Revision of the genus Hormoserphus Townes, 1981 has shown that its type species, Proctotrupes clypeatus Ashmead, 1893 belongs to Oxyserphus Masner, 1961 (Oxyserphus clypeatus (Ashmead, 1893), comb. n. [= Hormoserphus transgressus Townes, 1981, syn. n.]) thus making Hormoserphus a junior synonym of the latter genus. Trachyserphus Kolyada, gen. n. is described to accommodate Oriental Trachyserphus segregatus (Townes, 1981), comb. n. (from Hormoserphus), Central American Trachyserphus defrictus (Townes, 1981), comb...

BACKGROUND: A revised checklist of the British and Irish Heloridae and Proctotrupidae (Proctotrupoidea) substantially updates the previous comprehensive checklist, dating from 1978. Country level data (i.e. occurrence in England, Scotland, Wales, Ireland and the Isle of Man) is reported where known. NEW INFORMATION: A total of three Heloridae and 39 Proctotrupidae (including only certainly recorded species) represents a 27% increase in the British list since 1978...

Disogmus rasnitsyni Kolyada & Perkovsky, sp. n. is described from a fossil inclusion of Late Eocene amber (Ukraine). The new species is most similar to Disogmus basalis (Thomson, 1857), in particular, in the shape of the tyloids and the general shortening of the segments of antennae, but distinctly differs from it and the other species of the genus by having tyloids on flagellar segments 2-4 compared to 3-6 and 4-7 in other species.

BACKGROUND: The order Hymenoptera (bees, ants, wasps, sawflies) contains about eight percent of all described species, but no analytical studies have addressed the origins of this richness at family-level or above. To investigate which major subtaxa experienced significant shifts in diversification, we assembled a family-level phylogeny of the Hymenoptera using supertree methods. We used sister-group species-richness comparisons to infer the phylogenetic position of shifts in diversification...
