Abstract
Abstract A peculiar new lineage of sawflies (‘Symphyta’) is described and figured from a female beautifully preserved in Upper Cretaceous (Cenomanian) amber from northern Myanmar. Syspastoxyela rhaphidia Engel and Huang, gen. et sp. nov., shares many plesiomorphic features with the primitive Xyelidae, †Xyelotomidae, and †Xyelydidae such as enlarged and thickened first flagellomere succeeded by a series of thinner and shorter flagellomeres, absence of a transverse mesoscutal sulcus, multiple preapical spurs, and two protibial spurs among other traits. However, the new lineage has an apomorphically contracted forewing venation, lacks a subcostal vein, has a single marginal cell, and lacks crossvein 1r-rs, and thus it is segregated into a new family, Syspastoxyelidae Engel and Huang, fam. nov. The phylogenetic affinities of the new family are discussed and a position near Pamphilioidea or Pamphilioidea + Unicalcarida is advocated.

Potrerilloxyela menendezi gen. et sp. nov. from the Potrerillos Formation, Cuyo Basin, early Upper Triassic, Mendoza Province, Argentina is described. It is included in the living family Xyelidae and tentatively placed in Liadoxyelini of Xyelinae, which is otherwise known only from the Jurassic of Asia. This record is the first for Hymenoptera in the Triassic of the New World and provides new evidence about the close faunal connections between Laurasia and Gondwana during Mesozoic times. The phy...

Fossils of four insects and one larva from the Carboniferous Pennsylvanian epoch are described; these are very small relative to other known Palaeozoic-era insects, and reveal a previously unknown diversity of early eumetabolan insects, although the lineage radiated more successfully only after the mass extinctions at the end of the Permian period.

Abstract Novalyda cretacica, new genus and new species (“Symphyta”: Pamphilioidea: Xyelydidae), is described based on a unique male from the Early Cretaceous, Yixian Formation of northeastern China. The new species differs from others in the family by its relatively thick antenna, narrow costal cell, short first abscissa of Rs, sclerotization of the pterostigma. The species is the youngest occurrence of the family and extends the lineage into the Cretaceous period.

Amber from northern Myanmar has been commercially exploited for millennia, and it also preserves the most diverse palaeobiota among the worlds' seven major deposits of Cretaceous amber. Recent estimated ages vary from Albian to Cenomanian, based on palynology, an ammonoid, and Mesozoic insect taxa preserved within the amber. The burmite-bearing rock is sedimentaryand consists mainly of rounded lithic clasts (0.03w0.15 mm in diameter), with minor fragments of quartz and feldspar. Among the lithic...

The first comprehensive analysis of higher-level phylogeny of the order Hymenoptera is presented. The analysis includes representatives of all extant superfamilies, scored for 392 morphological characters, and sequence data for four loci (18S, 28S, COI and EF-1a). Including three outgroup taxa, 111 terminals were analyzed. Relationships within symphytans (sawflies) and Apocrita are mostly resolved. Well supported relationships include: Xyeloidea is monophyletic, Cephoidea is the sister group of ...

The first complete World Catalog of sawflies (Hymenoptera, suborder Symphyta) for over 100 years is presented. It contains references to the original descriptions and provides brief distributional data for 803 genera, 8353 species (123 with two or more subspecies) and 161 subspecies in addition to the nominal subspecies. 15245 proposed names are treated, including replacement names, infrasubspecific names and nomina nuda, of which only 22 could not be checked in the original publications.

 Premise of the study : It has been 8 years since the last comprehensive analysis of divergence times across the angiosperms. Given recent methodological improvements in estimating divergence times, refi ned understanding of relationships among major angiosperm lineages, and the immense interest in using large angiosperm phylogenies to investigate questions in ecology and comparative biology, new estimates of the ages of the major clades are badly needed. Improved estimations of divergence time...

Abstract The Burmese amber assemblage of Hymenoptera with its 47 constituent families is now the richest in Cretaceous. A collection of Burmite (Burmese amber) from the Hukawng Valley, Myanmar at the Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences was examined, revealing that Burmite inclusions contain a very highly diverse hymenopteran fauna with as many as ten families found new for the Burmese fossil assemblage. The mid-Cretaceous hymenopteran fauna of Burmese ambe...

A perfect flower in a mid-Cretaceous (early Cenomanian) Myanmar amber is described as Lijinganthus revoluta gen. et sp. nov. The fossil flower is actinomorphic and pentamerous, including calyx, corolla, stamens, and gynoecium. The sepals are tiny, while the petals are large and revolute. The stamens are dorsifixed, filamentous, and each has a longitudinally dehiscing bisporangiate anther. The gynoecium is in the centre of the flower, composed of three fused carpels with a stout style. Lijinganth...

Abstract A new family of basal apocritan wasps is established based on three new species discovered from the mid-Cretaceous Burmese amber and tentatively allied to the superfamily Stephanoidea. The family Myanmarinidae Zhang and Rasnitsyn fam. nov. contains one new genus Myanmarina Zhang and Rasnitsyn gen. nov., including three new species: Myanmarina lisu Zhang and Rasnitsyn sp. nov., Myanmarina kachin Zhang and Rasnitsyn sp. nov. and Myanmarina lahu Zhang and Rasnitsyn sp. nov. Comparisons are...

An unusual Cretaceous trap jaw ant is described from Burmese amber dated to the Late Cretaceous. Linguamyrmex vladi gen.n. sp.n. is distinguished by an unusual suite of morphological characters indicating specialized predatory behaviour and an adaptive strategy no longer found among modern ant lineages. The clypeus, highly modified as in other closely related haidomyrmecine hell ants, is equipped with a paddle-like projection similar to Ceratomyrmex. X-ray imaging reveals that this clypeal paddl...

Abstract A new fossil stick-insect (Phasmatodea) is described and figured from a male preserved in Cretaceous amber from Myanmar. Echinosomiscus primoticus Engel and Wang, gen. et sp. nov., is a robust, somewhat-compressed stick-insect bearing abundant acanthae over the head and body, and remarkably lacks an area apicalis on the tibiae. The species is described and assigned to a new, extinct subfamily of Phasmatidae s.l., as Echinosomiscinae Engel, subfam. nov. Brief remarks are made regarding t...
