedilus Pic, 1935 syn.

Morphogenesis is a tightly-regulated developmental process by which tissues acquire the morphology that is critical to their function. For example, epithelial cells exhibit different 2D and 3D morphologies, induced by distinct biochemical and biophysical cues from their environment. In this work, novel hybrid matrices composed of a Matrigel and synthetic oligo(ethylene glycol)-grafted polyisocyanides (PICs) hydrogels are used to form a highly tailorable environment.

We reviewed the species-level classification of Metriorrhynchina net-winged beetles to make the group accessible for further studies. Altogether, 876 valid species are listed in a checklist along with known synonyms, combinations, and distribution data. The compilation of geographic distribution showed that Metriorrhynchina is distributed mainly in the Australian region with very high diversity in the islands at the northern edge of the Australian craton, i.
