The first mastotermitid termite from Africa is described and figured from wing fragments recovered from the early Miocene (22–21 Ma) deposits of the Mush Valley, Amhara Region, central Ethiopia. Mastotermes aethiopicus new species is the second fossil termite recorded from Africa and expands the known paleo-distribution of the genus from tropical North America and Europe into northeastern Africa during the Miocene. Mastotermes aethiopicus is distinguished from the living M. darwiniensis Froggatt and other Neogene species of the genus, and comments are provided regarding the occurrence of this genus in the tropical fauna of Miocene Ethiopia.

Among weevils of the subfamily Baridinae (548 extant genera and ca. 9,000 species), unique prosternal horns and associated sheaths have evolved independently multiple times. These structures are utilized in a unique form of male-male aggression in which males push, rather than overturn as in most other horned beetles, their competitor. Herein we report the first fossils of male Baridinae exhibiting such prosternal horns. Two males recovered from the middle Eocene Green River Formation in northwestern Colorado serve to provide a minimum age (at ca. 47 million years old) for both the origin of horns and its associated form of male-male combat in Baridinae.

The article reports on the examination of Cretaceous termites in an effort to reconstruct Isoptera phylogeny and early evolution. The authors discussed the features characteristic of the alates of Mastotermitidae, including the foreleg with at least three terminal spurs, hind leg with four terminal spurs and large forewing scale.

The Middle Eocene (Lutetian) bee faunas of Eckfeld and Messel, Germany are revised. In addition to the previously known Electrapis electrapoides (Lutz), five additional species are recognized. Four new species of the Electrapini (Apidae: Apinae) are described: Electrapis micheneri Wappler and Engel, E. prolata Engel and Wappler, Protobombus pristinus Wappler and Engel, and P. messelensis Engel and Wappler. In addition, the new genus Pygomelissa Engel and Wappler is proposed for Pygomelissa lutetia Engel and Wappler new species, which cannot presently be classified into any tribe of the Apidae. The tribe Megachilini (Megachilidae: Megachilinae) is also recorded from Eckfeld but in the absence of any body fossil. Megachilines include the leaf-cutter bees (Megachile) and from the occurrence of the distinctive semicircular damage they produce in leaves, we conclude that such bees were also present in the fauna. The bee fauna is compared with that of the contemporaneous Baltic amber. As with Baltic amber, the majority of bee specimens are from the advanced eusocial lineages of the corbiculate Apinae. Lastly, comments are made on the phylogenetic and paleobiological significance of the faunas. [ABSTRACT FROM AUTHOR]

A fossil halictine bee from Early Eocene, Okanagan Highlands deposits of Quilchena, British Columbia, Canada, is described and figured. Halictus? savenyei sp.nov, is distinguished from other Tertiary halictines as well as modern bees. The specimen is the second oldest body fossil of a bee yet discovered and the first fossil bee from Canada. The antiquity of Halictidae and of bees in general is briefly commented upon.

The article presents a speech delivered by scientist Michael S. Engel, recipient of the Paleontological Society's 2008 Schuchert Award, on October 6, 2008 in which he thanked David Grimaldi for presenting the award to him and the society for giving the award and discussed his research study on the evolutionary history of a lineage of tiny and brilliant metallic green bees which he considered as one of his vital contributions to paleontology.

Representatives of the family Strephocladidae have been considered as fossil relatives (i.e., stem-group) of Mantodea (mantises) based on characters of the forewing morphology. Here we describe new specimens from the Wellington Formation that we assign to the strephocladid species Homocladus grandis Carpenter, 1966. The range of morphological variation exhibited by the new material, in addition to wing morphology variability documented in extant mantises and roaches, suggest that H. ornatus Carpenter, 1966 and Paracladus retardatus Carpenter, 1966, reported from the same formation, are new junior subjective synonyms of H. grandis. We describe the first hind wing for this species based on a well-preserved specimen. It exhibits a combination of character states unique to dictyopteran insects. [ABSTRACT FROM AUTHOR]

The first definitive fossil species of the rove beetle (Staphylinidae) subfamily Phloeocharinae is described and figured from a single individual preserved in Late Cretaceous (Turanian) amber from New Jersey. The species is representative of the extant genus Phloeocharis Mannerheim and is described as Phloeocharis agerala Chatzimanolis, Newton, and Engel, new species. The specimen was imaged using traditional light microscopy as well as synchrotron propagation phase contrast microtomography, permitting a detailed examination of otherwise difficult to observe features. Examination revealed remarkable homogeneity across many characters with those of extant relatives, highlighting considerable morphological stasis in the genus over the last 90 million years.
