“…The genus Achrysocharoide s Girault, 1913 (= Enaysma Delucchi, 1954) belongs to the subfamily Entedoninae of the chalcidoid family Eulophidae. The 48 species described are mostly from temperate regions, with 17 from Europe, 18 from north America (Yoshimoto, 1977; Kamijo, 1991), 11 from Asia (Bryan, 1983; Hansson, 1983, 1985; Kamijo, 1990a, b) and two from Australia (Boucek, 1988). Eleven Achrysocharoide s species are known to occur in the British Isles (Askew & Ruse, 1974; Bryan, 1980) and these have been divided into two taxonomic groups (Graham, 1959; Bryan, 1980; Hansson, 1983).…”

We studied host selection and exploitation, two crucial aspects of parasite ecology, in Achrysocharoides parasitoid wasps, which show remarkable host specificity and unusual offspring sex allocation. We estimated a molecular phylogeny of 15 Achrysocharoides species and compared this with host (plant and insect) phylogenies. This tri‐trophic phylogenetic comparison provides no evidence for cospeciation, but parasitoids do show phylogenetic conservation of the use of plant genera. Patterns of sequence divergence also suggest that the parasitoids radiated more recently (or evolved much faster) than their insect hosts. Three main categories of brood production occur in parasitoids: (1) solitary offspring, (2) mixed sex broods and (3) separate (split) sex broods. Split sex broods are very rare and virtually restricted to Achrysocharoides, while the other types occur very widely. Our phylogeny suggests that split sex broods have evolved twice and provides evidence for a transition from solitary to mixed sex broods, via split sex broods, as predicted by theory.

“…The two new species of Achrysocharoides described here are from North America and the genus was initially recorded from this region by Miller (1962) , as the genus Enaysma Delucchi, including six new species from Canada which were placed in the same subgenus ( Pentenaysma Graham). Yoshimoto (1977) synonymized Enaysma with Achrysocharoides , and added nine species (six newly described) to the six described by Miller.

Species recognition through wing interference patterns (WIPs) in Achrysocharoides Girault (Hymenoptera, Eulophidae) including two new species

Wing interference patterns (WIPs) are shown to be an important tool for species recognition in the genus Achrysocharoides Girault (Hymenoptera: Eulophidae). This is demonstrated by combining information from two previously published papers, comprising two cases of cryptic species, and by new material including the description of two new species, Achrysocharoides maieri and Achrysocharoides serotinae from North America. The cryptic species were initially separated through their distinct male WIPs. Subsequent analyses of the external morphology uncovered additional morphological differences supporting the original findings through WIPs, and biological data further strengthened the identity of these species. The new species described here also differ in their WIPs but the WIPs are similar in both sexes. Thus they provide a strong link between male and female and demonstrate that WIPs can also be useful for species recognition when the sexes are otherwise difficult to associate. Both new species are from Connecticut, USA, and were reared from Phyllonorycter propinquinella (Braun) (Lepidoptera: Gracillariidae) on black cherry (Prunus serotina); Achrysocharoides maieri has also been reared from Ph. nr crataegella on pin cherry (Prunus pensylvanica). To facilitate the identification of the new species they are included in a previously published key to North American species of Achrysocharoides. As a supplement to colourful WIPs we also demonstrate that grey scale images of uncoated wings from scanning electron microscopy can be used for visualization of the thickness distribution pattern in wing membranes.

“…These correspond with the two species-groups, atys - and latreilleii -groups, which Bryan (1980a) introduced for the European species, thus abandoning the formal subdivision into subgenera. Yoshimoto (1977) divided the Nearctic species into two species-groups, the gahani - and guizoti -groups. Kamijo (1991) transferred some of the Nearctic species from the guizoti -group to either of the two newly erected clypeatus - and titiani -groups, and removed the remaining species in the guizoti -group to the latreilleii -group, thus terminating the guizoti -group.…”

Achrysocharoides Girault (Hymenoptera, Eulophidae) new to tropical America, with eight new species

The genus Achrysocharoides Girault is here reported for the first time from tropical America. Included are ten species, eight newly described: Achrysocharoides asperulus, Achrysocharoides callisetosus, Achrysocharoides cuspidatus, Achrysocharoides foveatus, Achrysocharoides infuscus, Achrysocharoides mediocarinatus, Achrysocharoides purpureus, Achrysocharoides sulcatus, and two already known: Achrysocharoides ecuadorensis (Hansson) and Achrysocharoides gliricidiae (Hansson & Cave). All species are included in an identification key, diagnosed, described and illustrated. Only one of the species, Achrysocharoides gliricidiae, has a host record, an endoparasitoid in a leafmining Gracillariidae (Lepidoptera) on Gliricidia sepium (Fabaceae), thus conforming to the biology of extralimital Achrysocharoides species. The genus Kratoysma Bouček is here established as a junior synonym of Achrysocharoides, and the following species previously in Kratoysma are here recombined to Achrysocharoides: Kratoysma citri Bouček, Kratoysma ecuadorensis Hansson, Kratoysma gliricidiae Hansson & Cave, Kratoysma longifacies Hansson, Kratoysma nepalensis Hansson, Derostenus usticrus Erdös.
