The order Coleoptera is the most diversified group of the Class Insecta and is the largest group of the Animal Kingdom. This contribution reviews the Mesozoic insects and especially the coleopteran records from Argentina, based on bibliographical and unpublished materials (86 described species, 526 collected specimens). The material came from different geological units from the late Middle Triassic to the Late Triassic (Bermejo, Cuyo, and Malargüe basins) to the Middle-Late Jurassic and Early Cretaceous (Deseado Massif, Cañadón Asfalto, and San Luís Basin). The coleopteran record is composed of 29 described species with 262 collected specimens (isolated elytra) mainly represented by Triassic species and only four specimens recorded in Jurassic units, all of them currently unpublished. These fossil coleopterans provide fundamental information about the evolution of insects in the Southern Hemisphere and confirm the Triassic Argentinean insect deposits to be among the most important in the world.

New specimens of its type species from the Queensland Late Triassic (Norian) (~227–~208.5 Ma) fossil insect locality at Dinmore have revealed that the old and obscure Late Triassic genus Mesodiphthera Tillyard, 1919, from nearby Denmark Hill, is a tettigarctid cicada, the earliest record of the family and the oldest cicada. The genus is distinguished by the combined presence of three characters: the primary forks of R and M at about the same level, midway between the basal cell and the nodal line; RA2 with four or five terminal branches; and the inter-medial cross-vein backwardly inclined, running between M2 and M3. Of the three species originally ascribed to Mesodiphthera by Tillyard, only its type, M. grandis Tillyard, 1919, is retained in the genus. The other two species differ significantly from the type and are transferred to Tardilly gen. nov., which is similar to Mesodiphthera in the more or less aligned primary forks of R and M placed at about midway between the basal cell and the nodal line, and the backwardly inclined inter-medial cross-vein which runs between M2 and M3. It differs, however, in its smaller size, broader costal space, three-branched M3+4, and differently shaped CuA and CuA2. The new material, all of which is of M. grandis, provides a complete picture of the shape, colour and venation of its tegmen, whereas Tardilly prosboloides (Tillyard) comb. nov., 1922 and Tardilly dunstani (Tillyard) comb. nov., 1922 are still known only from their poorly preserved type specimens. Mesodiphthera and Tardilly exhibit a number of presumed plesiomorphies, viz the costal space much wider than the CuA cell, the basal cell strongly narrowed apically, and the post-nodal cross-vein series closer to the nodal line than the apex, which place it in the probable paraphyletic subfamily Cicadoprosbolinae. A more informed assessment of their relationships, however, must await a comprehensive analysis of the now 29 fossil genera of the family. The Tettigarctidae were the only cicadas of the Mesozoic and the discovery in the Triassic of Australia of Mesodiphthera and Tardilly clearly distinct from the 24 previously known Mesozoic genera, further demonstrates the family’s high degree of structural diversity, and emphasises its almost world-wide distribution in that Era.

AbstractMore than 30 fossil coleopteran (beetle) assemblages have been recorded from oxygen isotope stage 3 in northern Europe, comprising several hundred identified species. Using the mutual climatic range method for quantifying palaeotemperatures, these assemblages show that the climates of the times can be divided into two distinct interstadial types. One, a short phase of temperate/oceanic climate occurred between 43,000 and 42,000 14C yr B.P. when conditions were not much different from those of the present day. In spite of the temperate climate, trees did not colonize northwestern Europe at this time. Two, both before and after this temperate interlude there were phases of cold/continental climate during which summers were too cold for trees to grow and winters were of Siberian intensity. It is possible that periods of even colder conditions intervened from time to time between the interstadial but, because of the intensity of the cold, biological systems were so inhibited that no fossil evidence for them can be found in northern Europe. Evidence for them must be sought in the fossil records from the warmer parts of southern Europe or in the physical evidence in the Greenland ice cores.

Thanks solely to the labours of the late Oswald Heer, the fossil insect-fauna of Œningen is better known than that of any other locality or horizon in the world. But it is by no means so well known as it should be; for although Heer, in his latest enumeration of the specimens seen by him (Urwelt der Schweiz, 2e Aufl. 1879, p. 383), repeats precisely the same figures he has already given in 1861 (Recherches sur le climat du pays tert., p. 197), indicating in an interval of eighteen years no addition to his material (over 5000 specimens), his repeated additions to the number of species from that locality show that he had not fully worked over what he had. Indeed, thirty years ago, I arranged for exhibition in the Museum of Comparative Zoology at Cambridge a collection of nearly one hundred and fifty named species secured by Prof. Louis Agassiz from Heer, of which more than forty still remain undescribed; there are also a considerable number of merely nominal species enumerated by Heer in his Urwelt der Schweiz and elsewhere, duly catalogued by me in my Index to Fossil Insects (Bull. U. S. Geol. Surv. No. 71), but as yet neither described nor figured. In addition to this it may be noted that in the enumeration referred to above Heer mentions 543 species of beetles, while less than 270 nominal species have yet been published from Œningen, and only seven species from the Swiss Miocene, included in the enumeration.
