Hymenoptera taxonomy and phylogeny

X-ray microanalysis of the ovipositor and mandibles of various hymenopterous insects has revealed the presence in many species of up to 10% wt/wt of either zinc or manganese in the cuticle. These metals appear to be involved in cuticular hardening, so helping to reduce abrasive wear. Zinc is found in the ovipositors o…

Microgastrine wasps are among the most species-rich and numerous parasitoids of caterpillars (Lepidoptera). They are often host-specific and thus are extensively used in biological control efforts and figure prominently in trophic webs. However, their extraordinary diversity coupled with the occurrence of many cryptic…

The parasitoid wasp subfamily Braconinae is dominated by the type genus Bracon, a genus which probably now contains more than 1000 described species and no reliable subgeneric groupings. By analysing 28S D2-3 rDNA sequences in representative braconines we show that the genus is paraphyletic. It is unlikely that suffic…

Human dispersal of organisms is an important process modifying natural patterns of biodiversity. Such dispersal generates new patterns of genetic diversity that overlie natural phylogeographical signatures, allowing discrimination between alternative dispersal mechanisms. Here we use allele frequency and DNA sequence…

An electron microscopic survey of antenna cleaner morphology, mainly in non‐aculcate Hymenoptera, is presented. Modified, scale‐ or paddle‐shaped setae on the fore basitarsus were found to be widely distributed throughout the order, but were particularly well developed in the Xyeloidea. Megalodontoidea, Blasticotomida…

Grooming behaviours from representatives of 36 families of Hymenoptera were video recorded and analysed. Thirty-three distinct types of grooming movements were recognized. The evolutionary pattern of each behaviour is discussed. Some behaviours displayed consistent variation between taxa, and appear to be informative…

The mealybug genus Ferrisia Fullaway is revised to include 18 species, based on morphological and molecular data. Wedistinguish the widespread pest species F. virgata (Cockerell) from morphologically similar species and provide a reviseddescription and illustration for the adult female of F. virgata. We resurrect Dact…

Hamuli are hook-like setae on the anterior margin of the hind wing which interlock with the recurved posterior edge of the fore wing in the Hymenoptera during flight, making them functionally two winged. The possession of hamuli is an autapomorphy for the Hymenoptera. Three types of hamuli are distinguishable: basal h…
