          Abstract

          Fagineura Vikberg & Zinovjev, 2000 is recorded from China for the first time. Two species of Fagineura are described as new, F. flactoserrula sp. n. and F. xanthosoma sp. n. A key to the species of Fagineura worldwide is provided, now including four species. In addition, a simple phylogenetic analysis of Fagineura species is provided, based on sequences of the COI and NaK genes.

          World Catalog of Symphyta (Hymenoptera)

          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. Current taxonomic placement of genera and species and occurrence in zoogeographic regions are indicated. The list of names contains 31245 name combinations, variant spellings and family-group names. The authors attempted to consult all publications with taxonomic content referring to Symphyta that have appeared up to 31.12.2009. The 2960 cited references include all those that are known to contain original descriptions of taxa. Short biographical data and portraits of 168 symphytologists as well as images of representatives of extant sawfly taxa are included.

              Phylogenetics and evolution of host-plant use in leaf-mining sawflies (Hymenoptera: Tenthredinidae: Heterarthrinae).

              The habit of mining within leaves has evolved convergently in numerous plant-feeding insect taxa. Many leaf-mining groups contain a large number of species with distinct feeding preferences, which makes them highly suitable for studies on the evolutionary history of host-plant use and on the role of niche shifts in speciation. We aimed to clarify the origin, classification, and ecological evolution of the tenthredinid sawfly subfamily Heterarthrinae, which contains c. 150 leaf-mining species that collectively feed on over 20 plant genera around the world. For this, we reconstructed the phylogeny of representative heterarthrine species and diverse outgroups from the superfamily Tenthredinoidea on the basis of DNA sequence data collected from two mitochondrial (CoI and Cytb) and two nuclear (EF-1α and NaK) genes. Thereafter, we inferred the history of niche diversification within Heterarthrinae by plotting larval host-plant associations on the trees, and by contrasting a time-calibrated leaf-miner phylogeny with the phylogeny of their host plants. The results show that: (1) heterarthrine leaf-miners constitute a monophyletic group that arose from external-feeding blennocampine lineages within the Tenthredinidae c. 110-80 million years ago; (2) heterarthrines generally radiated well after their host taxa, and extant host-plant associations therefore result from a combination of host conservatism and occasional shifts among available plant taxa; and (3) diversification in Heterarthrinae apparently occurs by multiple mechanisms, including sympatric or allopatric ecological speciation, non-ecological allopatric speciation, and possibly allochronic speciation. Overall, both present and historical host-use patterns within the Heterarthrinae exhibit striking similarities to patterns found in co-occurring herbivore taxa. Copyright © 2012 Elsevier Inc.
