“…Using an integrative taxonomy approach (Al Khatib et al ., 2014; Baur et al ., 2014; Fusu, 2017; Gebiola et al ., 2017), our study unambiguously evidences the presence in the Mediterranean region (France, Italy, Portugal) of a third species of Ophelimus that threatened Eucalyptus plantations. This new species was also found in its supposed native area (Australia) where it was not until now described.…”

We report here for the first time the presence ofOphelimus mediterraneussp. n. in Mediterranean Europe. This species appears to be closely related toOphelimus maskelli, a well-known invasive pest ofEucalyptus. Based on molecular (cytochrome oxidase I, 28S), morphological (multivariate ratio analysis) and bio-ecological investigations, our study gives unambiguous relevant criteria that allow the discrimination between these two species. A full description ofO. mediterraneussp. n. is also provided. The geographic distribution ofO. mediterraneussp. n. as well as its impact onEucalyptusspecies needs to be more widely assessed since its presence may have been confused withO. maskelliin their sympatric introduced areas. Further investigations of potential parasitoids in the native area may thus be welcomed to evaluate classical biological control achievability.

“…Eupelmus vesicularis, a chalcid wasp long considered as one of the most polyphagous species, with more than 200 hosts from 4 insect orders, it was rather a problem of identification due to morphological similarities. Indeed, the species previously named E. vesicularis turned out to be actually a group of at least five species (Fusu, 2017). Cryptic species have been also identified among braconid species parasitizing lepidopteran [e.g., Cotesia melitaearum and C. acuminata (Kankare et al, 2005) and Cotesia flavipes complex (Muirhead et al, 2012)] or aphids [e.g., Aphelinus varipes species complex (Heraty et al,FIGURE 3 | Host plant preference.…”

Western European Populations of the Ichneumonid Wasp Hyposoter didymator Belong to a Single Taxon

Hyposoter didymator (Hymenoptera, Ichneumonidae) is a generalist solitary endoparasitoid of noctuid larvae. In the present work, we tested whether populations of H. didymator were divided in several genetically distinct taxa as described for many other generalist parasitoid species, and whether differences in H. didymator parasitism rates were explained by the insect host species and/or by the plant on which these hosts were feeding on. The genetic analysis of natural populations collected in different regions in France and Spain on seven different insect hosts and seven different host plants (775 individuals) showed that H. didymator populations belong to a unique single taxon. However, H. didymator seems to be somewhat specialized. Indeed, in the fields it more often parasitized Helicoverpa armigera compared to the other host species collected in the present work. Also, H. didymator parasitism rates in field conditions and semi-field experimental studies were dependent on the host plants on which H. armigera larvae are feeding. Still, H. didymator can occur occasionally on non-preferred noctuid species. One hypothesis explaining the ability of H. didymator to switch hosts in natura could be related to fluctuating densities of the preferred host over the year; this strategy would allow the parasitoid to avoid seasonal population collapses.

“…include Megastigmidae (Janšta et al 2018), but they are treated here as a single taxon because relationships of the latter group with other chalcid families remain uncertain.

Finally, n = 8 to 10 were also detected in certain Eupelmidae and Eulophidae (Fusu 2008b(Fusu , 2017Gokhman and Nishkomaeva 2018).…”

An overview of the current knowledge of chromosome sets of the parasitoid superfamily Chalcidoidea is given. Karyotypes of approximately 240 members of this group, i.e. just above one percent of described species, are studied up to now. Techniques for obtaining and analyzing preparations of chalcid chromosomes are outlined, including the so-called “traditional” and “modern” methods of differential staining as well as fluorescence in situ hybridization (FISH). Among the Chalcidoidea, the haploid chromosome number can vary from n = 3 to n = 11, with a clear mode at n = 6 and a second local maximum at n = 10. In this group, most chromosomes are either metacentric or submetacentric, but acrocentrics and/or subtelocentrics also can predominate, especially within karyotypes of certain Chalcidoidea with higher chromosome numbers. The following main types of chromosomal mutations are characteristic of chalcid karyotypes: inversions, fusions, translocations, polyploidy, aneuploidy and B chromosome variation. Although karyotype evolution of this superfamily was mainly studied using phylogenetic reconstructions based on morphological and/or molecular characters, chromosomal synapomorphies of certain groups were also revealed. Taxonomic implications of karyotypic features of the Chalcidoidea are apparently the most important at the species level, especially among cryptic taxa.
