Gall formation is a specialised form of phytophagy that consists of abnormal growth of host plant tissue induced by other organisms, principally insects and mites. In the mainly parasitoid wasp subfamily Doryctinae, gall association, represented by gall inducers, inquilines and their parasitoids, is known for species of seven genera. Previous molecular studies recovered few species of six of these genera as monophyletic despite their disparate morphologies. Here, we reconstructed the evolutionary relationships among 47 species belonging to six gall-associated doryctine genera based on two mitochondrial and two nuclear gene markers. Most of the Bayesian analyses, performed with different levels of incomplete taxa and characters, supported the monophyly of gall-associated doryctines, with Heterospilus (Heterospilini) as sister group. Percnobracon Kieffer and Jörgensen and Monitoriella Hedqvist were consistently recovered as monophyletic, and the validity of the monotypic Mononeuron was confirmed with respect to Allorhogas Gahan. A nonmonophyletic Allorhogas was recovered, although without significant support. The relationships obtained and the gathered morphological and biological information led us to erect three new genera originally assigned to Psenobolus: Ficobolus gen.n. (F. paniaguai sp.n. and F. jaliscoi sp.n.), Plesiopsenobolus gen.n. (Pl. mesoamericanus sp.n., Pl. plesiomorphus van Achterberg and Marsh comb.n., and Pl. tico sp.n.), and Sabinita gen.n. (S. mexicana sp.n.). The origin of the gall-associated doryctine clade was estimated to have occurred during the middle Miocene to early Oligocene, 16.33–30.55 Ma. Our results support the origin of true gall induction in the Doryctinae from parasitoidism of other gall-forming insects. Moreover, adaptations to attack different gall-forming taxa on various unrelated plant families probably triggered species diversification in the main Allorhogas clade and may also have promoted the independent origin of gall formation on at least three plant groups. Species diversification in the remaining doryctine taxa was probably a result of host shifts within a particular plant taxon and shifts to different plant organs.

Two new species of the parasitoid wasp genus Spathius Nees (Braconidae: Doryctinae) from Mexico, S. mexicanus sp. n. and S. chamelae sp. n., are described and illustrated. These represent the second and third described species of this highly diverse Old World genus in the Neotropics, and the first described species recorded for the Mexican territory.

The genus Monarea Szépligeti is recorded from Mexico for the first time. A new species, Monarea fridae sp. nov., is described and illustrated from the states of Morelos, Puebla and Jalisco, Mexico. The phylogenetic placement of the genus is investigated based on nuclear (28S) and mitochondrial (COI) DNA sequence data. Based on the relationships recovered, Monarea is transferred to the tribe Holcobraconini, which is also supported by features of the internal ovipositor structure and the venom glands and reservoir. A key to the four currently recognised species of Monarea is provided.

The emerald ash borer, Agrilus planipennis, native to Asia is a devastating pest of ash in North America and European Russia. There are several parasitoids of A. planipennis recorded in Asia and North America, but none previously in Europe and European Russia. Eighty two specimens of the ectoparasitoid Spathius polonicus Niezabitowski (Hymenoptera: Braconidae: Doryctinae) (23 adults, 56 larvae and three pupae) were found in the remains of A. planipennis larvae at five localities in Moscow Province in October 2013 - May 2014. S. polonicus is rare but widely distributed and mainly a Western Palaearctic species. It seems that the level of parasitism could be relatively high: in nature, more than 50% of the last instar larvae of A. planipennis examined were killed by S. polonicus. We collected 24 live last instar larvae and prepupae and the remains of 30 last instar larvae of A. planipennis previously parasitized by S. polonicus. S. polonicus may be suitable for the biocontrol of A. planipennis both in Europe and North America, because it is a native of the temperate climate zone. The potential of this parasitoid for biological control needs special investigation.

The types and undescribed material of the hymenopteran fossils of the Insect Bed of the Bembridge Marls from the Isle of Wight (UK) are critically revised and studied. A total of 1460 fossils are recorded and attributed to 20 families: Gasteruptiidae s.l. (1); Proctotrupidae (3); Diapriidae (24); Cynipidae (7); Figitidae (6); Pteromalidae (1); Agaonidae (3); Scelionidae (12); Platygastridae (2); Ichneumonidae (32); Braconidae (75); Bethylidae (3); Crabronidae (2); Sphecidae (1); Apidae (2); Scoliidae (1); Tiphiidae (2); Vespidae (4); and Formicidae (1220). Described as new are 51 species, 13 genera, two tribes and two subfamilies. Minimum number of species recorded (either as described species or representing higher taxa with no described species in the assemblage) is 118. The composition of the hymenopteran assemblage is most similar to that of Baltic amber and indicative of a well forested territory, as well as of a humid, equable (aseasonal but not very hot) climate, more typically equable than in the Baltic amber source area, judging from the absence of Aphidiinae and scarcity of aphids.
