The rove beetle fauna (Coleoptera: Staphylinidae) (excluding the subfamily Silphinae) of the PlioceneofWillershausen (Lower Saxony, North Germany) is reviewed based on the type and other material of previously described or reported taxa, as well as two new specimens. Six subfamilies are represented in the deposit, with two subfamilial assignments considered tentative: Aleocharinae?, Micropeplinae, Oxytelinae, Paederinae, Staphylininae? and Tachyporinae. Pliosyntomium Korge, 1967 syn.

Here, we report a fauna of immature aquatic dipterans from freshwater diatomites of the early Miocene Foulden Maar Fossil-Lagerstätte in southern New Zealand.
Methods: We document 30 specimens of immature dipterans, mostly pupae, and compare their external morphology to extant aquatic Diptera.
The first fossil limoniid fly from the Miocene Fossil-Lagerstätte of Foulden Maar in New Zealand is described on the basis of an isolated well-preserved wing. The specimen is tentatively attributed to a new species in the large extant genus , which is well diversified in the country. It is the second fossil record of this genus, the first one being an isolated wing from the Cretaceous Weald Clay Formation in the United Kingdom.

Particularly within the genus , many species exclusively occur on fresh and solidified resins or other exudates of vascular plants. In New Zealand, the only previously known species growing on plant exudate is , found on several endemic angiosperms in the family Araliaceae.

The flowers, although slightly smaller than the sole modern Australian species, A. bidwillii, contain pollen grains that are very like that taxon.

This study presents the first analysis of associations between plants and insects for the early Miocene Hindon Maar fossil lagerstätte, Otago, New Zealand. A total of 584 fossil angiosperm leaves representing 24 morphotypes were examined to determine the presence or absence of insect damage types.

Using flowers, fruits/cones and seeds from a well-dated (23 Ma) Miocene Lagerstätte in New Zealand, we show that across 23 families and 30 genera of forest angiosperms and conifers, reproductive features have remained constant for more than 20 Myr. Insect-, wind- and bird-pollinated flowers and wind- and bird-dispersed diaspores all indicate remarkable reproductive niche conservatism, despite widespread environmental and biotic change.

The anthers contain in situ pollen of the fossil palynomorph previously assigned to Diporites aspis Pocknall et Mildenh. (Onagraceae: Fuchsia L.
