While working on an identification guide to the sawflies of Fennoscandia, we encountered numerous taxonomic problems, for some which present solutions. Dicrostema Benson, 1952 is a new synonym Phymatoceropsis Rohwer, 1916, and not congeneric with Paracharactus MacGillivray, 1908. Two species occurring in Europe are transferred . Dolerus aericepsellus Heidemaa Mutanen sp. nov. Heptamelus viitasa...

The Hymenoptera--ants, bees and wasps--represent one of the most successful but least understood insect radiations. We present the first comprehensive molecular study spanning the entire order Hymenoptera. It is based on approximately 7 kb of DNA sequence from 4 gene regions (18S, 28S, COI and EF-1α) for 116 species representing all superfamilies and 23 outgroup taxa from eight orders of Holome...

Recently we examined the phylogenetic utility of the large ribosomal subunit of mitochondrial DNA from the insect order Hymenoptera (Derr et al. 1992). That study included nucleotide sequence information for members of six superfamilies from the two hymenopteran suborders (Symphyta and Apocrita). After submitting the manuscript for publication we discovered an error regarding some of the sequen...
