The doryctine tribe Rhaconotini (Hymenoptera: Braconidae) is a cosmopolitan group of parasitoid wasps that currently comprises 13 valid genera. Despite the extensive taxonomic studies carried out for this tribe, its generic limits are still unclear due to the considerable variation of its diagnostic morphological features. Here we assessed the evolutionary relationships among representative species of eight rhaconotine genera based on mitochondrial and nuclear DNA sequence data. We also performed ancestral character reconstruction analyses of morphological features that are diagnostic at the genus level and assessed the times of origin and main diversification events in the tribe. The Rhaconotini was significantly supported as monophyletic. The widely distributed, speciose genus Rhaconotus Ruthe as well as Ipodoryctes Granger were recovered as non-monophyletic. Rhaconotus species with five visible metasomal tergites were nested in a single clade with the monotypic Aptenobracon Marsh, which also has this morphological feature. Most Rhaconotus species with six or more visible tergites were intermingled with other Oriental and Afrotropical genera that share this condition. The ancestral character reconstruction analyses of the remaining morphological features showed that they probably were gained and lost repeatedly during the evolution of the group. The origin and early diversification events in the Rhaconotini were estimated to occur during the late Eocene to mid-Miocene. Our results highlight the importance of assessing the evolution of diagnostic morphological features to improve the supraspecific classification of insect taxa with extensive morphological homoplasy.

The endemic New Zealand cyclostome braconid wasp genus Metaspathius Brues, which was previously only known from a single specimen, an apterous female, is revised. Four new species, including three with fully winged females, are described and illustrated: Metaspathius chathamicus Ward, sp. nov.; M. hemipterus Belokobylskij, sp. nov.; M. kuscheli Ward & Belokobylskij, sp. nov.; and M. sharkeyi Quicke & Butcher, sp. nov. Metaspathius apterus Brues is illustrated. The first host record for the genus is provided: Metaspathius kuscheli sp. nov. is recorded as a larval parasitoid of the New Zealand endemic weevil Phrynixus astutus Pascoe, 1876 (Curculionidae). DNA sequence data (CO1 and 28S) for two of the species are included in an analysis of a broad range of cyclostome Braconidae with emphasis on basal taxa. The results show that Metaspathius belongs to a clade restricted to New Zealand within the heterogeneous basal subfamily Mesostoinae van Achterberg, 1975. A revised morphological diagnosis of the Mesostoinae is presented in the light of the discovery that Metaspathius is a member. The relationships of the Maxfischeriinae are discussed in the light of molecular findings.

The tribe Holcobraconini (Braconidae: Doryctinae) is a group of parasitoid wasps mainly found in the tropical and subtropical regions of the world. It contains seven genera (Holcobracon Cameron, Ivondrovia Shenefelt & Marsh, Liodoryctes Szépligeti, Monarea Szépligeti, Nervellius Roman, Odontobracon Cameron and Zombrus Marshall), most of which are characterized by having the m-cu vein of the hind wing long and strongly curved towards the apex of wing. Some studies, however, found that three doryctine genera that lack the above feature (Binarea Brullé, Liobracon Szépligeti and Odontodoryctes Granger) might be closely related to holcobraconines. Here, we reconstructed the phylogenetic relationships among species of six holcobraconine genera and the three putative closely related genera using four gene markers and estimated the times of origin and diversification within the tribe. The holcobraconine genera were intermingled in a clade with the above three genera. Liobracon and Zombrus were not recovered as monophyletic. Acanthodoryctes Turner, Antidoryctes Belokobylskij & Quicke and Priosphys Enderlein were also included within the Holcobraconini based on morphology. Based on molecular evidence and on morphological examination of the genera involved, Holcobraconini is proposed to comprise 13 genera for which we include morphological diagnoses. The origin of the tribe probably occurred during the late Palaeocene to mid Eocene, 44.43 to 58.15 Mya. At least two main dispersal events from the Ethiopian to the other biogeographic regions could have led to the current geographic distribution of the Holcobraconini associated with the global increase of temperature during the Late Palaeocene to Middle Eocene.

A new genus, Cerritulus gen. nov., with type species, C. forticrura sp. nov., are described from French Guiana based on a single specimen that is considerably distinct morphologically from all known Neotropical genera. The new genus is only partially similar to the enigmatic, monotypic Asian genera Ceylonspathius Belokobylskij and Termitospathius Belokobylskij, whose species were collected inside termite nests. We provide colour pictures for the type species of the above three genera.
